OREI UHDS-104 UltraHD 4K HDMI 1x4 Splitter (HDMI 2.0, 4K@60Hz, HDCP 2.0, EDID Management)
Reviews
Product description
If you need one HDMI source to show up on multiple screens at the same time, the OREI UHDS-104 is built for that job. It’s a 1x4 HDMI splitter that mirrors a single input to four outputs simultaneously—useful when you’re doing demos, running retail displays, or keeping classrooms synced.
The catch is simple: this unit duplicates the signal, not extends it. So if your goal is to push an HDMI signal farther away from the source, you’ll want to think in terms of cable length and placement first. With that said, for same-room, multi-display setups, the UHDS-104 looks like a practical, plug-and-play way to tidy up your AV wiring.
Key features that matter for real setups
This HDMI splitter is designed around modern 4K distribution: it supports 4K Ultra HD up to 60Hz (with an 18Gbps link rate listed). Over the paper, that’s the kind of spec you look for when TVs, monitors, or projectors expect 4K@60Hz timing and you don’t want to downshift.
It also includes HDCP 2.0 support, which is often a deciding factor when you’re splitting playback that may be protected. Add EDID management to the mix, and you get a more “it should negotiate properly” approach than a basic splitter that only relies on whatever EDID response happens to come back.
Audio-wise, it lists broad format compatibility (including LPCM, Dolby-AC3, DTS 7.1, DSD, Dolby TrueHD, and DTS-HD Master Audio). That’s a strong checklist if you care about getting synchronized sound alongside the video across all connected displays.
What you’ll notice day to day (and what you won’t)
In use, the main benefit is straightforward: one HDMI input, four mirrored outputs. That means you can route a single streaming box, media player, or laptop output and keep multiple screens aligned without repeating cables or juggling sources.
A micro example: imagine a small shop with a TV near the register and another in a display area. You run one HDMI feed to the splitter, connect both TVs (and two more screens if needed), and the same image shows everywhere. No switching, no extra remotes for the displays—just consistent mirroring.
Now the limitation to keep in mind: the product description is clear that it mirrors rather than extends. So your success depends more on cable quality and distance than on the splitter “doing the hard work.” If your displays are far from the source, you may find the setup falls short of what you were hoping for.
Tech specs that help you judge compatibility

- Type: HDMI splitter (1 input to 4 outputs)
- Supported video: 4K Ultra HD up to 60Hz
- HDMI standard: HDMI 2.0
- HDCP support: HDCP 2.0
- Data rate: 18Gbps
- Audio support (formats listed): LPCM, Dolby-AC3, DTS 7.1, DSD, Dolby TrueHD, DTS-HD Master Audio
- EDID management: Included
Connections, setup, and the “don’t get surprised” details
The UHDS-104 is described as metal-built and compact, with plug & play installation and no drivers required. That matters if you just want it working quickly without digging into menus or software.
It also calls out HDMI cable length guidance: it works best with HDMI cables up to 30 ft for stable signal performance. If you regularly operate near that limit, quality of cables and how you route them (avoid sharp bends, keep them secure) becomes part of the “it works or it doesn’t” equation.
One more practical note: the included package lists a power adapter (dual voltage with US plug), an international adapter/converter, and a user guide. If you move between regions or want the flexibility for travel setups, that included hardware is a small convenience.
Pros, cons, and who it’s for
Where this splitter makes the most sense is when you want mirrored output across multiple screens in the same general environment. Think: presentations, retail and bar displays, classrooms, or home entertainment where everyone is meant to see the same feed.
It’s not the best fit if you’re trying to extend video to remote locations. Since it mirrors rather than extends, you can’t treat it like a long-distance distribution solution.
If you prioritize smooth 4K@60Hz output, HDCP 2.0 compatibility, and a wider audio format list, the UHDS-104 matches that direction pretty well. It’s also the kind of unit that tends to sit in the “reliable multi-display utility” tier rather than being something you’d use for high-end AV signal processing.
Is it worth it?
Buy the OREI UHDS-104 if your plan is a 1-source-to-4-screens mirroring setup and you need 4K up to 60Hz plus HDCP 2.0 support. It’s especially worth considering if EDID management and broad audio format compatibility are important for your use case.
Skip it (or at least rethink the approach) if you’re counting on it to extend HDMI signals farther than your cabling can support. And if your displays don’t all need the same content at the same time, you may be happier with a different routing strategy than a mirrored splitter.
