A flickering or floating screen is experienced by many computer and laptop users. After long hours of use, the device may “get tired”, the monitor tends to lose brightness, the picture may float or tremble. If the screen twitches, this may indicate a small problem, and a major problem. In some cases, you can independently deal with the issue. Before you do anything, you need to figure out the cause of the image breakdown.
How to find the reason why the screen does not work well
Finding the cause of the problems with the screen is not always easy, so you need to check all the components in order, as the problem becomes more complicated. They begin the test with a cable, it can be reconnected or replaced, then go to the video card. In the case when it is not possible to immediately find the reason, you can get into the settings, then check the matrix.
Cable. The problem with the cable is very widespread, since it is he who is responsible for connecting the monitor to the computer. Any defect in the connecting device can cause damage. If the contacts are erased, the wire is broken or torn, the cable ceases to fulfill its function due to manufacturing defects. To check this option, you need to connect the monitor using a different cable. If everything works, then it is in him. The wire can be replaced and returned to the store, or try to return for repair.
Video card Damage to the video card also has negative consequences. It may not be the graphics chip itself that is broken, but the cable connector. To confirm this malfunction, just try connecting through another connector. Perhaps DVI was constantly used, you can connect via VGA or HDMI.
REFERENCE! If you have multiple DVI connectors, you can try to connect through them. If the problem persists when using another connector, then the problem is in the input.
It appears very often due to careless use or pollution.
If the matter is not in the connector, then you need to replace the graphics chip. You can get a video card and try it on another computer. When working properly on someone else's PC, you need to contact a special repair center for help, which will make detailed diagnostics and repair it.
The card might not be compatible with the device. Due to the increase in memory frequencies, the picture may begin to behave strangely, twitch, ripples occur. You must open the program through which overclocking was carried out and reset all settings. Even overclocked cards have problems, so it’s better not to experiment.
Incorrect setting. Another reason for a twitching monitor is incorrect settings in which the user could make a mistake. When image resolution is set, inexperienced users often set the highest resolution. This leads to interruption of the picture and it starts to twitch. You must set the correct frequency and resolution. To do this, you must:
- Go to the menu;
- Select a control point for your video card;
- Open a tab with the name "display";
- Find there a “resolution change”, here we change the frequency and resolution, in accordance with the characteristics of the video card. Next, click on the save button, and all problems should disappear.
The frequency should not be low, a shaky image can damage your eyesight.
Matrix. If all causes of the breakdown have been ruled out, there may be a problem in the matrix. This is the most difficult problem, since it can only be fixed at a service center. Repairing the matrix is very expensive, so it’s sometimes easier to find a new monitor.
What to do?
In some cases, you can get rid of breakdowns at home. With a broken cable, it is purchased independently in a store. It is better to photograph the input or cable model to replace it with a suitable one. The problematic video card can always be replaced with a new one; the connector is repaired at any service. Settings for proper operation can be found on the Internet, or reset to factory settings. The “sick” matrix is expensive to change, so this problem is the biggest.
REFERENCE! The display also affects the electromagnetic field in the apartment, you can change the location of the computer and try to turn it on. Do not put the device next to technical devices, they affect the PC. If the computer does not have enough power, it can also fail.
It’s best to plug the power directly into the power outlet rather than through adapters. Usually, large household appliances are included in the adapter, which takes all the energy to themselves. In the absence of external reasons, you should not climb inside the monitor yourself, since you can only worsen the situation. With proper use of the computer and connections, everything should work properly.
