Fixing Problems
If the image is out of focus:
Be sure the lens cap is removed.
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 1.2 to 12 m (4 to 40 ft) from the
projector.
For a computer connection, set the display resolution on the
computer to 1024 x 768 pixels.
Check the projection lens to see if it needs cleaning.
If an upside-down or reversed image is displayed:
The projector has been set to the wrong position setting. Open the
on-screen menu, select Setup > Projector position, and select
the correct setting.
If the image is too small or too large:
Adjust the zoom ring on top of the projector.
Be sure the projector is 1.2 to 12 m (4 to 40 ft) from the
projection screen.
Open the on-screen menu and select Adjust picture > Aspect
ratio. Set to Best Fit or Fill. For a wide-screen picture, try setting
the aspect ratio to 16:9.
If the image has slanted edges:
As much as possible, reposition the projector so that it is centered
on the screen and below the bottom or above the top of the screen.
The projector can automatically correct slanted sides of the
picture when the projector is tilted up or down. However,
additional corrections might be required in certain situations.
Open the on-screen menu and select Adjust picture > Keystone
correction. Adjust the horizontal and vertical settings as needed
or enable or disable the auto keystone correction.
