StarTech CK4-PM102C 2-Port Dual-Monitor Secure KVM Switch

Overview

The StarTech CK4-PM102C is a NIAP Protection Profile for Peripheral Sharing Devices 4.0 (PSD 4.0) certified, two-port dual-monitor KVM switch built for high-security computing environments where keyboard, video, and mouse isolation between hosts is a compliance requirement — not just a convenience. It supports two computers simultaneously, each driving up to two DisplayPort monitors at 4K 60Hz, using a hardened metal enclosure manufactured in the USA. If your deployment involves classified networks, government workstations, or air-gapped systems that must meet formal NIAP certification requirements, the CK4-PM102C was designed precisely for that use case.

Key Features

• NIAP PSD 4.0 Certification: This is the current highest-level NIAP standard for peripheral sharing devices. Deployments on classified or sensitive compartmented information (SCI) networks often require NIAP PSD 4.0 — a listing that disqualifies most commercial KVM switches outright. This certification means the device has been independently validated to prevent data leakage between connected hosts.
• Dual-Monitor DisplayPort at 4K 60Hz: Each of the two ports drives a pair of DisplayPort outputs at up to 3840×2160 at 60 Hz. For analysts or operators running dual-screen workstation setups, this eliminates the resolution or refresh-rate compromise common in lower-tier secure KVM products. The two 20-pin DisplayPort Female host connectors are the active interface — verify your source machines have native DP output before ordering.
• Three USB 2.0 Console Ports: The console side provides three USB 2.0 Type-A ports, giving you flexibility to connect a keyboard, mouse, and one additional USB peripheral (such as a CAC reader) without a hub — a practical configuration for government desktop environments where smart card readers are standard issue.
• Metal Enclosure, USA-Made: The all-metal chassis at 8.8 × 6.7 × 2.6 in (224 × 170 × 67 mm) and 3.9 lb is built to sit on a desk or in a secure work area without flexing. Country of origin is the United States, which matters for TAA compliance reviews and procurement officers sourcing for federal agencies.
• Controlled Operating Environment: Rated for 0°C to 40°C operating and -20°C to 60°C storage at up to 80% RH — appropriate for standard office and data center environments. This is not a ruggedized field unit; deploy it in a climate-controlled workspace.
• 3-Year Manufacturer Warranty: StarTech backs the CK4-PM102C with a three-year warranty, which aligns with typical government and enterprise procurement cycles without requiring an extended service contract to cover the asset life.

Integration and Compatibility

The CK4-PM102C (often searched as CK4 PM102C) requires host computers with native DisplayPort output — active or passive DP-to-HDMI adapters are generally not permitted in NIAP-certified configurations, as they can introduce unvalidated hardware into the signal path. Confirm your source machines expose 20-pin DisplayPort connectors directly. USB peripheral sharing is limited to USB 2.0 speeds on the console side, so high-bandwidth USB 3.x storage devices will not function at full speed through this switch — plan accordingly for any peripheral that relies on USB 3.x bandwidth.

Frequently Asked Questions

Q: What NIAP certification level does the CK4-PM102C hold?

A: The CK4-PM102C is certified to NIAP Protection Profile for Peripheral Sharing Devices version 4.0 (PSD 4.0), the current applicable standard for secure KVM switches used on classified and government networks.

Q: What is the maximum display resolution supported?

A: The CK4-PM102C supports up to 4K at 60Hz (3840×2160 @ 60Hz) per DisplayPort output on both host ports.

Q: How many monitors can be connected per host computer?

A: Each of the two host ports supports a dual-monitor configuration — two DisplayPort monitors per host, four total displays connected to the switch at once.

Q: Is the CK4-PM102C manufactured in the United States?

A: Yes. Country of origin is listed as USA, which supports TAA compliance requirements for federal procurement.

Q: What USB peripherals can be shared through the console ports?

A: The console side has three USB 2.0 Type-A ports — sufficient for a keyboard, mouse, and one additional device such as a CAC/smart card reader. USB 3.x devices will operate at USB 2.0 speeds only.

Q: What is the warranty on the CK4-PM102C?

A: StarTech provides a 3-year manufacturer warranty on the CK4-PM102C.

Marty Allison

The spec that defines whether the CK4-PM102C belongs in your procurement list is NIAP PSD 4.0 — not the 4K resolution or the dual-monitor support, though both are genuinely useful. Most government and defense integrators I work with are dealing with procurement offices that require a current NIAP listing on the evaluated products list (EPL) before a secure KVM will be approved for classified network use. The CK4-PM102C clears that bar, and the USA country of origin handles TAA at the same time.

Technical Highlights:

• NIAP PSD 4.0: Current-generation certification — not PSD 3.0 legacy — meaning the device passed the stricter isolation and anti-tampering validation requirements introduced in the updated protection profile.
• Dual DisplayPort at 4K 60Hz: Two 20-pin DisplayPort Female host connectors per port, each capable of driving two monitors at 3840×2160 @ 60Hz. Operators with side-by-side workstation setups get full-resolution output without downscaling.
• Three USB 2.0 Console Ports: Practical layout for keyboard + mouse + CAC reader without an add-on hub — important in secure facilities where unapproved USB hubs may not pass physical security review.

Deployment Considerations:

• Verify host machines expose native 20-pin DisplayPort output. Adapter chains (DP-to-HDMI, then back) are not recommended in NIAP-validated configurations and may void the certification posture of the installation.
• The console USB ports are USB 2.0 only — any peripheral that depends on USB 3.x bandwidth (external SSDs, high-speed capture devices) will be throttled or non-functional through the switch.

The CK4-PM102C is the right call for dual-screen analyst workstations in SCIFs, federal agency secure rooms, or defense contractor facilities where NIAP PSD 4.0 and TAA compliance are explicit procurement requirements — not optional checkboxes.
