A Video Mode (pg. 333)
Be sure that the video standard matches the standard used in the video
device. Note that resolution will drop when images are output on a PAL
device.
A Television Playback
Use of an EH-5a or EH-5 AC adapter (available separately) is recommended
for extended playback. When the EH-5a or EH-5 is connected, the camera
monitor-off delay will be fixed at ten minutes and the exposure meters
will no longer turn off automatically. Note that the edges may not be
visible when photographs are viewed on a television screen.
A Slide Shows
The Slide show option in the playback menu can be used for automated
playback (pg. 266).
