dual monitor help

Hey,

I used to rock Dual monitors all the time a while back and it was easy as hell but ever since I bought a new tv and switched to w7 (same time) I cant seem to get dual monitors to work anymore.

I don't know what causes it, each screen works fine individually, and if I have my monitor plugged in and then plug in my tv and scan for new displays my tv takes over and the monitor becomes blank.
So I can't have both displays running at once anymore and it just refuses to recognise both.

My tv is hooked up with a vga cable and my monitor is hooked up via HDMI, is this the problem?

Any help would be appreciated.

Hook up both, right click on your desktop and go to screen resolution. What does it say there? You should be able to config it properly once both devices are connected and you're at that screen.

I have a monitor and TV hooked up as well, but my TV is DVI to HDMI, not straight HDMI.
