Re: Re: 1920x1200 modeline for Dell 2405FPW
I was successful in getting 1920x1200 to work w/ DVI for the Dell
2405FPW w/ the NVIDIA GeForce FX 5600 vid card on Linux CentOS4 using
this modeline in the /etc/X11/xorg.conf file:
Modeline "1920x1200" 87.66 1920 1952 2280 2312 1200 1227 1233
This was after trying many other modelines. The problem, as revealed
by looking at the /var/log/Xorg.0.log file, was that the vid card
doesnt support a clock frequency above 140MHz, so the usual modelines
would fail. Notice in the above modeline that the interlace option
is used. The display doesn't actually interlace (no flicker).
Also, to force usage of the DVI port, in the xorg.conf file, include
this in the Section "Device" section:
Option "ConnectedMonitor" "DFP-0"
Another factoid: I am running the display through the AddLogic DVI
KVM, where the other machine is an Apple Mac G5 (w/ a Radeon 9600 XT
vid card, also set at 1920x1200 via DVI).
