Use a specific EDID for the video input port
Extended display identification data (EDID) is data provided by a video display device, like a monitor. The
EDID describes the display's capabilities to a video source, such as the graphics card in a PC or other video
output device.
In Pearl Nano, the video source uses the EDID information to determine what resolutions, color depth,
and other settings the monitor supports.
EDID is crucial for DVI sources.
The video input ports on Pearl Nano have a factory set EDID. When you connect a video source such as a
laptop or camera to Pearl Nano, the video source sees Pearl Nano as if it were a monitor. The EDID that's
assigned to the input port is read by the video source to determine what video signal it needs to send to
Pearl Nano.
Usually, the video input ports on Pearl Nano correctly emulate a monitor for the connected video source.
However, there are times when you may need to upload a custom EDID, like when your source uses a
custom set of display properties.
When you upload a custom EDID to an input port on Pearl Nano, you can force the port to supply a
specific resolution, color depth, etc to the connected video source.
Upload a new EDID
In most cases, the factory installed default EDID works fine for sources connected to the HDMI ports on
Pearl Nano. However, there may be times when a connected video source uses resolutions that you do
not want to use. In that case, you can manually upload an EDID and force Pearl Nano to use a specific set
of attributes for a specific HDMI input port. All video sources you connect to that HDMI input port will use
the EDID you've manually assigned to the port.
EDID changes remain in effect for the HDMI input port until you replace the EDID with another one or
specifically choose to restore the factory EDID for that specific HDMI input port. A system-level factory
reset does not remove a manually assigned EDID from the HDMI port.
