When I view a webpage and scroll down to the bottom using the slider, the screen dims. Scrolling back up returns the brightness. Think it also happens in games, rarely (screen dimming).
Have reseated the graphics card and swapped the DVI port the monitor plugs into, still happens. Don't have a second monitor to test it on.
Is it the monitor or graphics card that's dying!
