Default monitor not working through DVI

[drunkenmunky]

I've just bought a new graphics card (GeForce 8800) which is connected to a 21" ViewSonic monitor. I wanted to try some games on my HDTV so I connected it to my TV via a DVI-VGA adapter. Since then I can no longer use my ViewSonic monitor, which is the deafult monitor. I get no signal. But the monitor does work through VGA.
It seems now that my HDTV is the default monitor so my question is, how do I get my graphics card to pick up the signal from my ViewSonic monitor again?

Please help, thanks
