Proprietary
Creating a DVI-I configuration using the DAC signals (RED, GREEN, BLUE, DACHSYNC, etc.) plus the TMDS output
multiplexed on the PCI-E graphics links is supposed to work as well, but the configuration is not recommended since it
cannot be validated using any of AMD's current internal reference boards.

HDMI
The RS690E has an integrated controller that allows support for a single-link HDMI (video and audio) transmission on
the LVTM interface. For details on HDMI audio support, please refer to
section 1.5.11, “DVI/HDMI (Not applicable to
. Also, like the RS690T, the RS690E’s TMDS interface that is multiplexed on its PCI-E
graphics lanes can also enable HDMI (single-link only).
Note:
The TMDS interface multiplexed on the PCI-E graphics lanes cannot enable HDMI when the LVTM interface is
supporting HDMI, and vice versa.
B.5
HDCP
The RS690E supports HDCP on data streams for single-link transmission, with on-chip key storage. It is available either
on the DVI/HDMI data stream driven by the LVTM interface or on the data stream driven by the TMDS interface
multiplexed on the PCI-E graphics lanes, but both digital outputs cannot be HDCP protected simultaneously.
Note:
HDCP content protection is only available to licensed buyers of the technology and can only be enabled when
connected to an HDCP-capable receiver.
