EDID Control
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 device. From this information the source will discover
what the best audio and video resolutions need to be outputted.
In a normal Matrix based system issues do arise when multiple displays or video matrix switching is introduced because of the
increased number of variables.
In the ELAN Video Over IP system each source device only communicates with a single ELAN EL-4KPM-VIP-TX Transmitter, meaning
there is only a single EDID handshake. As each ELAN Video Over IP EL-4KPM-VIP-RX Receiver has its own in-built video scaler, it is
advised that the source EDID is set to output the best video signal possible as this can be down-scaled if required at each EL-4KPM-
VIP-RX Receiver.
Configuration of Video Over IP EDID settings can be achieved in several ways:-
1)
During the manual configuration of the EL-4KPM-VIP-TX Transmitter
2)
Using the ELAN Video Over IP PC configuration software
3)
Using the Video Over IP Web GUI interface
4)
Using RS-232 commands via ELAN EL-4KPM-VIP-CTRL
When configuring the EDID during manual setup or using RS-232 commands the following table indicates EDID values:

(displays) only support 2CH PCM you must set the EDID value to match audio formats supported throughout the system.
