I'm on 8.10 (laptop) Attached laptop to tv monitor through HDMI. The 'configure display settings' recognized the monitor. I picked a resolution for the tv monitor, then it said that it "detected that the virtual resolution must be set in the config in order to apply the settings". I let it do that automatically, however I got still "no signal" on the tv screen.

I modified xorg.conf. Now when I enable the tv monitor by choosing a resolution (after connecting the cable) it 'goes' to my laptop screen, making it really wide so I can't even see my panels.

It seems that is does not really 'output' to the tv monitor. Below is my xorg.conf. Anyone can tell me what to modify/add so that I can use the external monitor?

A new xorg.conf below, however still the same: as soon as I select a resolution for the external monitor, this takes effect on the laptop monitor, and the external (tv) monitor still says "no signal"

Ahhh, well... it was just the 'Virtual' mode.. External monitor is capable of 16:9, so the right Virtual would be 2800 900.. that solved it for me.
