SmartAVI SM-D2H-4Q-S (4-Port Quad-Monitor KVM Switch / $1012.21, was $1299.00) Review
The SmartAVI SM-D2H-4Q-S is a 4-computer, quad-monitor KVM switch bridging DisplayPort computer inputs to HDMI monitor outputs at 4K@60Hz, discounted to $1012.21 from $1299.00.
This fills the gap between SmartAVI's all-HDMI SM-UHN-4Q-S and all-DisplayPort SM-DPN-4Q-S in this catalog, taking DisplayPort from the computers but outputting HDMI to the monitor bank, useful when the workstation fleet and the monitor wall don't share the same native connector. It's priced between its two single-standard siblings, reflecting the added signal-bridging hardware inside.
Bridges DisplayPort Computers to HDMI Monitors
Rather than requiring the whole chain to match one video standard, the SM-D2H-4Q-S takes DisplayPort from up to four computers and converts it to HDMI for the monitor bank.
The Mixed-Signal Quad-Monitor Option
Fills a real gap for facilities whose workstations output DisplayPort but whose monitor wall is HDMI-native, avoiding a separate bank of adapters.
Comparison to Alternatives
Versus the SmartAVI SM-UHN-4Q-S — that requires all-HDMI end to end, worth it for a uniform HDMI fleet. Versus the SmartAVI SM-DPN-4Q-S — that requires all-DisplayPort end to end, worth it for a uniform DP fleet.

Expert rating8 / 10
The right pick when DisplayPort computers need to feed an HDMI-native quad-monitor wall without a pile of adapters.
Best for
- Four-computer setups with DisplayPort machines feeding an HDMI monitor bank
- Facilities avoiding a separate stack of DP-to-HDMI adapters
- Buyers needing quad-monitor 4K@60Hz across mixed video standards
Not for
- Uniform all-HDMI fleets (the SM-UHN-4Q-S is more direct)
- Uniform all-DisplayPort fleets (the SM-DPN-4Q-S is more direct)
- Two-computer setups (see the SM-DPN-2Q-S)
