EDID Help:
EDID (Extended Display Identification Data) is a data structure that is used between a display and a source. This
data is used by the source to find out what audio and video resolutions are supported by the display then from this
information the source will discover what the best audio and video resolutions need to be output.
While the objective of EDID is to make connecting a digital display to a source a simple plug-and-play procedure,
issues can arise when multiple displays, or video matrix switching is introduced because of the increased number of
variables.
By pre-determining the video resolution and audio format of the source and display device you can reduce the time
need for EDID hand shaking thus making switching quicker and more reliable.
It is important, where possible, to set the source device to output a video resolution within the limit that the
Multicast IP Transmitter can accept. Where this is not possible, EDID management will request a suitable output
from the source device. Maximum input resolutions as follows: 3840x2160 @ 30Hz 4:4:4 8-bit, 4096x2160 @ 24Hz
4:4:4, 3840x2160 @ 60Hz 4:2:2, 3840x2160 @ 60Hz 4:2:0. Supports 4K with HDR at 30 / 25 / 24Hz.
Copy EDID:
The Copy EDID function allows the EDID of a display to be grabbed and stored within the ACM200. The EDID
configuraiton of the screen can be recalled within the EDID selection of the Transmitter. The displays EDID can then
be applied to any source device not displaying correctly on the screen in question.
It is recommended to ensure that the media from the Transmitter with the custom EDID displays correctly on
other displays within the system.
Please note: it is important that only one screen is viewing the Transmitter at the time the EDID Copy takes place.
