Appendix. Troubleshooting
A.1 Symptoms, Possible Causes, and Solutions
Symptom: Video does not display on some ports.
Possible Cause: DVI specification of the source devices doesn’t match the DVI
specification of DVI cable and/or the DVI display device.
Solution #1: There are three DVI standards: DVI-I, DVI-D, and DVI-A. Make sure
that DVI specifications of the source devices, cables, and monitors all match.
NOTE: Some monitors can support multiple DVI signals.
Solution #2: Make sure the splitter was connected to the source computer before
powering on the computer.
Symptom: Erratic behavior
Possible Cause: The splitter might not receive enough power.
Possible Solution: Make sure the power adapter attached to the splitter matches
the system specifications, and that it is functioning properly.
Symptom: Not receiving picture or sound.
Possible Cause #1: Wrong installation process.
Solution #1: The video splitter requires at least one monitor connection before
powering on the source device.
Possible Cause #2: The signal source may require a display device that is HDCP
compliant.
Solution #2: Check if the display monitor is HDCP compliant. HDCP prevents the
transfer of digital content to unauthorized HDMI devices.
Possible Cause #3: The display monitor is added to the unit by hot-plug, but the
video source may not support hot-plug.
Solution #3: Check if the video source supports hot-plug. If it doesn’t, shut down
the source device and reboot it again.
