Your Image Has a Vertical Flickering Bar
If the projector displays a vertical flickering bar, you may have different frequency
settings set on your input source.
IMPORTANT
Write down your setting values before adjusting any of the settings in the following
procedure.
1. Adjust the Frequency setting in the on-screen display. See page 24.
2. Check the display mode of your computer's graphics card. Make sure it matches
one of the projector's compatible signal formats (see page 34). Refer to your
computer's manual for more information.
3. Configure the display mode of your computer's graphics card to make it
compatible with the projector. Refer to your computer's manual for more
information.
4. Optionally, reset the projector as described on page 76 to adjust your frequency
to its original value.
IMPORTANT
This action resets all values to their defaults.
Unaligned Projected Image
Like all mechanical systems, the SMART UF65 or SMART UF65w projector's image
may slip if it is moved often or installed in a location prone to vibration (such as next to
a heavy door). Follow these precautions to help prevent the image from becoming
misaligned:
• Make sure that the installation wall is plumb, square and doesn't move or vibrate
excessively.
• Make sure that there are no obstructions behind the projector's wall mount
bracket, and that it's firmly secured to the wall according to the installation
instructions.
• Make sure that the wingnut on the top of the projector's ball joint is tight.
• Confirm that all cables are held in place with the appropriate cable clip.
• Adjust the projected image. See the included
