SmartAVI SDHN-2D-P 2-Port Dual-Head Secure KVM (DP to HDMI) Review

SmartAVI SDHN-2D-P 2 port dual head DisplayPort to HDMI secure KVM CAC classified conversion

The SDHN-2D-P solves a specific, common problem: source computers with DisplayPort outputs feeding a facility's existing HDMI monitor fleet, with the same secure dual-head switching and CAC support the rest of the SmartAVI N-series delivers.

DP-to-HDMI Conversion Built In

Rather than requiring separate DisplayPort-to-HDMI adapters in the signal path — which would sit outside the KVM's security boundary — the SDHN-2D-P performs the conversion inside its own certified, isolated hardware, keeping the video path within the evaluated security boundary end to end.

CAC Included Standard

Unlike the SDVN and SDPN 2-port lines, which offer separate non-Pro and Pro variants, the SDHN-2D-P ships with the switched CAC/PIV port as standard, reflecting its positioning as a fuller-featured conversion switch.

Comparison to Alternatives

Against the SDPN-2D-P, which requires DisplayPort monitors, the SDHN-2D-P is the pick when computers output DisplayPort but the facility's existing displays are HDMI-only. For 4-system coverage, see the SDHN-4D-P.

Expert rating7.7 / 10

The right choice when DisplayPort source computers need to feed an existing HDMI dual-monitor fleet without breaking the secure isolation boundary.

Best for

Facilities with HDMI monitor fleets fed by DisplayPort-output computers
2-system dual-monitor desks needing built-in DP-to-HDMI conversion
Sites requiring CAC switching without a separate reader

Not for

Native DisplayPort monitor environments (see SDPN-2D-P)
Native HDMI source computers (a direct HDMI switch is simpler)
4-system desks better served by the SDHN-4D-P
