Windows 7: screen resolution changes after PC wakes up from sleep

screen resolution changes after PC wakes up from sleep

hi all
I am running a Windows 7 HTPC, which connects to an LCD TV. Unfortunately, I keep getting automatic screen resolution and aspect ratio changes all the time.

Each time I start the PC from from a complete powered off state, I have to go to the TV settings and change the aspect ratio.
Many times, not each time, when I wake up the PC from from a sleep state, the resolution of the screen changes automatically from 1200 x 720 to the lowest 800x600

PC connected to LCD TV 32'' Sansung
Onboard Intel GMA X4500 Graphics card with latest drivers


I am using the latest drivers that i know. Any idea of how to stop that to happen?

Thanks

I think that the resolution change might be related to the order in which the TV and the PC go to sleep and wake up...
...However I still cannot find any logic...

Any help would be fantastic

cheers
