One-to-two 4K splitter for dual displays

The AUBEAMTO HDMI splitter takes a single HDMI source and duplicates it to two displays simultaneously. It supports resolutions up to 3840 x 2160 at 30 Hz, plus 1080p at 60 Hz and 3D content. The unit includes a 5 V power adapter for signal amplification and deep colour 36-bit support. Input cables can reach 5 m at 1080p, while output cables can run up to 10 m.

Suits mirroring setups not multi-monitor desktops

This splitter is built for owners who want the same picture on two screens — living-room TV plus bedroom TV, projector plus monitor, or console feeding two displays. It does not extend a desktop across monitors, so users needing independent screens should look at a graphics card with multiple outputs or a DisplayPort MST hub. The device also will not bypass HDCP 1.3 protection, so protected streams that require HDCP 2.2 may not play.

4K at 30 Hz ceiling decides fit

The maximum supported resolution is 3840 x 2160 at 30 Hz. If your source and displays both run 4K at 60 Hz, this splitter will drop the refresh rate. Buyers needing 4K 60 Hz pass-through should choose a splitter rated for that bandwidth.

Questions about this item

Does the box include the power adapter or do I need to buy one separately?

The package contains the 1×2 HDMI splitter and a 5 V power adapter, so no separate purchase is required.

I see 4K@30 Hz and 1080P@60 Hz listed — which resolution should I pick for my setup?

Choose 4K@30 Hz when both displays support 3840×2160, or 1080P@60 Hz for smoother motion on Full HD screens.

The spec says input cable ≤ 5 m and output cable ≤ 10 m at 1080P — what happens if I run longer cables at 4K?

At 4K@30 Hz the reliable distance is shorter; keep input cables under 5 m and output cables under 10 m to avoid signal degradation.
