3.2 Obtaining an image on the screen
As shipped from the factory or after a factory default reset, the
unit output resolution setting
should be “NATIVE”. This means
that upon power-up the device will read the EDID of your display
and output a compatible resolution resulting in a picture.
However, if the output setting is not at “NATIVE”, or if the unit
cannot ascertain the EDID of the display, then you may not get a
picture. Since most settings are done by means of an on-screen
display (OSD), it is necessary to get an image on the display first.
For this purpose, you can use one of two preset button
combinations to set a resolution that your display supports. Two
options are available (depending on the display device):
1. If the display is HDTV compatible (with an
HDMI™
connection), then a resolution of 480p should result in an
image.
2. If the display is PC compatible (DVI), then XGA (1024x768)
should result an image.
Once you have an image, you can call up the OSD menu to
make further changes if necessary.
At any time, pressing the UP ARROW  and MENU button
together will change the output resolution to 1024x768 @ 60 Hz.
Pressing the MENU and DOWN ARROW  together will change
the output resolution to 480P @ 60 Hz.
3.3 Setting the output resolution
Press the MENU button to open the OSD and use the arrow
buttons () to select the OUTPUT option. Press the MENU
button.
Use arrows to scroll through the available resolutions listed. See
Section 5.1 below for a list of all available resolutions.
