I use a sapphire radeon in an HTPC DVI->HDMI connected to sony bravia full-HDTV.
If I switch the TV to another source (example xbox360 on component) and directly back then DVI signal is gone; all's black.
If I then force the videocard to renew its signal (fullscreen dos and back) i have windows back on tv.

Since it is a HTPC i want to use it through remote, so I don't care what silly workaround I have to do to resolve this silly problem as long as it can be done through my pronto universal remote control. It might be some utility that I start with a windows hotkey that just only revives the signal from the videocard. I am a delphi programmer so if someone could inform me what code might suggest the videocard to end it's strike I's be much obliged too.

Thanks

its probably some HDCP crap, are you in vista?

Nope, WinXP Prof..

Meanwhile I created the workaround with silliness factor 10+ I was looking for
Old airboard keyboard remote IR receiver gets two keyboard commands from my pronto remote. One says 'alt-tab' (to get out of XBMC, the software I use in my HTPC), the other is just the defined keystroke for a shortcut to a batchfile, which just says ECHO HELLO at full screen and exits.

Meanwhile I found my problem is not unique:

Also it shows someone else who couldn't find another way out but with homebrew 'software'

I don't want to kick anyone against the toes, but I do get the idea that NVIDIA has it's business a bit better on order than ATI. Beside this little issue i find it a bit strange that if I connect the card to a 1080 screen and I tell windows to go to 1920x1080 I expect a pixel perfect image. In stead I got an image covering 80% of the screen with interpolated ugliness and I had to fiddle with some overscan slider to get it right..
