If you are not getting any image on your display, it could be that the
output resolution setting of the AC139A is not supported by your LCD.
Using serial commands or the IR remote, one can quickly switch between
various output resolutions. However since the front panel operation relies
on OSD menu for navigation, it is very difficult to change the output
setting from the front panel if you cannot see the OSD. Therefore to
quickly jump to a basic resolution that is supported by virtually all
displays, is a great feature.
If you press and hold down the MENU button, and then hit the ▲ button
you get a XGA output which is supported by most PC compatible
displays.
If you press and hold down the MENU button, and then hit the ▼ button
you get a 480p output which is supported by most HDTV compatible
displays.
