hello all,

I just installed 11.04 on my PC. I use my TV as my monitor because I use this machine to stream from Hulu, Netflicks or Icefilms. Ubuntu does not detect the resolution I want to use, which is 1152x648. An odd ball res I know, but everything fits best on that setting and I'm not concerned with HD.
this is what I've tried so far:

$ xrandr --addmode DVI-0 1152x648
xrandr: cannot find mode "1152x648"

i then tried:
$ xrandr --newmode "1152x648_60.00" 59.25 1152 1200 1312 1472 648 651 656 674 -hsync +vsync
then:
$ xrandr --output DVI-0 --mode 1152x648
and it returned:
xrandr: cannot find mode 1152x648

I checked my work by entering xrandr and the mode I added was in the s video settings but not available for the DVI-0 monitor.

How would I go about adding this resolution to the DVI-0 output?
Below I pasted what prints out when I input xrandr...not sure if it will help diagnose my error.

thanks in advance
