Set “3D Format” to “Side by Side”
Video images in the “Side by Side” format may not be recognized automatically in the case of 3D video images.

Is an intermediate device (AV amplifier, divider, etc.) in use?

Connect the source device to the projector directly, and check whether there is any improvement in the condition.
If the condition improves, it is likely that this is not caused by malfunction of the projector.

Is the cable in use an HDMI-certified cable?

Use an HDMI-certified high-speed cable.
Also, use as short a cable as possible.

Is the power of the 3D Glasses turned on?

If you are using the PK-AG2 or PK-AG3 3D Glasses, turn on the power manually.

Check the instruction manual of the 3D Glasses and 3D Synchro Emitter.

Are the 3D Glasses charged?

Check whether the PK-AG1 battery of the 3D Glasses has run out, and whether PK-AG2 and PK-AG3 are charged.

Are the 3D Glasses and 3D Synchro Emitter too far away from each other?

Position them at an appropriate distance.

Is the 3D Glasses and 3D Synchro Emitter combination correct?

Check the model name of 3D Glasses and 3D Synchro Emitter, and use the correct combination.

3D video image looks unnatural

Check

Action

Refer to

Are there overlapping video images?

If there are overlapping video images partially, this is due to the crosstalk phenomenon.
In this case, adjust “Crosstalk Cancel” accordingly.

If there are overlapping video images partially, this is due to the crosstalk phenomenon.
This phenomenon often occurs when there are drastic changes in the brightness.
In this case, set Lamp Power to “High”

Video image looks unnatural

Colors are unnatural

Check

Action

Refer to

Is the color space of the input signal correctly set?

The color may turn out unnatural when the input signal is different from that in the projector setting.
Set the “Color Space” for “Input Signal” correctly.

Is the image correctly adjusted?

Adjust “Color” and “Tint” accordingly.

Is the AV device or PC properly connected?

Connect the AV device or PC properly.

Video image flickers

Check

Action

Refer to

Do you see horizontally-extended, overlapping video images?

In this case, set “3D Format” to “Auto”

Are you viewing the video images under a fluorescent light?

This is caused by interference between the 3D glasses with the flickers of the fluorescent light.
View with the fluorescent light turned off.

ber

Is “Lens Aperture” set to “Auto 1” or “Auto 2”?

Set “Lens Aperture” to “Manual”

Flickers may sometimes occur upon starting up the projector unit, or immediately after the projector is changed from floor-standing to ceiling mounted. This is attributable to the lamp or drive mechanism, and is likely not caused by malfunction of the projector.

Projected image is dark

Check

Action

Refer to

Is the lamp near exhaustion?

Check the lamp time in the “Information” menu. Prepare a new lamp unit or replace as soon as possible when the lamp is near exhaustion.

Hold the remote control closer to the sensor during use.

Are the IR (infrared) 3D Glasses and 3D Synchro Emitter in use?

As there is a possibility of signal interference, when you are using the IR (infrared) 3D Glasses together with the 3D Synchro Emitter, try adjusting the orientation of the 3D Synchro Emitter.

The lens cover does not close RS640   RS540

Check

Action

Refer to

Is “Lens Cover” set to “Open”?

Set “Lens Cover” under “Lens Control” in the setting menu to “Auto”.

Noise is heard
