Windows 7 Bootcamp External Display woe's!

[Markf11]

Can anyone help me. I've tried re-installing and updating every possible graphics related driver for Windows 7 i cannot for love or toffee get the bloody thing to even recognize my display.
I am using a 26" tv as an external display, it works on OS X (very easily), windows XP (also very easily) and even Vista (also easily) and connecting through a DVI/HDMI connector.
. Why not windows 7? I've scoured the web for answers but can't find anything. Is anyone at least in the same boat as me? I really need this solved soon
Thanks for any suggestions

I'm having exactly the same problem... The weird thing is that it works when I connect it to a monitor (using DVI)... When I go to the TV also using DVI, I just have a black screen!

I'm getting fed up =/
