Please Note:

Not all broadcasts are in High Definition (HD). Please refer to your local broadcasting
stations for more information.

The HD Display
’s tuner is designed for HD Display therefore requires a stronger
signal than normal Displays. If you cannot achieve that signal level with your antenna
or cable
, your HD Display might lose picture or sound.

HDMI 1 doubles as a MHL enabled port, so if you have a cell phone that
supports the Mobile High-definition Link, you can purchase a MHL cable and
connect it to HDMI 1.

HDMI1 supports MHL devices such as ROKU MHL streaming stick device.
