first time poster, long time reader.....

So I've searched and searched for a solution but havent had any luck, but this is what happens.

I'm switching from Mythbuntu to Win 7 Media center, just for something to do.
However, when I put MC into fullscreen, the screen goes black, if I move the mouse, I can see the curser, but the MC menu is not visible.  if I 'alt+tab' I can see the MC menu in the background, but as soon as I focus on it, the screen goes black again.
This only happens in 1920x1080 60hz in fullscreen mode
i.e 1280x720 60hz works fine in fullscreen, and 1920x1080 60hz works fine when 'windowed'

Oddly enough, win7 itself is using this resolution and refresh rate just fine! (it is what the TV manual recommends!!)

TV is a sony 46" W series (KDL-46w5500)
PC is an Asus pundit so has a geforce 6150
I'm connecting the PC to the TV with a VGA cable.

Anyone able to help/shed any light on this

Sounds like you running out of Video Memory - at least thats my guess.

If your using onboard video make sure you've got the video memory in the bios set to whatever the maximum it can be ie 256MB or whatever. The usual defaults are only 64MB or something like that.

Media Center uses its own display in addition to the desktop - so your trying to run 2 x 1920x1080 screens in effect. This needs lots of video ram.

BTW - A 6150 chipset is gonna struggle to play clean video at 1080p.
