How to turn off the monitor on a laptop, and why you need it?
Some laptop users prefer to work behind large screens by connecting an external monitor to the device. In some cases, such a screen may be needed if the matrix is out of order (so as not to spend money on its replacement).
It is also important to know that the display of a mobile computer is a significant drain on the battery. If you’re just using your device to listen to music, you can turn off the display to extend battery life. Let’s figure out how to turn off the monitor on a laptop.
Save battery power
If you turn on loud music on your laptop and move away from it, then the display does not need to drain the battery power. Using a combination of the Fn key and the corresponding screen button on a laptop, you can dim the monitor, thereby increasing the duration of the battery-free operation. Typically, the display key is in the top row of F1-F12 auxiliary buttons.
By the way, using a combination of buttons, you can increase and decrease the volume, brightness and even flip the laptop screen, that is, the image on it. The latter is used more often on personal computers than on portable devices.
You can also configure the display to turn off on the laptop in the power options. After a certain time interval you have set, the operating system can independently turn off the monitor on the laptop, and send it to sleep mode, if necessary.
How to deactivate the display
There are several ways to turn off your laptop monitor:
- Using the keyboard shortcut.
- By adjusting the power settings to deactivate the display after a specified period of time.
- By physically disconnecting the display from the laptop.
- Closing or closing the lid of the laptop.
- By setting the display mode in the display options.
The first two methods will work for you if you want to conserve battery power on your laptop. The other three methods are effective when connecting an external display to the device. Let’s take a closer look at how to turn off the monitor on a laptop using a keyboard shortcut and other methods.
Turn off the screen of the mobile PC when using an additional device
If you are going to use an external monitor of a larger size and resolution, and the laptop display only distracts you, then you can:
- In the screen options, set the display to only the external display.
- Cover the laptop cover or close it completely, and then the screen will turn off. True, in this case, the keyboard and touchpad of the laptop will not be available to you and you will have to connect additional manipulators.
If you have damaged or broken the matrix of a laptop and now use only an external display, then experts advise to disconnect the matrix cable from the motherboard. If you do not know how to disconnect a laptop monitor physically, how to disassemble it, then we do not advise you to try to do it yourself. Contact a specialized service center. A faulty matrix can lead to failure of the entire laptop motherboard on power supply.
How to properly set up your monitor for comfortable work
So that long-term work at the computer is not a burden, you need to correctly configure the monitor. The most significant parameters affecting the eyes are: brightness, contrast and screen refresh rate. Also consider the correct position of the monitor relative to the eyes and the source of natural light in the room.
Now the activities of many people are directly related to working at a computer. Systematic pastime at the PC or laptop screen negatively affects the health of the organs of vision. By the evening, people with a sedentary lifestyle often experience fatigue, redness, and irritation of the eyes. Many people think that the problem is the wrong distance from the monitor, but this is not the case. The comfort of using technology is influenced by a number of specific screen parameters that must be pre-configured before starting operation.
Choosing and setting up an LCD monitor
Initially, you need to figure out what types of monitors are, since their setting directly depends on this. Truly “harmful” displays have not been produced for a long time, so it can be argued that all modern models on the market are safe for the eyes if the operating rules are followed.
Previously, CRT monitors were actively used, the functioning of which was based on the use of a cathode-ray tube. They damaged the organs of vision quite badly and consumed a lot of energy. They have been replaced by new LCD (liquid crystal) LCD screens that are gentle on our eyes. Depending on the matrix used, they are divided into three categories: TN, IPS and MVA / VA.
The most affordable option is the TN screen, which provides a rather poor viewing angle. If you look at it from the side, the colors of the picture are greatly distorted, which contributes to the rapid fatigue of the organs of vision. Correct positioning of the monitor in relation to the eyes is extremely important in this case. Sitting to such a display should be clearly opposite, otherwise it will be difficult to distinguish a picture or text.
This type of matrix is the highest quality and safest for the eyes to date. It provides a good viewing angle and color saturation. The disadvantage of such a screen is its high cost. As a rule, IPS-matrix is found in laptop monitors located in the middle and high price segments.
The best option in terms of price-quality ratio is the MVA / VA matrix. It is somewhat inferior to IPS in terms of color saturation, but it is almost impossible to notice it with the naked eye. Such monitors provide a good viewing angle, but at the same time they are an order of magnitude cheaper than IPS. This is a good choice for those who spend a long time at the computer.
Setting up the monitor: basic parameters
Discomfort during prolonged work at the computer is often associated with incorrect screen settings. This can be easily fixed by making certain adjustments to them. We advise you to familiarize yourself with how to set the screen parameters so that your eyes are less tired during the day.
The most common parameters that affect the human visual system when working with a laptop or PC are: screen resolution, as well as its contrast, brightness and image refresh rate. Those who care about eye health are advised to pay attention to these characteristics.
Which screen resolution to choose?
Experts say that the optimal screen resolution is “native”, which is often automatically set by the factory settings. In this case, the picture will be the clearest, which will reduce the load on the organs of vision. Some users increase or decrease the standard screen resolution to improve the usability of some applications. However, this often leads to the fact that the picture looks blurry.
You need to right-click on the “Desktop”.
Select in the window that appears the item “Screen resolution” (may also be called “Properties” or “Options”, depending on the operating system);
Select the “Screen Resolution” tab and set the “native” resolution, next to which there is a comment “Recommended”.
What screen brightness to set?
As a rule, the brightness of the LCD monitor is selected individually in each case. However, it should be remembered that it is tiring for the organs of vision to work at too high or, conversely, excessively low monitor brightness. The choice of this parameter depends not only on the type of display, but also on the level of natural light in the room. Adjust the brightness to suit your eyes, taking into account the individual characteristics of the visual system. To do this, change the parameter until you begin to comfortably perceive images and text on the screen.
You need to go to the “Control Panel” and select the “Power” tab.
Choose optimal brightness settings (experimentally).
You can also change this setting by simultaneously holding down the Fn button on the keyboard and one of the special keys to increase or decrease the brightness. As a rule, they depict the sun with plus and minus. However, this feature is present on all devices.
What contrast to choose?
The contrast of the monitor also directly affects the comfort of working at the computer. Overly saturated images put an increased strain on the organs of vision. To avoid this, a person needs to choose a contrast parameter that matches the individual characteristics of his visual system.
Go to the Start menu and then to Control Panel.
Find the section “Calibrate monitor colors” and select the desired tab.
Adjust the contrast by choosing the optimal setting for your eyes (experimentally).
What screen refresh rate to set?
The setting of this indicator largely depends on the type of the device itself. For example, old-style monitors (CRTs) require a frequency of at least 85 Hz, otherwise the eyes will be very tired due to the flickering of the image. Working with the liquid crystal display is quite comfortable at 60 Hz. Changing this setting is easy enough.
How to configure (for Windows XP):
Right-click on “Desktop”, select the “Properties” section.
Go to “Options”. “Advanced”. “Monitor”.
Set the desired value in the line “Screen refresh rate”.
What is the optimal distance from the eyes to the monitor?
For comfortable work at the computer, you need not only to adjust the display, but also to maintain the correct distance from the screen to the eyes. It should be at least 50-60 centimeters. If a person’s vision does not allow comfortable working with text at such a distance, it is necessary to enlarge the font or use vision correction tools. This is the optimal distance from the eyes to the monitor, which is not recommended to exceed.
Quite often, the display is placed too low or too high in relation to the organs of vision, which also leads to excessive fatigue. It is necessary that the monitor is at the same level with the eyes. It should also be remembered that a properly organized workplace can significantly increase a person’s efficiency. The computer or laptop should not be located in front of a window. This is uncomfortable, especially if the ambient light is brighter than the display. By adhering to these simple rules, you can reduce the risk of eye fatigue at the end of the day.

Currently, there are only two main types of monitors:
With regard to CRT, this abbreviation stands for “cathode ray tube”.
These monitors are similar to older TVs (almost the same size and weight). They are older, already rarely used, due to their large size, energy consumption and harm to the eyes.
Cathode ray tubes use high voltages, fast charged particles and other technical things that are more harmful to users than more modern LCD displays.
LCD. short for Liquid CrystalDisplay, which translates as liquid crystal display.
LCD monitors are more compact and lighter because they can be nearly flat. Therefore, today they are used almost everywhere.
A picture in LCD monitors is formed from a set of small dots (pixels), each of which can have a specific color. There are no those harmful effects on the user and his eyes that cathode ray tubes had.
Early LCD monitors were slow, unable to reproduce rapidly changing pictures without distortion, and therefore cathode ray displays were competitive for a while. However, technologies do not stand still, and modern LCD monitors are already devoid of the shortcomings of their predecessors.
Today, when buying a monitor, you can see a diverse range of LCD-only displays. Cathode ray tubes are a thing of the past.
4 Matrix type
There are many types of matrices, it is not so easy to understand them. They depend on the matrix manufacturing technology, and due to this they differ from each other in image quality, viewing angle, image change rate and other parameters.
The viewing angle means that somewhere you can see the image from all sides, and somewhere strictly almost at a right angle, so that the “neighbor” cannot see what is displayed on your monitor.
6 Pixel response time
It is also a rather significant indicator. The shorter the response time, the faster the picture will change (pixels will react faster to the signal).
High-quality modern monitors have a response time of 2-9 milliseconds. The figure 9 milliseconds means that the image of each pixel can change more than 100 times per second.
And the figure 2 milliseconds means the ability to change the image of each pixel 500 times in 1 second! Remember that the human eye no longer has time to distinguish the change in the picture with a frequency of more than 24 times per second, and therefore 500 times per second is a very good result.!
The faster the response, the better the moving pictures the monitor can reproduce. Therefore, fans of computer games and fans of watching high-quality films on a monitor screen prefer monitors with a high response time, and are ready to pay extra money for this quality.
Main features of the monitor and what they mean
A computer monitor is a device designed to display visual (graphic, text, video) information.
Also, some monitors have built-in speakers, and can thus reproduce sound, but this feature is not included in the main characteristics of the monitor.
When buying or assembling a personal computer (PC) from separate parts, be sure to pay attention to the characteristics of the monitor, which we will consider below.
Previously, the monitor was called a display, now this name is rarely used.
1 Diagonal length and aspect ratio of the monitor
The diagonal is measured in inches. 1 inch equals 2.54 centimeters. Previously, the measure (“standard”) of an inch was the width of the thumb on the hand of an adult man. An inch in the designation of the diagonal of the monitor is represented by the quotation mark “- in the form of a double dash. In English inch. inch, abbreviated in.
Most often, you can find models of monitors with a diagonal of 15 “, 17”, 19 “, as well as 21”, 23 “and 27”. The latter option (27 ”) is more suitable for professional designers, photo editors, video editors, etc. Of course, you can use it for ordinary users, if there is an opportunity and desire to have a large monitor.
Monitors may have the same size in inches, but their proportions will differ (Fig. 1).
As for the proportions (the ratio of the length and width of the sides of the monitor), the most common are three formats.
These numbers mean the following. 16: 9. this means that the width of the monitor (horizontal) is 16 conventional units, and the height of the monitor (vertical) is 9 of the same conventional units. precisely, the width of the monitor is 16 times greater than its height, that is, 1.78 times.
And, for example, a ratio of 4: 3 means that the width is greater than the height by only 4 divided by 3 times, that is, 1.33 times.
Monitors with an aspect ratio of 16: 9 and 16:10 are widescreen. They are good for watching widescreen and widescreen video films. It is convenient to open several windows on them at the same time.
Monitors with an aspect ratio of 4: 3 are convenient for those who work with text editors, with graphic files, etc., but for someone they are more familiar.
Monitors with an aspect ratio of 4: 3 are often more convenient for work, and 16: 9 for entertainment. Nowadays, widescreen monitors are also more commonly used for work, simply because they are more common.
Widescreen monitors are convenient for those who like to work with several windows at once. Such users often use PC configurations with 2 (Fig. 2) or even 3 monitors at the same time.
The diagonal length and aspect ratio of the monitor is what users pay attention to first of all, but the main characteristics of the monitor, of course, do not end there.
At what height should the TV be hung 50 inches. At what height to hang the TV in the living room: useful recommendations
To determine at what height from the floor to hang the TV in the hall, you should sit comfortably and look directly at the wall. The head should not be thrown back, so as not to create a load on the cervical spine. The direction of the eyes will point to the point that should be the middle of the screen.
Important! Opposite the eyes of a person, the center of the TV screen or its upper third must be located.
The optimal distance to the TV from the floor for the living room is 1.4-1.6 m. The height of upholstered furniture and the average height of family members are also taken into account. With a standard sofa height, the optimal screen level for children and adults will be different, so the average TV height is determined.
The TV in the living room is hung at a height corresponding to the level of the eyes of a sitting person
If you plan to watch TV from the couch, you can position it just below the recommended level. If the hall is combined with the dining room, and the viewing of broadcasts is often carried out in a sitting position at the table, the unit can be hung slightly higher.
Helpful advice! The larger the diagonal of the TV, the lower it should be placed in relation to the floor.
Many people install the TV in special furniture niches. However, this decision is not always correct. This also takes into account the size of the screen and the height of the sofa from the floor. Imbalance may occur, causing inconvenience while watching.
To mount the TV in the living room, it is better to give preference to a universal bracket, thanks to which you can adjust the position of the screen both vertically and horizontally.
Before deciding at what height to hang the TV in the bedroom, you first need to decide on the place where it will be located. The choice of the right place will depend on both the viewing comfort and the height at which the device itself will hang.
To determine the location, you need to lie on a sofa or bed in the bedroom in a comfortable and familiar position for you. Now you need to determine on which wall the TV should be mounted so that it is as convenient and comfortable to watch it as possible.
Experienced experts say that the optimal location is a point drawn in a straight line from the center of the bed to the wall, and the height of this point will be adjusted later. It is with this arrangement that the TV will be clearly visible to all people who are located in the bedroom, and when viewing it there will be no inconvenience.
Use a Laptop as a Monitor. How to Use Your Laptop as a Second Monitor
If the device is to be hung in a single room or nursery, it must be positioned diagonally from the center of the bed. In this case, even when turning, there will be no discomfort when viewing, and the screen will be clearly visible from any position.
When the potential location of the TV has already been selected, you can directly start calculating the height at which it will need to be fixed.
At what height should the TV be hung 65 inches. In terms of convenience
When we watch TV, we must consider the following:
- the posture in this case is usually relaxed, sometimes semi-recumbent. However, throwing your head back or, on the contrary, constantly keeping it tilted or turned, is uncomfortable. the neck becomes numb. That is, the screen should be approximately at the level of the eyes of a person sitting in the usual position;
- the distance to the center of the panel should be approximately equal to twice the diagonal of the screen. Example: you have a 55-inch TV, we convert it to centimeters (that is, we multiply the number by 2.5, see more details here). 140 cm.Multiply by two and get about three meters from the eyes of a seated person to the center of the screen. In some cases, it is impossible to maintain this distance horizontally, then you can place the equipment higher and get the desired distance. but you will have to watch films and programs lying down. For a bedroom, this is a good option.
Sometimes the problem of the height of the TV from the floor is solved according to the principle “where it fits, we will hang it there.” This happens if a niche for an LCD panel is provided in the furniture wall or the shelves and racks are snug in their places, you don’t want to change them. In this case, it is worth checking whether it will be convenient to watch TV: just sit at the planned place and look approximately at the center of the empty space. Convenient, your neck doesn’t feel numb, you don’t have to turn your head? Fine! Inconvenient? This means that something needs to be changed. either a sofa (bed, chair, etc.), or a place for equipment.
So, at eye level of a seated person, there should be approximately the center of the screen. Another option is possible. at this level there should be a point, offset by about a third from the bottom edge of the panel.
This option will be more convenient if the person periodically changes posture, sitting higher or lower. But there is another nuance. it is desirable to be able to change the tilt of the screen.
Let’s try to summarize. at what height to hang the TV on the wall:
- at eye level of a seated person, either the center point of the screen should be located, or located at a height of 1/3 from the bottom of the panel;
- the distance from the floor to this point should be 1 1.3 m. For people with a height of up to 160 cm, we take the lower limit, at 160 180 cm. 1.1 1.15 m, for higher ones. 1.2 1. 3 m. We take into account the height of the sofa!
- if the viewing is from different points of the room, from different poses. sitting, standing, lying down. we choose the arithmetic mean, that is, after all, at the level of a sitting person;
- we take into account the possibility of tilting / rotating the screen.
For different sizes of TVs, recommendations can be summarized in the table.
|Diagonal in inches||Height, cm||Distance from the bottom of the screen to the center, cm||Distance from the floor to the center of the screen (eye level of a seated person), cm||TV height from the floor in the living room (height from the floor), cm||Installation height of the TV on the wall (along the upper edge of the panel), cm|
|19||42||21||100 120||79 99||121 141|
|21||46.5||23||77 97||123 143|
|22||49||25||75 95||125 145|
|24||53||26.5||74 94||126.5 146|
|28||62||31||69 89||131 151|
|32||71||35.5||65 85||135.5 156|
|40||86||43||57 77||143 163|
|43||95||47.5||53 73||147.5 168|
|49||108||54||46 66||154 174|
|fifty||111||55.5||44 64||155.5 176|
|55||122||61||39 59||161 181|
|58||128||64||36 56||164 184|
Taking a closer look, you can understand that if you follow these standards, TVs with a large diagonal will have to be hung almost above the floor, which is risky in terms of the integrity of the equipment. Therefore, an amendment can be introduced. If the minimum distance obtained is less than half a meter, it is worth increasing it to this value.
Important: in the case when the TV is used not only for viewing, but also for working with consoles (Xbox, Playstation, Nintendo) and special devices (active games with motion capture, “augmented reality”), it is necessary to adjust the height.
Here follows the position of the central point to take the average between its placement for a seated and a standing person. Example: children from 120 cm in height and adults with an average height of 170 cm watch TV in normal mode, a child 140 cm in height plays “fights without rules” using an “augmented reality” device. Therefore, the center of the screen should be at a height of approximately 125 cm.
At what distance to hang the TV on the wall in the bedroom. At what height should the TV be hung in the bedroom?
After repairs in the bedroom, many people also update the equipment in this room. After purchasing a TV, many do not know at what height to hang it. Indeed, not only viewing convenience, but also safety will depend on its correct location.
You can choose the optimal height for placing the TV on the wall in one of two ways. The first is based on the usual viewing comfort, and the second is based on medical advice and advice from the manufacturer.
- You can determine the height level where the bracket mounts will be located if you lie in your favorite position on the bed, close your eyes for a second, and then open them sharply and immediately look at the wall. The point at which your gaze rests will be the middle of the television screen. This means that this is where the main bracket will be located. Choosing this option, it should be understood that parameters such as the distance from the bed to the wall and the dimensions of the diagonal of the screen are not taken into account here. So, choosing this method, you cannot be sure of the safety and comfort of your eyes when watching TV, hung in this way.
- The second method is based on mathematical calculations and advice from doctors. The optimal distance between the eyes and a device with a liquid crystal screen is considered to be its diagonal multiplied by three, and for plasma screens this is the product of the diagonal and the number 4.
At what height should the TV be hung 49 inches. Calculation of the minimum distance from the TV screen to the viewer and the height above the floor
To calculate at what height from the floor to hang the TV, experts advise first to determine the distance from the TV to the viewer. To calculate the distance, the formula is used:
k. coefficient depending on the resolution of the TV screen: for HD its value is 2.3, for Full HD resolution. 1.56 and for UHD. 0.7.
For example, a Full HD TV with a screen diagonal of 42 inches was purchased. In order to convert inches to centimeters, you need to multiply by 2.54.
The height of the attachment is calculated based on the distance obtained by drawing a conditional segment parallel to the floor from the viewer’s eyes to the wall on which it is planned to mount the TV. At this point you need to position the center of the screen. And the ray from the obtained horizon, bent upward by 20 °, will show the place where its upper edge should be located.
All calculations are approximate. In addition, it should be borne in mind that these are the minimum distances. In practice, they turn out to be much larger. At what height the TV should be placed on the wall is also influenced by many other factors, such as, for example, the location of the window from which direct sunlight comes from, the height of the places from which it will be watched, the height of the audience, the surrounding furniture and even the style of the interior of the room. However, at the same time, all medical experts advise to strictly adhere to the distance from the viewer to the TV screen and a height of about 135 centimeters to the TV center and at least 75 centimeters to the lower edge of the equipment.
Method Reconnecting the video adapter (video card)
Some users claim that a simple reconnection of the video card through the “Device Manager” system utility helped them solve the problem of not displaying the second monitor.
This is done very simply and now we will show you how to do it:
- Right click on Start and select “Device Manager”.
- You will see a list of equipment that is installed and running on your system. Find the “Video adapters” section.
- Find the name of your video card in the list and right-click on it.
- Select “Disable device”.
- Then right click on the driver from your video card again and select “Enable device”.
- Test your second monitor again.
Perhaps your second monitor was diligently not being detected due to the fact that the driver for your video card starts malfunctioning for some reason. This simple procedure to reactivate the device can often remedy the situation.
Method Disconnecting the computer, monitors, and cables
Ok, in the last method we tried to simply restart the computer with you in order to get rid of the possible “jamb” of Windows 10 / 8.1 / 8. However, it is possible that the problem is not at the software level, but at the hardware level.
Try turning off your computer completely, disconnecting all monitors from it, and disconnecting all cables from them. Also, remember to unplug your two monitors. Wait a couple of three minutes, and then reconnect all equipment.
Perhaps there was some conflict in the connected hardware of your computer and the second monitor refused to be detected by the system. This method helps some users on the network (at least some of them say so). Plus, there is simply no risk when doing, say, this trick. So why not try it.
PC not detecting second monitor: how to fix?
To get the best experience and improve productivity, users use a bunch of two or more monitors. This does not mean that you have to buy another computer or laptop to use two monitors.
If your video card supports multiple connection ports, then you can safely connect multiple monitors to it. Based on this, the number of monitors you can connect to a PC depends on the number of ports on your graphics card.
You can find various ports on a video card such as VGA, DVI, HDMI, and Displayport. These days, HDMI and Displayport are the most popular connection interfaces. VGA and DVI-I (not DVI-D), in turn, are practically not used anymore (connecting a modern video card to a VGA monitor is generally incredibly problematic).
The most common connection interface is HDMI, which gives users access to the highest resolutions available today. Plus, HDMI can also carry the signal from the sound card.
In addition to various connection interfaces for transmitting video signals from a video card to a monitor, there are two different types of video cards: integrated and discrete (PCIe). What is the difference between these two types of video cards??
An integrated graphics card is built into the motherboard, and a PCIe graphics card plugs into a PCIe slot on the PC motherboard. If you play video games, do graphic design or video editing, then we recommend that you use a discrete graphics card, as it is designed for such tasks and is much more productive.
At times, you will need to connect a second monitor to your machine. This procedure is quite simple: we take a cable with the desired connection interface, for example, HDMI, connect one end of it to the connector on the video card, and the other to the connector on the monitor. That’s all.
However, sometimes everything does not go so smoothly, and your computer, for some reason, cannot detect the second monitor. What is the reason behind this trouble? So, there are many reasons: cable problems, incompatible drivers, problems with the user’s computer configuration, etc.
In this article, we’ll look at 10 different methods that we hope can help you with the problem of detecting a connected monitor.
Method Restart the computer
In the Windows operating system (as, indeed, in any other OS), sometimes various bugs and errors appear that prevent its correct operation, and, as a result, prevent the user from using the OS functionality.
Try restarting your machine to fix the possible problem. There is a chance that the problem is on the side of your OS, which stubbornly does not want to detect the connection of another monitor in the available devices. After rebooting, try the above method again.
Method to rollback a driver for a video card to a previous version
Perhaps the problem with detecting the second monitor lies in the driver for the video card that is currently installed on your system. To fix this problem, you can try rolling back your video driver to a previous version. This is done, again, through the Device Manager.
- Go to Device Manager, go to the Video adapters section and find your video card.
- Right-click on it and select “Properties”.
- Go to the “Driver” tab.
- Click on the “Rollback” button.
As soon as the driver rolls back for your computer, try connecting two monitors to it again. If this time everything went fine and you did it, then the matter was definitely in the driver for the video card.
Method Activating Multiple Displays
If you are an Nvidia graphics card user, then you can try enabling the multiple display option in the Nvidia Control Panel.
- Right click on the Desktop and select “Nvidia Control Panel”.
- Go to the “Display” section.
- Click on the subsection “Installing multiple displays”.
- Check the box next to the one connected to your computer.
- Click “Save” and close the Nvidia Control Panel.
Monitor matrix overclocking. theory and practice
I think that most PC users have heard about the fact that you can overclock a processor, video card or RAM. However, few people know about the fact that you can also overclock the monitor, and often the difference from its overclocking is more significant and noticeable than from overclocking other hardware. It is also safer, but more on that below.
Theory To begin with, what is meant by overclocking a monitor matrix? This implies an increase in the refresh rate of the monitor from the standard 60 Hz and by how much it will turn out. 70-75, sometimes 120, and even 150 Hz (!). Why is this needed? To improve the smoothness of the picture. What does it mean that the refresh rate of the monitor is 60 Hz? This means that the picture on the screen changes exactly 60 times per second. In this case, the video card can produce both a lower number of fps and more. If the number of frames issued by the video card is less than the refresh rate, then some frame will be displayed twice (or even three times), which can lead to noticeable delays. If the number of frames issued by the video card is greater than the monitor’s refresh rate, then it will turn out that two or three frames will be displayed on the screen at once, which will lead to artifacts:
The trade-off is the vertical sync setting. What is its essence? It tightly links one frame, prepared by the video card, to one update of the image on the monitor. And here, if your video card consistently produces more frames than the refresh rate of the monitor, then you will get an ideal smooth picture, but your video card will not be 100% loaded at times and will rest. And it is precisely this mode of operation that is often used in the system. for example, when you scroll in the browser, you do not see artifacts, and at the same time the scrolling is smooth.
Raising the refresh rate of the monitor kills two birds with one stone: firstly, now the vertical sync will go at a higher frequency, which means the smoothness will increase even more (I think everyone saw the difference in YouTube videos with 30 and 60 frames? Here also). Secondly, if your video card in games produced more than 60 frames per second, then now the threshold for the appearance of artifacts is pushed back to the new refresh rate, while the information on the screen will be updated more often, which is quite important for dynamic games.
Of course, the question arises. how safe is it? It is much safer than overclocking hardware: if the monitor cannot work at a given frequency, it simply will not turn on. If it works at a given frequency, it means that you will not have any problems. Overheating, as in the case of overclocking a processor or video card, is definitely not in danger.
Practice Now that we have figured out a little theory, you can move on to practice. The first thing you need to know is that any monitor and even laptop matrices are chasing, but there are several limiting factors at once. The first is the connection method: via DVI at a resolution of 1920×1080, you are unlikely to get more than 65 Hz. the reason is the rather low bandwidth of the interface. Through older HDMIs (up to 1.4) at the same resolution, you will most likely be able to get around 75-85 Hz. Well, through the new HDMI (1.4-2.0), Thunderbolt or DisplayPort there are practically no restrictions. you can get 120-165 Hz. Similarly, there is often no limitation for laptop matrices connected directly to the board. The second limiting factor is the matrix itself, or rather its controller. It happens that even with a fast connection, when the frequency increases, some image artifacts appear. alas, there is nothing you can do about it, except how to reduce the frequency to the last stable one.
Now let’s talk about how to overclock. Owners of video cards from Nvidia are lucky here. for them the algorithm is simple: you need to go to the Nvidia control panel, go to the “Change resolution” tab, click on the “Settings” button, in the window that opens, check the box to enable modes that are not supported by the display, and then click on the “Create custom resolution” button, and in the window that opens, we finally get access to change the refresh rate:
The frequency should be raised by 3-5 Hz, then press the “Test” button. If no artifacts appear and there is an image, raise the frequency even higher. As soon as artifacts appear or the image disappears, reduce it to the previous operating frequency, and then raise it by 1 Hz. in general, everything here is exactly the same as with normal overclocking of a video card. After you have found the desired refresh rate, simply save the resulting configuration, and it will appear in user permissions.
As you can see, there is no risk here. if the monitor “does not start up” at the frequency you specified, after 20 seconds the system will roll back the frequency value to the default. Alas, everything is so good only with video cards from Nvidia, with video cards from AMD or Intel everything is worse. there you cannot increase the frequency in the driver settings, however, there is a universal application that will help you do this. it is called Custom Resolution Utility (CRU), download its latest version can be found here.
I will warn you right away. the program’s problem is that it does not have a Test button, as is the case with Nvidia, so the frequencies are applied immediately and irrevocably. So if after setting the frequency you see a black screen, either connecting a second monitor and returning the settings to default will help you, or entering through safe mode and doing the same.
Working with the program is quite simple. you launch it, remove all resolutions from the standard ones and uncheck all the boxes on the left (I will not do this for myself, because I have already overclocked the matrix through the Nvidia settings): Now, under the window with Detailed resolutions, click on the Add button, set Automatic. LCD Reduced and below we change the refresh rate: Here the principle is the same. we increase the frequency by 3-5 Hz, click OK, save everything and reboot. Now we go into the AMD (or Intel) panel and set a new frequency: Here, in general, that’s all. as you can see, there is nothing difficult or dangerous.
Well, the last question remains. since almost all matrices are overclocked, why do not manufacturers do this from the factory? Everything is simple here: there is such a concept as a standard, and for the refresh rate of monitors it has been 60 Hz for a long time. Therefore, manufacturers, even if the matrix is capable of operating at 70-80 Hz, still limit its frequency to the standard 60 Hz. Secondly. often everything depends on the connection method. For example, you can transfer 1080p60 via any interface, even DVI, even Thunderbolt 3. But for 1080p80 you already need a special cable. DVI and old HDMI are no longer suitable. And in order not to create confusion, the manufacturers again limited themselves to 60 hertz.
As for the question, to overclock or not to overclock. it’s up to you and only you. If you managed to increase the frequency from 60 to 65 Hz, then there is no point in such overclocking, you will not see the difference. But when overclocked to 75 and above Hz, the difference becomes clearly visible, so the game is worth the candle here. It should also be borne in mind that after overclocking, the load on the video card will increase during normal operation. after all, it will now have to produce more frames per second, so if you overclock the matrix on a laptop, you should take into account that your battery life will decrease slightly.
