.
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. Make sure you are using the proper channel for this source.
Values in Color Saturation slidebars vary over time…
1. Once defined, Color Saturation slidebar 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. Make sure that 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.
