EDID MANAGEMENT FEATURE
EDID. What is it and what is it used for?
Under normal circumstances, an source device (digital and analog) will require
information about a connected device/display to assess what resolutions
and features are available. The source can then cater its output to send
only resolutions and features that are compatible with the attached device/
display. This information is called EDID (Extended Display Information Data)
and 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 1:8 Distribution Amplifi er for HDMI?
The 1:8 Distribution Amplifi er for HDMI is complex piece of technology that
replicates a single source to multiple outputs. The single source device will
require one EDID to read. EDID management is carefully handled by 1:8
Distribution Amplifi er for HDMI to provide a single EDID for the source to read.
What options do I have to manage the EDID in the 1:8 Distribution Amplifi er
for HDMI?
First, it is important to note that each source device can only output one video/
audio signal type. This includes resolutions and timings. When multiple devices/
displays are used, such as with the 1:8 Distribution Amplifi er for HDMI, it is
important to use devices/displays that have similar or compatible resolutions/
features. 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 a combination of DIP switch settings within the
1:8 Distribution Amplifi er for HDMI, to choose how the unit will manage the EDID
from multiple HDMI devices/displays. Therefore the user has some control over
the resolutions/features that the source device will output. The 1:8 Distribution
Amplifi er for HDMI has a multiple EDID management modes that will control how
the EDID information from multiple devices/displays are combined, ignored, and
routed.
How do I change EDID modes in the 1:8 Distribution Amplifi er for HDMI?
There is an bank of 8 DIP switches located on the main-board inside of the 1:8
Distribution Amplifi er for HDMI. DIP switches 1, 2, 5, and 7 are used in different
combinations to manage the EDID modes.
To access these DIP switches it will be required to open the unit. To do this,
remove all screws on the underside and side of the unit. Remove all HEX screws
on the rear panel. This includes the screws above each HDMI port. Carefully
slide the unit apart and locate the DIP switch bank on the main-board.
