Two-port 4K Dual View KVM

The IOGEAR GCS1942 is a DisplayPort KVM switch that lets one keyboard, one mouse and two monitors control two computers. It targets professionals who need true Cinema 4K resolution across dual displays while sharing USB 3.0 peripherals and analogue audio between workstations.

Sustained load behaviour

The unit operates continuously between 0 and 40 °C with humidity up to 80 % non-condensing, drawing power from an external 12 V DC adapter. LED indicators show on-line and selected status for each port, while AutoScan cycles through connected PCs at intervals from 1 to 255 seconds without interrupting video at 4096 x 2160 @60 Hz.

Installation and common issues

All required cables — four DisplayPort, two USB 3.0, two audio sets — are included in the box, so no extra purchases are needed for a typical dual-monitor setup. Firmware updates add features over time, but users must ensure both computers output 4096 x 2160 @60 Hz over DisplayPort; systems limited to lower resolutions or different video interfaces will not work.

Questions about this item

How much heat does the GCS1942 produce when left on continuously?

The switch is rated for 0 to 40 °C ambient temperature and draws 12 V DC power; it has no fan, so it runs silently and adds minimal heat to a closed rack.

Which cables and peripherals must I already have to use both DisplayPort monitors and USB 3.0 devices?

All four DisplayPort cables, two USB 3.0 cables and two audio cable sets are included; you only need two DisplayPort sources, a keyboard, a mouse and up to two USB 3.0 peripherals.

Will the GCS1942 pass 7.1 surround sound from an older PC that only has 3.5 mm analogue jacks?

Yes — each computer connects via its green and pink 3.5 mm jacks, and the console side provides front and rear 3.5 mm ports for speakers and microphone, preserving 7.1 audio.
