So please DO NOT use VGA output mode if you
desire high definition resolution output (720p &
up).
*To prevent accidental changes to HD resolutions
your TV does not support, you will be prompted if
you would like to save the selected resolution and
use it after the player has been reboot. The
resolution will be reset to 480p standard video
output if you opted not to save.
Simply turn the player off and power back on and
wait for 10~15 seconds if you accidentally
changed your video resolution setting causing no
video to appear on your TV. The resolution will be
reset to 480p standard video output.
