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.
3. Make sure you are not using the cinema processing path on the CP2000.
4. If the image is cropped Left/Right, you may be exceeding the current bandwidth
limitations of the processing chip. Reduce the re-size settings or (if possible)
reduce the incoming signal’s vertical frame rate.
5. If the image is cropped top/bottom, you may have exceeding the vertical frame
rate limitations for the DVI port on the
CP2000 . If possible, reduce re-size
setting to fit within the cropping area or reduce the vertical frame rate of the
incoming signal on the
Cine-IPM 2K input. Make sure you are not using the
cinema processing path on the CP2000.
6. Check the TPC setting to ensure source and screen are set to 2048 x 1080, or
Auto Square pixels.
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/or
Cine-IPM 2k 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. Make sure to use the proper TPC settings—color space on the CP2000 should be
an RGB format, with gamma set to Gamma 2.6.
3. Make sure you are using the proper channel for this source.
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. Ensure “Keystone” is set correctly.
3. Is the vertical offset correct? Adjust as necessary using the vertical offset knob.
