Windows 7: resolution change after rebooting or wake up from sleep

resolution change after rebooting or wake up from sleep

Hi all,

The screen resolution of my Win7 HTPC keeps changing from the chosen 1200 x 720 to the lowest 800x600 after restarts or after waking up from sleep mode

The odd thing is that it does not happen each time. I have tried to reproduce the problem by powering on the devices at different order, but I cannot find any logic.

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

Do you know how can I prevent this to happen?

Try downloading and updating your VGA Drivers. Uninstall the current version first than install the most recent one hope it will help. Also download this version of DirectX 9 and install it.
Download details: DirectX End-User Runtimes (June 2010)

Sorry, I forgot to say I am connecting TV to PC using an HDMI connection . So VGA won't have an effect
