(7) Screen size adjustment
a. Screen size
Screen sizes are set through adjustments of HEIGHT and
WIDTH. For these two pieces of data, the following four types
(three types for HDTV) of size settings are available in a single
signal format. Also, there is individual data for files that can
be input to the following types.
• U-SCAN switch
NORMAL SCAN, UNDER SCAN
• ASPECT switch
4:3 SCAN, 16:9 SCAN
b. Caution
For HEIGHT or WIDTH adjustments, separate data is stored
in each signal format. Do not perform the switching below
during data change.
• Channel switching
• Input signal format change
• SCAN switching
• ASPECT switching
If any switching above is done, data in a format different from
the currently set one will be invoked and the data that is being
changed will be cleared. When HEIGHT or WIDTH data is
being changed, therefore, take care not to perform any switching
above before the changed data is registered.
The following adjustment steps are for a certain signal format.
Other formats can also be set in the same manner. Prior to this
adjustment, make the adjustments in (6) and (7).
