I have a TV and I would like to connect my Ubuntu 14.04 laptop to it via HDMI. When I connect HDMI cables between both devices I see am able to detect both devices in my display settings in Ubuntu. But on the TV I see nothing.

$ xrandr

Have also tried

xrandr --output HMDI1 --auto

the command executes with no warning, but nothing happens to the TV screen; it's still blue and displaying 'No Signal'.

I was following the instructions here on Ubuntu forums and tried the command but found this error

$ xrandr --output TMDS-1 --auto

warning: output TMDS-1 not found; ignoring
