Four-Computer 4K KVMP Switch

The IOGEAR GCS1934H lets one keyboard, one mouse, one 4K HDMI display and shared audio control four separate computers. It supports Cinema 4K resolution at 4096 x 2160 and 60 Hz refresh with HDCP 2.2 and HDR. Two front-and-rear USB 3.1 Gen 1 Type A ports provide 5 Gbps peripheral sharing. TAA compliance suits government or institutional procurement.

Check HDMI And USB Ports Before Ordering

Each connected computer must supply an HDMI video output and a USB 3.1 Gen 1 Type B port for keyboard and mouse signals. Audio from each system uses a 3.5 mm jack. The console side requires one HDMI monitor input plus separate USB 2.0 Type A ports for keyboard and mouse. A DC 5 V power adapter is included and must be connected.

Replaces Separate KVM And Hub Setups

This unit consolidates a four-port KVM, a two-port USB 3.1 hub and an audio mixer into one chassis. Switching is done by pushbutton, hotkey, RS-232 command or mouse emulation with autoscan intervals from 5 to 99 seconds. It is not for users who need more than four computer ports or who require DisplayPort or USB-C video inputs.

Questions about this item

What cables and accessories are included with the GCS1934H, and what must I buy separately?

The box contains the switch, four 6 ft HDMI cables, four 6 ft USB 3.0 cables, four 6 ft audio cable sets, a power adapter and a quick-start guide. No extra cables are required for a typical four-computer setup.

Should I choose this 4-port model or a different capacity for my four workstations?

This unit provides exactly four computer ports with matching HDMI, USB 3.1 Gen1 Type-B and 3.5 mm audio connectors, so it fits a four-workstation desk without unused ports.

What does the 4096 x 2160 @ 60 Hz Cinema 4K rating mean when I connect my monitor?

The switch passes a true 4096 x 2160 signal at 60 Hz with HDCP 2.2 and HDR support, so a compatible monitor will display full Cinema 4K resolution without downscaling.
