I use Windows 7. Fairly new to it. Sometimes, the screen dims and brightens repeatedly - it's not intense, but noticeable.
 
Now something has changed about it, and it has acquired a pale, but distinct green cast. The whole proceess affects everything from browsers, to videos and movies, to PC games, and, of course the desktop.
 
WHY is that dimming an attribute of W7? Sometimes the bottom right corner warps itself briefly, too - and again, no matter what I'm doing on my PC.
 
I find it obnoxious. Even more so in green.
 
At the very least, I want an explanation. Ideally, I'd like a way to get rid of it.
 
Thanks
Holly

It sounds like a video issue, is the computer new?  Also please provide all system specs, it helps the guys out to know what they are working with.

When you reply to OldPhil, can you also include details of your monitor please. I agree with him that this is almost certainly a video issue, and while it could be a problem with the video card in your computer and/or its drivers, it could equally well be a problem with your monitor.

 

One thing I can assure you of, it is not 'An attribute of Win 7' !   Microsoft may be guilty of many things, but foisting 'interesting' screen displays upon us is not one of them, with the possible exception of Win 8 !
