disappearing display?

[nightmare]

I am using a e-geforce 6200 video card. on the vga port I am using a standard crt monitor. I have my Phillips 42" LCD T.V. on the DVI port via HDMI. If both of my displays on physically on when I boot my system, all works great. However, if I power down my Phillips T.V. Windows adjusts the video, and I cant get it to see it again. The only way to get a picture on my Phillips is to reboot again with the T.V. powered on. Is there anyway to make Windows see the display without a reboot?

Have you disabled any services, particularly anything to do with Tablet PC functions?

In Vista, for example, there was a TMM item related to Tablet-PC services (or dependent upon it) that ran as a scheduler item always monitoring for new monitors being added to the equation - if that gets disabled in any way then you'll lose the ability to find the monitor when you power it back on....
