ATEN CS1922 (2-Port USB-C KVM Switch / 4096x2160@60Hz or 2560x1440@144Hz / 2-Port USB 3.1 Gen1 Hub / Button + Hotkey) Review

The ATEN CS1922 is a professional-grade 2-port USB-C KVM switch supporting 4096x2160@60Hz or 2560x1440@144Hz, with a built-in 2-port USB 3.1 Gen1 hub and both button and hotkey switching.

ATEN is one of the longest-standing names in KVM switching, and the CS1922 is a clean 2-port USB-C switch aimed at people running two computers off one monitor/keyboard/mouse setup, commonly a work laptop and a personal desktop. The headline spec is display flexibility, it'll do a single 4K60 display or step down to 1440p144 if you're prioritizing refresh rate over resolution, useful if one of your two machines is used for anything remotely game-adjacent. The built-in 2-port USB 3.1 hub means you're not sacrificing all your USB ports to the switch itself, you get some pass-through capacity for a webcam or drive on top of keyboard and mouse.

Resolution vs Refresh Rate Choice

Not every KVM switch lets you choose between max resolution and max refresh rate, many just cap out at a fixed spec. The CS1922 supporting both 4K60 and 1440p144 as selectable targets is a meaningfully more flexible spec sheet for anyone whose two machines have different display priorities.

Comparison to Alternatives

Against our IOGEAR GCS1932H and TESmart HKS0401A1U (both HDMI-based multi-port switches), the ATEN is USB-C native and 2-port only, a more modern, more focused tool for exactly two machines rather than a larger multi-source hub. Against our CKL 622DP, similarly a 2-port switch, ATEN's brand reputation and refresh-rate flexibility are the differentiators, generally at a higher price point.
