- Your frequency and tracking need to be adjusted. Always adjust frequency
first. Go to the Windows shutdown screen. This optional step will make
it easier to adjust frequency and tracking, but is not necessary.
a. Shut down all applications (Word, Excel, PowerPoint).
b. Click the "Start" button. Go to "Shut Down."
c. Do not hit OK, do not shut down the computer. The background of the
shutdown screen will be slightly dark, and show any problems with frequency
and tracking. When completely finished adjusting frequency and tracking,
click "Cancel" and the computer will go back to Windows.
- Adjust Frequency. Problems with frequency will display dark vertical
bands or shaded areas. The goal is to eliminate variations across the
screen. The entire screen should look consistent, even if it looks consistently
bad. Press the Menu button on the projector or remote.
a. Use the directional arrows to highlight "Frequency."
b. Press the Enter button. The Frequency dialog box will pop up.
c. Use the directional arrows to move the frequency value. Go whichever
direction reduces the number of dark bands. The bands become wider and
fewer in number. If more, thinner bands appear, go the opposite direction.
d. Adjust until all bands or unevenness are gone. Be aware: When one
band is left and it is adjusted off, the entire screen might go crazy.
This is acceptable. The goal is to get the whole screen consistent,
even if it is consistently bad.
- Adjust Tracking. Tracking on the Lightware projector is similar to
tracking on old VCRs. It removes the last remains of screen jitter,
jump, horizontal lines moving through pictures, or the appearance of
characters dancing or waving.
a. Press the Menu button on the projector or remote.
b. Use the directional arrows to highlight "Tracking."
c. Press Enter. The Tracking dialog box will pop up.
d. Use the directional arrows to sweep tracking values all the way from
one side to the other. There may be several places that look good. Try
them all. In some spots, it will look worse before it looks better.
