The display is jittery or unstable...
1. If the non-cinema display is jittery or blinking erratically, ensure that the source
is properly connected and of adequate quality for detection. With a poor quality
or improperly connected source, the projector will repeatedly attempt to display
an image, however briefly.
2. The horizontal or vertical scan frequency of the input signal may be out of range
for the projector. Refer to Section 8, Specifications for scan frequency ranges.
3. The sync signal may be inadequate. Correct the source problem.
The display is faint...
1. Brightness and/or contrast may be set too low.
2. The source may be double terminated. Ensure the source is terminated only once.
3. The source (if non-video) may need sync tip clamping.
The upper portion of the display is waving, tearing or jittering...
1. This can sometimes occur with video or VCR sources. Check your source.
Portions of the display are cut off or wrap to the opposite edge...
1. Resizing may need adjustment. Adjust until entire image is visible and centered.
The display appears compressed (vertically stretched)...
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 via 3
Data is cropped from edges
1. 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 the image width.
Display quality appears to drift from good to bad, bad to good...
1. The source input signal may be of low quality.
2. The H or V frequency of the input may have changed at the source end.
The display has suddenly froze ...
1. 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 (see 3.3, Power-down Procedure) and unplug.
Then plug in again and power up as usual (see 3.2, Power-up Procedure).
Colors in the display are inaccurate...
1. The color, tint, color space and/or color temperature settings may require
adjustment at your input source.
2. Make sure you are using the proper PCF, TCGD and/or CSC file for this source.
