I have had dual screen for quite a long time - a 17" laptop and 24" Acer monitor (V243HL). Over a week ago it was working perfectly. However I have just got back from a week long holiday to find that my monitor no longer likes running on its own. I mean if I have it connected and I say I want to only display on screen 2 (the monitor). It changes to 640 x 480 MAX resolution. The only thing I can think of is that I just installed Diablo 2, but then I installed it several weeks ago (only to find it wouldnt work) and the monitor has been working perfectly since then up until now. I have checked for updates to the monitor drivers and found nothing. However this may have simply been the Acer eDisplay software which it was checking for updates for - I will do a bit of searching around to see if it was the drivers.
Does anyone have any idea what this could be? I havent installed any other programs, and I have an Acer Aspire 7738G laptop with Windows 7.
Any help would be greatly appreciated.
