1×4 HDMI Splitter for 4K Multi-Display

This ESTONE OZF3-2 unit takes a single HDMI source and mirrors it to four identical outputs at up to 3840 x 2160 resolution and 60 Hz refresh rate. It is built for installers, presenters or gamers who need the same ultra-high-definition picture on multiple screens simultaneously. The splitter handles HDCP 1.1, 1.2, 1.4 and 2.2 so protected content plays without handshake issues.

Passive Cooling and External Power

The aluminium enclosure dissipates heat without a fan, so operation stays silent in meeting rooms or home theatres. An included DC 5 V supply powers the internal amplification that drives four outputs at the full 18.2 Gbps bandwidth with zero transmission loss. Typical draw is low enough that the supplied adapter covers all normal use cases.

Mirror-Only Output Constraint

This device duplicates the input signal; it cannot extend a desktop or show different content on each display. All four connected screens must share the same resolution and refresh rate for stable operation. Buyers who need independent video streams or extended desktop modes should choose a matrix switch or multi-output graphics card instead.

Questions about this item

How do I install the ESTONE OZF3-2 splitter and what step is often missed?

Connect the included DC 5V power supply first, then link one source to the single HDMI input and up to four displays to the HDMI outputs. The step people skip is powering the unit before connecting cables, which causes no signal on the outputs.

What maintenance or replacement will the ESTONE OZF3-2 need over time?

The external DC 5V power adapter is the only part likely to need replacement. The splitter itself has no moving parts, no fan and no user-serviceable components, so normal use requires no scheduled maintenance.

What limit appears first when running the ESTONE OZF3-2 continuously at 4K 60Hz?

The 18.2Gbps bandwidth ceiling is the first hard limit. All four outputs mirror the same 3840x2160 60Hz signal, so total throughput cannot exceed the HDMI 2.0b spec of 18.2Gbps and TMDS clock of 600MHz.
