I recently got a Sony Bravia HD TV but can't connect it to my Ubuntu laptop. I've a Dell with Intel GM965 Graphics. When I connect to the TV using an HDMI cable, it says:

Unsupported signal, check device output.

It is detected by Ubuntu just fine. I tried with different resolutions in the display settings but couldn't get it to work. Also, I couldn't find settings for refresh rate (I'm on 11.10).

The TV/Cable is fine as PS3 works perfectly well.

Could you edit your question to include the output of xrandr -q? – James Henstridge Jul 25 '11 at 2:24

Guess what, I replace the HDMI cable and it worked. It's quite weird though. PS3 works with the old cable but laptop doesn't. Both of them work with the new cable.

I'm going to vote to close this since it was a hardware issue, glad you got it sorted though! – Jorge Castro Jul 27 '11 at 13:13
