Resolution
1. The frequency of the pixel sampling clock is incorrect for the current source.
2. Sizing and positioning options may be adjusted poorly for the incoming source signal.
3. Use an anamorphic lens for typical HDTV and anamorphic DVD sources that have been re-sized
and vertically stretched, through 3rd-party software.
Data is cropped from the edges
Parts of the image are missing at the edges of the display.
Resolution
• To display the missing material, reduce image size to fill the display area available in the
projector, then stretch vertically to fill the screen from top to bottom.
• Add the anamorphic lens to regain image width.
Display quality appears to drift from good to bad,
bad to good
The quality of the input is inconsistent.
Resolution
• The source input signal may be of low quality.
• The horizontal or vertical frequency of the input may have changed at the source end.
Display suddenly freezes
The image stops playing, and freezes.
Resolution
If the screen blacks out inexplicably, it is possible that excessive voltage noise on the AC or ground
input has interrupted the projector’s ability to lock on to a signal.
• Power down the projector and disconnect from AC.
• Then plug in again and power up as usual.
