Only part of the computer image is displayed.
■
If you’re projecting from a computer or RGB video device, press
the
Enter/Auto
button on the remote control. If this doesn’t
work, you may need to adjust the
Position
setting in the Signal
menu. See page 55 for more information.
■
If you’ve enlarged part of the image using the
E-Zoom
button on
the remote control, press the
Esc
button to cancel zooming and
return to full display.
■
Try pressing the
Aspect
button on the remote control to select a
different aspect ratio (4:3, 16:9, or another available setting).
■
Make sure your computer’s resolution setting is correct and dual
display is not activated. Ideally, it should be 1024 × 768 to match
the projector’s native resolution. If this option isn’t available,
select another compatible video format. See page 107.
■
Windows
:
Right-click the desktop, select
Properties
, click the
Settings
tab, and select a different resolution.
■
Macintosh OS X:
On the Apple menu, choose
System Preferences
, then
click
Display
or
Displays
. Select a different resolution.
■
You also may need to modify existing presentation files if you
created them for a different resolution. See your software
documentation for specific information.
The image isn’t rectangular, but trapezoid-shaped.
■
Make sure the projector isn’t placed off to one side of the screen,
at an angle, or the image won’t be rectangular. Place it directly in
front of the center of the screen, facing the screen squarely.
■
If you’ve tilted the projector upward, the image will be broader at
the top. Turn on
Auto Keystone
as described on page 56 or hold
down the
or
buttons on top of the projector until the
image is rectangular.
