Steady flickering or several soft vertical stripes or bands across the entire image
indicates poor pixel tracking. Proper pixel tracking helps ensure that the image quality
is consistent across the screen, that aspect ratio is maintained and that pixel phase
(see above) can be optimized.
• Sync Level (Component sources only): Select Sync Level to adjust the voltage level
of the Q-750i Sync signal detection circuitry.
Sync Level adjustment is occasionally necessary when a DVD player or HDTV source
signal drops “below black” (for example, during scenes with explosions or when
subtitles are present) and causes the projector to temporarily lose sync. If the Sync
Level from the source is persistently too low, the projector won’t sync with the source
at all.
The range is from 50 to 256 millivolts (mV) inclusive. The default setting is 240 mV and
should rarely require adjustment.
PCE: To use the Personal Color Equalizer to define a custom color gamut, choose the
“PCE” Color Gamut setting (refer to Color Gamut on page 57). Then, choose PCE from
the Advanced menu and press ENTER. This displays the PCE sub-menu, shown in Figure
4-11.
