EDID management:
The EDID configuration is used to control the EDID data communication from the display device to the
signal source. You can specify EDID values to force the video sources to output these pre-set signal
timings. This affects both, audio and video in HDMI and display port signals.
The QuickSelect 3.0+ has three available EDID tables per HDMI input:
1. Auto EDID, 2. Predefined (factory-set) EDID, 3 user-specific EDID.
The respective table is selected via the active mode in the GUI.
Info: What is EDID
EDID information (Extended Display Identification Data) is made up of a 128 Byte (VGA) or 256 Byte data
structure (HDMI) that is saved in a video display/projector or another output device. It contains the resolutions
that can be displayed for the output device, incl. refresh rate, audio formats etc.
The source device asks the output device for this table before establishing the picture and selects the best
resolution for the picture output from it.
Note:
By using the external contact switches for source-switching only the signal on the HDBT-Out can be
selected. Local HDMI-Out and Audio-Out will follow those commands only if „Link In/Link Out“ is selected.
The default setting is“Link In/Link out”. In this case any signal coming via Link In from the proceeding unit
as well as signals infed locally will be available on both outputs, HDMI and Link Out, at the same time.
The QuickSelect 3.0+ system does not automatically forward the EDID table of the end device to the
picture source. Under certain circumstances, this would also not be desired, singe, e.g., DVI end devices
do not contain any sound information – thus the laptop would also not output any sound via HDMI.
Therefore, EDID management is provided in the GUI of the QuickSelect 3.0+.
1. The simplest setting ‚Auto EDID‘ is part of the basic configuration
under ‚Auto Set‘. In expert mode, you can read the EDID information
from the last connected output device with the button ‚Auto EDID‘
and thus automatically file it in the Auto EDID memory of the Quick-
Select 3.0+. This is displayed in the output field in the middle in HEX.
To activate this table, the EDID mode of the respective QuickSelect
3.0+ must be set to auto. In the pulldown menu, you can choose
whether the Auto EDID memory is activated for the input HDMI1,
HDMI2 or both. On the left, for all devices that were found under
‚Auto search‘; on the right only for the selected device (framed red).
The captured EDID data can be saved locally for later purposes with
the ‚Save‘ button (if the output device is e.g. no longer available).
2. In ‚Predefined‘ mode, a factory-set EDID is used. Again, you can
choose in the pulldown menu whether the pre-set EDID data record
for the input HDMI1, HDMI2 or for both is activated. On the left, for all
devices that were found under ‚Auto Detect‘; on the right only for the
selected device (framed red).
