One of our users has reported that his monitor is flickering constantly and is causing him some problems, eg headaches, sore eyes. I have had a look and there is a slight flicker.
Here are the things I have tried so far that haven't helped.
I tried changing the refresh rate to see if that would help, but the flickering was still there.
Installed the latest monitor driver.
Moved the monitor away from the wall where all the cables are located.
Replaced the monitor with a brand new one.
Replaced the monitor with a used, but working one.
Replaced the PC with one that I know works without any problems.
The user sits in his own office and there are no other computers near him.
Any suggestions and ideas would be very welcome.
