Purpose and user

The ESTONE OZQ8AB3 is an HDMI 2.1 bi-directional switch that lets you connect two source devices to one display or one source to two displays. It handles 8K at 60Hz and 4K at 120Hz with 48Gbps bandwidth and supports VRR and Dynamic HDR. Gamers and home-theatre users who need to share a single high-bandwidth HDMI 2.1 input will find it useful.

Who it suits and who it does not

This unit suits setups that require manual switching between a console, PC or media player on a modern TV or monitor. It does not serve users who want automatic input detection or simultaneous output on two screens. Buyers needing longer cable runs than 1.5 metres for 8K or 3 metres for 4K should plan around those limits.

Deciding specification

The key figure is the maximum cable length allowed for each resolution tier: 1.5 metres for 8K at 60Hz, 3 metres for 4K at 120Hz and up to 8 metres for 1080P at 240Hz. If your installation exceeds these distances at the target resolution, the signal will not meet the rated performance.

Questions about this item

What cable length limit applies first when running 8K@60Hz through this switch?

The 8K@60Hz signal is only guaranteed up to 1.5 metres (4.9 ft) per cable run.

How much power does the switch draw and does it get warm during all-day use?

It is powered by the included USB-C cable and has no fan, so it runs silently with negligible heat.

Which HDMI cables and source devices must I already own to use this bi-directional switch?

You need HDMI 2.1 cables rated for 48 Gbps (not included) and sources that output 8K@60Hz or 4K@120Hz.
