IOGEAR GCS1944 (DisplayPort / 4 Computers / Dual-View / 4K@60Hz / ~$320) Review
The IOGEAR GCS1944 is a 4-port DisplayPort KVM switch supporting dual-view (two monitors), 4K@60Hz, a 2-port USB 3.1 hub, and 7.1 surround audio switching for ~$320.
Dual-view support sets this apart from most 4-port switches in its price range, letting a single switch drive two monitors across four computers rather than forcing a single-monitor workflow. The USB 3.1 hub ports matter for anyone moving files via an external drive between machines, since USB 2.0-only competitors bottleneck large transfers noticeably. TAA compliance and front-panel button switching alongside hotkeys make it a fit for both home and light institutional deployments. Versus the TESmart HKS801-P23 — that offers double the port count for single-monitor setups, worth it for buyers who don't need dual-view. Versus the StarTech SV431DPU3A2 — that's rack-mountable, worth it for server-room deployments over a desktop setup.
