TV Refresh rate not quite right
I am very pleased with my new ubuntu desktop. There is just one thing I need to get working for it to be perfect.
I have a Dell XPS One 27 with HDMI out. When I connect my Amp / TV to it, it does indeed show up in the displays program. It works, but not at the native resolution of the plasma display.
When I click 1920x1080, the TV goes blank. I am convinced that the refresh rate being fed to it, is not quite right.
How would I change the refresh rate, so that I know I am outputting 1920x1080 at the right refresh?
