Changing Display Configurations
Starting your Mac with Mac2TV enabled
If you have Mac2TV display enabled when you shut
down, the next time you startup your TV is your display.
If you shut down with Mac2TV enabled, and remove the
connection to the TV, the next time you startup the ATI
software switches the video signal to your computer
monitor.
Using a TV as your only display
If you are using television display only, disconnect your
monitor from your XCLAIM VR card. XCLAIM VR
detects that you have a TV attached and automatically
starts with Mac2TV display enabled.
Optimizing Mac2TV
You can optimize your TV display using the video out
preferences. Viewing images on your TV can be improved
by changing the contrast, brightness, or size of your
display.
