Dual-monitor 8K KVM

The ESTONE SW221-2HD is a two-port HDMI 2.1 KVM switch built for users who operate two computers and want to share one keyboard, one mouse and two monitors. It suits home-office workers, developers and streamers who need simultaneous dual-display output at up to 8K 60 Hz or 4K 120 Hz without re-plugging cables.

Installation and common issues

The unit is plug-and-play on Windows, macOS, Linux and Unix; simply connect the two supplied USB 3.0 data cables, the HDMI leads and the DC power adapter, then use the front push-buttons or the wired desktop controller to switch sources. A frequent oversight is forgetting the external power supply, which is required for stable 8K signal integrity and USB 3.0 hub operation.

Deciding specification

The decisive figure is the dual HDMI 2.1 output supporting 8K at 60 Hz and 4K at 120 Hz, which determines whether the switch can drive your chosen monitors at their native resolution and refresh rate.

Questions about this item

How can I confirm the switch is passing 8K 60Hz video to both monitors after connecting two PCs?

Verify each display reports 8K 60Hz in its on-screen menu or OS display settings, and check that the front-panel LED for the active port is lit while the other is off.

Which cables and adapters are included and what must I supply to run two computers with dual monitors?

The box contains the KVM unit, two USB 3.0 data cables, a DC power adapter and a user manual; you must provide four HDMI 2.1 cables (two per computer) and your own keyboard, mouse and USB peripherals.

Should I choose the 8K 60Hz or 4K 120Hz capability for competitive gaming on a 120 Hz panel?

Select 4K 120Hz for high-refresh gaming; the switch supports 4K at 120 Hz and 8K at 60 Hz simultaneously, so pick the mode that matches your monitor's native timing.
