The max resolution i get with a Dell 2001FP connected via DVI cable to a
nvidia5200 graphics card using the nv driver is 1024x768. The monitor is capable
1600x1200 and this is what i have configured. Looks like my panel is only
detected as 1024x768 panel.
Here is the relevant part of the /var/log/Xorg.0.log file:

(II) NV(0): Monitor name: DELL 2001FP
(II) NV(0): Ranges: V min: 56  V max: 76 Hz, H min: 31  H max: 80 kHz, PixClock
max 160 MHz
(II) NV(0): Probing for EDID on I2C bus B...
(II) NV(0): I2C device "DDC:ddc2" registered at address 0xA0.
(II) NV(0): I2C device "DDC:ddc2" removed.
(II) NV(0):   ... none found
(--) NV(0): CRTC 0 is currently programmed for DFP
(II) NV(0): Using DFP on CRTC 0
(--) NV(0): Panel size is 1024 x 768
...
(II) NV(0): Mode "1600x1200" is larger than BIOS programmed panel size of 1024 x
768.  Removing.
(II) NV(0): Not using default mode "1600x1200" (unknown reason)
(II) NV(0): Not using default mode "800x600" (bad mode clock/interlace/doublescan)

Please fix!
Thanks!

The log file seems to indicate that the driver is detecting a maximum
panel size of 1024x768 from the video BIOS, which could indicate a bug
in the BIOS.  This type of problem generally needs to be diagnosed
directly by Nvidia, as it likely requires low level hardware knowledge
only the Nvidia engineers have access to.
