Can't get the desired resolution for my monitor

My  home PC has a widescreen monitor with 2560x1080 resolution and I'm using TV 13.2.14327 & Win7 on both remote and home PC's.

When I connect to the remote PC, I can't set TV13 to 2560x1080 resolution.

When I go to View>ScreenResolution, there is no entry for 2560x1080 listed...thus the best I can do is to set at letterboxed 1920x1080.

Both host and remote PC's have no issue displaying at this resolution if I plug this monitor directly.

Is there a way I can add this resolution to the list?
