IOGEAR GCS1204 (USB DisplayPort / 4 Computers / 4K@30Hz / Audio / ~$210) Review
The IOGEAR GCS1204 is a 4-port DisplayPort KVM switch with 4K@30Hz support, a 2-port USB 2.0 hub, and audio switching for ~$210.
This switch fills the gap between IOGEAR's 2-port DisplayPort models and its pricier dual-view GCS1944, giving buyers four-computer switching on a single monitor without paying for dual-view they don't need. Sticking with USB 2.0 rather than 3.0 hub ports is the main cost-saving tradeoff here, fine for keyboards, mice, and basic peripherals but a bottleneck for external storage transfers. Versus the IOGEAR GCS1944 — that adds dual-view and 4K@60Hz for a higher price, worth it for buyers needing two monitors. Versus the StarTech SV431DPU3A2 — that adds USB 3.0 and rack-mount ears, worth it for server-room deployment.
