
The display is jittery or unstable...
1. If the 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 6, 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 very low.
2. The source may be double terminated. Ensure the source is terminated only once.
3. The source (if non-video) may need a different sync tip clamp location.

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 and/or blanking may need adjustment.

The display appears compressed (vertically stretched)...
1. The frequency of the pixel-sampling clock is incorrect for the current source.
2. Resizing, vertical stretch and positioning options may be improperly adjusted for
the incoming source signal.
3. You may need an anamorphic lens for sources that have been supplied in a re-
sized and vertically stretched format.

Data is cropped from edges
1. Check settings for Blanking.
2. If incoming data is still missing from the image, reduce the image size to within
the display area available in the projector.

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 frozen...
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 and disconnect from AC. Then plug in again
and power up as usual.

Colors in the display are inaccurate...
1. The color, tint, color space, color temperature and/or other settings may require
adjustment.
2. Ensure the proper channel for this source is being used.
