42" 1080p HDTV Resolution Issue

[Knyghtmayre]

I have this model:

http://www.testfreaks.com/televisions/rca-l42fhd37r/

It clearly states that the display resolution for the TV is 1920x1080, yet when I connect it to my PC via the HDMI port on my 9600GT, and I select 1920x1080 as the resolution in the nVidia control panel, the TV says Unsupported? I'm hugely confused. The TV works fine with PS3/360, but when hooked up to my PC I just can't get it to display properly.

9600GT, W7, HDMI->HDMI.
