NTI UNIMUX-HD4K18GB-32 (32-Port Rackmount 4K HDMI 18Gbps KVM Switch / $4230.77) Review
The NTI UNIMUX-HD4K18GB-32 is the top-of-line rackmount 32-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 $4230.77.
The 32-port model tops out the UNIMUX-HD4K18GB family and has the lowest cost-per-port of the whole line, making it the efficient choice once a deployment is genuinely operating at that scale — a single console workstation cycling through an entire row of 32 servers, all at full 4K@60Hz 4:4:4. Beyond 32 ports, buyers typically move to a proper KVM-over-IP matrix like the Raritan Dominion KX III rather than stacking multiple unit-switches. Versus the NTI UNIMUX-HD4K18GB-24 — 8 more ports for a proportionally smaller price jump, the more efficient buy at this scale. Versus the Raritan Dominion KX III (16/32/64 ports) already in this catalog — that adds full IP-based remote access and virtual media, worth it if remote administration matters more than a low per-port cost.

Expert Review
Reviewed by Burooj Alam. Rated by us, not by users.
Expert rating8.7 / 10
The best cost-per-port option in NTI's 4K HDMI rack switch family, ideal for a full row of local-access servers.
Best for
- Large server rooms needing local (non-IP) access to 32 machines
- Facilities standardizing on one console for a full server row
- Operations wanting the lowest cost per port in the UNIMUX-HD4K18GB line
Not for
- Deployments needing remote/IP-based access (see Raritan Dominion KX III)
- Smaller racks better served by the 8/16/24-port models
- Budgets that can't absorb the top-tier list price
