StarTech CK4-PM202C Secure 2-Port Quad-Monitor KVM Switch with NIAP 4.0

Overview

The StarTech CK4-PM202C is a NIAP PP 4.0-certified secure KVM switch built for classified and sensitive compartmented information environments where signal isolation between hosts is non-negotiable. It connects two DisplayPort-equipped computers to a four-monitor HDMI console — giving operators full quad-display visibility while switching hosts — at up to 4K 30Hz. If you're deploying in a DoD, IC, or regulated government facility where peripheral sharing must meet Protection Profile 4.0 requirements, this is the switch to specify. Integrators sourcing for commercial high-security environments such as SOCs, trading floors, or defense contractor workstations will find the CK4-PM202C (often searched as CK4 PM202C) purpose-built for exactly this use case.

The switch ships in a solid metal chassis measuring 8.8 x 6.7 x 2.6 inches and weighing 3.9 lb — compact enough for a desk or shallow shelf, sturdy enough to stay put in a busy operator station. The all-black finish fits standard government and enterprise rack-adjacent deployments without drawing attention.

Key Features

• NIAP Common Criteria PP 4.0 Certification: This is the current highest-tier Protection Profile for peripheral sharing devices, required by many U.S. government procurement vehicles. Without it, a KVM cannot be approved for classified network segments — so if your deployment spec sheet calls for NIAP 4.0, this box checks that requirement directly.
• 2-Port Host / 4-Monitor Console: Two DisplayPort host connections feed a single four-HDMI-output console simultaneously. Operators keep all four screens populated regardless of which host is active, eliminating the disorientation of blanked monitors during switching. This matters on 24/7 analyst workstations where context-switching speed is operationally critical.
• 4K 30Hz Maximum Resolution: Each of the four HDMI console outputs supports up to 3840x2160 at 30Hz — sufficient for data-dense dashboards, map overlays, and multi-application analyst workflows. Note: 30Hz is appropriate for static or slow-moving content; if your operators run high-frame-rate video analysis, verify whether 60Hz is required and evaluate accordingly.
• DisplayPort Host Inputs (4x 20-pin DP Female): The four 20-pin DisplayPort female host connectors pair with current-generation workstation GPUs that output DP natively, avoiding the signal conversion chain that can introduce latency or certification complications in high-assurance environments. Two hosts use two DP inputs each to drive the full quad-display layout.
• USB 2.0 Console Peripherals (3x Type-A): Three USB 2.0 Type-A ports on the console side support keyboard, mouse, and a third peripheral — a CAC reader is the typical third device in government deployments — without requiring a separate hub. The USB path is hardware-isolated per NIAP 4.0 requirements, so keystrokes and mouse data cannot leak between hosts.
• Analog Audio I/O: A 3.5mm stereo female jack on the console side and two 3.5mm stereo female jacks on the host side provide audio switching alongside video and USB. Operators using headsets for classified voice communications can switch audio with the display and input, keeping the workstation ergonomically clean.
• Metal Chassis Construction: The all-metal enclosure provides RFI shielding consistent with secure facility requirements, and it won't flex or crack under the repeated cable stress that plastic KVM housings develop over time in operator environments. At 3.9 lb it has enough mass to stay stable without being bolted down.
• Operational Temperature Range 0°C to 40°C: Rated for standard conditioned office and control room environments. It is not rated for extreme temperature ranges — if your deployment includes unconditioned equipment rooms or outdoor enclosures, confirm your HVAC envelope before specifying.
• 3-Year Manufacturer Warranty: StarTech backs the CK4-PM202C with a 3-year manufacturer warranty, which aligns with typical government and enterprise refresh cycles and reduces procurement risk on a switch that may sit in a classified facility for years before replacement.

Integration and Compatibility

The CK4-PM202C is designed for workstations with discrete DisplayPort outputs — verify that both source computers provide at least two DP outputs each to populate all four console monitors. The four HDMI console outputs connect to any HDMI-capable display, including the large-format 4K monitors common in government and SOC deployments. USB 2.0 is the console peripheral interface; USB 3.x devices will operate at 2.0 speeds through the switch, which is standard for keyboards, mice, and smart card readers. Audio connectivity uses standard 3.5mm analog — compatible with most operator headsets and desktop speakers. For broader context on KVM switches and how secure models compare to standard desktop KVMs, review the available selection by category. StarTech's full product line includes cabling and accessories that complement this switch in secure workstation builds. Buyers procuring for multi-operator environments should also review KVM accessories including compatible cable sets. For environments combining video surveillance with analyst workstations, pairing this switch with a well-planned NVR infrastructure ensures operator displays receive the full resolution feeds the switch can handle.

Frequently Asked Questions

Q: What NIAP certification level does the CK4-PM202C carry?

A: The CK4-PM202C is certified to NIAP Common Criteria Protection Profile for Peripheral Sharing Devices version 4.0, the current highest-tier PP for KVM switches used in classified and sensitive government environments.

Q: How many monitors and computers does the CK4-PM202C support?

A: It supports 2 host computers (each connected via DisplayPort) and drives 4 HDMI monitors simultaneously on the console side, maintaining all four displays regardless of which host is active.

Q: What is the maximum resolution the CK4-PM202C supports?

A: The CK4-PM202C supports up to 4K (3840x2160) at 30Hz across all four HDMI console outputs. If your application requires 4K at 60Hz, confirm this switch meets your frame rate requirement before specifying.

Q: What USB peripherals can I connect to the console side?

A: The console side provides 3x USB 2.0 Type-A ports — sufficient for keyboard, mouse, and a third device such as a CAC/smart card reader. USB 3.x devices will function at USB 2.0 speeds.

Q: What is the warranty on the CK4-PM202C?

A: StarTech provides a 3-year manufacturer warranty on the CK4-PM202C.

Q: Does the CK4-PM202C support audio switching?

A: Yes. The switch includes one 3.5mm stereo female jack on the console side and two 3.5mm stereo female jacks on the host side, enabling analog audio to switch with the active host selection.

The spec that defines whether the CK4-PM202C belongs in your deployment is the NIAP PP 4.0 certification — not the quad-display layout, not the 4K resolution. PP 4.0 is the benchmark that procurement officers look for when a KVM is destined for a classified or SCI-adjacent workstation. If your facility security officer's approved products list requires PP 4.0, this switch qualifies. If your deployment is commercial with no classified network requirement, you're paying a certification premium you don't need, and a standard secure KVM would be a better fit on cost.

Technical Highlights:

• NIAP PP 4.0: The current highest Protection Profile tier for peripheral sharing devices — hardware-enforced isolation between the two host USB and video paths, not software-based switching, which is what the certification actually validates.
• 4x HDMI Console at 4K 30Hz: All four outputs run simultaneously at up to 3840x2160, so analyst workstations retain full quad-display context when switching between the two hosts — no re-arrangement, no blank screens.
• Metal Chassis, 3.9 lb: The enclosure weight and construction are consistent with RFI-hardened secure facility requirements; at 8.8 x 6.7 x 2.6 inches it sits on a desk or mounts behind a monitor arm without a dedicated rack space.

Deployment Considerations:

• Each host computer must provide two DisplayPort outputs to fully populate the four console monitors — confirm your workstation GPU spec before ordering; single-DP workstations will not drive all four displays.
• The 30Hz ceiling on 4K output is a real constraint for video-intensive workflows. Analysts reviewing high-frame-rate surveillance feeds may find 30Hz visually limiting at 4K; dropping to 1080p on those specific monitors would recover frame rate headroom through the HDMI path.

The CK4-PM202C is the right call for a two-workstation classified analyst station in an IC or DoD environment where NIAP PP 4.0 is a hard procurement requirement and the operator needs uninterrupted quad-display visibility across both hosts — a common layout in 24/7 watch floor configurations.
