Hey guys, I just solved my problems! Well, at least the ones regarding my new tft ;-) Ok, here is what I did: i mounted my old hdd and installed windows xp (shame on me :-) It worked out of the box with the radeon drivers from Dell. The app reported 60Hz refresh-rate. However, the monitor OSD only showed 50Hz. I than tried to create a modeline with cvt for 50hz. But that one didn't work. But using the reduced blanking mode (-r) it does. This is the modeline: $ ./cvt 1920 1200 50 -r # 1920x1200 @ 50.00 Hz Reduced Blank (CVT) # field rate 49.97 Hz; hsync: 61.42 kHz; pclk: 127.75 MHz Modeline "1920x1200_50.00_rb" 127.75 1920 1968 2000 2080 1200 1203 1209 1229 +HSync -Vsync Maybe this is useful for somebody else. Thanks Alex + Felix for your help.
