View Full Version : [SOLVED] Resolution 1920x1200 not available in nvidia-settings

I just bought a new 24inch monitor that supports the resolution 1920x1200. Unfortunately, the nvidia-settings dialog does not have this resolution as an option (currently running on 1920x1080). The graphics card is Geforce 6200 (should support the wanted resolution), and the monitor is connected with the VGA cable (if that matters).

How do I add this option?

Thanks!

Are you opening nvidia-settings with:

gksudo nvidia-settings??????
You must do that to make changes.

Yes, I have tried that - 1920x1200 is not available in the resolution drop-down box. How do I add it as an option? Is there another way to set the resolution?

Which driver did you use?

All the cheap TV display 16:9 monitors are 1920x1080 native.
The expensive 16:10 computer monitors from Dell iApple & LG245 etc are native 1920x1200.

Your monitor can have a input video mode capability that exceeds its native resolution; this is a function of the pre-scaler.

The VGA connection, in new HDMI monitors, can limit the options to standard video modes & 60Hz only modes.

Your /var/log/Xorg.0.log will list the EDID modes read from the display...

The monitor is a relatively expensive Dell U2410. I bought it partly because it is native 1920x1200.

These look like the only lines relevant from /var/log/Xorg.0.log:


[ 998.316] (II) NVIDIA(0): Setting mode "CRT-0:nvidia-auto-select@1920x1200+0+0"
[ 1010.455] (II) NVIDIA(0): Setting mode "CRT-0:1920x1080@1920x1200+0+0"
[ 5727.079] (II) NVIDIA(0): Setting mode "CRT-0:1920x1080@1920x1080+0+0"


The driver I am using is the newest one available from ubuntu (the "version current" in the Additional Drivers dialog).

That almost looks like your xorg.conf file has a mode entry for 1920x1080 & the driver is then excluding the 1920x1200.

Edit/copy/delete your /etc/X11/xorg.conf file & reboot.

If you have a simple video-monitor setup, then the xorg.conf file is not needed.

Ok, I tried that and it worked! Looking at the original xorg.conf, I am not quite sure what caused the problem:


Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
EndSection

Section "Module"
Load "glx"
EndSection

Section "Device"
Identifier "Default Device"
Driver "nvidia"
Option "NoLogo" "True"
EndSection

In fact, I am unsure what created that xorg.conf file. Anyway, thanks a lot!
