Hi!
I've connected LCD monitor (19" Samsung SyncMaster 193P - with 1280x1024
pixel matrix) to my PC via DVI (digital) connector. Unfortunately, I'm
unable to obtain screen resolution 1280x1024. After setting such a
resolution screen is getting blank, sometimes it moves into suspended state.
I had the same problem on various linux distros: FC3, FC4, Mandrake 10.1,
Knoppix. I tried to modify xorg.conf, add ModeLine settings but with no
effects.
Can anybody help me to resolve that problem?
