4x1 HDMI KVM Multiviewer for Multi-Source Display

The ESTONE OZK6 is a 4x1 HDMI KVM multiviewer that shows up to four HDMI sources on one screen. It supports five viewing modes including quad-split and full-screen switching. Built for meeting halls, security monitoring and multi-system workstations, it handles 4K at 30 Hz and 1080p at 60 Hz. Control is via front-panel buttons, IR remote or USB KVM commands.

Check HDMI 1.4 Compatibility and Cable Lengths

Verify that each source outputs HDMI 1.4b with HDCP 1.4 and that your display accepts 3840 x 2160 at 30 Hz or 1080p at 60 Hz. Input cables must not exceed 15 metres using AWG26 HDMI 1.4b cable; the output run must stay under 24 metres with the same cable grade. The unit provides four USB 2.0 ports for KVM peripheral sharing, so confirm your keyboard and mouse are USB 2.0 compatible.

Passive Cooling with External USB Power

The metal enclosure dissipates heat without a fan, so operation is silent in normal use. Power comes from the included USB power adapter, drawing 5 V over USB rather than a proprietary supply. Maximum bandwidth is 330 MHz with a 10.2 Gbps baud rate, and audio output is limited to PCM2 stereo. No internal power supply or active cooling means minimal ongoing power draw.

Questions about this item

Does the box include HDMI cables or must they be purchased separately?

The package contains the multiviewer, a USB power adapter, four USB data cables, an IR remote and a user manual. HDMI cables are not included and must be bought separately.

Which resolution and refresh rate combination should I choose for four 4K sources?

The unit supports 3840 x 2160 at 30 Hz per input; 1080p at 60 Hz is also available if higher refresh rates are needed.

What does the 4K@30Hz headline figure mean when four sources are displayed together?

Each of the four HDMI 1.4 inputs can carry 4K at 30 Hz, and the multiviewer combines them into a single 4K@30Hz output using one of five screen-segmentation modes.
