EDID
(Extended Display Identification Data)
Edid is the standard compatibility signal passed between most sources and video displays. It
allows the devices to make sure they support the same resolutions and timing.
Output 2
The AT-HD-V1616M has two EDID settings: default and learning. Default saves the settings
of 1080p resolution and 2 channel audio to all outputs. The learning setting will allow for the
copying of an output’s EDID to specific inputs.
Default
Default is used for when all displays support 1080p and 2 channel audio. If a display does
not support this resolution then it will show only a black screen. (i.e. Output5 having the native
resolution of 720p would cause it to show only a black screen in default)
1080p-Dolby TrueHD (3D)
Input 4
1080p
Input 2
720p
Input 8
720p
Output 5
Output 11
1080p-2ch
1080p-Dolby TrueHD (3D)
Learning
Learning EDID allows for the resolution and audio formats of a display to be saved to an input
source. Once this setting is saved it will only output that resolution and audio, which will cause a
black screen to display on any output that does not support the same settings.
I.E. If you save the settings of output11 to input4, input4 will only display 1080p and Dolby
TrueHD audio, which means output5 would receive no audio or video and output2 would receive
no audio.
If the settings of output11 to input4 are saved with 3D only 3D capable devices will be able to
get picture with input4. Input4 will be saved to 3D and a separate Blu-ray or DVD player will be
needed to be used with outputs incapable of 3D. Input4 will no longer be able to show anything
but 3D and will not play in any other resolutions.
In the above diagram, output5 can be saved to all 3 inputs allowing all three outputs to use the
devices at 720p (most displays have multiple resolution capabilities. Outputs 2 & 11 however
can only be saved to inputs 2 & 4 as their native resolutions are 1080p and input 8 is incapable
of producing that resolution without a scaler.
