Why the monitor does not work through an adapter

Monitor does not work when connected via HDMI

In principle, the question is clear from the title of the topic, I turn on the monitor via HDMI, it does not show signs of life, everything works fine through vga. I do not understand what the problem is, the monitor supports such a connection, the video card too, help with advice, who came across this, what to do?

It seems to me that the problem here is in the video card, and not in the monitor, and the HDMI cable itself can be checked if you connect it to the TV.

I also connect in the old fashioned way only through the old entrance. I never really trusted these new technologies.

It will take a long time for everyone to switch to this type of connection.

It may be that the cord itself does not work, I would start checking with it, at least. If it is possible to check the cord, proceed. Other reasons remain less rosy, for example, the HDMI input on a video card or monitor could burn out.

In my opinion, this input needs to be activated, this is done either in the monitor settings or in the video card settings. Only then will it begin to work fully. Try to search for a similar item in the settings.

It means that you simply do not have a working input or HDMI cable through which you are trying to connect the monitor. How long is the cable? Generally, the longer the cable, the more problematic it is.

Check the cable and the connector itself on the video card, it may be worth updating the driver. Try connecting another monitor via HDMI to the computer if possible, see the solution to the problem in the settings.

Most likely, the input itself does not work, this is, in principle, logical. Check the contacts, try a different cord to connect. If nothing changes with this, then they have already given good advice above about enabling HDMI.

Well, at least it shows something, because it happens that it does not show anything at all both via HDMI and VGA. In this case, the problem is then more global.

For this reason, I like to connect only standards for everyone using the old reliable proven VGA. How much I used, I never had any problems.

Some Chinese video cards have such a connector, but it does not work, this problem is very common, so this may be your case. Although if the video card is definitely not from some aliexpress, then you need to look for another reason.

This is for sure, and on most new 10th generation video cards and beyond, there is no conventional connector. Therefore, only HDMI is used, as for the fact that it does not work, most likely the problem is in the video card.

I need to check how the monitor works via HDMI, because until now I only connected it via VGA.

How this connection differs from HDMI?

Although according to many experts, HDMI is considered much better and better quality than the same VGA input, but it does not seem to affect the quality of the picture much. And so VGA will be even more stable by an order of magnitude.

The cable worked fine for 3 weeks, then the image disappeared, what could have happened? There is no VGA on the PC, only HDMI and mini HDMI. Thank you.

It seems that the picture is better via HDMI, but to be honest, after connecting, I did not see much difference. In general, it’s up to you to figure it out or not, but in my opinion, using the output that works for you is no worse.

Here it is rightly said, I also think that a standard connection is enough for work or the Internet. You will not notice any difference, in games there may and will be an increase in fps, but insignificant.

This cable simply has more capabilities, it can transmit not only a good picture, but also multichannel sound, for example. Someone like that and really unnecessarily, nevertheless, in some cases, it allows you to get rid of unnecessary wires.

With such advances in technology, USB ports will soon be a thing of the past and will only use HDMI. It is convenient and even more so, if it is of high quality, then what to think at all.

Such moments should be checked immediately, especially if you decide that you will only connect through this port. Although it works more, it is always normal, but there are failures.

Solution to the problem: the HDMI-VGA adapter does not work

As mentioned above, not always connected adapter displays the picture on the screen and works completely correctly. In some cases, the monitor, video card, or the model of the equipment used are simply incompatible with each other or require additional settings. The problem with a non-working adapter is solved in several simple ways. Let’s take a look at them.

Monitor does not work via HDMI vga adapter

monitor, does, work, adapter

Often, users with old monitors are faced with the lack of digital connection interfaces on new video cards. In this case, there is only one solution. the use of special adapters and converters. The correctness of their work directly depends on the models of the video card, monitor and the quality of the device itself. If you are faced with the fact that the purchased equipment does not work, do not be upset, because you can try to fix this problem with several simple methods.

Replacing the adapter with an active converter

Usually, when connecting a computer with a new video card to an old monitor or TV, the power supplied through the cable is not enough. Because of this, simple adapters will not display the image. In addition, they do not allow sound transmission due to the lack of an appropriate connection cable.

Go to BIOS

Sometimes users are faced with literally mystical device behavior. For example, when, when the PC is turned on, information about the start of the system boot appears on the monitor, but after that the image disappears and nothing else happens. In this case, the problem may go deeper, perhaps the whole thing is in Windows. What to do if the computer does not see the monitor in this case?

To do this, you need to boot the system in safe mode and restore the OS using the built-in system restore function. You can also perform a manual factory reset. However, for this you need to have sufficient knowledge and skills.

Video driver settings

In this subsection, 2 problems can be distinguished:

  • your video drivers are not installed / updated at all (there are those that were installed on the system along with Windows);
  • in the video driver settings, the “picture” on the second display is disabled.

First, I recommend opening the control panel of your video driver. As a rule, it is enough to use the tray icon (next to the clock), see the screenshot below.

The second option is to open the Windows control panel, convert the display to large icons, and find a link to the video driver control panel (Intel graphics setting, as in my example below).

Control Panel. Large Icons / Clickable

If you do not have such configuration links, most likely you do not have the drivers installed. Try to go to the device manager (to do this, press WinR. and use the devmgmt.msc command). and look at the “Display Adapters” and “Other Devices” tabs. If you have a driver installed on your video card. you should see the name of your adapter, if not. something like “Video controller (VGA compatible)”, see the example below.

Note that another situation is not uncommon: the driver can be installed, but the control panel is absent. In this case, you also need to reinstall (update) the video driver.

In the driver control panel, as a rule, you need to open the “Display / multiple displays” section (example for IntelHD video cards) and click the “Find” button (if the PC does not see the second display). In the same section, you can select the display mode, specify the number of active screens, and other parameters.

Intel Control Panel. Multiple Display / Clickable

If we touch on AMD / nV video cards “Display / installation of multiple displays” (see the screen below). There you can also specify which displays will be used, check their configuration, set parameters, etc.

Checking the cables

If the wires are damaged, it can also affect the operation of the device. In this case, it does not matter at all whether the computer does not see the monitor via HDMI, DVI or VGA. Any of these wires can come off at the most unexpected moment. Most often this happens when the cable is not screwed into the back of the screen and PC, but simply inserted.

If you are using a dedicated video card, then you need to make sure that the screen is connected to it, and not to the usual connector on the motherboard. As a rule, the system automatically turns off the standard graphics and uses the connected device. If this did not happen, then you need to turn off the image feed through the “mom” manually.

CPU

Sometimes all the components of the system work properly, and there are no problems in the monitor itself either. This situation confuses any user. It is not surprising if the PC emits a distinctive sound and the monitor works great with other devices. In this case, the problem may be with the processor. If it fails, then the computer will make a characteristic sound, but in fact the system will not start loading. This is due to the fact that the coolers are spinning, but nothing else happens. At the same time, even the motherboard can produce a number of characteristic sounds. However, nothing can work with a burnt-out processor.

Processor malfunction

One of the possible malfunctions may be the failure of the processor. When this happens, there is no image on the monitor, but the motherboard should emit several beeps when the computer is turned on, which indicate a problem with the processor.

RAM is defective

Another reason is RAM. To check its operability, it is enough to remove the memory module and insert it into the adjacent slot. The ideal option would be to install a known good module.

How can you try to fix the situation

If you can’t get a picture from a computer on a second monitor via HDMI, pay attention to other connectors: DVI, Display Port, USB Type-C, VGA. As a rule, most monitors (like PCs) have several interfaces for connecting.

You can learn more about the monitor / TV connection interfaces from this article: https://ocomp.info/razemyi-monitorov-dvi-display-port.html

The difficulty, perhaps, can arise with laptops: many models have only one interface, HDMI (say). However, on new laptop models, in addition to HDMI, there is a USB Type-C port. You can purchase a cable (adapter, adapter) for VGA, DVI, Display Port (and connect almost any monitor).

There are a variety of adapters (adapters) to USB Type-C for VGA, DVI, Display Port

Perhaps one of my previous articles about connecting a second monitor to a laptop will be useful to you. https://ocomp.info/kak-podklyuchit-monitor-k-noutbuku.html

For a significant number of people, life is simply impossible without a computer. Therefore, it is very unpleasant when there are problems with your favorite device. For example, some users are faced with the fact that the computer cannot see the monitor. This can happen both with a standard device and when connecting an additional device.

There are a great many reasons for this trouble. Sometimes users simply forget to connect a monitor. However, more often than not, the problem turns out to be more global. As a rule, when the computer does not see the monitor and there is no signal, the reason may lie in the hardware of the device. For example, this is a damaged cable, insufficient RAM, a video card error, or even the motherboard itself. Slightly less often, problems are associated with the operation of the system itself. Let’s try to figure out why the computer does not see the monitor and how to solve this problem.

Projection settings. Detection

In general, when you connect a second monitor to a computer / laptop, it automatically transmits the image to both screens (to its own and the second connected one). In this case, usually, a window with a choice of projection will appear on your desktop (i.e. how to work with an image on 2 screens):

  • show the image only on the PC screen;
  • repeat the image on both screens (default option);
  • expand (ie you will have 1 desktop divided into 2 monitors. Convenient when you need a “large” desktop);
  • only the second screen (the image on the laptop / PC screen will be “blanked out”).

The problem may be that instead of the default option (i.e. show the image on both screens), you may have an option set to show only on the PC screen. In this case, the image will not be transmitted to the connected second monitor.!

To “manually” call this projection panel. press the WinP button combination (and then change the “on both screens” projection option). If you have a laptop, pay attention to the function keys: there are also additional keys among them. options.

I also recommend opening the Windows settings, the “System / Display” section and clicking on the “Detect” button (in some cases, especially if your display is old. this function will help you detect and use it).

Connecting laptop / computer to TV via HDMI does not work

and more users are starting to use a computer or laptop as a signal source. Problems can arise here as well. If you cannot connect the laptop / PC to the TV, then check in the system settings if HDMI is used as the video and audio signal output. If you still do not understand why HDMI does not work in the computer-TV connection, then try the following:

  • Connect the TV and computer with a cable, and then restart the last.
  • Try turning on or restarting your laptop or computer and then turning on the TV.
  • If this did not work, then turn on the computer, then turn on the TV, and after that. connect them with an HDMI cable.
  • If this does not help, then transmit the video signal from the computer to the TV through the VGA output (if the TV has such an input).

HDMI Troubleshooting Tips

  • Check if the cable is connected correctly: If HDMI does not work, then, first of all, see if the connectors on the ends of the cable have come off the pins in the jacks. In most systems, the cable is not very tight and can easily come off. If this turns into an ongoing problem, consider how to secure the HDMI cable.
  • Try turning on the devices in a different sequence: In other words, if you always turn on the TV first and then turn on the Blu-ray disc player (or other signal source), then, when faced with a problem, try to change your habit and turn on the player first. If your home theater has three or more components, then try different options for the sequence of their inclusion. After finding the sequence that led to a positive result, remember it.
  • If your devices have multiple HDMI inputs or outputs, test each one in a different power-up sequence.
  • Check the resolution settings of the video signal on the source: It is best to set the automatic resolution in the settings of the source device. You can also try changing the resolution on your TV and find one that works.
  • Use the exclusion method: If the previous steps still did not help you figure out why HDMI is not working, then in complex systems (for example, the signal from the player is sent to the home theater and then to the TV), exclude those components that you can do without (in the example given. home theater). Connect your Blu-ray disc player directly to your TV. If everything worked, then the excluded component is the culprit. In the example shown, you can transfer the video signal directly (via HDMI), and the sound can be fed to the home theater with a separate cable. This is not the most elegant solution, but it can be used as a temporary measure until the problem with the home theater is fixed.
  • If none of the above techniques gave the expected effect, and you still do not understand why HDMI does not work, then update the firmware of all devices (player, receiver, home theater and even TV).
  • You can also read thematic forums on the Internet. Someone may have faced a similar problem before and a solution has been found.

Why HDMI does not work: an algorithm for solving the problem

Most home video systems today, including high-definition plasma TVs, video projectors, Blu-ray players, network media players, satellite receivers, and the like, use HDMI for signal transmission. This protocol was developed to facilitate the transmission of high-quality video and sound.

In addition, it implements HDCP copy protection. Components connected via HDMI must be able to recognize each other and exchange service information. The latter is often referred to as the “HDMI handshake”. If you are trying to understand why HDMI is not working, then it is quite possible that one of the devices cannot recognize HDCP overhead information sent to it by another component. As a result, we see nothing on the TV screen.

When faced with the problem of connecting devices via HDMI, I recommend checking a few simple things that, with a high degree of probability, will help you.

Troubleshooting HDMI-DVI or DVI-HDMI connection problems

Difficulties often arise when connecting two devices, one of which has an HDMI port, and the other has a DVI port. In this case, an HDMI-DVI adapter cable or a separate HDMI-DVI adapter is used, located at one of the ends of the DVI or HDMI cable. In addition, a device with a DVI port must be HDCP compliant. This is a prerequisite for pairing two devices.

It should also be remembered that while HDMI can carry audio and video, then DVI is for video only. This means that you will have to use an additional cable to transmit sound.

  • In most cases, video is transmitted through the HDMI-DVI link without problems. If the video transmission does not work, then the most likely cause is over
    walker. If you try several models, then the question may be resolved by itself.
  • However, if your TV is old enough, its DVI port may not support HDCP. In this situation, try downloading and installing the latest firmware. It is also worth trying to transmit the signal from this source to another receiver. Possibly the problem is with the player, laptop, or receiver.

Remarks

In the overwhelming majority of cases, the problem with signal transmission is associated with an insufficiently reliable connection between the HDMI cable pins and the jack. But the reason may be more complex. If you are faced with a problem with the HDMI connection, then do not panic, but carefully read the above recommendations, and you should have everything working.

Well, if this does not help, then contact the technical support service for the purchased devices for help. If this did not solve the problem, then you are faced with a warranty case. contact the seller.

And yet, if you are used to “looking to the future”, then immediately purchase an HDMI cable with a bandwidth of 10.2 Gbps. It won’t be a big deal today, but when TVs and 4K sources fall in price, this cable will come in handy.

TV settings

When the TV does not see the laptop via HDMI immediately after connecting the equipment, it is most likely that the wrong source is selected on the TV itself.

If there is no signal from the computer, then on the TV remote you should find the “input”, “source” or “Imput” button, it may be written “HDMI” on the TV from LG. Go into the window that opens and there, in the list of active inputs, select the one you need. Confirm the action by clicking on “OK”.

If the equipment still does not connect after the operations performed, we carry out the diagnostics further.

This malicious interface

If the signal is the same, then why does connecting a monitor via HDMI often cause so many problems, but everything is fine via DVI? The reason, paradoxically, is not technical differences, but marketing positioning! The fact is, initially, HDMI was not planned to be used to connect a computer with monitors. And indeed, why? There is an equivalent DVI in terms of capabilities! But TVs, media players, game consoles and camcorders quickly acquired this convenient and compact interface. We also received HDMI video cards and monitors. the first for connecting to a TV, the second for working with game consoles and other household appliances. And, as a natural result, recently HDMI has completely replaced DVI on many monitor models and even some video cards are equipped with two HDMI ports.

READ  No signal on the monitor when the computer is turned on

And here the problems began to arise. The fact is that the developers of video cards still assume that the user will primarily connect the TV to the HDMI interface of the video card. Similarly, monitor developers believe that a consumer multimedia device is most likely connected to the HDMI port of the monitor, and not a computer. But despite the fact that HDMI is HDMI everywhere, household and computer equipment work with video content in slightly different ways. Let’s understand these differences.

Why the monitor does not work via HDMI

Cable check

If the TV connected to the PC suddenly stopped working, and until that moment everything was set up properly, it means that the cable came off or was interrupted. The first option is more common, since you can hook the adapter just by walking by. But the second one is less common, since the optimal length of the HDMI cable is not so long as to lie on the floor and fall under someone’s heavy foot.

In any case, if there is no picture, first of all check if the connectors are fully inserted into both devices. And if there are any foreign objects on the adapter itself. You can also try to put in a different cable to make sure that this error is absent. Also read why the TV won’t connect Wi-Fi.

Twins DVI and HDMI

Initially, HDMI was developed on the basis of DVI, and the transmitted signal itself has not changed at all. Essentially, HDMI was conceived as a DVI analog for consumer electronics. The connector has undergone modifications (it has become more compact), the ability to transmit multichannel digital audio has been added, the ability to play protected content (HDCP, from the English High-bandwidth Digital Content Protection) has been added, and the analog transmission function has been removed. signal. In particular, therefore, there are simple and inexpensive HDMI-DVI-D adapters.

Later, when the basic capabilities of DVI / HDMI were not enough, the interfaces were modernized. DVI received six additional pins for signal transmission in a higher mode than 1920×1200 pixels with a refresh rate of 60 Hz (DVI-D Dual Link).

HDMI went a different way. in version 1.3 the clock frequency was raised, due to which the interface bandwidth was increased and support for high modes appeared. In addition, version 1.4 adds support for stereo modes (3D video). One way or another, most monitors with a diagonal of less than 30 “operate in 1920×1080 @ 60 Hz mode, which means that the capabilities of regular DVI and HDMI 1.2 are enough.

Color dialects

The problem with incorrect display of colors via HDMI is much more complicated. The reason for all the difficulties lies in the fact that there are several models for representing a color image, and all of them were originally developed for analog interfaces. The most common model, RGB, is still used in the analog VGA interface, as well as in digital DVI and HDMI. According to her, the picture is divided into three color components. red, green and blue. The intensity of the component is set by one 8-bit number per pixel, and, accordingly, can vary in the range from 0 to 255. The maximum black color in this model will be encoded as 0, 0, 0, the brightest white. 255, 255, 255, bright blue 0, 0, 255, etc. In total, this gives 255x255x255 = 16,777,216 combinations (color gradations).

Initially, due to the limitations of the analog signal, not the entire range of values ​​was used, but only from 16 to 235, i.e. black is 16, 16, 16, white. 235, 235, 235. Therefore, historically, household appliances use just such a range, the so-called limited RGB. Note that one more color-difference model YUV (YCbCr) is still used, but at the moment both monitors and TVs use exactly RGB, and when receiving YUV they are forced to convert the signal.

Computer technology initially focused on the full RGB range. But, as we remember, HDMI was originally developed for home appliances. Accordingly, video cards expecting a TV to be connected to their HDMI port turn on limited RGB by default, while a monitor, depending on the model, can expect both limited and full RGB over the HDMI port.

There are four different options available:

Note that users of video cards based on NVIDIA chips most often face problems. This is because the NVIDIA driver was originally written to use limited RGB for HDMI output, while most monitors expect full range. over, there are no RGB range settings in the driver, and you will have to either go deeper into the Windows registry, or switch the range in the monitor, if, of course, your model has this option. However, you can access the registry not with your hands, but with the help of specialized utilities, for example, Nvidia RGB Full / limited range toggler (http://blog.metaclassofnil.com/?p=83) will allow you to switch the range on an NVIDIA card in one click If you have a video card from AMD, and as a monitor you use a TV that expects a limited range, then you can easily switch the range in the driver.

Some tips

The last thing that could be the reason that the TV does not receive an image via HDMI is a broken port. For diagnostics, check the functionality using other adapters. If the devices become visible, the error lay precisely in this.

Solution to the problem: the HDMI-VGA adapter does not work

As mentioned above, not always connected adapter displays the picture on the screen and works completely correctly. In some cases, the monitor, video card, or the model of the equipment used are simply incompatible with each other or require additional settings. The problem with a non-working adapter is solved in several simple ways. Let’s take a look at them.
