Two USB-C machines sharing one keyboard, one mouse, and one monitor sounds simple until you're unplugging cables every time you need to hop between them. The US3312-AT is a cable-based KVM switch that handles the switching for you. Push the remote port selector and both hosts swap in an instant. You get 4096 × 2160 at 60 Hz with 4:4:4 chroma — full colour depth, no compression artefacts on your design work or video edits. Two USB downstream ports and one DisplayPort keep your peripherals shared across both machines. ATEN Video DynaSync means the extended desktop windows don't snap back to defaults when you switch hosts. No drivers. No software. Plug it in and it works
