EDID
EDID. What is it and what is it used for?
Under normal circumstances, a source device (digital and analog) will require information about a con-
nected device/display to assess what resolutions and features it can produce. Using this information
from the display, the source can then cater its output to send only resolutions and features that are com-
patible with the attached device/display. This information is called EDID (Extended Display Information
Data). A source device can only accept and read one EDID from a connected device/display. Likewise, the
source an only output one resolution for use by a connected device/display.
Why is EDID so important with the HDR 8x8 XT ?
The HDR 8x8-XT is a complex piece of technology that replicates and switches between multiple inputs
and outputs. Each connected source device will require one EDID to read. EDID management is carefully
handled by HDR 8x8 XT to provide a single EDID for each source to read.
What options do I have to manage the EDID in the HDR 8x8 XT ?
Each source device can only output one video/audio signal type (including resolutions and timings). When
multiple devices/displays are used, such as with the HDR 8x8 XT, using devices/displays that have com-
patible resolutions/features will reduce EDID errors. This will ensure that the single video/audio signal
produced by the source device is accepted by all of the connected output devices/displays. The user has
the option, through the EDID management window, to choose how the unit will manage the EDID from
multiple HDMI devices/displays. The HDR 8x8 XT has multiple EDID management modes that will control
how the EDID information from multiple devices/displays are combined, ignored, and routed.
