[edit] How to test HDMI

Check the devices (HDMI may be on display1 or 2 depending on whether you have DVI and which one it was assigned to)

 lcd=/sys/devices/platform/omapdss/display0
 hdmi=/sys/devices/platform/omapdss/display1

To enable HDMI

 echo "0" > $lcd/enabled
 echo "1" > $hdmi/enabled

To switch back to LCD from HDMI

 echo "1" > $lcd/enabled
 echo "0" > $hdmi/enabled

[edit] How to test HDMI in Android

 lcd=/sys/devices/platform/omapdss/display0
 hdmi=/sys/devices/platform/omapdss/display2
 echo "0" > /sys/devices/platform/omapdss/overlay0/enabled
 echo "0" > $lcd/enabled
 echo "hdmi" > /sys/devices/platform/omapdss/manager0/display
 echo "1" > $hdmi/enabled
 echo "1" > /sys/devices/platform/omapdss/overlay0/enabled

[edit] Known Limitations

• HDMI has been tested on Angstrom. A video clip that has audio can be played on TV. But the image is not full screen. This is being investigated.
