ATEN CS1144DP4 (4-Port 4K Secure DisplayPort KVM Switch / NIAP PP4.0 / $710.47) Review

The ATEN CS1144DP4 is a 4-port secure DisplayPort KVM switch built to next-generation NIAP PP4.0 requirements, supporting 4K@30Hz resolution with fully isolated per-channel video buffers and pushbutton-only switching, priced at $710.47.

The CS1144DP4 doubles the CS1142DP4's channel count to four while keeping the same 4K@30Hz resolution and next-gen NIAP PP4.0 certification, making it the mid-size option for classified desks that need both higher resolution and access to more than two domains. Versus the ATEN CS1142DP4 — half the channels for meaningfully less money, right-sized for a two-domain 4K desk. Versus the ATEN CS1184DP4 — same 4-port count on the older, cheaper 1080p-class platform.

4K Resolution Across Four Secure Channels

The CS1144DP4 doubles the CS1142DP4's channel count to four while keeping the same 4K@30Hz resolution and next-gen NIAP PP4.0 certification.

The Mid-Size 4K Secure Option

It's the mid-size option for classified desks that need both higher resolution and access to more than two domains, without stepping up to the 8-port CS1148DP4.

Comparison to Alternatives

Versus the ATEN CS1142DP4 — half the channels for meaningfully less money, right-sized for a two-domain 4K desk. Versus the ATEN CS1184DP4 — same 4-port count on the older, cheaper 1080p-class platform.

Expert Review

Expert rating8.6 / 10

A strong middle ground in ATEN's 4K-capable secure switch line, balancing resolution and channel count.

Best for

  • Four-domain secure desks needing 4K resolution
  • Government facilities upgrading their secure KVM fleet to 4K
  • Workstations that outgrew a 2-port 4K secure switch

Not for

  • Two-domain desks better served by the cheaper CS1142DP4
  • Budget deployments where 1080p is sufficient (see the CS1184DP4)
  • Deployments needing 8 secure channels (see the CS1148DP4)
