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.
