Main monitor blank when connecting TV.

[Severen]

Greetings guys and girls!
Yet another dual screen problem.

Setup:
nVidia 9800GT, 196.21 drivers.
W7-64 Ultimate.

Problem:
Trying to hook up the TV to the comp.
After doing so and clicking to identify all connected screens, main screen goes black.
Message of resolution being out of range appears. Same if I try booting with TV connected.

The TV gets signal but wrong resolution.
Only way to get rid of it is disconnecting the TV and rebooting.
Main monitor comes back as normal.

I've tried setting different resolutions in the nVidia tool, but it isn't helping much.
Read somewhere about a similar problem where the added external screen recieves a refresh rate of 85, sounds like it could be something like that. Any thoughts would be helpful.

Problem is really to just make the computer recognize the TV without blanking the main monitor.
Tired of watching series on this old 19"..

Thanks in advance!

Solution

Seems as if it was what I suspected, wrong setting on the screen.
Managed to change the resolution on the screen and I could begin toying around with the TV.

After some really weird setting back and forth I got it working.
Something tells me though that nVidia's little control panel is somewhat *ucked.
It wouldn't take standard setting for TV until I lost the main monitor and got it back again.

ATi is looking good next time around..
Cheers!
