What causes the computer screen to turn yellow?

The reasons why the computer screen turns yellow: 1. The monitor data cable or poor contact. You can replug and unplug the monitor data cable. If it is normal, it means the monitor has a bad contact; 2. The internal lamp of the monitor is prone to aging. The light emitted is abnormal, resulting in screen color problems; 3. Poor contact with the graphics card, too much dust on the gold finger and abnormal graphics card driver; 4. The graphics card driver is missing, the graphics card driver is incompatible with the system, the graphics card driver is damaged and Unable to install graphics driver.

Operating system for this tutorial: Windows 10 system, Dell G3 computer.

The monitor is an essential output device for the computer. It is the most important computer component besides the CPU, motherboard, memory, power supply, keyboard, and mouse. The monitor is connected to the computer host through the "display interface" and bus. , displays various computer data and information on the LCD screen, but during use, sometimes the computer screen turns yellow. What is the cause? The following editor will introduce to you the monitor screen. The causes and elimination methods of yellowing are provided for reference.

Causes and troubleshooting methods for monitor screen yellowing:

The most common cause of computer screen yellowing is monitor failure, such as the signal transmission quality of the monitor’s data cable Caused by poor contact, broken data cable or computer graphics card problem.

1. Monitor data cable or poor contact causes

When the monitor has a yellow screen failure, first re-plug and unplug the monitor data cable to see if the monitor returns to normal. If it is normal, explain It is caused by poor contact. If it still doesn't work, we can use the replacement method and try a new monitor video cable. If the problem persists, please continue the following checks.

2. Monitor failure

Generally speaking, the life of the panel inside the LCD monitor is very long, but the aging of the lamp inside the monitor can easily lead to abnormal light emission, resulting in screen color problems. , so screen yellowing caused by monitor failure is relatively common.

Switch the monitor to another host for testing to see if the monitor displays normally. If the fault is eliminated, it means it has nothing to do with the monitor itself. If the fault is still a yellow screen, it proves that there is a problem with the monitor. , in this case, it is recommended to send the Xunwei Quick Repair professional repair structure for inspection.

3. Graphics card failure

If you replace the monitor and data cable and test the screen on another host and everything is normal, it means there is an internal hardware problem in the computer host. The most likely cause is a graphics card failure. For example, the graphics card has poor contact, the gold finger of the graphics card is too dusty, the graphics card driver is abnormal, etc.

Shut down the computer first, then take out the graphics card, clean the dust, wipe the gold finger of the graphics card with an eraser, and then try to install the graphics card back again. If the problem is solved, the graphics card installation contact is poor or there is too much dust. If the problem persists, try updating the graphics card driver again. If the problem persists, the graphics card itself may be faulty.

The possibility of yellowing of the computer screen caused by the failure of the graphics card itself is relatively rare. It is recommended to take it for maintenance. If the CPU has a built-in core graphics card, you can remove the independent graphics card and try connecting the monitor to the VGA interface of the motherboard. If the screen is normal, you can basically conclude that the independent graphics card itself is faulty!

4. Graphics card driver issues

Graphics card driver problems usually cause system instability and crashes, blurry screens, incomplete graphics for text and images, yellow screens and other malfunctions. Graphics card driver failures mainly include graphics card driver loss, graphics card driver incompatibility with the system, graphics card driver damage, and inability to install the graphics card driver. For graphics card driver failures, generally first enter the "Device Manager" to check whether there is a driver for the graphics card. If not, just reinstall it.

If there is, but there is a yellow "!" on the graphics card driver, it means that the graphics card driver is not installed properly, the driver version is wrong, the driver is incompatible with the system, etc. Generally, delete the graphics card driver and reinstall it. If there is still "!" after installation, you can download a new version of the driver and install it. If you cannot install the graphics card driver, there is usually a problem with the driver or the registry.

In general, the yellowing of the computer screen is caused by two major problems, one is the graphics card, and the other is the monitor. When we solve the problem, we can adopt the idea of ​​​​first simple, then complex, first Check whether the video cable and graphics card are installed normally, and then solve it according to the troubleshooting method mentioned above. If the problem cannot be accurately identified and there is no replacement hardware for replacement and troubleshooting, it is recommended to take it to a repair organization such as Xunwei Quick Repair Overhaul.
