DirecTV H23 User Manual page 85

If your TV supports all formats (1080i, 720p, 480i and 480p), then your cycle would also include 720p.
If Native is turned on, the FORMAT key cycles through Stretch, Letter and Crop for the current TV
program's native resolution. Th e FORMAT key allows you to easily cycle all resolution and format
settings with a single key until the picture displays the way you like it. Navigating menus to modify
settings is not necessary.
If pressing this key causes a loss of video and audio, continue to press it until the picture returns. (Wait
a second between presses to allow the Receiver to change the resolution.) Th is can happen if your
settings include a resolution that your TV doesn't support. To correct this, you'll need to change your
resolution setting: Press MENU, select Help & Settings, then Setup, then TV Type in the left side menu.
Press SELECT on the Resolution tab and mark or unmark the TV Resolutions to display the resolutions
supported by your television.
RESOLUTION Key on Receiver Front Panel
Th is key is used to cycle all available resolutions on your DIRECTV HD Receiver. It does not cycle
format settings. If video and audio are not appearing, it may be because the current resolution setting
is not supported by your television. By pressing this key, you can check all available resolutions to see if
that solves the problem. Th e lights next to the RESOLUTION key on the front panel will light above
the resolution to which the receiver is set; they will change with each key press.
