<div dir="ltr">Hi everybody, I'm running Linux 2.6.21 radeonfb driver (rel. 2.0) on an ATI X300 sapphire. The produced DVI-D signal (on a 1600x1200x16 resolution) is not as clear as the one produced by WINXP in this way: pixel timing clock is OK and so is each data wire, but 0's and 1's falls outside regular DVI eye (I'm measuring with a 6GHz high-impedence diffrential probe). Lots of "buzzing" is produced on my HP montor when I use a 5m DVI-D cable: this does not happen under WIN XP. I'm afraid something is missing from the driver concerning signal (some hidden tuning?) Can someone help? Thanks in advance! luigi ================================== </div>
