Fiber Optic Troubleshooting
No video and/or digital link present
• Check all the C/Port and fiber optic cables and their associated jacks for signs of
damage or wear. Replace any suspicious cables with new, commercially
manufactured cables and test the remaining cables with a quality tester.
• Non-commercial cables are frequently the culprits when equipment fails to work
properly. For this reason, ClearCube strongly discourages the use of
Non-commercial cables.
• Check that the power supply brick is the proper one for the Fiber C/port. It should
have a rated output of +5 VDC, 7 A; –5 VDC, 1 A. The power supply for the
standard C/Port and the MVX does not work with the Fiber C/Port.
The monitor’s Auto-Adjust does not give a clear, sharp
image
• Monitor auto-adjust routines do not always optimally adjust the image. Using the
auto-adjust routine a second or even third time may provide a better result.
Because all monitor manufactures have unique adjustment settings and
auto-adjust algorithms, customers should contact the monitor manufacturer
directly for assistance in achieving the optimal image quality.
• Use the monitor’s manual functions to adjust picture size, position, brightness,
and contrast.
