Hello...

I'm trying to get away from my old power consuming mythtv box, where I have an integrated Radeon HD 4200, and switch to an a little more clever setup.
The issue is that I live in EU and get 25/50Hz television broadcasts, and the TV only reports (according to xrandr) 60Hz resolutions.

My old box (still running) also gets 60hZ only resolutions, but there I can run:
Code:
xrandr --newmode 1920x1080@50  148.50  1920 2448 2492 2640  1080 1084 1089 1125 +hsync +vsync
xrandr --addmode HDMI-0 1920x1080@50
xrandr --output HDMI-0 --mode 1920x1080@50
However if I try that on the intel based machine i get:
Code:
$ xrandr --newmode 1920x1080@50  148.50  1920 2448 2492 2640  1080 1084 1089 1125 +hsync +vsync
$ xrandr --addmode HDMI2 1920x1080@50
xrandr: cannot find mode "1920x1080@50"
I've tried a bunch of the "UseEDIDFreqs" "FALSE" type of options but I only get the "not used" report in the Xorg.0.log
Does anybody have a trick to adding 50Hz resolutions. I would like to avoid running my own kernels and xorg packages,
but if it's nessecary It could probably be done in 3-6 weeks (children in the household).

yours

System Config/Info:

I'm running on a: Intel Desktop Board DQ77MK Media Series with a Intel Xeon E3-1265LV2 cpu.
I Run XEN and have made an HVM running debian with the primary display passed through into the VM.
This is running fine (I get audio over DisplayPort to an HDMI on the TV), but results in some strange looking lspci'es.

The machine is running debian stable (squeeze) with linux-image-3.2.0-4-amd64 and the xserver-xorg* packages from testing (wheezy).
