Four-Port HDMI Splitter for 4K Displays

This Rocstor Y10C294B1 splits one HDMI source to four screens simultaneously. It handles 4K resolution at 60Hz with HDR and 4:4:4 chroma subsampling. The unit is built for installers and multi-monitor users who need identical output across every display.

Passive Cooling and Low Power Draw

A metal enclosure dissipates heat without a fan, so the device runs silently in normal use. The included 5V 1A adapter keeps power consumption modest. HDCP 2.2 and HDMI 2.0 compliance ensure stable handshake with protected content.

Replaces Single-Output Cables or Basic Switches

The jump is worth it when you must mirror one source to four 4K 60Hz displays at once. It does not suit setups that need independent content on each screen or more than four outputs. Plug-and-play operation means no driver installation is required.

Questions about this item

How do I connect the Rocstor Y10C294B1 splitter and what step do people often miss?

Connect one HDMI source to the single input, then link up to four displays to the outputs, and plug in the included 5V 1A power adapter — the step many skip is powering the unit before expecting a signal.

What maintenance or replacement will the Y10C294B1 need over time?

The metal enclosure needs no routine service; only the external 5V 1A power adapter may require replacement if it fails after extended use.

What limit appears first when the splitter runs continuously at 4K 60Hz?

The 18Gbps bandwidth ceiling and HDMI 2.0 specification cap sustained 4K 60Hz 4:4:4 transmission, so longer cable runs or marginal cables will hit that limit first.
