Changing the Display Size (Horizontal Amplitude and Ver-
tical Amplitude)
The projector already stores the standard personal computer and work station
resolutions in standard memory. When an RGB signal is input, the closest
resolution is selected from among those stored and the signal is displayed.
(When the information is stored in the user memory, it is searched from the
user memory.) It is for this reason that when the scanning frequency differs
from the value of the standard memory, the display area or aspect ratio will
also differ. The horizontal magnification and vertical magnification are used to
adjust this.
¥ Adjusting the Horizontal Amplitude
This function adjusts the horizontal display size to suit the screen.
Select [Alignment] ® [H Amplitude] from the main menu.
When the item to be adjusted is selected, the adjustment value of the selected
item is displayed at the bottom edge of the display.
Adjust the horizontal amplitude with the cursor § (Ð)/ © (+) button.
The adjustment range will differ depending on the input signal.
Holding down the button will result in a continuous change. Fine adjustments
can be made by single presses of the button.
¥ Adjusting the Vertical Amplitude
This function adjusts the vertical display size to suit the screen.
Select [Alignment] ® [V Amplitude] from the main menu.
When the item to be adjusted is selected, the adjustment value of the selected
item is displayed at the bottom edge of the display.
Adjust the vertical amplitude with the cursor § (Ð)/ © (+) button.
The adjustment range will differ depending on the input signal.
Holding down the button will result in a continuous change. Fine adjustments
can be made by single presses of the button.
Change the horizontal or the vertical amplitude when the aspect ratio of the
screen differs from normal (i.e., a circle has become and ellipse).

USING USER MEMORY AND
CHANNEL MEMORY (Memory)
Before Using the Memory Function
The projector uses a microprocessor to automatically iden-
tify the input signal. Therefore, it is necessary to set and store
in the microprocessor the adjustment conditions of such set-
tings as the alignments and picture settings that match the
input signal and that an optimum picture can be reproduced.
The projector is equipped with five kinds of memory. There
is standard memory that cannot be overwritten, user memory
to which the user can freely write or overwrite (and to which
switcher channels can be registered), special switcher chan-
nel memory that is used when this main unit and a number of
switchers are connected and used together , the default area
in a one-to-one correspondence with areas of the standard
memory, and last memory that stores the latest settings for
each source (RGB1, RGB2, Video, and S-Video)
Types of Memory
¥ Standard Memory (Preset at Time of Shipping)
Video signals of the type used in personal computers and
work stations currently on the market have been registered in
the projector as standard data (and cannot be overwritten).
See Displayable Video Signals on Page E-82.
When displaying personal computer video signals (resolu-
tion/frequency) that have not been registered to standard
memory, make the screen and picture adjustments and then
register them to user memory.
¥ User Memory
When data that has been adjusted by the user is stored to user
memory, it can be called back and used at any time.
A maximum of 100 items of screen and/or picture adjustment
or setting data can be registered.
¥ Channel Memory
This special memory for switchers is used to simultaneously
register the screen adjustment data and the data of the
switcher when the projector is used in conjunction with a
switcher.
A maximum of 100 channels (10 per switcher with max. of
10 switchers) of setting data (for the various pieces of equip-
ment that are connected to the switchers) and the screen and
picture adjustment data (adjusted by the projector) can be
registered.¥ Default Area
This is a rewritable memory that is in a one-to-one corre-
spondence with areas of the standard memory.
The projector searches the settings in the default area before
the standard memory.
The factory shipped default area settings are the same as in
the standard memory.
¥ Last Memory
This is a memory that stores the last settings for each source
(RGB1, RGB2, Video, and S-Video).
Switching sources will store the settings in memory. For this
reason, even if the memory is not used, returning to its
original source will store the adjustments in memory.
Automatic Searches of Memory
The channel memory is searched first when used with the
switcher (s).
When the input is switched, the projector searches the user
memory for the existence of applicable registration memory
during input selection (of input source) or switcher slot selec-
tion (RGB and RGB2 only). When more than one such
memory item appear, the most recent memory number is
selected. When there is no such memory item, the unit
searches irrespective of input selection or slot selection.
When there is no applicable memory item in user memory,
the default area and a standard memory search is performed
in this order (but there will not be a search when there is a
skip setting).
