Four-Computer Dual-Monitor KVM

The IOGEAR GCS1944 lets a single keyboard, mouse and two DisplayPort monitors control four separate computers. It targets professionals who need simultaneous access to multiple workstations without duplicating peripherals. The switch includes a built-in USB 3.0 hub and analogue audio routing for speakers and microphones. All required cables and a power adapter ship in the box.

DisplayPort 1.2 Bandwidth Limits

Video tops out at 4096 x 2160 at 60 Hz per monitor, matching the DisplayPort 1.2 and HDCP specifications listed. Higher refresh rates, deeper colour depths or resolutions beyond 4K DCI are not supported by this hardware. The USB hub operates at 3.0 speeds, so 3.1 or 3.2 devices will fall back to 3.0 throughput. Auto-scan dwell time ranges from 1 to 255 seconds.

Front-Panel Buttons And Cable Routing

Switching is done with push buttons on the unit; no software driver is required for basic operation. Eight DisplayPort cables, four USB 3.0 cables and four audio cable sets must be routed to the four host PCs, which can create clutter behind the desk. Buyers who need single-monitor setups or more than four computers will find this model unsuitable.

Questions about this item

Should I pick this four-port model or a smaller KVM for my four DisplayPort computers?

The GCS1944 provides exactly four DisplayPort and four USB 3.0 Type B inputs, so one switch handles all four PCs with a single keyboard, mouse and dual monitors.

What does the 4096 x 2160 @60 Hz rating deliver on my actual dual-monitor desk?

Each console DisplayPort output can drive Cinema 4K at 60 Hz, giving two independent 4096 x 2160 workspaces without scaling or refresh compromise.

How does the DisplayPort 1.2 interface limit what I can run?

DisplayPort 1.2 caps each video channel at 4096 x 2160 @60 Hz and carries the USB 3.0 hub and audio paths, so higher resolutions or refresh rates are not supported.
