Problem

No video in either eye.

Comment

No video will be present without connection to a source.

Problem

Left Eye/Mono must have signal for Right Eye/Stereo to function properly.  Right eye is a

secondary channel for stereoscopic display.  Be sure all cables are securely attached to

the back of the V6 control box

Problem

Image in both eyes is not stable, or aspect ratio seems wrong.

Check

Incorrect video format.

Comment

Video format should be 640x480 60Hz.  Image may appear stable at different refresh

rates but should not be used.

Problem

Image in both eyes is unstable, rolling and flickering.

Check

Be sure SCSI connector was not removed from the control box while the power was  “on”.

Comment

It is possible that you removed the SCSI connector from the control box while the power

was “on”.  Contact Virtual Research for further assistance.

Problem

Image is too dark or too light.

Check

Adjust front panel brightness and contrast.  If unsuccessful check video termination.

Comment

Video should not be split to additional peripherals.  Use the provided monitor out

connection.
