Appendix A - Troubleshooting
There is no video Signal
•
Check that the power adapter is plugged in and the POWER LED is lit.
•
Check that the resolution of the input signal is 800x600.
•
Check that the video cable is plugged into the PC VGA output port.
•
Check that the screen refresh is set up correctly. The refresh rate should be
60Hz for 2D mode.
The picture is dark and fuzzy
•
Make sure that the external source is connected and is turned on.
•
Adjust
the
brightness of the display.
There is no sound
•
Check that the volume is not set to zero.
•
Check that the control is not muted.
The color appears incorrect
•
Check the color control settings.
•
Check that the VGA connector is properly inserted.
The image rolls, has static or is jumpy.
The 5DT HMD 800 is looking for a very precise 800 x 600 input signal at 60Hz. Some
computers may output a signal at a frequency other than 60Hz despite the fact that
your computer is set at 60Hz. Many computer monitors offer a “view meter” function
that will tell you the exact signal output. See your monitor manual for details. Try
raising or lowering your refresh rate slightly to see if this solves the problem.
The image flickers in 3D mode.
The 5DT HMD 800 operates at a refresh rate that is
double
the input refresh rate
up
to
60Hz. The headset will operate at the input refresh rate if the input rate is
above
60Hz. If you experience image flicker, make sure the input refresh rate is 60Hz or
less. Alternatively, reset the refresh rate on your computer to a minimum of 85Hz,
preferably 100Hz or higher. Generally, at a refresh rate above 85Hz, the human eye
should not be able to detect image flicker.
