Displays

3.7.1 The Projector is ON, but No Display

• Make sure the lens cover is removed from the lens.
• Make sure the correct display button is selected in the channel setups.
• Make sure AC power is connected.
• Check the cable connections and make sure that the active source is selected.
• Make sure that the DVI cable from the PHM to the EM is connected.
• Are the test patterns accessible? If so, check source connections again.

3.7.2 The Display is Jittery or Unstable

• If the display is jittery or blinking erratically, make sure that the source is properly connected and of adequate
quality for detection. With a poor quality or improperly connected source, the projector repeatedly tries to
display an image, however briefly.
• The horizontal or vertical scan frequency of the input signal may be out of range for the projector.
• The sync signal may be inadequate. Correct the source problem.

3.7.3 The Display is Faint

• The source may be double-terminated. Make sure that the source is terminated only once.
• The source (if non-video) may need sync tip clamping.
• Check RGB Brightness setting and Brightness Uniformity control.
• If the ChristieTWIST™ software was used, test by disabling the blend.

3.7.4 The Upper Portion of the Display is Wavy, Tearing or Jittery

• Check your source (this can occur with video or VCR sources).
• Check that the RGB Brightness setting is not unexpectedly low.

3.7.5 Portions of the Display are Cut Off or Warped to the Opposite edge

Resizing may need adjustment. Adjust until the entire image is visible and centered.

3.7.6 Display Appears Compressed (Vertically Stretched)

• The frequency of the pixel sampling clock is incorrect for the current source.
• Sizing and positioning options may be adjusted poorly for the incoming source signal.
• Check the geometry correction for warp or keystone correction.

3.7.7 Data is Cropped from Edges

• 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 image width.
• Check blend settings and masking.
