Default Problem to clone an DFP (720p) to TV (svideo)


follow situation is geiven. I have connected my Multimedia Computer with an HD-Beamer (720p) and a small TV-Screen. Both displays are riquire. I want to use the TV-Screen to control my music library - the beamer to watch TV. Both displays have the same content, but a differnt resolution. (Beamer: 1280x720, TV-Screen: 600x460). The beamer has a hdmi-connector, zje TV-Screen has only a composit connector (I control this over SVIDEO).

Follows my xorg.conf:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig

I know, that my real tv-resolution not 1024x768 is, but the resolution will automaticly resize (I cant catch the English word - I hope, you understand).

My Problems:
I tried the driver versions: 180.60, 185.18.04, 190.36 - every driver have the same behavoir.

The beamer resolution will set to 1280x768. The beamer works, but the news ticker don't look nice.

(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "TV:1024x768,DFP:1280x720"
(II) NVIDIA(0): Virtual screen size determined to be 1280 x 720

Second problem: The TV-Screen is cutted. On right, I missing 200 points. I Ifraid, the driver mixed the TV and DFP resolution.

Is it possible to get a cloned screen with different resolutions? What have I to do?

Thanks for reply
