I'm using an S3 Trio32/64 PCI adapter and my monitor is a generic 1280x1024. It's worked fine until recently. Normally, the viewable part of the monitor goes over the whole screen (naturally). But now, I have a huge margin of darkness on either side of the viewing area. It's as if the control to contract the horizontal viewing area has been rolled to one side -- that of course, is not the case. I'm pretty sure the monitor itself is the problem and not the card. Thanks very much for any help, information or suggestions.
