A nicely made USB-C to HDMI connector. The device is has a metal shell and while the short cable isn’t braided, it feels solidly made. It obviously works well as something to travel with.
It works well with both the iPad Air and MacBook Air that I tested it with.
Note that the housing does get a little warm while in use, but nothing worrying, and in line with other HDMI connectors I’ve used.
MT-VIKI USB C to HDMI Adapter
Simple plug and play adapter, with HDMI female end. has a very short 15cm plastic coated lead which keeps your desk/lounge tidy for occasional use. For a permanent connection I would look for an alternative longer lead with HDMI male end.
Arrives in zip-lock bag – doesn’t have plastic connector on USB-C end.
I was forced to buy a few different brands one after another, because they all seem to make claims that are not entirely true.
In this adapter’s case, it can achieve HDMI 2.1 spec resolutions, uncompressed RGB included…
However, when attempting 4K 120Hz HDR @ 10bit RGB with LPCM audio, the adapter works from cold perfectly for about a couple of minutes, but when it heats up, that is when it will start dropping audio intermittently. When you turn off HDR and don to 8-bit then the audio doesn’t drop. So it seems the circuitry inside is running at its limits and the heat causes issues. Now this could just be the unit I had, so don’t completely discount this one as it is one of the rare few that is HDMI 2.1 compliant, but if above problem happens to you too then it may very well be a design flaw of the adapter.
Those who are after a Thunderbolt 3/USB4 compatible 8K adapter, to help you avoid having to make returns (I’m doing you a favour here by saving you on headaches), in the end the one that worked without issue for me was https://www.amazon.co.uk/dp/B0B57T77H3
