display

I am trying to connect my laptop (Samsung Series 5 Ultrabook) to my TV (Toshiba WLT66/67 Series) and get it to output to the TV at 1080i (so basically 1920x1080) through HDMI

The issue I have is that in 'Displays' the highest resolution that it gives the monitor is 1280x768, however I know that the TV can output at 1920x1080 at 30Hz as when I use Windows 7 it allows me to do this.

I looked around and found that I could use xrandr to try and get his resolution, however when I do:

cvt 1920 1080 30
    # 1920x1080 29.95 Hz (CVT) hsync: 33.01 kHz; pclk: 79.75 MHz
    Modeline "1920x1080_30.00"   79.75  1920 1976 2168 2416  1080 1083 1088 1102 -hsync +vsync

xrandr --newmode "1920x1080_30.00"   79.75  1920 1976 2168 2416  1080 1083 1088 1102 -hsync +vsync

xrandr --addmode HDMI1 1920x1080_30.00

xrandr --output HDMI1 --mode 1920x1080_30.00

My TV screen just remains blank :( Any help? (if you need any more information please ask)
