Enova DGX DVI Boards

Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers
Note:
If the signal is HDMI formatted, DGX DVI Boards can also work in conjunction with Audio Insert/Extract
Boards (page 119).
Important:
Signals through DVI Boards in the Enova DGX Switcher normally produce a quality image
because the connectors are pre-loaded with the most common EDID settings to ensure they will work with the
source devices. In addition to common EDIDs on the inputs, SmartScale on every output also greatly helps
ensure that all signals are satisfactory. Therefore, adjustments are not necessary unless the installation has
special scaling, EDID, or HDCP requirements. If re-programming of boards is necessary, DGX Configuration
Software (page 172) is available at www.amx.com.

If an HDCP protected signal is switched from a DVI Input Board to an output board which does not support
HDCP (e.g., the DGX SC Optical Output Board), the system will not allow the switch and will provide a
dark red image to that output to indicate the authentication process failed.
DVI Boards meet HDCP Standards and support InstaGate Pro Technology.
For complete information on HDCP functionality for DVI Boards, see “HDCP Support on Enova DGX
Switchers” on page 75.
DVI Input Boards provide EDID emulation support with plug-and-play information provided by the Enova
DGX Switcher.
DVI Output Boards feature SmartScale Technology which automatically responds to the display’s preferred
EDID information and scales the video to the best resolution and video parameters for that display without
manual setup.
DVI Boards are HDCP 1.4 compatible and feature InstaGate
Pro Technology* for low-latency switching of
HDCP protected content and support computer video up to 1920x1200 and HDTV up to 1080p. The EDID
of the input will need to be changed to allow for HDMI formatted signals, so that the source device can send
out that signal style. If the EDID on the input board has been properly modified and the downstream sink
has proper declarations in its EDID, the DVI connectors also support embedded audio, both linear PCM
(stereo audio) and non-linear PCM (Dolby Digital, DTS, Dolby TrueHD, etc.).
* InstaGate Pro Technology eliminates HDCP latency and interruptions on all displays in a system. (These conditions
are typically experienced when HDCP authenticates HDMI source and destination devices.) Key limitations on source
devices are also eliminated by allowing them to see only a single sink key from the DVI Input Board’s input connection.
With InstaGate Pro Technology, when a source requires HDCP encrypted content, the inputs and compliant downstream
devices are automatically authenticated – it just works.
Note:
Enova DGX Boards do not support CEC.
DVI Board Support for HDMI Signals - Changing the Default EDID Setting
The DVI Input Boards come pre-loaded with EDIDs typical for DVI output devices (computer monitors, etc.), which do
not support embedded audio signals. However, they will allow HDMI with embedded audio formats through if the
default EDID setting is changed via DGX Configuration Software using a file from the EDID Library (see page 182).
Note:
HDMI-to-DVI or DVI-to-HDMI conversion requires an applicable conversion cable.
Audio Support on DVI Boards
When DVI Boards are set up to support HDMI signals, the audio information in the HDMI Board chapter applies (see
page 78).
