About video output ports
Pearl Mini
An HDMI video output port is located on the rear panel of Pearl Mini. The output port is set to display
HDMI A input port by default, but you can change this using the Admin panel . The video output port is
configured to maintain aspect ratio, use the display's default resolution, and include audio at 100%
volume. However, the audio meter is not shown by default.
Using the video output port takes CPU cycles and adds to the overall load on your Pearl
device. For optimum performance, keep displays disconnected from the video output port if
you're not using them. Setups that already put a heavy load on the system's CPU may be
negatively impacted if the external video output port is used.
You can use the Admin panel to configure the video output port parameters. If you're simply selecting a
video source or channel and enabling/disabling audio for the output port, you can use your choice of
either the Admin panel, the Pearl device screen, or Epiphan Live (if you are using a Pearl Mini or Pearl-2).
For channels that have audio, the audio is enabled by default.
Important considerations
l
When changing encoding parameters for a channel that's displayed on the video output port, it
may revert to the display's default resolution if the output resolution is set to "Same as source". To
resolve this, change the video output to a different resolution then back to "Same as source".
l
When using the video output port for confidence monitoring, some delay can be expected. For a
1080p video source, the average delay on the video output port is approximately 100 ms. For a
1080p channel, the average delay on the video output port is approximately 300 ms. The actual
amount can vary, depending on the setup.
