Hello
Here are some steps you can try to fix the issue:
Tweak Monitor Settings: The first thing you should check for is the settings built into the monitor itself. Open the monitor’s settings menu using the buttons built into the monitor and try to adjust settings such as Contrast and Brightness. If there are settings for Color, Gamma, Sharpness, Backlight, etc., try changing them as well.
Use Full RGB Color Format: Your graphics card might have been configured to use Limited RGB settings instead of Full. A monitor uses RGB values ranging from 0-255, where 0 is black, and 255 is white. This is RGB full. Television sets, however, use RGB values ranging from 16-235. This is RGB Limited.
For Nvidia users:
Right-click on an empty area on the desktop and select NVIDIA Control Panel.
Expand Video and click on Adjust video color settings.
Under How do you make color adjustments?, click on the radio button next to With the NVIDIA settings.
Switch to Advanced tab and set Dynamic range to Full (0-255).
Click Apply.
Next, expand Display on the left, and select Change resolution.
Scroll down to Apply the following settings. Set Output color format to RGB and Output dynamic range to Full.
For AMD users:
Right-click on the empty area of the desktop and select AMD Software: Adrenalin Edition.
Press Win + R and type control to launch the Control Panel.
Switch the View by option in Control Panel to Small icons.
Click on Color Management.
Select your display under the Devices tab, and click on a color profile from the list below, then click Remove.
Repeat the above step for all color profiles available.
Restart the computer.
Calibrate the Monitor: You can calibrate your monitor in Windows 10 via the in-built color calibration tool. To start the process press the Windows key and type “calibrate display color”. Select the relevant control panel result, as pictured below.
Disable HDR: If your laptop supports HDR, it might be causing the washed-out look. Try disabling HDR in your display settings.
Reinstall/Update Drivers: Fading of monitor due to driver issues can be resolved by reinstalling or updating graphics and monitor drivers.
