NEWCARE HDMI Splitter 1 in 4 out (4-port) for Mirror Only: 3D and 4K 30Hz support
Product description
What it is and what it’s for
A 1 in 4 out HDMI splitter is meant for one job: take a single HDMI source and show the same audio/video on four displays at the same time. This NEWCARE 4-port HDMI splitter is built around that “mirror only” idea, so it’s useful when you want the same movie, game, or streaming feed on multiple screens without the hassle of switching cables around.
So, if you’re setting up a small home entertainment zone, a family viewing arrangement, a shop-style display, or even a shared gaming moment, this is the kind of accessory that can save time. It’s also positioned as fairly straightforward gear: plug in, power it, and it should pass the signal through to the four outputs.
Key features that matter in day-to-day use
On paper, the headline is simple: one HDMI input, four HDMI outputs, with the splitter copying both audio and video to all connected screens at the same time. That mirror-only approach is exactly where this model makes sense, because you’re not trying to juggle different content per TV.
It’s also listed as supporting common formats such as 3D and up to 4K x 2K at 30Hz, alongside Full HD options like 1080P. Whether it delivers the smoothness you expect will still depend on your specific source and content type, but the spec set suggests it’s targeting typical living-room viewing and consoles/streaming boxes rather than high-end pro workflows.
One more practical detail: it’s small and mini-sized, and it includes a USB cable for power. That makes it easier to tuck away behind a TV or bundle with your other HDMI gear when you travel.
What you’ll notice when setting it up
Installation here is largely “plug and play”, but there are two gotchas worth flagging early. First, you must connect the HDMI source to the input side of the splitter—if the HDMI connections are reversed, it won’t work. Second, it needs USB power, and the included USB cable is intended to be used with a USB power adapter (the adapter itself is not included).
In a real-world micro scenario: imagine a Fire Stick in your lounge with four TVs/monitors in different corners. You connect the Fire Stick to the splitter input, run HDMI leads from each output to the screens, power the splitter via USB, and then everything “mirrors” together. The moment you pause or change apps on the Fire Stick, the other screens should follow.
Limitations to consider before you buy
This is the part people often miss with splitters, so it’s worth being blunt: it does not support expansion mode. That means it can’t display different content on each display.
There’s also a resolution-sharing limitation noted by the seller: this multi-display splitter does not support mixing different resolutions. If the connected screens have different resolutions, the lower resolution will be what you effectively end up with on the whole setup. In a mixed-setup home (say one older Full HD TV and one higher-spec display), you may have to accept that downgrade.
Finally, it’s not clear from the information provided how it behaves with every possible HDMI source type at the margins (for example, edge cases around refresh rate negotiation). If you’re running something more demanding than typical streaming, consoles, or DVD/Blu-ray players, you may want to sanity-check compatibility expectations.

Who it suits (and who should skip it)
It’s a solid fit if you want the same picture and sound on four screens from one source, and you’re happy with mirror-only operation. It suits situations where simplicity matters—multi-screen family viewing, quick demo setups, or a shared games night—especially when most displays are broadly in the same resolution range.
It may not be the best choice if you’re trying to run different content across four displays at once, or if your screens are mismatched in ways that will force a resolution downshift. If your priority is multi-tasking different outputs (not mirroring), you’ll likely be disappointed by this model’s limitations.

Final verdict
Is it worth it?
Worth buying if your plan is straightforward: one HDMI source (like a streaming box, Blu-ray/DVD player, or console) to four screens, all showing the same content, with 3D and up to 4K at 30Hz as part of the expected experience. The USB-powered, mini design also makes it easy to live with.
You might want to skip it if you need independent screens showing different content, or if you routinely mix very different display resolutions and can’t afford the lower-resolution outcome for the whole chain. In those cases, the mirror-only approach and shared-resolution behaviour become the limiting factors.
Mini FAQ
Will it work with consoles and streaming boxes?
The listing suggests it’s suitable for standard HDMI devices such as PC, PS/S4 Pro, Fire Stick, Blu-ray/DVD players, Roku, and similar sources.
Can it extend the signal to different content on each screen?
No. It’s described as mirror only and does not support expansion mode.
What power does it need?
It uses USB power, and the USB cable is included, but a power adapter is not included.
What happens if my TVs have different resolutions?
The listing says it doesn’t support mixing different resolutions, so the lower resolution will be displayed across the outputs.
