UGREEN 3-in-1-out HDMI switch with remote

The first bandwidth on this shelf that fits its claim

18 Gbit/s. That is what 4K at 60 Hz conventionally requires, and it is the figure the three cheaper boxes here fall short of — 3.4, then 4K-at-30, then 10.2. If the requirement is a demanding 4K chain, this is where the shelf starts.

What the power supply buys

Regeneration rather than division. A passive box hands the source the job of driving the whole chain; a powered one buffers the signal. At 18 Gbit/s across three inputs, that is what makes the number credible — and it is why this box has a cable the others do not.

The honesty about what it will not do

No automatic switching. Stated by the maker, in its own note. It has to be told which input to use, from the remote or the button. Several boxes on this shelf leave that to be discovered.

The warning worth reading twice

The maker states that a computer set to sleep can cause switching problems, and advises setting it never to sleep. That is a specific, reproducible behaviour, and it is exactly the kind of note that prevents an hour spent blaming the hardware.

And what it is not

A splitter. One display at a time, stated explicitly.
