Could be the same problem that I had with a GeForce 6150, connected
to a Iiyama AU4831D flat panel. This panel has a native screen
size of 1600x1200 pixels, buf Xorg refused to use 1600x1200 and
was using 1024x768 instead.
The AU4831D panel reports two video modes through EDID data:
- the first one: [EMAIL PROTECTED]
- followed by a second mode: [EMAIL PROTECTED]
The nvidia driver apparently uses the first EDID mode to
find out the display's native panel size; and later on
rejects the 1600x1200 mode, because it is "bigger than
the panel's native resolution" (but that's not true).
I found three workarounds:
1. Workaround
I connected a newer Iiamya Prolite H511S, which also
has a resolution of 1600x1200. This panel returns only
*one* mode with EDID data, a [EMAIL PROTECTED] mode.
I saved the H511S binary EDID data using the nvideo settings
applet, and I was able to use the binary EDID data file
/etc/X11/edid_PLE511.bin with the other AU4831D panel,
by adding the following to the nvideo "Device" section
in /etc/X11/xorg.conf
Option "CustomEDID" "DFP-0:/etc/X11/edid_PLE511.bin"
With that option in xorg.conf, I was able to use 1600x1200
with the AU4831D panel.
2. Workaround:
As a refinement, I removed the CustomEDID option,
restarted Xorg, saved the AU4831D panel's binary EDID
data from the nvidia settings applet, and used mdb
and swapped the two modes in the binary EDID data,
so that it reports the 1600x1200 mode before the 1024x768
mode.
Using a similar Option "CustomEDID" line with my patched
EDID file, I was able to use 1600x1200 with the AU4831D.
3. Workaround
Instead of using hacked EDID files, another option was to
add the following to the "Screen" section in /etc/X11/xorg.conf:
Option "ModeValidation" "NoDFPNativeResolutionCheck"
