Belkin Secure DisplayPort KVM Switch, 4-Port, Dual-Head with CAC (F1DN104W-3) Review
The Belkin F1DN104W-3 is a secure DisplayPort-to-HDMI KVM switch with 4 computer ports and dual-head output, NIAP PP 3.0 certified.
It takes DisplayPort in from 4 computers and outputs to 2 HDMI monitors, with CAC support and NIAP PP 3.0 certification, but is capped at 4K30 rather than the newer 2nd Gen line's 4K60.
DisplayPort-In, HDMI-Out Design
The F1DN104W-3 takes DisplayPort 1.1/1.2 signals from 4 source computers and converts them to dual HDMI 1.4 outputs for the console monitors, maxing out at 3840x2160@30Hz UHD or 2560x1600@60Hz. It's certified to NIAP Protection Profile 3.0, an older standard than the PP 4.0 rating on Belkin's current modular line.
Audio and Power
Four 3.5mm audio inputs (one per computer) feed a single 3.5mm console output, and the unit runs off a 12VDC/3A external adapter that auto-ranges across 100-240V AC. At 12.5 x 6.4 x 2.5 inches and 4.9 lbs, it's a fairly substantial desktop enclosure.
