ESTONE OZK3-1 2×2 HDMI KVM Matrix
This 2-in-2-out HDMI 2.0b matrix lets two computers share one keyboard, one mouse and two monitors. It supports 4K at 60 Hz and 1080p at 144 Hz with HDCP 2.3 compliance. The aluminium-alloy chassis measures 176 × 51 × 21 mm and weighs 9.52 ounces. It is aimed at desk setups that need simultaneous dual-display access to two hosts.
Bundled cables and remote
The package includes two USB data cables, one USB power cable, an IR remote control (AAA battery not supplied) and a user manual. These let you connect both computers and power the unit without extra purchases. The remote adds desk-distance switching alongside the front-panel push buttons and hot-key commands. No software installation is required on Windows XP, 7, 10, macOS, Linux or Unix.
HDMI 2.0 bandwidth limits
HDMI 2.0b caps video at 4K 60 Hz 4:4:4 or 1080p 144 Hz; higher refresh rates at 4K or HDR metadata beyond HDCP 2.3 are not supported. The matrix does not convert DisplayPort or DVI signals natively — passive adapters work only when the source outputs HDMI-compatible TMDS. USB 3.0 peripheral ports share the 5 Gbps bus, so sustained throughput drops when multiple high-speed devices are active.

Questions about this item
Will the IR remote need new batteries after a while?
The IR remote ships without AAA batteries; you will need to supply and replace them yourself.
What is the maximum refresh rate the HDMI 2.0 outputs can sustain at 1080p?
The switch supports 1080p at 144 Hz through its HDMI 2.0 ports.
How warm does the aluminium alloy enclosure get during all-day operation?
The aluminium alloy shell acts as a passive heatsink, so the unit runs warm but stays within normal operating temperatures without a fan.
