ATEN CM1942-AT-U 2-Port 4K DisplayPort Dual Display KVM Switch with USB 3.1 Gen 1 Hub

Two PCs. Two monitors. One desk that shouldn't need four keyboards and six cables running under it. The CM1942-AT-U handles both machines from a single USB/HDMI console, so you stop reaching for the right mouse and start doing the work.

You get true 4K DCI (4096 x 2160 @ 60 Hz) on each DisplayPort output — no scaling, no soft edges. Single PC Mode mirrors one machine across both screens. Dual PC Mode keeps two separate workspaces side by side regardless of which box you're typing into.

Boundless Switching means you drag the cursor past the screen edge and you're on the other PC. No hotkeys to memorise, no button hunting mid-deadline. The built-in 2-port USB 3.1 Gen 1 hub (5 Gbps) keeps your peripherals shared without re-plugging every time.

Built for the people running trading terminals, editing timelines, or juggling design comps who'd rather not waste a minute per switch
