When using a video software program (such as a cinema
size program) with a screen wider than one in the 16:9
mode, blank areas separate from the images are formed at
the top and bottom of the screen.
Even when the temperature of parts of the front, top and
rear panels has risen, these temperature rises will not pose
any problems in terms of performance or quality.
When HDMI or DVI signals are input to the Display using a
selector or distributor, sound or images may not be output in
the normal fashion depending on the selector or distributor
used.
The symptoms may be improved by turning the power off
and on again, or by replacing the selector or distributor.
Check that the connection has been made properly.
