I am trying to set a custom resolution in Ubuntu. my flat screen monitor is 1440x900 but this resolution is not listed under "displays" settings.

The only options available are 1920x1080(which i am using right now), 1280x720 and 720x576." Nvidia x server settings detects my display as a "CVTE TV 1920X1080 (DFP-1)". Nvidia x server settings does not allow me to set a custom "viewportout" as it comes back to default after applying settings.

In windows my display was not detected automatically, but all I had to do was set a custom resolution in nvidia control panel and it worked perfectly. I'm running ubuntu 13.04 with nvidia proprietary driver (for GTX 570). I have tried HDMI and dvi>vga connections and both don't list my resolution. is there a way to set a custom resolution in Ubuntu that is displayed properly?

Listed at what? What thing you used to list the resolutions? xrandr or something from GUI? Your question is not completed. – ZDroid Sep 30 '13 at 18:03
Is this a TV set rather than a real computer monitor? They are notorious for lieing about their resolution. – psusi Sep 30 '13 at 18:35

This article explains how to add a custom resolution to Ubuntu.

And this thread on Ubuntu has two answers that will tell you how to add the resolution fairly easily
