Resolution Problems with Two Monitors and Resolution Problems in General


I'm having some issues with adjusting resolutions. I'm currently using two DELL monitors (models P1110 and P1130) which have detected just fine (I'm using Slackware 12.1, by the way) through xorgsetup, but the P1130 started at 800x600 (which for a 20 something inch monitor is ridiculous). After fiddling with modelines and modes and anything that had the numbers 1600 and 1200 next to it in the xorg.conf file, I now have the P1130 at 1600x1200 (at 65hz though) and the P1110 is at 1152x864. I would like them both to be at 1600x1200 at 70Hz+. If someone could help me out with this, that would be really great. I'll post my xorg.conf file, as well as the dump from lspci.

xorg.conf:

Why did you comment out the higher ranges?
Quote:
HorizSync 30-81 #30.0-121.0
VertRefresh 56-75 #48.0-160.0
If you have CRT monitors they support for sure higher ranges. Then create a new modeline which uses a higher refresh frequency - fiddle around with "xvidtune".
