LUOM OZF8K1 1x2 HDMI 2.1 Splitter

This LUOM OZF8K1 splitter duplicates a single HDMI 2.1 source across two displays simultaneously. It handles resolutions up to 8K at 60 Hz and 4K at 120 Hz with full 48 Gbps bandwidth. The unit supports HDCP 2.3 and earlier versions down to 1.1. A DC 5 V power adapter is included in the package.

Ideal for mirroring consoles

Gamers connecting a PS5 or Xbox Series X to two 4K 120 Hz displays will benefit from VRR and ALLM pass-through. Home-theatre users sending 8K 60 Hz or Dolby Vision content to a projector and a TV simultaneously are also well served. Buyers needing independent extended desktops or separate content on each output should look elsewhere, as this device only mirrors the input signal.

HDMI 2.1 48 Gbps bandwidth with 8K 60 Hz support

The single-link maximum of 8K at 60 Hz and 4K at 120 Hz over HDMI 2.1 determines whether your source and displays can run at their native capabilities. EDID management and a built-in down-scaler allow mixed-resolution sinks to stay in sync. Verify that both target devices accept the same mirrored resolution and refresh rate before purchasing.

Questions about this item

How do I install the LUOM OZF8K1 splitter and what step do people often miss?

Connect the included DC5V power adapter first, then link one HDMI source to the input and two displays to the outputs. The step most people miss is powering the unit before connecting video cables, which prevents signal handshake failures.

What maintenance or replacement will the LUOM OZF8K1 need over time?

The external DC5V power adapter is the only part likely to need replacement after extended use. The splitter itself has no moving parts or user-serviceable components, so no routine maintenance is required beyond keeping vents clear.

What limit appears first when the LUOM OZF8K1 runs continuously at 8K 60Hz?

The 48 Gbps bandwidth ceiling is the first hard limit. At 8K 60Hz the splitter passes the full 48 Gbps stream, so any cable or display that cannot sustain that rate will cause drop-outs before the chip overheats or throttles.
