So I bought some of the Korean 27" IPS panels that are all the rave. I had
to do this to my
xorg.conf to get them working with the proprietary
Section "Monitor" Identifier "DFP-0" VendorName "First" ModelName "DFP-0" HorizSync 50.0 - 200.0 VertRefresh 50.0 - 200.0 ModeLine "2560x1440_60" 311.83 2560 2744 3024 3488 1440 1441 1444 1490 -hsync +vsync Option "UseEdidFreqs" "0" Option "ExactModeTimingsDVI" "True" EndSection
There's the Monitor section. Note that I've told the driver that I know the exact mode timings for my panel - this is dangerous if you don't know what you're doing. I also had to tell the driver to not use the EDID Frequencies, because they are detected inappropriately (the EDID is actually corrupt as far as the driver knows, because the pixelclock is outside of the range of 'known valid' clocks).
This should help out anyone else that was dealing with this crap like I was :) By the way, they're really pretty.
