Does not display an image on the monitor for reasons
Why the video card does not display the image on the monitor
The situation when there is no image on a completely working screen is not uncommon. This can be caused by a variety of software and hardware errors and problems. If you are unable to diagnose a problem, start following our instructions, starting with the easy ones and moving on to the most difficult ones.
If the picture still does not appear, then carefully check if you have correctly connected the wires to the connectors on the video card and on the monitor. Check if the monitor is turned on. to do this, press the power button several times.
Reset BIOS settings
If, when turned on, the speaker of the motherboard does not emit any signals (with a sound notification that is not typical for a normal turn-on, you can go to Method 5, which tells exactly about this), incorrect BIOS settings may become a problem. This often applies to motherboards with UEFI that have the potential for overclocking processor frequencies, but this factor is by no means the only critical one. In the course of overclocking problems or other events, the parameters may get lost, and the PC, although it will physically start, will not display the image on the monitor. In this situation, a banal reset of the settings solves the problem. The battery and / or jumper on the motherboard is responsible for this. Use Methods 2, 3 and 4 from the instructions on the following link to perform a correct reset.
If the video card does not display an image on the monitor
The reasons why the video card does not display the image on the monitor can be different. Consider the most popular to avoid such situations in the future.
Correct video card installation
If, after connecting the card to the system unit, the image on the monitor still does not appear, then you need to do the following:
- Check the wires from the card to the monitor. If one or more wires are damaged, the signal from the video card does not reach the monitor, which may be due to the absence of an image.
- Check if the video card is correctly installed in the PCI-Express bus. Quite often, the card is not fully inserted, and therefore the signal does not reach the monitor.
Note: if you inserted a video card into one slot, and the image did not appear, then if there is a second PCI-Express port, insert it into it and turn on the computer again. If the picture appears, then the first slot on the motherboard was faulty.
Note: each BIOS manufacturer has its own classification of audio signals.
Check the integrity of the seals on the video card. This procedure will allow you to conclude whether the card could have been opened and elements in it were replaced.
Carefully inspect the card for visible traces of fire (if you neglect this and insert such a video card into a computer, you can damage other components of the system unit).
If an external examination did not reveal serious suspicions of a malfunction of the card, only then can it be inserted into the system unit. Try turning on the computer and wait for the picture to appear on the monitor.
BIOS signal decoding
In case of problems with the video subsystem, different BIOS manufacturers, when diagnosing and identifying a malfunction, laid down a number of beep codes indicating possible problems in the computer.
- 1 is longer, and two are shorter. video subsystem error;
- 1 longer and 3 shorter. video memory error.
1 long, and then either 2, or 3, or 4 short. errors related to the video subsystem;
- 1 signal and the screen does not turn on. problems with the video subsystem;
- 2 short beeps. no monitor connected.
- 1 is longer and 4 is shorter. no video card;
- 8 consecutive short beeps. problems with video memory.
Depending on the manufacturer, the meaning of the audio signals may vary. If, when the operating system is loaded, the picture does not appear on the monitor, and the speaker emits several sounds, there are problems in the performance of the PC.
The reasons why most often there is no picture on the monitor are quite simple. The main thing is to be careful when connecting. It is better to check the reliability of the connection, the integrity of the wires several times, and then you will never have problems getting the picture on the video card.
The computer turns on but does not display an image on the monitor.
The most common malfunction is when the PC actually turns on, but does not display an image on the monitor. You can see the lights on the computer case and hear the fans running inside, but nothing happens on the screen. There are several possible reasons why your monitor is not displaying information on the screen and it is important that troubleshooting is streamlined.
Check your monitor. Make sure your monitor is working properly before proceeding with the more complex and time consuming troubleshooting steps.
It is possible that your computer is working fine and the whole problem is in the monitor.
Verify that your PC completes its power on and off cycle. In other words, make sure your PC completes restart and shutdown completely.
Often a computer appears to be “not working” when, in fact, it simply has problems waking up from standby or sleep mode.
Note: You can shutdown your computer completely in power saving mode by holding the power button for 3.5 seconds. After the power is completely turned off, turn on the computer and check that it boots normally.
Diagnose the cause by the beep code. The beep code will make it possible to quite accurately find the reason for the shutdown of the computer.
If you could not solve the problem with a specific beep code, proceed to the next steps.
Clear CMOS. Clearing the BIOS on the motherboard will return it to its default settings. Incorrect BIOS setup can cause display problems on the monitor screen.
Important: If clearing the CMOS fixes the problem, make changes to the BIOS one at a time, at least when the problem returns, you will know what changes led to it.
Make sure the supply voltage switch is in the correct position. If the input voltage for the power supply is not correct (depending on the country), your computer may not turn on completely.
Most likely, the wrong voltage will prevent the computer from turning on at all, but sometimes it is not fully turned on.
Reinstall everything inside your PC. Reinstallation will restore various connections inside your computer and very often fix this problem.
Try reinstalling the following:
- Reinstall all internal and power cables
- Reinstall memory modules
- Reinstall the cards you are using
7.Reinstall the processor if you suspect it was not installed properly.
Check the power supply. Just because your computer’s fans and lights are working does not mean that the power supply is functioning properly. PSU tends to cause more problems than any other hardware and is often the reason why the computer does not boot completely.
If your PSU fails the test, replace it.
Important: Don’t miss this test. Power supplies may be under-performing and need to be replaced.
The following steps are the same as steps 8 through 12 in the article Computer turns on and then turns off.
There is no image on the monitor, but the computer is running
A fairly common problem faced by many personal computer users is the absence of an image on the monitor screen, while the system unit functions absolutely normally at first glance. The article will talk about how to diagnose without the help of specialists, what components of the device need to be checked and how to solve the problem that has arisen.
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.
Thank you! Really helped and didn’t have to buy anything
Hello. First, replace the battery with a mat. board. As trite as it sounds, it often helps. Try working on the integrated video card for a few days. If there are no such problems, then the end of the video card is coming. Is the power supply many years old? If yes, then it washes and that’s it. Operatives since 2 shawls, try to work with each separately. If nothing works, then most likely the checkmate dies. pay.
Mointor via HDMI connection or via adapter?
And what about the monitor itself can be? When I disconnect the monitor from the video card, nothing writes on the monitor, only a black screen and the button on the monitor blinks. I tried all the methods with both the video card and the operational one, nothing helps. However, when the computer stands for 2 hours and restarts, the picture appears. What could be the problem with the monitor?
We will try, thanks. And then the head does not understand after work
Thank you very much. Step 6 helped. Disconnected the non-working floppy drive and it worked!
While configuring the router, I ran into the following problem. the monitor image was shifted a couple of millimeters to the left. And the cursor also “floated away” to the left, not lingering on the edge of the monitor. over, it was both in programs and on the desktop. And on the right, a black strip formed the same couple of millimeters wide. But what is there to tell, see for yourself (lower right corner and the folder crawling over the edge):
It is impossible to show this in the screenshot, because the screenshot “photographs” the active area controlled by the system. And here it seems that the pixels have stopped working.
Troubleshooting Monitor (Image Shifting)
Hello! Today there will be a small note about such an everyday problem, which may not be common, but annoying decently. If we discard the phrase in parentheses of the title of the article, then this topic cannot be fully disclosed in a number of extensive articles. In fact, I will talk about one little problem and directions to dig when other problems arise.
General Technique for Troubleshooting Monitor Problems
1) We look at the physical connection of the monitor to the motherboard connector. Trying to pull out and reinsert the cable.
2) We check with our hands the serviceability of the cable (whether there are any kinks).
3) Checking the monitor power connection.
4) If the image does not appear on the monitor, then most likely the video card is covered. You need to take another and try to see if the monitor will work with it. If not, then the end of the monitor has come.
5) If you still saw the image, but it is distorted, then go again to the context menu of the desktop. Screen resolution. Here you need to set the standard resolution of your monitor, specified in the instructions. If CRT monitors (similar to TVs) allow you to change the resolution without any problems, then their LCD counterparts should only have a standard one. Otherwise, the image will be blurry.
6) If the image looks like a ladder, like here (it is best seen on the basket label): then go to the additional parameters (as in point 2 of solving my problem), go to the “Monitor” tab and below there is a color rendering quality mode switch. So there you need to select 32 bits (True Color): Then the image will become smooth and the gradients will be invisible:
smooth image with normal gradients
7) If the text still looks fuzzy, crumpled, like printed by a printer, in which ink is running out, then most likely you have disabled the Clear Type mode. To enable it, in the same screen setting at the bottom, click on “Make text and other elements larger or smaller.” A panel will appear:
make text and other elements larger or smaller
On the left in the menu, go to “Setting the ClearType Text”. And in the window that appears, put a checkmark “Enable ClearType”. At the same time, you can immediately see the changes on the monitor and understand what’s what. Click the next button and choose the best text options for you. It is not difficult there, so I will not give screenshots.
8) If the interface elements on the screen look small, then in the menu, which we entered in the 7th paragraph, select “Other font size (dots per inch)”. A window for selecting a scale will appear:
Here you can adjust the scale to within 1%. However, I do not advise you to get carried away, because, for example, at 140% magnification, not all elements will fit on the screen. Especially at low resolution like mine.
9) If there are any stripes, blurring or other artifacts on the monitor, then you can update the video card drivers. To do this, go along the following chain “Context menu of my computer. Management. Device Manager”.
In the middle window, go to the video adapters and click on the name of the video card. In the pop-up window, go to the “Driver” tab.
Here we select “Search automatically for updated drivers”. I found drivers without problems. If you cannot update the drivers in this way, then go to the manufacturer’s official website, find your video card model, download the latest (or penultimate) version of the driver and update it manually. It is better to download the penultimate drivers, because the latter may be raw (unfinished).
If the picture is still displayed incorrectly, then there may be program conflicts. I myself did not come across this, but on the Internet I met people who said that after reinstalling the system everything worked fine. You can try this method as a last resort.
I will not talk about color calibration here. Because this is already an improvement in the reality of displaying a picture. And here either special tools or skills are needed (for amateur tuning).
I’m 100% sure that even those lying on the surface did not mention a bunch of details. So if there are any problems, please contact us, we will think together.
How I solved the problem?
Everything turned out to be very simple. It was enough to change the frequency of the monitor (LCD monitor). Now I’ll show you how it’s done.
1) Go to the desktop context menu, Screen resolution (in Windows 7). 2) A menu with screen settings appears. Click on “Advanced options”. 3) The characteristics of your video adapter (video card) will appear. Go to the “Monitor” tab. The important drop-down menu here is “Screen Refresh Rate”. We set the maximum refresh rate of the screen. By default, I had 60 Hz, which was the cause of the problem. After that, the image should move to its place.

Thanks, helped to restore the image to full screen.
what to do if there is a black strip at the bottom of the screen and the cursor can be moved outside the visible?
Is there an “Auto” button on your monitor? It is also possible that there is such an item in the menu that you need to select. after that, the monitor should automatically align the image on the screen.
Try in the device manager, turn off the monitor, and click on auto.
LORD THANKS VERY MUCH. I was already so scared. You are the best
I was interested in the question of the vertical elongated screen when turned on, before that it worked fine with these settings, what to do?
Thank you very much, the first method with hertsovka helped, did not expect.
I have the maximum number of GCs and it didn’t help me
Thank you very much. It turns out that the properties of the video adapter have crashed. Eternal health to you, friend!
Dear buddy, thank you so much for the solution you provided to this small but nasty problem)
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.
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.
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.
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.
