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 Blustream Multicast system each source device only communicates with a single Blustream IP100UHD-TX
Transmitter meaning there is only a single EDID handshake. As each Blustream Multicast IP100UHD-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 IP100UHD-RX Receiver.
Configuration of Multicast EDID settings can be achieved in several ways:-
1) During the manual configuration of the IP100UHD-TX Transmitter
2) Using the Blustream Multicast PC configuration soware
3) Using the Multicast Web GUI interface
4) Using RS-232 commands via Blustream CM100
When configuring the EDID during manual setup or using RS-232 commands the following table indicates EDID values:

13 DVI 1920x1080@60Hz, Audio None
14 DVI 1920x1200@60Hz, Audio None
15 Default EDID (Pass-through)
16
4K2K 4:2:0 @ 60Hz, Audio 2CH PCM
17
4K2K 4:2:0 @ 60Hz, Audio 5.1CH PCM/DTS/DOLBY
18
4K2K 4:2:0 @ 60Hz, Audio 7.1CH PCM/DTS/DOLBY/HD
Note: The Blustream Multicast products do not down-mix Dolby Digital, DTS or 5.1ch audio signals. Should
your end-points (displays) only support 2CH PCM you must set the EDID value to match audio formats
supported throughout the system.
