1x4 HDMI Splitter for Multi-Display Mirroring

The ESTONE OZF4C duplicates a single HDMI source across four screens at up to 3840x2160 resolution. It transmits video and audio simultaneously with HDCP 1.4 support. The unit requires the included 5V power adapter for stable operation. This splitter mirrors content only and does not extend the desktop.

Check Source Device and Cable Limits

Verify your source outputs 3840x2160 at 30 Hz or a compatible lower rate such as 1080p at 60 Hz. The splitter does not support HDCP 2.2, so protected 4K streams may not display. All four attached displays will show the identical image. Ensure HDMI cables are rated for the chosen resolution and distance.

Bundled Power Adapter and Manual Enable Setup

The included 5V/1A power adapter supplies the active circuitry needed for four simultaneous outputs. Without it, signal loss or dropout is likely across longer cable runs. The user manual provides connection diagrams for sources such as consoles, PCs, and streaming sticks. No software or drivers are required for operation.

Questions about this item

Does the ESTONE OZF4C package include everything needed to connect four displays, or must I buy extra cables or power supplies?

The box contains the 1×4 HDMI splitter, a 5 V/1 A power adapter and a user manual. You will need to supply four HDMI cables to reach your monitors or projectors.

The specifications list 4K at 30 Hz and 1080p at 60 Hz — which resolution and refresh combination should I pick for a 4K monitor?

Choose 3840×2160 at 30 Hz for native 4K output; the splitter cannot exceed 30 Hz at that resolution. If you need 60 Hz, run the display at 1080p instead.

What does the 3840×2160@30Hz rating mean when the splitter is connected to a PC and four 4K screens?

All four screens will show an identical 4K image at up to 30 frames per second; the device duplicates the signal and does not support extended desktop mode.
