Description of problem:
Dell 2001FP connected via DVI is limited to max resolution of 1280x960 in System
-> Preferences -> Screen Resolution. System -> Administration -> Display shows
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Connect Dell 2001FP flat panel monitor to PV via DVI.
2. Install FC5T3.
Default and max resolution is 1280x960.
Default and max resolution is 1600x1200.
Looks like this one:

Analog works at 1600x1200 as expected. Only digital (DVI) has problem.

I see the same problem with Fedora Core 5 and a Dell 2000FP (Digital) display.
The X server resolution is 1600x1200, but Gnome desktop is limited to 1280x960.
This appears to be a limit imposed by /usr/bin/gnome-display-properties, not by
This problem was introduced in Fedora Core 5. Fedora Core 4 used to work fine
BTW, bug 187499 is a duplicate of this bug.
More data: This screen resolution limit apparently comes from the "nv" display
driver, which eliminates 1600x1200 despite the xorg.conf settings, with the
following message in Xorg.0.log:
> (II) NV(0): Mode "1600x1200" is larger than BIOS programmed panel
> size of 1280 x 1024. Removing.
Above, the BIOS reference presumably applies to the graphics card BIOS, not the
See https://www.redhat.com/archives/fedora-list/2005-August/msg03936.html for
more detail (Andy Green recommends installing closed source nVidia driver).
Driver NVIDIA-Linux-x86_64-1.0-8178-pkg2.run from nVidia fails to compile under
kernel-2.6.16-1.2080_FC5, although it used to build fine under FC4 kernels.
Support for FC5 from nVidia isn't yet available.
Back to "nv" driver from xorg: Some people suggest adding the following to the
Option "IgnoreEDID" "true"
However, "nv" driver ignores this option:
(WW) NV(0): Option "IgnoreEDID" is not used
and the end result is the same: Mode 1600x1200 gets removed by the "nv" driver.
Finally, digging through bugs at xorg, one finds
https://bugs.freedesktop.org/show_bug.cgi?id=4314 which says:
The "nv" driver currently can't change the BIOS-programmed display timings.
Unfortunately, this is not something that we can fix right now.
...so all of the above suggestions terminate at dead ends.
Our bugzilla database had a catastrophic failure on June 13, 2006
which lost all bug changes from Thurs June 9th onward. I have
bugzilla email records of the time period however, and will be
restoring as many changes as I can manually.

https://bugs.freedesktop.org/show_bug.cgi?id=4314 upstream has been closed
as a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=3654, which
is where this issue is currently being tracked now.
Since this problem is aparently a bug (or limitation, or whatever) in the "nv"
driver, and it appears that it can only be fixed/resolved by Nvidia Inc.
directly, there is nothing we can do about this problem until Nvidia has
submitted patches to X.Org.
As such, we will track the issue in the upstream Xorg bugzilla until a
solution is available and go from there.
Setting status to "UPSTREAM"

Another solution for this bug is to install RPMs from Livna depository
which are built from nVidia's sources and can deliver 1600x1200 resolution.
