Q: Why can I not see DIRECTV menus and screens on my
TV? OR
Why do I see a message that says, "This TV or its cables
are not HD. To see screen graphics, press the RES key
on the front of the receiver until this message no longer
appears".
When the receiver resolution is set to 720p, 1080i, or 1080p, DIRECTV
screens and menus ("user interface") will not appear on Standard
Definition (SD) outputs. A message is displayed to notify you that the
resolution setting needs to be changed.
Possible Causes:
You have connected your receiver to your TV using both a High Definition output (HDMI) and Standard Definition (SD) outputs
(S-Video, Component (Red/Yellow/White), or Coaxial) on the same receiver.
You are using SD outputs (S-Video, Component (Red/Yellow/White), or Coaxial) and have the receiver set to HD resolutions
such as, 720p, 1080i or 1080p.
Solutions:
Change the receiver resolution to 480i or 480p by pressing the RES button on the front receiver panel until 480i or 480p is selected.
Uncheck all resolutions except 480i or 480p on the TV Resolutions menu. Press MENU, select "Settings", "HDTV" and then
"TV Resolutions". Follow the onscreen instructions.
Turn "Native" Off. Press MENU, select "Settings", "HDTV", "Video", then "Native", and follow the onscreen instructions.
