How To Enable Freesync On The Monitor
Demo: How to Enable AMD FreeSync on NVIDIA GPUs?
To be honest, we have long suspected that NVIDIA might support the FreeSync card and monitor synchronization technology on their own cards. But, apparently, a political decision was made against such support. So the owners of cards based on NVIDIA GPUs have no choice but to buy monitors with G-Sync support. Accordingly, if you have a card based on AMD GPU, you will have to be content with a monitor with FreeSync support.
The range of G-Sync and FreeSync monitors is different. we found about 300 monitors with FreeSync support, in the case of G-Sync the number of models is much smaller. about 50 There are especially many monitors in the middle price segment, and with almost identical characteristics. But, as a rule, monitors with G-Sync support are much more expensive. The flagship can be called the ASUS PG27UQ monitor (test), which supports 144Hz, UHD, HDR and G-Sync, but also.
It looks like enthusiasts have discovered a trick with which to get an NVIDIA GPU card to work with a FreeSync monitor. It was first discovered by users of bryf50, which has AMD’s Radeon Pro WX 4100 and NVIDIA’s GeForce GTX 1080 Ti cards. In the Battle for Azeroth expansion of the popular World of Warcraft game, when installing two cards, you can choose which GPU to render on. The monitor was connected to a Radeon Pro WX 4100 card, but the rendering was carried over to a GeForce GTX 1080 Ti. As a result, the picture was displayed through an AMD card with active FreeSync support.
Another user survfate used a Windows 10 feature that allows you to switch between two or more GPUs under the operating system. Survfate used AMD Ryzen 3-2200G APU and GeForce GTX 1060 card; the integrated graphics core of the AMD processor has been listed as a power saving GPU (Power Saving GPU) and the NVIDIA. high performance GPU (High Performance GPU). By right clicking on the executable file, you can choose on which GPU the game will be launched. After starting the game, the frame buffer is transferred from the NVIDIA card to the graphics core of the AMD processor, after which it is displayed on the monitor.
Our colleagues at PCPerspective have tested a similar configuration. First of all, they were interested in the delays associated with the transfer of the frame buffer from one card to another. In the native FreeSync configuration (with a Nixeus EDG-27 monitor), the input lag is 29ms. In G-Sync configuration (with ASUS ROG Swift PG27Q monitor). 24.9 ms. FreeSync support on GeForce GTX 1080 gives 31.9ms latency.
The question arises as to how useful such a configuration is in everyday use. One of the requirements is an AMD GPU card or an integrated GPU, as well as an NVIDIA GPU card. It makes sense that the NVIDIA GPU should be more powerful. this must also be taken into account. Otherwise, no modifications are required. no need to replace dlls or run patches.
There is an easy way for NVIDIA and Microsoft to close the discovered trick of FreeSync running on NVIDIA GPUs. But is it really necessary? However, not every user has an AMD GPU or an integrated GPU along with an NVIDIA GPU card. Therefore, the number of users who activate FreeSync on NVIDIA GPU is close to zero.
And again the question arises: will NVIDIA ever activate FreeSync support on its cards? At the moment, this is unlikely to be expected, since NVIDIA argues support for G-Sync by the fact that the technology is technically more advanced.
Enabling G-Sync on FreeSync Monitor
First, let’s take a look at exactly how you enable adaptive sync support for uncertified monitors. Open Nvidia Control Panel, go to section “Set up G-Sync and select your FreeSync monitor. Then make sure both the Enable G-Sync, G-Sync compatible and Enable settings for the selected display model are checked. The second checkbox will NOT appear if your monitor is a G-Sync certified monitor. Then click “Apply” and your monitor will turn on with adaptive sync.
In some cases, you may need to go to the Manage 3D settings and select G-Sync Compatible from the Monitor technology drop-down list, but this was not required on all monitors we tested. It’s also important to note that FreeSync must be enabled on the monitor itself (usually via the OSD menu). Some monitors have a switch that allows you to turn FreeSync or Adaptive Sync on / off, you need to set it to “on”.
And a final note. Unlike G-Sync monitors that work with Nvidia GPUs up to the GeForce 600 series, G-Sync compatible and FreeSync monitors only work with Nvidia GTX 10 or newer. We tested many monitors with a GeForce RTX 2080 Ti, but all other Pascal cards should work as well. We believe this is due to the fact that Pascal is the first GPU architecture to support both adaptive sync and G-Sync, while older architectures only supported G-Sync.
Using FreeSync with Nvidia Cards
To the surprise of many, Nvidia has stepped back from its stronghold of G-Sync and allowed Nvidia GPU owners to use adaptive sync across a wide range of monitors that support FreeSync. This feature was announced during CES 2019 by CEO Jensen Huang and was included in the latest GeForce drivers this week.
You can probably argue: “wide range is too loud, because Nvidia barely supported only 12 monitors!” But actually it is not. Nvidia’s statement about this feature is a bit misleading, so in this article we’ll try to explain it.
Nvidia driver support for adaptive sync monitors has four levels. Yes four.
First of all, this is G-Sync Ultimate. the new name for G-Sync HDR.
G-Sync Ultimate certified monitors have built-in Nvidia G-Sync HDR and support a full range of HDR features. G-Sync Ultimate monitors include Acer Predator X27, Asus ROG Swift PG27UQ and new HP Omen X Emperium 65.
Then. the usual G-Sync.
These are monitors that have served us for many years, and that include a G-Sync module, but do not support G-Sync HDR. These are adaptive sync monitors that work with and only Nvidia cards, and are more expensive than their FreeSync counterparts.
Next, let’s move on to “G-Sync compatible” monitors.
These are the FreeSync monitors that meet all of Nvidia’s stringent requirements. They have G-Sync modules, but they support VESA Adaptive Sync, so they also work with AMD GPUs. Latest Nvidia drivers allow these certified monitors to run adaptively sync on Nvidia GPUs by default.
So far, Nvidia has announced 12 monitors are fully G-Sync compatible, as you can see in the picture above. If you own any of THESE monitors and you have installed the latest Nvidia driver, Adaptive Sync will be enabled automatically and you can use it just like you would with any G-Sync monitor.
According to Nvidia, G-Sync compatibility is inferior to regular G-Sync. The table below shows that G-Sync monitors are certified with a wide range of image quality tests, full variable refresh rate (VRR) range, Variable Overdrive persistence, and factory color calibration. However, nothing prevents any G-Sync compatible monitor from being factory calibrated or having a full VRR (Variable Refresh Rate) range. It’s just that Nvidia does not require THESE conditions from the manufacturer in order to get the “G-Sync compatible” sticker, while G-Sync monitors must have these features.
And finally, the fourth level, in which Nvidia only mentions in passing, is the ability to use any FreeSync or VESA Adaptive Sync monitor with an Nvidia card using a switch on the Nvidia control panel.
According to Nvidia, this applies to those “VRR monitors that have not yet been tested for G-Sync compatibility”, and when enabled, “it may work, or it may work partially or not at all.” Of course, only certified monitors are guaranteed to work, and according to Nvidia’s results. 12 monitors supported out of 400 tested. your chances may look bleak, however the drivers do NOT limit you and in fact all adaptive sync monitors are supported. All you have to do is enable the feature in the settings.
During her talk at the show, Nvidia tried to convince people that their program for certifying G-Sync compatible monitors is necessary, since uncertified monitors are allegedly rife with problems. They demonstrated flickering and dying monitors, trying with THESE examples to tarnish the entire FreeSync ecosystem. Nvidia says its G-Sync certified compliant monitors do not have these issues, while any uncertified monitors may.
As soon as we saw this, we immediately considered this statement to be nonsense. Simply because the problems demonstrated are NOT related to the FreeSync or VESA Adaptive Sync standards in any way; they are NOT problems inherent in technology. These are just problems related to the quality of monitors. It’s no secret that some FreeSync monitors, especially early models, are too good and do have flaws such as flickering even on AMD GPUs.
But these monitors are just rubbish. It seems to us that if you buy a monitor that flickers or goes blank, then such a Defective Product will simply be subject to a return. Of course, there is a possibility that adaptive-sync monitors that run great on AMD GPUs will have some kind of issue on Nvidia GPUs. And then it would be possible to reproach Nvidia for inappropriate implementation of support for adaptive synchronization, but, as in all implementations, some errors and problems are always possible.
Testing FreeSync on GeForce
So far we have tested seven FreeSync monitors with an Nvidia GPU. All of these monitors have been tested by us before and have shown flawless performance with AMD GPUs. So no Shimmer, blanking or second problems. They work fine. We would like to test more monitors, given that there are over 500, but so far we only have these seven at our disposal. Nevertheless, this is a pretty good sample size today.
The purpose of testing was to find out if there are any differences between enabled and disabled adaptive sync with an Nvidia GPU, and if there are any differences when compared to a FreeSync monitor connected to an AMD GPU. This involved testing the monitor in the frame rate range to see how it behaves within and outside the refresh rate range.
The first monitor we tested was the Acer KG251QF, a budget 24-inch 1080p monitor with refresh rates ranging from 30Hz to 144Hz. This is a great monitor for the price, and it’s safe to say that we did NOT find any issues with it with adaptive sync enabled on the Nvidia GPU. There is flicker, there is blanking, nothing like that. It worked exactly the same as when connected to an AMD GPU. So, offset.
The second monitor was the BenQ EL2870U. a 4K 60Hz panel with a thin 40 to 60Hz refresh rate range. This monitor also performed well, although the refresh range is too narrow to support Low Frame Rate Compensation (LFC). Therefore, when the frame rate dropped below 40, Adaptive Sync would NOT function anymore and there would be tearing or lagging depending on whether Vsync was turned on or off. This behavior was expected and occurs with AMD GPUs as well. Therefore, we again evaluate the result as successful.
The next monitor was the Viotek GN24C, another 24-inch 1080p monitor, but this time with a VA panel and a 48 to 144 Hz refresh rate range. Again, this monitor worked great and, thanks to its wide refresh rate range, it also supported LFC.
Low Framerate Compensation (LFC) is also a feature we were particularly curious to see worked properly on GeForce GPUs. If Nvidia was lazy, it would simply turn off adaptive sync when the frame rate drops below 48Hz. However, this is not the case, Nvidia properly supports LFC with monitors that support this feature, so when the frame rate drops below 48 FPS, the monitor operates at multiples of the frame rate, duplicating them.
For example, if the frame rate in the game is 37 FPS, the monitor will refresh at 74 Hz, showing each frame twice. So it’s nice to see that one of the key adaptive sync features that Nvidia happily applies to G-Sync monitors also works here without any restrictions.
Two second monitors showed a similar result: the AOC C27G1, a 27-inch 1080p monitor with a refresh range of 48 to 144 Hz, and the Viotek GN32LD, a 32-inch 1440p monitor, also with a refresh range of 48 to 144 Hz. Both monitors worked fine, including in LFC mode.
Then came PhilIPs Momentum 43, a 43-inch 4K monitor with 48 to 60Hz refresh range and HDR support. It has an LFC due to its narrow refresh rate range, but otherwise this panel worked as expected without issue.
We are pleased to note that adaptive sync support works even when HDR is enabled; the choice of one or the other is independent, HDR does not affect adaptive sync capabilities, which is good news for those interested in an HDR monitor but don’t want to buy a G-Sync Ultimate display.
One of the monitors we tested with FreeSync refused to work with adaptive sync on an Nvidia GPU, but this is not a big surprise. Thing is, the Viotek NB24C only supports adaptive sync over HDMI, while Nvidia GPUs only support adaptive sync over DisplayPort. AMD GPUs can do adaptive sync over both HDMI and DisplayPort, so this monitor has adaptive sync with AMD GPUs, and comments with Nvidia GPUs.
The lack of adaptive sync over HDMI will also disappoint those looking to pair Nvidia GPUs with a number of FreeSync-enabled TVs that have hit the market in recent years. Most FreeSync TVs only have HDMI ports, so again, Nvidia GPU owners will be left out.
So, out of the seven monitors we tested, six showed perfect results, and the seventh was NOT going to show them, since it needs FreeSync via HDMI, aka Nvidia Plasma. Also, it would NOT hurt to test how well Low Frame Rate Compensation (LFC) and HDR will work with adaptive sync on Nvidia GPUs as they do on AMD GPUs.
Should monitors that pass our testing be certified as G-Sync compatible? Difficult to say, not knowing Nvidia’s strict testing guidelines. However, any monitor without LFC support will automatically play. there are many such FreeSync monitors without LFC, including the two we tested today. But I think it’s only important to emphasize that you don’t need to purchase a “G-Sync compatible” monitor to have adaptive sync with your Nvidia card. Buying a “G-Sync compatible” monitor will ensure proper operation and support for features such as LFC, but regular FreeSync monitors will also work fine.
As for the weak points. We don’t have any of those twelve “G-Sync compatible” monitors to test and compare, but having tested a variety of G-Sync monitors in the past, we’ve gotten the same excellent results with uncertified FreeSync monitors. The “G-Sync Compatible” badge simply provides a certain level of quality that you will NOT get with, say, the cheapest FreeSync models.
If you are wondering about input lag, we have NOT found a noticeable difference in its value between enabled and disabled adaptive sync on Nvidia GPUs. Enabling adaptive sync does NOT seem to increase processing time on the GPU side, be it Nvidia or AMD.
You are NOT limited to just one display with adaptive sync support. you can use multiple such displays connected to a single Nvidia GPU, but Adaptive Sync will only work on one of them at a time. This is unlikely to be a problem for most people, but let’s say you have two games running on two different adaptive sync displays, in which case only one of THESE monitors will receive an adaptive sync signal from the corresponding game.
We have not tested any FreeSync 2 monitors in conjunction with an Nvidia GPU, as FreeSync 2. is only an HDR pipeline designed exclusively for AMD, which allows the game to directly interact with the monitor for HDR processing with the lowest latency, and therefore this feature is unlikely to be work with Nvidia GPUs. However, as we mentioned, this won’t usually prevent HDR from working in conjunction with adaptive sync on Nvidia GPUs. So those who bought or are going to buy a FreeSync 2 monitor will get HDR functionality, not HDR FreeSync 2, which only supports a few games.
To summarize, it’s worth recognizing that Nvidia’s decision to support FreeSync is a good thing for consumers and the industry as a whole. We hope that this will increase the range of available adaptive sync monitors for owners of the most popular GPUs on the market. Why pay extra for a G-Sync module when there is an equivalent FreeSync, but before worrying about VRR, make sure that the gaming monitor you buy is truly of a high quality standard.
Enabling Vertical Sync in NVIDIA Settings
Open NVIDIA Control Panel and go to “Manage 3D Settings” “(3D Parameter Control). In the Global Setting section, find the Vertical Sync option and set the option to “On”.
Thanks to this, Vsync will always be ready to turn on if the FPS falls below 30 FPS, and a monitor with G-SYNC technology WOULD NOT be able to handle it.
G-Sync is expensive but effective
Another way from Nvidia. The company has developed special G-Sync monitors that adjust the frequency to match the frequency of the card. That is, if 80 FPS is fed to a G-Sync monitor with a frequency of 120 Hz, then the monitor will lower the frequency to 80 Hz.
Removing all the downsides to vertical sync (stattering, tearing, control lag), G-Sync is a very good option. But, at the same time, it is very expensive, since G-Sync only works on monitors with a pre-installed chip from Nvidia and requires increased power.
Every gamer knows what V-Sync is. This function synchronizes the image frames in such a way as to eliminate the screen tearing effect. If you turn off vertical sync on a regular monitor, then the input lag (delay) will decrease, while you will notice that the game will respond better to your commands, but the frames should not be properly synchronized and will reach screen tearing.
V-Sync eliminates screen tearing, but at the same time increases the latency of the picture output before the control, so it becomes less comfortable to play. Each time we move the mouse, it appears that the movement effect occurs with a slight delay. And this is where the G-SYNC function comes to the rescue, which allows you to eliminate both of these disadvantages.
What do I do with V-SYNC if I have G-SYNC? Leave it on or turn it off?
This is the most common G-SYNC monitor dilemma. It is generally accepted that this technology completely replaces the classic V-SYNC, which can be completely disabled in the NVIDIA Control Panel or simply ignored.
First you need to understand the difference between them. The task of both functions is theoretically the same. to overcome the screen tearing effect. But the mode of action is significantly different.
V-SYNC synchronizes frames to match the monitor’s constant refresh rate. Therefore, the function acts as an intermediary, capturing the picture and, accordingly, the display of the frame, so as to adapt them to a constant frame rate, thereby preventing image tearing. In total, this can lead to input lag (delay), because V-SYNC must first “capture and arrange” the image, and only then display it on the screen.
G-SYNC works exactly the opposite. Adjusts NOT the image, but the monitor refresh rate to the number of frames displayed on the screen. Everything is done in hardware using the G-SYNC module built into the monitor, so there is no additional delay in the display of the picture, as is the case with vertical sync. This is its main advantage.
The whole problem is that G-SYNC works well only when the FPS is in the supported refresh rate range. This range covers frequencies from 30 Hz up to the maximum the monitor can support (60 Hz or 144 Hz). That is, this technology works to its fullest when the FPS does NOT fall below 30 and does NOT exceed 60 or 144 frames per second, depending on the maximum supported refresh rate. Looks very good, Below is an infographic created by BlurBusters.
What happens if the frames per second goes outside this range? G-SYNC will NOT be able to set up screen refresh, so anything out of range won’t work. You will find exactly the same problems as on a regular monitor without G-SYNC and classic vertical sync will work. If it is turned off, screen tearing will occur. If enabled, you will NOT see the break effect, but an IPut lag (delay) will appear.
Therefore, it is in your best interest to stay within the G-SYNC refresh range, which is at least 30 Hz and the maximum of how much the monitor supports (most often 144 Hz, but there are also 60 Hz displays). How to do it? Using the appropriate vertical sync options, as well as limiting the maximum number of FPS.
What, then, is the conclusion from this? In a situation where the number of frames per second falls below 30 FPS, you need to leave Vsync still enabled. These are rare cases, but if it comes down to them, V-SYNC ensures that there will NOT be any tearing effect. If the upper limit is exceeded, then everything is simple. you need to limit the maximum number of frames per second so as not to approach the upper limit, at the crossing of which V-SYNC is turned on, thereby ensuring continuous operation of G-SYNC.
Therefore, if you have a 144Hz monitor, you need to turn on the FPS limit at 142 so as not to come close to the upper limit. If the monitor is 60 Hz, set the limit to 58. Even if the computer is able to do more FPS, it will not do it. Then V-SYNC will NOT turn on and only G-SYNC will be active.
Vertical sync. cheap and fun
Vertical Synchronization (V-Sync) is a kind of “crutch” that rarely helps on its own. The principle of operation is simple: it slows down the card by forcing it to release as many frames per second as the monitor can produce. Thus, “extra frames” does not appear and the card is synchronized with the monitor. But there are problems: if the possible FPS significantly exceeds the specified synchronization, then the game reacts worse to the player’s actions. many complain that it seems that the character (regardless of the game) moves “like in milk”.
However, the problem is NOT solved with frames that take longer to render and because of which the card produces less per second than the monitor can show. Because V-Sync in this case reduces the number of displayed frames in a multiple of the monitor frequency. eg, If you have a monitor with 60 Hz, and the card outputs 55 frames per second, then V-Sync will cut the Displayed number of frames to 30 so that the picture goes smoother. As a result, FPS drops and the feeling becomes even worse.
Adaptive sync is the big brother of V-Sync
Nvidia has developed adaptive sync to replace vertical sync. Its principle of operation is simple. if the card produces more than 60 frames per second, V-Sync turns on automatically. If the frames are less than necessary, vertical sync is disabled. If the frequency is higher, vertical sync works and removes image tearing. If the frequency is lower. It does not block at a specific value and (in theory) everything works well.
However, in practice, this method does not always help and vertical synchronization problems can still occur.
Enabling G-SYNC in NVIDIA Control Panel
Let’s start with the simplest basic solution, that is, from the moment the G-SYNC module is turned on. This can be done using the NVIDIA Control Panel. Right click on the desktop and select NVIDIA Control Panel.
Then go to the Display. G-SYNC Settings tab. Here you can enable the technology using the “Enable G-SYNC” field. mark it.
Then you can specify whether it will only work in full screen mode, or can also activate in games launched in windowed mode or full screen window (no borders).
If you select the “Enable G-SYNC for full screen mode” option, then the function will only work in games that have a Full screen mode set (this option can be changed in the settings of specific games). Games in windowed or full screen mode will NOT use this technology.
If you want “windowed” games to also use G-SYNC technology, then enable the “Enable G-SYNC for windowed and full screen mode” option. When this option is selected, the function intercepts the currently active window and imposes its action on it, we activate support for the changed screen refresh in it. You may need to restart your computer to activate this option.
How to check that this technology is enabled. To do this, open the Display menu at the top of the window and select the “G-SYNC Indicator” checkbox. This will inform you that G-SYNC is enabled when starting the game.
Then go to the Manage 3D Settings tab in the side menu. In the “Global settings” section, find the “Preferred refresh rate” field.
Set this to “Highest available”. Some games may dictate the refresh rate, which may result in G-SYNC not being fully utilized. Thanks to this option, all game settings will be ignored and the option to use the maximum refresh rate of the monitor, which is most often 144Hz in devices with G-SYNC, will always be enabled.
In general, this is the basic setting you need to do to enable G-SYNC. But, if you want to take full advantage of the potential of your equipment, then you should read further instructions.
Limit FPS to a value lower than the maximum refresh rate
The best way to limit frames per second is to use RTSS (RivaTuner Statistics Server). By far the best solution is to use a limiter built into the game, but not everyone has one.
Download and run the program, then in the list of games on the left side, check the Global field. Here you can set a common limiter for all applications. On the right side, find the “Framerate limit” field. Set the limit here for 144Hz monitors. 142 FPS, respectively, for 60Hz devices. 58 FPS.
When the limit is set, there will be no delay with the activation of the classic vertical sync and the game will become much more comfortable.
For a comfortable game, it is always important not only the quality of the picture (which we talked about separately), but also its refresh rate, which depends on many factors. the monitor model, computer power and the synchronization method. In this article, we will look at the existing types of synchronization: vertical and adaptive sync, as well as G-Sync and FreeSync, in order to understand what is the difference between them and what is better to use.
What is G-SYNC?
A fairly expensive but effective solution for NVIDIA GeForce cards is the use of G-SYNC technology, which eliminates screen tearing without using additional input lag. But for its implementation you need a monitor, which includes the G-SYNC module. The module adjusts the screen refresh rate to the number of frames per second, so there is no additional delay and the effect of screen tearing.
Many users, after purchasing such a monitor, only enable NVIDIA G-SYNC support in the NVIDIA Control Panel settings with the conviction that this is all there is to it. In theory, yes, because G-SYNC will work, but if you want to fully maximize the use of this technology, then you need to enable a number of additional features associated with the appropriate setting of classic vertical sync and limiting the FPS in games to a number fewer than the maximum refresh rate. monitor. Why? You will learn all this from the following recommendations.
Requirements for the use of technology
Without further ado, we can say briefly: support is not available for absolutely all connections between GeForce cards and FreeSync displays. This is not necessarily related to NVIDIA’s intention to use only its own products. It’s just that AMD’s dynamic update feature has requirements that must be met. Therefore, you need to check that the card supports the Corresponding Standards and the display is connected to it via the Corresponding Cable.
For the technology to work properly, you need:
- Pascal series cards (GTX 1000) and higher.
- FreeSync monitor (Not every model is compatible, especially on weaker quality units, problems may arise).
- DisplayPort 1.2a cable connection (HDMI support available).
- GeForce Game Ready Drivers NOT lower than version 417.71.
It is disappointing that the feature can only be activated on Pascal (GTX 1000), Turing (RTX 2000) and newer cards. In comparison, G-Sync even works on a GeForce GTX 600.
Why does FreeSync require a new series of adapters? This is because a DisplayPort 1.2a connection is required, which means that this standard is supported by the Pascal series and newer.
Also, the connection depends on the quality of the monitor. NVIDIA officially tested 400 models with this technology, but only 12 of them were certified for quality and compatibility. But this does NOT mean that only these 12 certified models are suitable for use. the function can be enabled on absolutely all FreeSync monitors connected via a DisplayPort 1.2a cable. And in most cases, it will work. This shows how high the company sets the bar in terms of quality requirements for models for their certification.
How to enable FreeSync technology on Nvidia cards?
Are you using a FreeSync monitor but your computer has an NVIDIA card? It is possible to experience the benefits of AMD technology on this computer configuration. FreeSync can now be enabled on GeForce cards as well, but there are certain limitations.
For a long time NVIDIA did NOT offer any support for FreeSync, that is, dynamic screen refresh. You had to buy AMD cards to be able to use it. GeForce users wanting to take advantage of the dynamic refresh rate could only reach for the exclusive G-Sync technology, which significantly increases the price of the monitor, which is compatible with it.
As a result, NVIDIA provided FreeSync support for GeForce cards. It can be activated using the G-Sync Compatible option, which has been added in the latest drivers. However, there were no certain restrictions.
How to turn on?
The feature can be activated in NVIDIA settings. Follow these steps.
First, enable FreeSync support on the monitor itself. After Turn off your computer and display, unplug the devices’ power cords, and wait 10 seconds before turning them back on.
Once downloaded Right click on your desktop and select NVIDIA Control Panel.
On the left side menu, go to the Manage 3D Settings tab. On the right side of the window, “Global Settings” and “Program Settings” are displayed. We are interested in the first tab.
Find the “Monitor Technology” field in the list and select “G-Sync Compatible”. This value tells the system that the display is compatible and activates the ability to use FreeSync on the screen.
After enabling this option, go to the side menu of the control panel. A new G-Sync Settings tab will now appear in the Display section.
Check the “Enable G-Sync” checkbox here. then check the box “Enable in windowed and full screen mode”. Save changes with the “Apply” button.
Guide to Enable G-sync on FreeSync Monitor
Updating your computer with the latest technology improves your gaming experience only if you can make the most of it. It is understood that the AOC FreeSync monitor stabilizes and enhances picture quality on PCs with AMD cards. However, thanks to the latest technical innovations, the AOC FreeSync monitor can also be G-Sync compatible and works great with NVIDIA cards.
What is monitor sync?
cards are usually unable to maintain a consistent frame rate. in their operation, high peaks in performance can alternate with sudden drops. The frame rate depends on the image that the card displays. For example, quiet scenes without much activity are much less demanding on performance than epic boss fights full of special effects.
When the frame rate of the Map does not match the frame rate of the monitor, certain display problems arise: tearing, delays, or overlaps while the monitor waits for new data or tries to display two different frames as one. To prevent such problems, the card and monitor must be synchronized.
The technology for consistent image quality is called FreeSync and requires an AMD card and FreeSync monitor. At the same time, there is also NVIDIA’s G-Sync technology, which implies the presence of an NVIDIA card and a monitor with G-Sync support.
new generation NVIDIA cards can use G-Sync functionality on select AOC FreeSync monitors. NVIDIA has announced a list of AOC certified monitors that are also G-Sync compatible. If your AOC monitor is not on this list, you can still enable G-Sync and test its performance.
How to enable G-sync on your FreeSync monitor
- Update the NVIDIA driver to at least version 417.71 (earlier versions WILL NOT work).
- Connect your monitor to the card via DisplayPort.
- In the monitor control panel, enable variable refresh rate.
After completing all the above steps, G-Sync will turn on automatically. Otherwise, you can manually enable this feature by taking a few more steps.
- Open the Nvidia Control Panel at the bottom right of the Windows Desktop.
- Select “Display” and click “Set up G-SYNC”.
- Select “Enable G-SYNC Compatible”.
- Select your monitor in “Enable settings for the selected display model”.
- Check “Enable settings for the selected display model”.
- Apply settings.
If the above method didn’t work, you may need to do a few more steps.
- Go to “Manage 3D Settings”, click “Global”, scroll down to “Monitor Technology”, select “G-SYNC Compatible”, then click “Apply”.
- Alternatively you can go to “Change Resolution” on the left and select a Higher Refresh Rate or a different resolution.
You have now successfully enabled G-Sync on your AOC FreeSync monitor. The picture quality will always be perfect and you can get the most out of the gameplay without annoying distortion.
For a complete list of cards that support FreeSync monitors as well as G-Sync compatible monitors, visit the NVIDIA website.
Which response time acceleration option to use?
To access your monitor’s overdrive settings, open the On-Screen Display (OSD) menu and look for the overdrive option, usually under one of the following names: TraceFree (some ASUS monitors), Rampage Response, Overdrive, OD, or simply Response Time.
There should be at least a few options to choose from. Overdrive levels will be named differently depending on the model, and some monitors may have more levels than others.
Usually the levels are labeled as Slow, Normal, Fast, Fast. Low, Medium, High, Highest, or just numbers. The ASUS TraceFree option allows, for example, to adjust the overdrive from 0 to 100 in increments of 10. Some monitors also have the ability to completely disable overdrive.
Now, if you have a modern 60Hz / 75Hz LED backlit monitor, its response time is unlikely to be faster than the display refresh cycle.
In most cases, you will not notice any noticeable ghosting / trail of fast moving objects, even if the overload is set to Off. Or Low, but Medium / Normal usually works best. Overdrive too much can reverse ghosting or throw away pixels, so DO NOT use it unless you experience excessive motion blur in fast-paced games.
Displays with a higher refresh rate require an overload for optimal gaming. To check which acceleration setting is best for your monitor’s refresh rate, we recommend using BlurBusters UFO Halo Test.
It is very important that a gaming monitor has a good overdrive implementation. Some monitors have poorly optimized overdrive, such as the Samsung CHG70, which has only one overdrive preset too strong at a lower frame rate, resulting in noticeable overdrive.
So when looking for a gaming monitor, a simple glance at response times may not be enough. In our monitor reviews, we always consider a display overdrive implementation if it’s worth considering.
Response time and overload: IPS, TN or VA?
Typically, monitor manufacturers simply turn on the GtG (gray to gray) response rate, which is basically 1ms for TN panels and 3-5ms for IPS and VA panels. LG 27GL850 is the first IPS display to achieve GTG speeds of 1ms.
The response rate indicated by GtG indicates the maximum rate at which a pixel can transition from one shade of gray to the second under certain test conditions using the highest acceleration setting. So always treat these numbers with qualifications.
For example, a TN panel with a given 1ms response rate (GtG) typically has a normal response time
5 ms. To get 1ms you need to apply overdrive. The middle IPS panel will have a normal response time
9ms whereas VA panels typically have response times over 12ms.
Due to their responsiveness, TN displays are popular with competitive first-person shooter gamers, despite their poor color quality and viewing angles. VA panels have the worst response times, but they have the highest contrast ratio of THESE three panel technologies.
This high contrast ratio allows them to create very deep blacks that take longer for pixels to change. Consequently, you get visible blur and ghosting in fast-changing scenes, especially when dark pixels are involved.
While the amount of ghosting on VA panels is too high for competitive gamers, this is acceptable for general gaming as you get exceptional picture quality in return for a reasonable price. IPS panels offer a good balance between the two technologies, but are more expensive.
What is Overdrive on the monitor and how to turn it on and off?
Increasing the response time allows for faster monitor response (pixel transition time) to reduce displacement / ghosting of fast moving objects. Overloading too much, depending on the refresh rate, may cause pixel jitter or reverse ghosting.
You will find your monitor’s acceleration settings in its On Screen Display (OSD), usually under one of the following names: Overdrive, Response Time, TraceFree, or something similar.

To explain what is response time overdrive on a monitor, we will first look at response speed.
You can visit our article “What Does Monitor Response Time Mean?” See article for a more detailed explanation, but in a nutshell, monitor response speed shows how quickly a pixel can transition from one color to the second.
For example, a 60Hz monitor refreshes the image 60 times per second, so 16.67 milliseconds elapse between two refresh cycles.
If your monitor’s response time is lower than this. this means it takes more than 16.67ms to change a pixel, it will continue to change in the next frame, and this is how you get a visible trail of moving objects on the screen.
For a 144Hz monitor, the refresh cycle is 6.94ms, so the response time should be faster, and so on.
This is where Response Time Acceleration, also called RTC (Response Time Compensation), comes into play to make pixels move faster from one color to the second.
MPRT or GtG response speed?
You will also notice that some monitor manufacturers include the 1ms MPRT (Moving Image Response Time) specification as well. This is not the same as the response time of GtG. Instead, the MPRT indicates that the monitor has motion blur reduction technology that, through backlight strobing, reduces perceived ghosting.
The problem occurs when the monitor manufacturer claims the display’s MPRT speed is 1ms, but does not show the GtG response time, misleading potential users that the monitor has a 1ms response speed, when in fact, the GtG response time can be 4-5 ms.
Motion Blur Reduction provides CRT-like motion clarity, but it also has its drawbacks: It decreases the maximum brightness of the monitor when it is active and causes screen flickering. it also cannot run concurrently with VRR (Variable Refresh Rate) technologies such as FreeSync. and G-SYNC on most monitors.
Certain gaming monitors can use VRR and MBR at the same time, such as the ASUS VG279QM display with exclusive ASUS ELMB-Sync technology.
Overload and variable refresh rate
When using FreeSync / G-SYNC, which synchronizes the monitor refresh rate with the GPU frame rate to eliminate screen tearing and stuttering, there are some additional things to keep in mind regarding overload.
Gaming monitors with built-in G-SYNC have variable overload, which allows them to change overload settings to match the refresh rate for optimal performance at any frame / refresh rate.
On the other hand, FreeSync monitors do not have this capability. So, for example, if you are running at 144fps with high congestion and your frame rate drops to
60 FPS, the overload will be too strong for 60 Hz / frames per second and therefore will result in overshoot. Fortunately, this does not happen often.
Some FreeSync models, such as the Nixeus EDG27, have an Adaptive Overdrive function that automatically changes the overdrive preset to match the refresh rate. While not as efficient as G-SYNC variable overdrive, it prevents ghosting and overshoot in certain scenarios.
On the other hand, some FreeSync monitors cannot even run FreeSync and the most powerful overload option at the same time.
In this case, we recommend disabling FreeSync and using High Overdrive at a higher frame rate, or using Medium Overdrive and FreeSync at a lower frame rate. It will also depend on your preference, whether you are more sensitive to screen tearing or ghosting.
