I've had this Viewsonic PF790 19" CRT monitor for quite a few years now and it has been used daily since it was new without any issues. Recently I have noticed that large white images will cause the horizontal size to shrink about 1cm overall. I keep my desktop set to black so if I minimize a window I see the picture expand or if I open a window I see the picture shrink. It is possible that it has always done this, but I don't believe that it has. Any thoughs on what might be going out?
