1×4 HDMI Splitter for Mirrored Displays

The Bailink BL-HDMISP takes a single HDMI source and duplicates it across four screens simultaneously. It is built for users who need the same 4K or Full HD image on multiple TVs, monitors or projectors at once. The aluminium housing aids heat dissipation during continuous use. It does not extend a desktop across displays.

Plug-and-Play Setup with USB Power

Connect the source, attach up to four displays with standard HDMI cables, then plug the supplied USB power cable into any 5 V port. Gold-plated connectors resist corrosion from repeated insertion. The only common issue is forgetting the USB power link, which leaves outputs blank or unstable. No drivers or configuration are required.

4K at 30 Hz Bandwidth Limit

The splitter complies with HDMI 1.4, so the maximum 4K rate is 30 Hz; 1080p reaches 60 Hz. Deep-colour 480i, 576i, 480p, 576p, 720p, 1080i and 1080p are all supported. HDCP 1.0 through 1.4 is handled, but later HDCP versions are not. Audio passes through LPCM, Dolby-AC3, DTS 7.1 and high-bitrate formats without change.

Questions about this item

How do I confirm the BL-HDMISP is duplicating the signal to all four displays at 4K 30 Hz?

Connect a 4K source to the single HDMI input and four displays to the HDMI outputs; each screen will show the identical 3840x2160@30Hz image, confirming mirror mode is active.

What comes in the box and which cables must I supply?

The package includes the splitter, a USB power cable and a user manual; you must provide one HDMI cable for the source and up to four HDMI cables for the displays.

Which version should I choose if my source only outputs 1080p at 60 Hz?

The BL-HDMISP is a single 1×4 model that handles 1080p@60Hz natively, so no alternate version or capacity is required.
