    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?

    Thanks

    pj

    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.

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

    cheers
