The new video card does not display the image on the monitor

Monitor check

Sometimes the problem is with the monitor itself. Check if the power is connected, if it is on and the cable is connected to the video card. Try replacing the cable if possible. In addition, you should carefully make sure that the HDMI, VGA, DVI or Display Port wire is connected correctly.

Faulty image transmission cable

The second component in the chain of transferring a picture from a computer to a monitor is a cable. Problems with its integrity lead to both the complete cessation of image transmission and the appearance of artifacts on the monitor screen. Fault options:

  • The cord was pulled out of the socket. You should check the reliability of the connection, and also make sure that the fastening screws are tightened (relevant for the DVI and VGA connectors). It will not be superfluous to pull the plug out of the seat and perform a visual inspection: there should be no dirt, bent or burnt contacts on it.

The cable is bent, contact is lost. The picture can disappear completely, disappear, or one color predominates. It is also possible that the color temperature changes to cold or hot tones.

Diagnostics is simple. replace the cable. Usually, the monitor comes with an HDMI and VGA cable, so connecting with a spare will not be a problem.

On my PC, the system is fully loaded, there is a sound of inclusion, but there is no image, the monitor is fully working

The same thing works for me, but there is no image what to do?

The power supply unit does not match the one indicated on the video card and the current is not enough. For example, the same video card fully operates with a 550W power supply, and does not display an image with a 350W power supply. The video card indicates that the power of the power supply must be at least 400 watts

Hello Egor. I recommend that you use a power supply of at least 500 watts for this video card, since you need to take into account other connected components as well. In addition, during peak loads on the graphics adapter, the power consumption increases.

see the consumption of the PC on the bequeit website, just for the beginning, find out what you have and what is connected

“The new video card Palit GeForce GTX 1060 JETSTREAM, a couple of months, but there was a problem. after a few starts the monitor does not turn on. The card itself is backlit, although it is disabled using the Thunder Master program. Monitor connected to DVI-D, TV monitor to HDMI, none of them respond. black screen. You have to restart the computer, only after that it turns on and the backlight turns off, as it was installed. I may be wrong, but when the monitor was connected to HDMI, there were no such problems, but even if you do not use the DVI-D connector, this is not normal. ” I wrote this in Support Palit.

I was advised: “According to the description, the reason may be in other components of the system, in particular, in the power supply, check the video card with a different power supply unit and, if possible, with a different configuration.”
but I do not have such an opportunity, only carry it under warranty and hope for a miracle.

can problems in the DVI-D adapter? but shouldn’t the SIM card continue to work, and this: the backlight turns off, as set by the Thunder Master program and there is simply no image on the monitor?
I have a new power supply (like everything else) 550 watts.
I bought a SIM card in a month, without it the computer worked stably by displaying an image through the m. board.

I can not tell you exactly how many watts this power supply unit produces in reality. Most likely, the backlight of the video card should be turned off only after the start of the operating system. Do you have the opportunity to put another video card weaker and check the performance of the PC through it? In addition, I can recommend that you reinstall the graphic adapter driver or use an older version of it.

If this does not help, connect the monitor through the motherboard and check if the graphics adapter works. In extreme cases, you will have to contact the service center, change under warranty.

I have the same story, the video card turns on every other time, and this was periodically from the very beginning of the purchase,
most likely this is the incompatibility of the motherboard of the same manufacturer MSI (with NVIDIA chips) and the ATI video card,
cut off unnecessary energy consumers, does not help. The board is already 10 years old, I use this computer just as a storage. Previously turned on by repeatedly opening-closing DVD, stopped helping.
Now, just a comedy, I first warm up the computer like a car before driving. Then I turn it off for 5 minutes (I let it cool down). And so, I turn it on again, and the computer, just a cucumber, starts working as if nothing had happened!

From time to time, the image on the monitor disappears. How to figure out what the problem is?

Some computer users are faced with a situation where after pressing the power button, an image is not displayed on the monitor, or it has obvious artifacts (ripples, stripes, color change). There are many reasons for this problem, both among the hardware of the devices and the software environment. In the article below, we will name the possible sources of the problem, give recommendations for diagnostics and elimination.

Checking the power supply

In the case of an insufficiently powerful power supply, the computer will not work correctly, this will also affect the image output. Pay attention to special services that allow you to calculate the required power of the PSU in relation to the installed components. If your model does not meet the requirements, then it must be replaced. Read more about the services for calculating the power of the power supply and its choice in our article.

If none of the above methods helped you, then most likely the problem lies in a broken video card. In this case, it is better to contact the service center for diagnostics, and if necessary, choose a new graphics adapter suitable for the motherboard.

Thank the author, share the article on social networks.

Broken monitor

The failure of the screen can be detected by indirect signs: after turning on the power, the coolers start working, after a while the system emits a single “peak”, which indicates that there are no errors in the components, then the sound of Windows loading is heard.

If the matrix was subjected to physical impact (falling, impact), then vertical stripes may appear on the computer monitor. It will not work to fix such damage on your own, and the service is unlikely to help. The cost of the repair will be too high, and there is no guarantee of success.

To diagnose a screen malfunction, an alternative monitor or TV should be connected to the computer.

If the user is dealing with a laptop, the cable may be disconnected. You can also verify this by transmitting a signal to an external monitor. If, on the contrary, an external screen was used before, but now it was turned off, the computer may think that it is still active. To switch the signal, you can use a special key on the keyboard (row F1-F12).

Reinstalling components

When assembling the computer, some parts might not fully fit into their connectors or the connection was made incorrectly. Remove the side panel of the case and carefully examine everything inside. Check the wire connections with the instructions that came with the computer or motherboard. Pay special attention to the video card, whether it is well installed and whether additional power is connected, if any. In addition, pay attention to the processor, whether it is installed correctly and securely.

Determining the cause of the breakdown by the BIOS signal code

Each manufacturer uses a different combination of short and long signals, so we strongly recommend our article on this topic about Honor to be familiar with all the signals of their BIOS manufacturer. Based on the results obtained, try to solve the problem yourself or take the computer to a service center.

PC health check

In rare cases, the computer does not completely go through the power-on cycle, but freezes at a certain point, which may make it seem that the problem is in the video card. For example, the most common problem is crashing when resuming from sleep or standby mode. To check this, you need to hold down the power button for a few seconds, wait until the computer turns off completely, and then turn it on again. If the problem persists, then go to the next method.

Why the video card does not display the image on the monitor

There are a number of reasons for the appearance of this problem, each of them has different ways of solving it in complexity, so we will move from the simplest to the most complex, so as not to perform unnecessary actions in the event of a minor problem. Let’s get down to analyzing all the ways.

The article discusses a specific situation when the processor starts up in a standard way: all indicators are on, all fans are on, a characteristic post-signal has passed, after which the operating system starts up, but the monitor does not display any image. The check must be carried out in a specific sequence, since there are more common causes of problems and vice versa.

  • First of all, you need to check if the cables are connected correctly. Naturally, first it is worth checking the cable that supplies electrical energy for the display to function. If it is not damaged and connected correctly, the socket to which it is connected is also working and there are no defects in the connector on the monitor (if the cable is not soldered), then you should go to the video cable. Most often, a VGA cable is used to transfer a video signal, and recently the HDMI standard has become popular, however, connectors for it are available only in the newest models of monitors. The stages of checking this component are not much different from the previous one. If the cause of the problem was found, and it was in one of the cables, then it can be solved quite simply. replace or repair the defective cord.
  • Since the stage of presenting the image to the screen occurs even when the BIOS starts up, the problem may well be hidden there. Naturally, in the absence of an image, it will be problematic to change any settings, but you can reset them. To do this, you need to open the system unit and pull out the battery located on the motherboard. Many do not even know about its existence, but in fact such a “crumb” stores the most important BIOS settings, and if it is absent, the computer starts every time with the default values. You need to take it out for just a few minutes and then return it to its place. Perhaps the problem will be resolved.
  • Next, you need to check the operability and correctness of the installation of the RAM. It will not be difficult to get the boards out of the system unit, and their functionality in the computer is so extensive that it is quite possible that the monitor does not receive images precisely because of a failure in this component. You can combine this action with removing the battery, since it will take no more than 5 minutes. The RAM cards must not only be pulled out, but also cleaned of dust (not by hand!). It is best to use a tissue that will not leave fibers on the contacts. It is also worth cleaning the slots for installing the boards.
  • Next, you need to check the performance of the video card, since this is the most important device that is responsible for supplying the video signal to the monitor, for the image quality, as well as for the performance of everything that functions in direct contact with the video image. First of all, you need to disconnect this device and clean it from dust. Next, we check the plate on which all contacts, resistors, transistors, etc. are applied, if there are dark spots on it, this indicates repeated overheating of the device, which could lead to malfunctions. The problem can be quickly solved by replacing the video card or connecting the cable to another connector if the computer has a discrete video adapter (built into the motherboard). Repair of a non-working device can only be performed at a service center. In the end, in order to return the computer to full functionality, after a while, you will have to buy a new video card, possibly with better technical characteristics, which will also become an update for the computer.
  • The problem can also be hidden in the power supply unit (PSU), since this device supplies electric current, pre-converting it, to all devices in the computer. Accordingly, a power supply malfunction can lead to the fact that the computer will start up visually, but the current will be enough only to spin up the coolers and blink the indicators. At the same time, the video card simply will not start its work in sync with the rest of the components. The problem is also solved by replacement or repair in a service center.
  • A common problem can be caused by the dusting of the main functional parts of the computer. It is generally recommended to clean the computer on a regular basis, since dusty contacts may not work at startup, dusty coolers will not effectively cool devices, and a dusty video card at some point may even burn out. Cleaning can be done with a regular brush and vacuum cleaner at low power, or using a compressor or can of compressed air.
  • If all of the above methods did not give the expected result, then the last stage of the check should be to assess the performance of the motherboard and (extremely rarely) the processor. A person who does not have a certain set of knowledge in electrical engineering on his own is unlikely to be able to solve the problem and perform diagnostics. Of course, you can re-solder the failed capacitors, but nothing more. If the malfunction lurks in one of the specified components, then you will have to contact the service center.

Usually, all the procedures described in this article, when followed sequentially, will help to cope with this problem. The main thing is to follow the instructions, since any little thing can actually block the video signal to the monitor. If the problem is not solved, then it is worth contacting the service center, tk. repair work must be carried out by specialists. Naturally, if this does not apply to repairing an electrical cable, which can be performed by any tech-savvy owner.

If the computer turns on, you hear beeps and see light signals on the case, but the image is not displayed, then the problem may lie in a malfunction of the video card or improper connection of components. In this article, we will look at several ways to solve the problem when the graphics adapter does not transmit an image to the monitor.

Determining the cause of the breakdown by the BIOS signal code

Each manufacturer uses a different combination of short and long signals, so we strongly recommend our article on this topic about Honor to be familiar with all the signals of their BIOS manufacturer.

Sometimes the problem is with the monitor itself. Check if the power is connected, if it is on and the cable is connected to the video card. Try replacing the cable if possible. In addition, you should carefully make sure that the HDMI, VGA, DVI or Display Port wire is connected correctly.

Alternative options

As a matter of fact, there are no alternative options. If the problem is not solved by the methods described earlier, then no means of the operating system can solve it, since the problem is not software, but hardware.

  • Try to find another adapter. Perhaps he will use a more correct exchange protocol.
  • You can try using a cable with a built-in adapter instead of an adapter. In such devices of the manufacturer, complete exchange protocols are much more often used.
  • Try to use a cable of a different interface to connect the monitor (for example, HDMI 1.4 instead of HDMI 1.3)
  • Use a different monitor.

What to do if the monitor is showing nothing (black screen)

monitor diagnostics

Further, so that I recommend checking. this is the monitor itself (especially in those cases when, after turning on the device, absolutely nothing is shown on it, even for a split second.).

    disconnect it from the system unit and turn it off. Then turn it on again (without connecting it to the system unit!). if the monitor is in order, as a rule, a message should appear on it stating that “the cable is not connected” (“Signal cable not connected!”);

of course, it’s even better to connect the monitor to another device, such as a laptop. This is done quite simply, in most cases one HDMI cable is enough: https://ocomp.info/kak-podklyuchit-monitor-k-noutbuku.html

The monitor is connected to the laptop. the picture is the same here and there / Conclusion: the monitor is working properly!

By the way, the system unit (laptop) for diagnostic purposes will also not be superfluous to connect to another “screen”, for example, to a TV. How to do it better. see here: https://ocomp.info/kak-podklyuchit-noutbuk-k-TV.html

video, card, does, display

Many monitors have one fairly popular “sore”: the failure of the screen backlight. Try shining a flashlight or desk lamp on the screen (see photo below). If through the “haze” you saw a familiar desktop, then there is a problem with the backlight. Its repair, as a rule, is not too expensive and rather quickly removable.

The backlight of the screen is burned out. the image is visible only when the table lamp shines on the surface of the monitor

The computer turns on but there is no image on the monitor

Personal computers, like any other technology, tend to fail. Since a standard desktop is a complex hardware system, the failure of at least one element leads to a disastrous result, since you will not be able to use the computer until you have it repaired. Problems are of a very different nature, and they also cover a variety of reasons, we will talk in more detail about the situation when the computer turns on, but there is no image on the monitor. This problem scares many users, but in fact it is not as bad as it might initially seem. In general, seeing a dark screen in front of them, many begin to think that everything is broken and they will have to buy a new system unit and monitor, but this is not so. Now we will analyze in detail the solutions, as well as the reasons for this problem.

What to do if the video card does not display the image on the monitor

If the computer turns on, you hear beeps and see light signals on the case, but the image is not displayed, then the problem may lie in a malfunction of the video card or improper connection of components. In this article, we will look at several ways to solve the problem when the graphics adapter does not transmit an image to the monitor.

Checking the connection and basic parameters of the second display

In 90% of cases, the problem when the video adapter does not see an additional monitor occurs due to the fact that its use is not enabled in the system.

This can be done in the display properties in Windows. You need to go to the “Screen resolution” tab, where you should click the “Find” button. After the system detects the second monitor, you need to tell it how to use it. There are 3 options:

  • Clone. the same image is displayed on both screens.
  • Expand screens. each monitor displays a different part of the desktop.
  • Use only one of the monitors.

After selecting the required scheme for using displays on both (or on the one that is selected for work, if only one monitor is used), an image will appear.
