After my computer has been switched on for an hour or so - I am getting an intermittent problem with the display that is random and not associated with a particular programme or activity.
There will suddenly be a slight "shimmer" of the display - and the colour balance of the screen will change. Still a very acceptable picture in quality - but seemingly a change from daylight to artificial colour balance or vici versa.
After a while it will change back again on its own.
What is the most likely cause, monitor, graphics card or graphics driver ?
