ATEN UH3238 USB-C Dual Monitor Dock (USB-C / 7 Ports / 90W Host Charging / Dual 4K@60Hz / Fanless with KVM Switching / Windows/Mac / ~$180) Review
The ATEN UH3238 is a fanless USB-C dual monitor dock from a manufacturer better known for KVM switches, and it carries that heritage over with a physical switch button that toggles the connected keyboard, mouse, and displays between two source computers.
ATEN's core business is KVM switches, boxes that let one keyboard, mouse, and monitor set control multiple computers, and the UH3238 folds a simplified version of that into a docking station. A single button lets two laptops share the same monitors, keyboard, and mouse without unplugging anything, which is a genuinely different use case from every other dock in this catalog. The fully fanless design also means silent operation on a quiet desk.
Comparison to Alternatives
Against the Dell WD19S, both are modest dual-4K-capable USB-C docks, but the ATEN's KVM-style switch button lets two computers share the same dock and displays, something the Dell dock has no equivalent for. Against the Kensington SD1620P, the Kensington is smaller and more travel-focused, while the ATEN targets a fixed two-computer desk setup where source switching matters more than portability.
