I have one of these monitors. It works great. What graphics card do you use? What type of machine? What kernel? What XFree86? Oscar.
XFree86 = 4.2.1-9
Kernel = 2.4.21-ben2 with my custom config
grahics card = rage 128 standard with the G4 (it was a 450 G4 but I replaced the chip to an 800mHz (the 450 chip died on me)) I have a Nevidia graphics card which I will swap out the rage 128 but after I can get every thing to work well
