I just changed over from a 6600 (running monitor + tv through svideo) to a TwinTech 8800GTS, and I cant seem to get both displays working.
When I first powered up the tv was working but monitor wasnt, at which point I realised the monitor wasnt plugged in lol.

Anyway plugged it in and rebooted, and lost the image from the TV. Ran the multiple display wizard, a picture flashed up on the TV then disappeared again, and only the monitor appears in the list of displays.

Could it be an inadequate power supply or some other issue?

[COLOR=“DarkGreen”]Have you check the display settings on display property settings.

Yeah, it only shows my monitor, doesnt show the TV.
When I run the multiple display wizard, a picture will show up on the TV for about 2 seconds, before it goes back to black again :frowning:

I don’t know about the 8-series drivers, but the 4,5,7 series drivers all have the option “Force TV detection” (using S-Video cable, of course).
