8 602T, 602R - Using the Two-fiber Detachable Optical DVI System

4.3 Avoiding Pitfalls During Operation

If any of these problems occur, we recommend the following:

If the display device shows only a black screen:

• Check that all the AC and DC plugs and jacks used by the external power

supplies are firmly connected

• Check that the DVI ports are firmly plugged into the computer and the

display device, and be sure that the transmitter and receiver modules are

correctly plugged into the computer and display device, respectively

• Check if the computer and display are powered ON and properly booted

• Reset the system by unplugging and then replugging the transmitter DVI port

or receiver DVI port and then reboot the system

If the screen is distorted or displays noise:

• Check if the graphics resolution is properly set

• Go to the Display Properties of Windows and check the settings

• Be sure that the resolution is set for WUXGA (1920 x 1200) at 60Hz, or lower

• Reset the system

• Disconnect and reconnect the optical DVI cables

Be sure that at all times the cables are stored and used away from

liquid or dirt.
