I just purchased a Samsung T220 monitor and can't get it to work correctly
with my (old) Radeon 9800 Pro card.
I installed the latest Catalyst v. 9.3 drivers and Samsung monitor drivers.
However, when I set the resolution (in anlog mode) to the Samsung native
value of 1680x1050, the desktop image is larger than the monitor and I have
to scroll and pan to see it completely. It seems that the image is
1680x1050, but the monitor views only a window of 1024x768 (or 1280x1024?).
On top of that, the image is stretched horizontally and unclear.
I also tried the Omega drivers, but nothing changed...
If I try to use the digital connexion, I get a small switching test window
analog/digital, then the monitor switches out.
I googled for a solution, and all I found was "it should work", or "mine
works without problem", but never a solution, although someone mentioned
exactly the same problem.
Some people say this resolution is not supported on the 9800, but it appears
in the display settings, so I guess, as many others, that it is supported.
Is the monitor defective? or the video card? did I made some wrong settings?
Please can someone help ?
