A colleague at work mentioned that they cannot see all their desktop, they can move the cursor, icons, etc off the screen either side. They say they have tried screen resolution settings, adjusting the monitor settings, all the usual basic stuff but nothing seems to be able to resolve the problem.
I seem to recall seeing something very similar to on this forum a little while back, I've tried a search but for the life of me I can't find it.
In my colleagues case the problem seems to have started since they switched back from using two monitors to one, although they claim to have reset everything.... checked and double checked.
Very hard to give any more info without actually seeing it for myself.
