  • Weird Matrox G400 Problem

    I have an 18" Philips analog flatpanel. Have it hooked to several PCs via a Cybex 4 port electrical switch, at resolution (native) 1280x1024. Cards: 1 G400 DH, one G400 Marvel

    Worked well for a few months, now the images is very unstable and completely unwatchable. A horizontal line constantly has small waves in it, the whole screen acts up like that.

    Manual adjustments do squat.

    So I figure my monitor is shot. A slightly lower res works (1280x960) and luckily the Philips allows real res rather than scaling. So it works, have a black bar top and bottom, but better than nothing.

    However, now I plug in another PC, with a Radeon (cheapo old Radeon with 32MB SD).

    Guess what. 1280x1024 is rock solid.

    So both my Matrox cards fail at the same time with the same issue?? Or do they have some weird timing issue the flatpanel can't handle??

    Any ideas?

    are you sure you mean horizontal and not vertical?
    no matrox, no matroxusers.

      Yup. It's just a manner of describing it though, the whole screen is 'moving', so vertical lines also distort.
