I am working on Ubuntu 12.04 with extended screen. One of the screens is set to the resolution of 1600×900 (16:9) and the other is set to 1360×768 (16:9).
I have the latest NVIDIA drivers installed. Can anyone suggest how to increase the screen resolution of other screen too? I'm not getting any option in the list to make it 1600×900 — the limit is 1360×768.

You could use xrandr command line tool to set modes
Assuming you have your second monitor connected via VGA it would be like so
xrandr --addmode VGA1 1600x900
Now select that mode
xrandr --output VGA1 --mode 1600x900
You may want to check the manual for your setup.
Here is what it would look like if you had two HDMI devices
xrandr --output HDMI1 --mode 1600x900 --left-of HDMI2 --output HDMI2 --mode 1600x900
To check what output devices you have you can simply type the following into a terminal
xrandr

Looks like you need to add the mode for the DVI-I-0 instead of the VGA try xrandr --output DVI-I-0 --mode 1600x900 and see if that adds the mode. – map7 – 2014-02-28T01:13:03.153

What is the native resolution for that screen? – gronostaj – 2013-11-25T06:40:09.190
Thank you for you reply. I am not sure how to find the native resolution ,until you can tell me but both my monitors are same company product and both are alike. So both have same native resolution of 1600 X 900. – Rana Ranvijay Singh – 2013-11-25T07:03:08.310
