As I mentioned in my last post, I needed to use different modeline setting on my Nvidia xorg.conf file than when I had my ATI card installed.

I have no idea why, but it worked. For posterity’s sake, I thought I’d just document ’em here in case I ever needed again.

For my Nvidia card, in the Monitor section of my xorg.conf:

Section "Monitor"<br /> Identifier "DELL 2405FPW"<br /> HorizSync 30-82<br /> VertRefresh 60-60<br /> Option "DPMS"<br /> Modeline "1920x1200" 92.473920 1920 1992 2192 2464 1200 1209 1217 1251 -HSync +VSync interlace<br /> EndSection

And from my ATI x800 xorg.conf:

Section "Monitor"<br /> Identifier "Monitor0"<br /> HorizSync 30-82<br /> VertRefresh 60-60<br /> Option "DPMS"<br /> Modeline "1920x1200" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -Hsync +Vsync

EndSection

They both worked for 1920×1200, the monitor’s native resolution, flawlessly. There’s a big difference in going from 1920×1200 to any other resolution, especially 1600×1200 or below. This monitor is definitely most crisp and bright when running in 1920×1200 like it should be.
