- Aspect ratio depends on both the incoming program format and the
Display Format button on the front panel. Once the button for the format is
set to a standard definition (480i/480p) and the incoming program is set at
a 4:3 video, the aspect ratio can not be adjusted and a warning message
will appear on the screen. (see section 8-12)
- Similar to the above case, once the button for a format is set to high
definition (720p/1080i) and an incoming program is set at a 16:9 video, the
aspect ratio can not be adjusted and a warning message will appear on the
screen.
- Make sure the batteries are fresh and installed properly. (see section 8-9)
