HIGH-DEFINITION
SCREEN FORMAT & RESOLUTION
In addition to resolution and interlacing, a television picture is also defined by its aspect ratio- referring to the shape of the
screen as defined by the ratio of the screen's width to its height. For analog TV, the aspect ratio is 4 units wide by 3 units high
(4:3). This is the familiar shape of conventional Tvs-slightly wider than they are tall. SDTV and EDTV pictures can be either 4:3
or 16:9. For HDTV broadcasts, the aspect ratio 16:9-nearly twice as wide as it is tall. this is, not coincidentally, more like the
shape of movies shown in theaters,which makes HD an ideal format for viewing movies on TV. You will be able to see much of
what is captured on film, but lost on an SDTV display.
In order to optimize the display of programs on your television, you may occasionally need to change the resolution and/
or screen format. There are two keys that can be used to make changes: the FORMAT key on the remote control and RES
(Resolution) key on the front panel of the DIRETV HD Reciver. To change your Screen Format, TV Ratio, or TV Resolution
settings, press MENU, select "Settings & Help", then "Settings" , then HDTV.
FORMAT KEY ON REMOTE CONTROL
Press the FORMAT key on your remote control to cycle throught the resoluction supported by your
TV, as well as, the screen formats in conjunction with each individual resolution. Available screen
formats such as crop, stretch or letter/pillar box, are based on the TV Ratio setting. With each
press, an onscreen message will let you know what the current resolution/format setting is.
For Example, if you indicated that you TV supports only 1080i, 480i and 480p and it is a 16:9
television, and Native is turned off*, the cycle of settings for the FORMAT key are as follows:

*NOTE: In Native mode, the receiver automatically adjusts resolutions to match the resolutions of individual TV programs as
they are turned.
If Native is turned on, the FORMAT key cycles through Stretch, Letter and Crop for the current TV Program's native resolution. The
FORMAT keys allows you to easily cycle all resolution and format settings with a single key until the picture displays the way you
like it. 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.) This can happen if your settings include a resolution that your TV dosen't
support. To correct this, you'll need to change your resolution setting: Press MENU, select "select "Settings & Help", "Settings,"
"HDTV" and then select "TV Resolutions." Mark or unmark the TV Resolutions to display the resolutions supported by your television.
