1×2 HDMI mirror splitter

This powered HDMI splitter takes one source and duplicates it across two displays, delivering identical video and audio on both screens. It is designed for users who need a mirrored setup rather than an extended desktop. The unit draws power through an included USB cable and requires no driver installation. It suits home theatre, digital signage or presentation scenarios where the same content must appear on two screens simultaneously.

4K at 30 Hz maximum

The splitter supports resolutions up to 3840 × 2160 at a 30 Hz refresh rate, along with Full HD 1080p, 720p and standard-definition timings down to 480i. It is compliant with HDMI 1.3 and 1.4 and HDCP 1.4, but does not support HDCP 2.2, so protected 4K content requiring that version will not pass through. Deep colour up to 36 bit and multi-channel audio formats including LPCM 7.1 and DTS-HD are handled within this bandwidth limit.

Passive cooling, USB powered

The compact aluminium enclosure measures 6.3 × 5.3 × 1.2 cm and dissipates heat without a fan, so operation is silent in normal use. Power consumption is low enough to be supplied from a standard USB port, eliminating the need for an external 110 V adapter. The supplier suggests using HDMI cables no longer than 25 ft for reliable signal integrity at the highest resolutions.

Questions about this item

Does the 4K@30Hz rating mean both connected screens show the same 4K image at 30 frames per second?

Yes, the splitter mirrors the source so each display receives an identical 3840x2160 signal at up to 30Hz.

The box says HDMI 1.4 and HDCP 1.4 — what does that cap in practice?

It limits 4K output to 30Hz and blocks HDCP 2.2 content, so 4K@60Hz or newer protected streams will not pass through.

What does the unit need for power and mounting?

It draws power from the included USB-micro cable and measures 6.3×5.3×1.2 cm, so it sits on a desk or tapes behind a display without brackets.
