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.
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.
The display appears compressed ...
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.
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. It's 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. Try Auto Setup.
2. The color, tint, color space, color temperature and/or other settings may require
adjustment.
3. Ensure signal connections are correct.
4. Ensure the proper channel for this source is being used.
Values in Color Saturation slide bars vary over time...
1. Once defined, Color Saturation slide bar values fluctuate over time and will likely
be different upon subsequent visits to this menu. This is normal and should be
ignored, as these changes do not redefine the x/y coordinates or color gamut.
The display is not rectangular...
1. Check leveling of the projector. Ensure the lens surface and screen are as parallel
to each other as possible.
2. Is the vertical offset correct? Adjust as necessary using the vertical offset knob.
