Fixing problems

If the image is stretched:

❏ On the projector or remote control, press the picture mode button one or

more times to see if one of the picture modes makes the image the correct
size.

❏ Press menu, go to Picture > Customize picture mode > Stretch. Try

the different settings.

❏ If the source device sends wide-screen output, press menu, go to Picture

> Shape settings, and try setting Widescreen input to Yes. Otherwise,
set it to No.

If the projected colors seem slightly wrong:

❏ Press menu, go to Picture > Color settings, and adjust the color settings

as needed.

❏ Press menu, go to Picture > Color settings > Color space. Try the

different settings.

❏ Press menu, go to Help > Diagnostics, and run the color test.

If the projected colors seem completely wrong:

❏ Be sure the pins on the cable connectors are not bent or broken.
❏ Press menu, go to Picture > Color settings > Color space. Try the

different settings.

❏ Press menu, go to Help > Diagnostics, and run the color test.
❏ Press menu, go to Picture > Color settings > Reset color settings, and

press ok.

❏ Press menu, go to Setup > Reset all settings, and press ok.

If the picture is not clear (ghost images, smearing, poor quality):

❏ Be sure the video cable you are using is coaxial cable rated at 75 ohms.

Any other cable or impedance rating can reduce picture quality.

❏ The video cable connecting the video source to the projector probably

must be higher quality, especially if the cable is longer than about 3 m
(10 ft). Low-loss cable is recommended for longer distances to avoid
degrading or losing the picture

If a DVI source is not displayed when the DVI port is selected:

❏ Press menu, go to Setup > DVI compatibility, and select Standard

DVI.
