EDID Management
EDID (Extended Display Identication Data) is a data structure that is used between a display and a source. This data
is used by the source to nd out what audio and video resolutions are supported by the display. By pre-determining
the video resolution and audio format of the source and display device you can reduce the time needed for EDID hand
shaking thus making switching quicker and more reliable.
Conguration of the EDID settings for each input can be achieved using the following RS-232 commands to specify the
required EDID:
EDIDxxDFzz
Where xx = Input: 00 refers to ALL inputs; 01-08 = specic input
zz = EDID as shown below
zz = 00 : HDMI 1080p@60Hz, Audio 2ch PCM (default)
01 : HDMI 1080p@60Hz, Audio 5.1ch DTS/DOLBY
02 : HDMI 1080p@60Hz, Audio 7.1ch DTS/DOLBY/HD
03 : HDMI 1080i@60Hz, Audio 2ch PCM
04 : HDMI 1080i@60Hz, Audio 5.1ch DTS/DOLBY
05 : HDMI 1080i@60Hz, Audio 7.1ch DTS/DOLBY/HD
06 : HDMI 1080p@60Hz/3D, Audio 2ch PCM
07 : HDMI 1080p@60Hz/3D, Audio 5.1ch DTS/DOLBY
08 : HDMI 1080p@60Hz/3D, Audio 7.1ch DTS/DOLBY/HD
09 : HDMI 4K@60Hz 4:2:0, Audio 2ch PCM
10 : HDMI 4K@60Hz 4:2:0, Audio 5.1ch DTS/DOLBY

Automatic Smart Scaling Functionality in CSC
RTI HDBaseT™ CSC (Color Space Conversion) outputs have an in-built automatic smart scaling feature allowing for a 4K
video signal to be independently downscaled per individual HDBaseT™ output connection. The Matrix will read the EDID
of the display attached to the VRX70-18G HDBaseT™ receiver output, downscaling the video resolution automatically
where the display cannot accept the native resolution being sent from the source device. CSC will auto-downscale
either video resolution, chroma sampling, or color bit depth, it is not able to amend frame rate, or HDR elements within a
signal.
The simultaneous HDMI output (output 1) will continue to pass the native signal.
Native Source Signal Smart Scaled Output Capability
4K xHz 4:4:4 4K xHz 4:2:0 (or) 1080p xHz 4:4:4
4K xHz 4:2:2 4K xHz 4:2:0 (or) 1080p xHz 4:4:4
4K xHz 4:2:0 1080p xHz 4:4:4
x = frame rate, will be equal from native to converted/scaled
Please Note: smart scaling is automatic based on the EDID of the display and cannot be controlled or adjusted by the
user / integrator. To obtain resolutions lower than 1080p, a separate scaler device must be specied.
To obtain CSC pass-through the RTI VX88-18G Matrix must be used with RTI VRX70-18G HDBaseT™ Receivers. Using
an alternative RTI HDBaseT™ receiver will result in the CSC functionality not being available so the maximum output
resolution will be 4K 60Hz 4:2:0 (10.2Gbps).
