If the image is out of focus:
❏
Be sure the lens cover is open.
❏
While displaying the on-screen menu, adjust the focus ring. (The image
size should not change; if it does, you are adjusting the zoom, not the
focus.)
❏
Ensure the projection screen is 1 to 10 m (3 to 33 ft) from the projector.
❏
Check the projection lens to see if it needs cleaning.
❏
For a computer connection, set the display resolution on the computer to
800×600 pixels. If the computer has multiple monitors, adjust the
resolution of the monitor assigned to the projector.
❏
For a computer connected to the S-video port, the picture cannot be as
high resolution as what you see on the computer display.
If the image is too small or too large:
❏
Adjust the zoom ring on top of the projector.
❏
Move the projector closer to or farther from the screen.
❏
On the projector or remote control, press the picture mode button one or
more times to see if one of the picture modes makes the image the correct
size.
❏
Press menu, go to Picture > Customize picture mode > Stretch. Try
the different settings.
❏
If the source device sends wide-screen output, press menu, go to Picture
> Shape settings, and try setting Widescreen input to Yes. Otherwise,
set it to No.
If the image has slanted sides:
❏
As much as possible, reposition the projector so that it is centered on the
screen and below the bottom of the screen.
❏
On the projector or remote control, press the keystone button until the
sides are vertical.
