be displayed correctly.
Troubleshooting
The image should appear properly on the screen(s).
If the image does not appear
1 . Ensure that all devices are plugged in.
2 . Make sure that each device is receiving power.
3 . Check the cabling, wiring and grounding, and make adjustments as
needed.
4 . Verify that the output configuration is correct for the display being used
(RGBHV, RGBs, RGsB, or component).
5 . Verify that the input type is correct (RGB or YUV).
6 . To test the system setup and output, substitute a video test generator for the
computer input.
7 . Confirm that the input is receiving a signal with a compatible scan rate
(horizontal frequency between 24 kHz and 70 kHz, and a vertical frequency
of 50 Hz to 120 Hz).
8 . Call Extron’s customer support hotline if needed. Be prepared to discuss
the steps you have taken and the equipment involved.
