Tripp Lite B004-DPUA2-K 2-Port DisplayPort KVM Switch with Audio, Cables and USB 3.0 Hub Review

Tripp Lite B004-DPUA2-K 2-port DisplayPort KVM switch with 4K support, USB 3.0 hub, audio switching, and included cable sets for modern dual-computer desktops.

The B004-DPUA2-K brings Tripp Lite's included-cables approach to a modern DisplayPort setup, supporting full 4K at 60Hz between two computers along with a 3-port USB 3.0 hub for fast external drives and accessories. Like the B004-VUA2-K-R, the necessary DisplayPort and USB cable sets are in the box, so there's no separate purchase needed to get a complete two-computer switch up and running. Audio switches automatically with the active display and USB source, and the USB 3.0 hub ports mean peripheral transfer speeds don't bottleneck behind older USB 2.0 KVM designs.

Modern 4K DisplayPort Support

Full 4096x2160 at 60Hz keeps this switch relevant for current high-resolution monitors, a step up from Tripp Lite's VGA-based B004-VUA2-K-R and B032-VU2 models, and matched against ATEN's DisplayPort lineup like the CS1922 and CS1924A.

USB 3.0 Hub Throughput

The 3-port USB 3.0 hub is a meaningful upgrade over USB 2.0 KVM hubs for anyone connecting external SSDs or high-bandwidth peripherals that need to follow the active computer.

Comparison to Alternatives

Against ATEN's CS1924A (4-port DisplayPort), the B004-DPUA2-K covers half the port count but adds a faster USB 3.0 hub and bundled cables, making it a stronger fit for a simple 2-PC high-performance desk. Compared to its sibling B004-DP2UA2-K, this model drives one shared display rather than dual independent displays per computer.
