StarTech CK4-P204C 4-Port Dual-Monitor KVM Switch

Overview

The StarTech CK4-P204C is a secure 4-port dual-monitor KVM switch built for operators who need to control multiple air-gapped or sensitive PCs from a single console without introducing a data-leakage path between them. It switches two DisplayPort video streams plus USB peripherals across four host PCs, and it carries NIAP 4.0 certification — the kind of validation security-conscious government and enterprise buyers specifically ask for when a KVM sits between classified, regulated, or otherwise segmented systems. If you're running a security operations center, a network operations desk, or any multi-system control room where operators pivot between machines all day, CK4-P204C is built to answer the question of whether a shared KVM can be trusted on a segmented network.

Key Features

• 4K 60Hz dual-monitor support: both displays run at full 4K 60Hz simultaneously, so operators get smooth, high-resolution video for CAD, video wall monitoring, or dense multi-window dashboards instead of choppy 30Hz fallback.
• 4 KVM ports via DisplayPort host connectors: eight 20-pin female DisplayPort host connectors (two per PC across four PCs) let you consolidate four workstations onto one keyboard, mouse, and monitor pair — fewer peripherals cluttering the desk and fewer places for data to cross between systems.
• NIAP 4.0 certification: validated against NIAP's Protection Profile for peripheral sharing switches, which matters directly if you're procuring for a government, defense, or regulated environment where uncertified KVMs are a compliance blocker.
• 3 USB 2.0 Type-A console ports: enough headroom for keyboard, mouse, and a third peripheral (token reader, headset) at the operator console without needing a separate hub.
• All-metal enclosure: a metal chassis holds up to continuous desk use and repeated switching in a 24/7 control room setting far better than a plastic housing that flexes and cracks over time.
• Wide operating range, 0C to 40C: covers standard office and control-room environments without special HVAC accommodation.
• Humidity tolerance to 80% RH: keeps the switch reliable in less climate-controlled equipment rooms, not just pristine data centers.
• Storage range -20C to 60C: gives integrators margin for shipping and warehousing before install without worrying about internal component stress.
• Compact footprint at 12.6 x 6.7 x 2.7 inches: fits on a console desk or in a rack shelf without eating the space a full server-room switch would need.
• 3-year warranty: longer coverage window than typical consumer KVMs, reflecting a build intended for continuous professional use rather than occasional home switching.

Integration & Compatibility

CK4-P204C connects over native DisplayPort end to end — PC interface and host connectors are both DisplayPort — so it pairs cleanly with workstations already outputting DisplayPort video without adapters or signal converters in the chain. Because the video path stays digital DisplayPort throughout, you avoid the resolution drops or EDID handshake issues that show up when mixing HDMI-to-DisplayPort adapters into a KVM chain. For control rooms already standardized on KVM switches for multi-system management, the CK4-P204C (often searched as CK4 P204C) slots in as the secure-tier option where NIAP validation is a procurement requirement rather than a nice-to-have. Pair it with a dual-monitor mount to keep both 4K displays positioned correctly at the operator desk, and review a KVM switch buying guide if you're still confirming port count and resolution needs across your fleet before ordering. It sits within the broader StarTech catalog of connectivity and KVM hardware built for IT and security integrators managing multi-PC environments.

Frequently Asked Questions

A: It supports 2 monitors and switches between 4 host PCs, with 8 DisplayPort host connectors total (2 per PC).

Q: What resolution does the CK4-P204C support?

A: Both monitor outputs support up to 4K at 60Hz.

Q: What's the warranty on the CK4-P204C?

A: It carries a 3-year warranty.

Q: Where is the CK4-P204C manufactured?

A: Country of origin is listed as USA.

Q: What ports are on the console side of the CK4-P204C?

A: Three USB 2.0 Type-A ports for keyboard, mouse, and other peripherals.

What stands out on the CK4-P204C is the NIAP 4.0 certification paired with genuine 4K 60Hz dual-monitor output — most secure KVMs force a tradeoff between certification and video performance, and this one doesn't.

Technical Highlights:

• 4K 60Hz on both heads: full-rate 4K across 2 monitors simultaneously means no resolution or refresh compromise when switching between 4 PCs.
• 8 DisplayPort host connectors: 2 per PC across 4 hosts keeps the video path native DisplayPort end-to-end, avoiding adapter-induced handshake issues.
• NIAP 4.0 certification: meets the Protection Profile bar that government and regulated buyers require before a shared peripheral switch can touch segmented systems.

Deployment Considerations:

• All-metal construction and a 0C to 40C operating range make this a fit for control-room desks running continuous shifts, not just occasional switching.
• Console side is USB 2.0, not 3.x — fine for keyboard, mouse, and low-bandwidth peripherals, but don't plan on high-throughput USB storage through the console ports.

This is the model to spec for a SOC or NOC desk where operators need to pivot across 4 segmented PCs on dual 4K displays and procurement requires NIAP validation on the switch itself — the CK4-P204C is built for exactly that brief.
