  to verify. Even the Xorg.0.log lies about the fact that 50Hz are active
  but in reality it uses 60Hz. Maybe nVidia has fixed that in the meantime.
 
 To watch HD broadcasts I use the hdmi output on my laptop.
 It isn't configured in xorg but I just configure it on the fly with 
 nvidia-settings in twin-view mode (the laptop panel at 60Hz and the hdmi 
 port at 50Hz).
 Provided that I disable Force Full GPU Scaling, the tv reports a 50Hz 
 signal.

if you disabled full gpu scaling , how upscaling will work really ? what and 
how will upscale SD video to 1080p ?

 This setting is only useful if your display device can't scale on its own or 
 the scaling is worse quality. If you enable it the card will always output 
 native resolution at native refresh.
 
 If disabled the gpu will not touch the mode and output whatever you tell it 
 to, in which case the display itself will have to scale the mode as needed.


let's have a look on the following situation.

I have full HD TV set, which of course can upscale. TV
My xorg.conf has default mode - 1080p

can be 2 situation

With vdr and vdr-xine I'm watching SD 576i channels and after that I switch to 
HD 1080i channel.

Does graphic card do upscale in first variant (with SD channel) ?
