Extron electronics DA 2HD 4K PLUS, User Manual

Page: 23 / 42

Configuration
The DA HD 4K PLUS Series allows for adjustments to be made to ensure that the sink
devices are able to handle the source signal provided. Use
PCS software starting on
page 17 or SIS Commands starting on page 26 to make these adjustments.
This section provides information about:
•
EDID Minder
• HDCP
EDID Minder
EDID Minder ensures that a source device connected to the DA HD 4K PLUS input
continuously recognizes the EDID of a sink device, even if the sink is not physically
connected. By default, the EDID is set to 1080p @ 60 Hz with 2‑channel audio.
There are two, four, or six slots automatically populated by EDID from connected sink
devices.
NOTES:
• EDID can be managed in PCS (see EDID Minder on page 21).
• The unit supports EDID with resolutions up to 4K @ 60 Hz 4:4:4.
EDID Memory Retention
The assigned EDID is stored to an EEPROM, which is located at the HDMI input. The
stored EDID is retained until a reset is initiated.
Hot Plug Detect (HPD)
HPD remains high on the input while the unit is powered on. The HPD drops low only
while EDID is updated.
HDCP
Input
The HDMI input negotiates and authenticates HDCP with the source device if the source
requires HDCP encryption. The authentication process is repeated whenever the stored
EDID is changed or updated, which is indicated by pulling HPD low.
HDCP support can be disabled using the SIS command (see
HDCP Authorized Device
on page 30) or PCS (see HDCP Authorized on page 19).
Outputs
Each output is individually pre‑authenticated and encrypted, in accordance with the
configured HDCP output mode. If an output requires encryption but the connected sink
device cannot be authenticated, that output will display a green screen.
