EDID (Extended Display Identifi cation Data) contains information on the
resolution and general capabilities of a display device. This information is used
by the source device to output a compatible signal that the display can accept.
This information can even be used by some source devices to limit the output
of resolutions and features that the display is not capable of accepting. In single
source and single device setup, EDID can effectively ensure compatibility with
display and source. The 1:5 Splitter For HDMI Over CAT-5 replicates a single
HDMI input from a source to up to 5 HDMI capable devices. However, since the
source device can only output one type of audio and video signal (resolution,
features, number of audio channels, audio format, etc.) based on the EDID
it receives, all connected HDMI devices must have common audio and video
capabilities for successful replication to occur.
The source of the EDID can be selected using the EDID mode feature. There are
two sources from which the EDID can be polled and then transferred back to the
source device. The External mode uses the EDID from the display connected to
the fi rst HDMI output port. The Internal mode will use and built-in EDID that is
stored in the unit. The Internal EDID mode supports resolutions of up to 1080p
and includes common audio features.
How to Change EDID Modes
Locate the EDID Mode Switch on the rear panel of the 1:5 Splitter For HDMI 1.
Over CAT-5 sender unit.
Note the switch’s current position and change the EDID mode to either INT 2.
(Internal) or EXT (External) by toggling the switch.
Press the reset button on the front panel to reset the connection to the 3.
source device so that it can re-detect the new EDID change.
