Refresh Rate Help

RaZ0r! · 05-09-06, 09:24 AM

I cannot seem to figure out how to get my monitor set to 1280x1024@60Hz. There is something strange about this monitor with the 7800 GS, as even under Windows it is a struggle to get it set correctly, I have to use custom timing.

Anyway, here is my xorg.conf and log file. Could someone let me know what I need to do to get my monitor to run at 1280x1024@60Hz? Thanks.

look at /var/log/Xorg.0.log.

look for something like; (II) NVIDIA(0):"1280x1024_60" : 1280 x 1024 @ 60.0 Hz

*

then edit xorg.conf to change; Modes "1280x1024" to Modes "1280x1024_60"

* if a line like that didnt appear in the /var/log/Xorg.0.log, then you might need to set; Option "UseEdidFreqs" "false" in xorg.conf. but be sure your monitor can operate at they res/freq desired first.

huh, that's odd your xorg.0.log doesn't seem to have resolution/refreshrate specific choises lines of the format i mentioned. try seeing if the edit false option gets past that.

Thanks for helping. I finally figured it out. I first tried specifying my mode "1280x1024" and put my rates in for my monitor, limiting the refresh to 60Hz. Did not work. Then I disabled EDID support and it worked like a charm. Apparently EDID wants to force my monitor to 75Hz even though the actually EDID recommendation is 60Hz.
