Oh,but there not much to test.On Windows start, it should display windows informations.That's Standard. Look in iMon Software settings.You can choose what else you want to see in the display.
If it doesn't display anything,then there is definitely something wrong.But it could be also a driver related and not a hardware problem.If that's the point,any other "hardware" tests will also fail.
Uninstall driver,Re-Install->Test.
The uncomfortable way: Fresh Windows & driver Install->Test.
Never had any problems with the display for over 3 Years now,with XP and Win 7 x64.
