4) Internal Test Pattern
This advanced matrix system comes with an internal test pattern
generation feature which can be used to test connected sink
device functionality or be used as a self-test. This is a useful tool for
installation engineers to troubleshoot potential issues between the
matrix and connected devices.
This can also be used as a video source for any connected "audio only"
sources in cases where only a TV is available for audio reproduction
and it requires an active video source in order for the audio to be
heard.
Note: The test pattern is only active when the "Pattern" input is routed to
the specified output.
■ Timing: Test patterns can be generated on either the HDMI or
HDBaseT outputs at the following standard resolutions with a
variety of refresh rates: 480i/p, 576i/p, 720p, 1080p, 4K. Test pattern
output does not enable HDCP.
