     • Earlier versions of set-top box firmware didn't properly handle automatic HDMI connections. You may need an update to your set-top box firmware, or a newer set-top box from your service provider.

     • Set the appropriate HDMI properties .
     • You'll need a separate audio connection when your computer recognizes the HDMI connection as a DVI connection .
