    Hi MAPM14,

    The resources below will explain how to set up and troubleshoot the connection between your HDMI TV and your MacBook Air.  

    Get help with video issues on external displays connected to your Mac

    If the display image is blank or unusable

    Try these steps if you don't see an image on your display. These steps can also help if the image on your screen repeatedly turns on and off (flickers), if horizontal lines appear (snow), or if the image is distorted (torn or scrambled). 

    These steps likely won't help if the issue is only happening in one app. If you see similar issues in only one window or app, check with the app's developer for updates or more help.

    Check connections

    Check the connections to your Mac and external displays:

    • If you're using an Apple notebook, try connecting its power adapter.
    • Make sure the external display's power cable is securely connected and that your display is turned on.
    • If you're using a Mac Pro (Late 2013) make sure your displays are connected to the right ports.
    • If you're using a display hub, switchbox, or "KVM," try connecting your display's video cable directly to your Mac instead.
    • Disconnect the video cable where it plugs into your Mac, then plug it back in to reseat the connection.
    • If you're using a video adapter, unplug the video adapter from your Mac, then plug it back in to reseat the connection.
    • If you're using more than one video adapter to connect your display (the adapters are "chained" together), try connecting the display using only one adapter if possible. Some video adapters can't be connected together. For example, a mini DisplayPort to DVI adapter can't be connected to a DVI to HDMI adapter.
    • If your display has more than one video connection, see if using another connection on the display works. If possible, check to see if using a different display or a different adapter works.
    • Try using a different cable that you know is in working order. Check with the display's manufacturer to make sure you're using the cable they recommend.

    Take care,
