Proview 15" TFT monitor problem

Somewhat unusual fault, the monitor is under warranty so I don't need to
fix it, but wondered whether anyone else had seen it..

Basically it works fine at 640*480 or 800*600 but when used at 1024*768
the monitor goes competely white in about 2 seconds.
If the menu button is pressed right at the start then the OSD menu can
just be seen, until the display becomes completely white.

Weird, and it's not the PC, because another (identical) monitor is fine.
The monitor is specced for 1024*768 from 56Hz to 85Hz, BTW :)
I suspect it's the ADC that's hosed, but it just seems strange, I'd have
expected a garbled display rather than just white like a failed panel.
