Same problem\015\012Picked up this monitor about half a year ago, a Viewsonic A91f+, and have been having some issues for a while now concerning what appears to be shifting in the monitor image, but that is about the best I can describe it as.\015\012\015\012It is most noticable when a large dark area meets a light area, like text or window edges. This "shifting" only occurs on the right side of objects and seems to show most often after I switch resolutions more than a few times, usualy due to gaming. Ive also noticed it happening from running random programs that dont require resolution changing/flickers but this happens FAR less often.\015\012-photograph of the effect-\015\012As you can see, its pretty subtle on a darker background, but Ive had no luck carturing it on a light one. Anyone have any idea as to what is occuring on this monitor and how it could possibly be fixed?\015\012Possibly an issue with magnets? For a while, I did have a small headset hanging off the the monitor on the side that the images "shift" towards, but even taking those off and away havent fixed it.\015\012\015\012Currently the only fix I have found for this is to shut my monitor off for 5-30 minutes, depending on how bad the "shifting" is when I find a time break long enough to fix it.

My monitor only comes on for a few seconds and then goes very very dark, although the content is still there somewhere. But here's where I differ from the majority, if I can get to run System restore, the monitor will work perfectly fine again until the next morning when I need to switch it back on again. Unplugging the power lead from the back and utting it back in again will relight the screen for about two seconds before it all goes blank again.
