    HDMI not working (Vista to 7 Upgrade)


    Recently I upgraded my vista to Windows 7 and tried connecting it to my HD TV through the HDMI but the screen on my laptop goes blank (black) and no reception on the TV as well. Have an ATI Radeon 4500 Series adapter and HDMI used to work perfectly in Vista. Please Help

    Hi there, Welcome to Seven Forums.

    Have you tried checking your display driver is installed? It may have been skipped due to the upgrade.

    Yes, it is installed (ATI Mobility Radeon HD 4500 Series). Have an Acer Aspire 5738Z...tried checking their drivers online but nothing about the HDMI

    Okay great. Have you tried checking the settings in the catalyst control center?
