Does it display in SAFE MODE?
Did you set the resolution and refresh manually in SAFE MODE then shut down proper?

I have recently update to windows 7.
So as you do i installed my Graphics card, a VTX Radeon 5450 HD via the official website and did a update.
After a reboot my current monitor was displaying a blank screen with 'unsupported' across it.
So i switched to my TV to see if that would work, it did, but started to constantly change resolutions while i was using it.
Imagine every 5-10 seconds the screen going blank and a new resolution appearing.
I have attempted a reinstall, while patiently navigating through the changing screen i checked to see if everything was in order and it was showing as installed and properly functional. I then tried another windows update and that was in order.
I have currently uninstalled it and the pc is showing 'standard VGA graphics adapter'. I know the graphics card works with my system as it has been running fine with my windows xp.
If any help to what the problem may be can be given i would be most thankful.
