• Tracking (RGB or Component sources): Tracking determines the frequency of the pixel sampling clock, indicated by
the number of incoming pixels per line, so that all pixels generated by a particular source are sampled.
• 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 main-
tained and that pixel phase (see above) can be optimized.
• Sync Level (Component sources only): Select Sync Level to adjust the voltage level of the Projector Sync signal de-
tection 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.
System
Use the controls in the System menu, shown in Figure 4-11, to adjust the lamp, change the display orientation and
perform other, common installation tasks.
