ATEN CS1822 (2-Port USB HDMI KVMP Switch / 4K@30Hz / $317.63) Review
The ATEN CS1822 is a 2-port USB HDMI KVMP switch supporting 4K@30Hz, a 2-port USB 2.0 hub, and stereo audio switching, priced at $317.63.
The CS1822 is ATEN's entry point into HDMI KVM switching: two ports, 4K@30Hz, and the same hub and audio switching found across the CS18xx family, at the lowest price in the line. It's the switch to reach for when the job is simply sharing one 4K monitor and one keyboard/mouse between two machines without needing 60Hz smoothness. Versus the ATEN CS1842 — pay more for true 60Hz on the same 2-port layout. Versus the ATEN CS1824 — same 30Hz cap, doubles the ports for two extra machines.
