Using external monitor via HDMI

Hi  I have a problem. I wanna use my TV as a monitor. But when I connect it most part of the TV shows the laptop screen. But I can also see three "other backgrounds"

Heres a picture: http://data.fuskbugg.se/skalman02/4e490 … 4_scrn.jpg

I have Intel card and I've tried

xrandr --auto, I've tried scaling it. But nothing works...

HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 160mm x 90mm

Re: Using external monitor via HDMI

It seems like "auto" doesn't work.
Have you tried to set the resolution manually with xrandr?

xrandr --output HDMI1 --mode 1920x1080
