hdmi

When connecting my TV over HDMI, it shows up in display settings and xrandr:

Aspire1825PTZ:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

Aspire1825PTZ:~$ xrandr Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192 LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 256mm x 144mm 1366x768 60.0*+ 1360x768 59.8 60.0
1024x768 60.0

However, the resolution is way too low and the screen remains black. Everything works fine in Windows, but I'd rather not reboot just to watch a film...

Could anyone help me please?
