Triple-monitor KVM switch

The ESTONE SW231-3HD lets two computers share three HDMI monitors and four USB 3.0 peripherals with a single keyboard and mouse. It is aimed at professionals and enthusiasts who need simultaneous extended or mirrored desktops across three screens without unplugging cables. The unit ships with two USB 3.0 cables, a wired remote button, a 12V/1A power adapter and a user manual.

8K60 over HDMI 2.1

Each of the three monitor outputs supports up to 8K at 60 Hz and is backward compatible with 4K at 120 Hz and lower resolutions. HDMI 2.1 and HDCP 2.3 compliance means protected content plays correctly, but 8K60 output requires both the source graphics card and the display to support that mode.

USB 3.0 hub and switching

Four USB 3.0 ports run at up to 5 Gbps and accept keyboards, mice, printers, scanners or storage devices, while remaining compatible with USB 2.0 and 1.1 gear. Switching between the two connected PCs is done by front-panel push buttons or the included desktop controller; an auto-scan mode cycles every 3 seconds and LED indicators show the active port. The switch needs its own power adapter for stable operation with high-draw USB devices.

Questions about this item

What does the 8K 60Hz rating mean when I connect three monitors?

Each of the three HDMI outputs can deliver up to 8K at 60 Hz, but only if both the source graphics card and the attached monitor support that resolution and refresh rate.

Which HDMI standard does the switch implement and what bandwidth ceiling does it impose?

The unit follows HDMI 2.1 and HDCP 2.3, capping video bandwidth at the level required for 8K 60 Hz or 4K 120 Hz signals.

How much desk space does the switch occupy and what mounting options exist?

The chassis measures 5.43 by 5.35 by 1.46 inches and weighs 9.52 ounces; it sits flat on the desk and includes a wired push-button controller for remote switching.
