4K60 Signal Routing
DGX 4K60 HDMI Input Boards route video from a source device through the Enova DGX to an output board (or via a
DXLink Output Board to a DXLink Receiver). However, 4K60, 4K30, and 2K signals require substantially different hardware
support.
For this reason a system Pre-Qualification feature has been added to the Enova DGX to allow signal routing to any output
that is capable of Supporting the current video signal. Video signal path capabilities are based on the lowest common
denominator of the signal path's components: In order to receive video at the destination device, the entire signal path
(source device, input board, output board, receiver module, and destination device) must support the current video
formats.
If 4K60 signals are passed to output boards or Receiver Modules that are not 4K60 capable, no signals will be shown on
the destination device. To resolve compatibility issues, change the format from the source device or route the 4K60
formatted signal to a 4K60 capable output board. Refer to the
Video Signal Support Tiers
section below for a complete
description.
NOTE:
PreQual is a signal Pre-Qualification feature that enforces signal path limitations and provides system-level
indications via ICSP and the System Configuration Interface when a signal is blocked to an output port due to an
incompatible source format."
NOTE:
4K60 HDMI Boards requires at minimum a High Speed Category 2 cable, but we recommend "Certified Premium
High Speed" HDMI cable for any 4K50/4K60 content.
Video Signal Tiers Support
DGX 4K60 HDMI Boards handle the following three tiers of video signal components:
1.
2k
– video formats up to HDMI 1.3a
2.
4k30 – 4k video formats that can be passed with HDMI 1.4 (up to HDCP 1.4 and HDCP 2.2 non-Premium)
3.
4k60 – 4k video formats that require HDMI 2.0 (up to HDCP 1.4 and HDCP 2.2 Premium or non-Premium)
NOTE:
For ease of initial installation the default EDID on the input cards is set to 4k30. This EDID will support 4K60 4:2:0
formats. If all of the 4K hardware in all of the desired paths support 4k60 4:4:4 or 4k60 4:2:2 formats, then you may want to
change the EDID on the appropriate input channel(s) to a 4K60 EDID. See the System Configuration Interface
for more information.
3rd Party Equipment Requirements for DGX 4K60 HDMI Boards
In contrast to other Enova DGX output points, DGX 4K60 HDMI Output Boards DO NOT utilize SmartScale
technology. Therefore, the use of DGX 4K60 HDMI Output Boards requires the use of 3rd party equipment with
matching video capabilities. Additionally, the installer must configure DGX 4K60 HDMI Boards to use the
appropriate EDID and/or timing for target devices via the
VIDIN_PREF_EDID
(see page 216).
DGX 4K60 HDMI Boards do not provide free-run video. Therefore, when a signal path is disconnected, DGX 4K60
HDMI Boards will lose the signal at the output point. In some cases (as with some projectors), this could cause some
sinks to shutdown (which can take a long time for a projector).
