StarTech CK4-P202 Secure 2-Port Dual-Monitor DisplayPort KVM Switch

Overview

The StarTech CK4-P202 is a NIAP Protection Profile 4.0-certified, 2-port secure KVM switch designed for dual-monitor DisplayPort workstations where data isolation between networks is a compliance requirement — not a preference. Built for government workstations, secure operations centers, defense contractors, and enterprise environments handling classified or sensitive data, this switch lets a single operator control two computers across two DisplayPort monitors without any data path between the connected systems. At 3.9 lb in an all-metal chassis and manufactured in the USA, the CK4-P202 is built to the physical security standards that classified deployments demand. If you need to share peripherals across two separate security domains on a dual-monitor desk, this is the architecture to consider.

Key Features

• NIAP Protection Profile 4.0 Certification: NIAP PSD 4.0 is the current benchmark for secure KVM switches used in U.S. government and defense environments. This certification means the device has been independently evaluated and validated against rigorous security assurance requirements — if your deployment requires NIAP-listed equipment, the CK4-P202 meets that bar without requiring a waiver or deviation.
• 4K 60Hz DisplayPort Output: Each of the two monitor outputs supports DisplayPort at 4K resolution, so operators working with high-density data displays, GIS mapping, or detailed imagery don't lose visual fidelity when switching between systems. Running 4K across both screens simultaneously keeps the workstation practical for professional workloads.
• Dual-Monitor Configuration: Two independent DisplayPort console outputs mean you can span your secure and non-secure network sessions across separate screens simultaneously — no toggling between full-screen modes. For analysts who need side-by-side visibility of two classification levels, this eliminates the workflow penalty of single-monitor KVMs.
• USB 2.0 Peripheral Sharing: Two USB 2.0 Type-A console ports handle keyboard and mouse switching between the two connected PCs. The USB interface is deliberately limited in scope — this is a security architecture choice, not a cost cut. Restricting the USB path reduces the attack surface for cross-domain data leakage.
• 4-Port DisplayPort Host Connectivity: Four 20-pin DisplayPort female connectors on the host side — two per PC — give you the full dual-monitor connection to each source computer. This is a dedicated connector per display per host, which avoids any shared video path that could become an unintended data channel.
• Analog Stereo Audio: 2-channel analog stereo audio support is included, allowing audio peripherals to be shared across the switch without requiring a separate audio selector. For environments where voice communication or media playback is part of the workstation workflow, this consolidates the peripheral count on the desk.
• All-Metal Chassis, USA Manufactured: The metal enclosure isn't just about durability — it contributes to RF shielding in environments where electromagnetic emanations are a concern. USA country of origin supports procurement requirements under TAA and relevant federal acquisition regulations.
• Compact Desktop Footprint: At 8.8 × 6.7 × 2.6 in and 3.9 lb, the CK4-P202 sits on the desk without dominating it. Secure KVM devices have historically been bulky; this form factor fits into standard government workstation configurations without requiring a dedicated shelf or rack unit.
• Operating Temperature 0°C to 40°C: Standard office and operations center temperature range — suited for climate-controlled secure facilities. Not rated for industrial or outdoor deployment, which is appropriate for its intended use case.

Integration and Compatibility

The CK4-P202 (often searched as CK4 P202) connects to any computer with a DisplayPort output and USB host port. With four 20-pin DisplayPort female connectors on the host side, it pairs with workstations running Windows, Linux, or other operating systems that expose standard DisplayPort and USB HID interfaces — no proprietary drivers are required for basic switching operation, which simplifies deployment in locked-down government IT environments where installing third-party software can trigger change-control reviews.

For organizations deploying across a KVM switch infrastructure in multi-domain secure facilities, the NIAP 4.0 certification aligns with the device selection requirements outlined in most agency IT security policies. Pair this switch with DisplayPort-capable workstations and USB keyboards and mice that are themselves approved for cross-domain use. If your environment uses CAC readers or other USB security tokens, confirm compatibility with your security office before deployment — the USB 2.0 ports support HID-class devices, but specific token support should be validated in your accreditation documentation.

Buyers evaluating broader secure KVM switch options for mixed single- and dual-monitor deployments, or those considering 4-port configurations, should review the full StarTech secure KVM line. For workstations requiring HDMI video rather than DisplayPort, a different model in the family is the appropriate selection — do not attempt to adapt with passive DP-to-HDMI converters in NIAP-certified configurations, as adapters are not part of the evaluated configuration.

Frequently Asked Questions

Q: What NIAP certification level does the CK4-P202 carry?

A: The CK4-P202 is certified to NIAP Protection Profile for Peripheral Sharing Devices (PSD) version 4.0 — the current standard for secure KVM switches used in U.S. government and defense deployments.

Q: How many monitors and computers does the CK4-P202 support?

A: It supports 2 computers (KVM ports) and 2 monitors (dual DisplayPort console outputs), giving you a full dual-monitor workspace with the ability to switch between two separate PCs or network domains.

Q: What is the maximum display resolution supported?

A: The CK4-P202 supports up to 4K at 60Hz over DisplayPort, so both connected monitors can run at full 4K resolution without downscaling.

Q: What is the warranty on the CK4-P202?

A: StarTech provides a 3-year manufacturer warranty on the CK4-P202.

Q: Is the CK4-P202 manufactured in the USA?

A: Yes. The CK4-P202 is manufactured in the USA, which supports TAA compliance requirements and relevant federal acquisition regulations.

Q: Can I use the CK4-P202 with HDMI monitors?

A: No. The CK4-P202 uses DisplayPort on both the host and console sides exclusively. Using passive DisplayPort-to-HDMI adapters is not part of the NIAP-evaluated configuration and is not recommended in certified deployments.

When I look at the CK4-P202, the spec that matters most in a classified deployment isn't the 4K resolution or the dual-monitor layout — it's the NIAP PSD 4.0 certification. That certification means this device has been through an independent evaluation against the current U.S. government security assurance standard for peripheral sharing. In environments where accreditation documentation drives procurement, buying a NIAP 4.0-listed device like the CK4-P202 is often the difference between a straightforward ATO process and a months-long waiver request.

Technical Highlights:

• NIAP PSD 4.0: The current (not legacy) protection profile — some older secure KVMs in the field are certified to PSD 3.0. Confirming 4.0 compliance up front avoids a device replacement cycle when your agency updates its approved products list.
• 4K 60Hz Dual DisplayPort: Both console outputs run at full 4K 60Hz — meaningful for analysts working with high-resolution imagery, geospatial tools, or dense data dashboards where downscaling to 1080p is a workflow problem, not just an aesthetic one.
• USA Manufacture, Metal Chassis: The all-metal enclosure supports RF containment, and domestic manufacture satisfies TAA and many agency supply chain requirements without additional documentation burden.

Deployment Considerations:

• Confirm that your keyboard and mouse are USB HID-class devices compatible with the two USB 2.0 Type-A console ports — some specialty input devices with proprietary USB protocols may not enumerate correctly through the restricted USB path, which is by design for security reasons.
• Do not deploy with DisplayPort-to-HDMI adapters between the KVM and your monitors — adapters are outside the evaluated configuration and will put your NIAP compliance posture at risk during any subsequent security assessment.

The CK4-P202 is the right call for a two-person or single-operator workstation in a Sensitive Compartmented Information Facility (SCIF) or similar controlled environment where the operator needs simultaneous dual-monitor visibility into two separate classification domains without any physical data path between them.
