LCD monitor - Loss of brightness

April 2017



Your computer is working, but the screen is almost unreadable? The possible causes are:

Screen brightness

  • If you have a desktop computer, you can try to adjust the brightness level using the dedicated button located on the screen itself.
  • If you have a laptop, a combination of the Fn key and the key with a "sun" icon allows you to change the brightness level.

Screen Resolution



Go to the Control panel and check that your video settings are correct set (luminosity. ..).

Sleep mode



Some laptops will automatically go in sleep mode once the battery is down.

A stucked key



Verify that key (including start / stop buttons, and screen saver) is not stuck.

Overheating



Overheating of components like the GPU or processor may lead to this type of problem.

Operating system issue



Sometimes restoring to an earlier or a complete reinstallation of the system may solve this issue.

Graphics Card



It may be that your graphics card is faulty! Try to update or reinstall the drivers. Eventually test it with another screen.

Faulty power inverter


In most cases this problem is due to a faulty power inverter ... refer to the technical manual to replace it.
