4K HDMI 1x4 Splitter for Multi-Room Viewing

This powered splitter duplicates a single HDMI source across four displays simultaneously. It supports video resolutions up to 3840 x 2160 at 30 Hz with 600 MHz bandwidth. The unit handles HDCP 1.4b and deep colour at 8, 10 or 12-bit. Audio formats include DTS-HD, Dolby TrueHD, DTS, Dolby-AC3 and DSD. It is suited for users needing identical content on multiple screens in home or commercial settings.

Plug-and-Play Installation with Resolution Limits

Connect the source to the single HDMI input and up to four displays to the HDMI outputs using standard cables; the device draws power from the included supply. No drivers or software configuration are required for basic operation. The splitter mirrors content only and cannot extend a desktop across screens. All connected outputs display the same resolution, defaulting to the lowest common capability among attached displays.

Verify Source Output and Cable Lengths Before Buying

Ensure your source device can output at 30 Hz for 4K resolution, as 4K at 60 Hz is not supported and will fall back to 1080p. Confirm that your HDMI cables are rated for the required bandwidth over the intended run lengths. The splitter does not support HDCP 2.2, so protected 4K content from newer streaming services or disc players may not display. Check that your displays accept the mirrored signal format.

Questions about this item

How can I confirm the AUBEAMTO 1x4 splitter is passing a 4K signal correctly after connecting it?

Check that each of the four connected displays shows an identical 3840x2160 image at 30 Hz and that audio plays through the HDMI speakers or soundbar without dropouts.

What comes in the box with the AUBEAMTO 4K HDMI Splitter 1x4 and what must I provide myself?

The package includes the powered splitter unit; you must supply the HDMI cables for the single input and four outputs, plus the power adapter if it is not integrated.

Which resolution and refresh-rate combination should I select on my source device for the AUBEAMTO 1x4 splitter?

Set the source to 3840x2160 at 30 Hz; the splitter does not support 4K at 60 Hz or HDCP 2.2, so higher refresh rates will fall back to 1080p.
