NTI UNIMUX-HD4K18GB-16 (16-Port Rackmount 4K HDMI 18Gbps KVM Switch / $2405.13) Review
The NTI UNIMUX-HD4K18GB-16 is a 1U rackmount 16-port KVM switch supporting full-bandwidth 18Gbps HDMI 2.0 at 4K@60Hz 4:4:4, with 2 transparent USB 2.0 ports, HDMI audio switching, and RS-232 control, priced at $2405.13.
At 16 ports the UNIMUX-HD4K18GB line moves from a single small cluster into genuine data-center territory, still packed into one 1U enclosure and still switching every port at full 4K@60Hz 4:4:4 rather than dropping bandwidth as port count climbs, which is where some competing rack switches start to cut corners. RS-232 control makes it scriptable for larger operations that automate server access. Versus the NTI UNIMUX-HD4K18GB-8 — half the ports for meaningfully less money, right-sized for smaller racks. Versus the NTI PRIMUX-UZR already in this catalog — that's a larger matrix switch supporting up to 64 servers, worth it for even bigger deployments needing many-to-many routing rather than a single console.
16 Ports at Full Bandwidth
At 16 ports the UNIMUX-HD4K18GB line moves from a single small cluster into genuine data-center territory, still packed into one 1U enclosure and still switching every port at full 4K@60Hz 4:4:4 rather than dropping bandwidth as port count climbs.
Built for Automated, Scripted Access
RS-232 control makes it scriptable for larger operations that automate server access rather than relying purely on front-panel buttons.

Expert rating8.5 / 10
A data-center-ready 16-port 4K HDMI switch that holds full bandwidth across every port.
Best for
- Data center racks needing 16 full-bandwidth 4K@60Hz sources
- Operations wanting RS-232/network scripted control
- Teams standardizing on the UNIMUX-HD4K18GB platform across sizes
Not for
- Small deployments of 4-8 machines (see smaller models in the line)
- Budgets that don't need full 60Hz across every port
- Many-to-many routing needs better served by a true matrix switch
