Works great! Only one issue with my laptop.
This adapter works great with my Yoga 910. Smooth video on my 4K TV. The only problem is that the audio signal is not available on my Lenovo laptop USB C port, so sound is not transmitted through the HDMI adapter. I don't know how well this adapter will work with laptops that may have sound at their usb port (if they exist.) There are workarounds. Of course there are many ways now to mirror you laptop screen. This adapter gives me a great 4k experience on my TV, and I connect sound using my laptop blue-tooth connection through my yamaha sound system. Sound syncs perfectly with the video! I highly recommend this adapter if you want to connect to a hdmi tv as long as you have another way to connect to sound if you have a usb connector no sound issue. If all you intend to do is use the adapter for presentations perhaps through a projector, then this is a excellent way to do so.

Lenovo USB C to HDMI 2.0b Adapter
Excellent device and great value purchase. Complements bridging the gap between newer equipment not having HDMI and older HDMI equipment. I consider this an essential buy for anyone wanting to bridge technology gaps. Works well right out of the box. Would purchase again.

Needs DP 1.4 capable chipset to get HDR out
Allows me to hook up my Thinkpad P50 to my Samsung 7 series and get 4K60p 4:4:4 out. This was important because the laptop only has DP 1.2 and HDMI 1.4, the former having the bandwidth for 4K60p but only could be actively adapted (meaning expensive, and usually bad adapters that may or may not handle the colorspace correctly and may subsample chroma); passive adapters would only link at 1.4 bandwidth, and 1.4 only has enough bandwidth for 4K30.Unfortunately, seems I can't leverage HDR on my device, which wasn't really a hard requirement for me. The USB-C alt mode is leveraging DP under the hood, which on this laptop is spec'd 1.2. Ergo, no HDR support, and it appears according to Nvidia documentation that HDR was never supported. Seems I can't get 10 bit color out of the quadro either, which is a bummer.

True to what it says

HDMI 2.0b: Outputs 4k HDR at 4:4:4 chroma subsampling
It's hard to find a proper USB-C to HDMI 2.0b adapter nowadays, most of the popular cables promise HDR, but turns out to be HDMI 2.0 (without the a or b, which is required for HDR). This cable presents the DisplayPort alt mode over USB-C or ThunderBolt as a HDMI 2.0b output which supports HDR10 and Dolby Vision. This worked perfectly on my iPad Pro 2018 and Dell Latitude 7480 with Thunderbolt to output 4k HDR video.(Note that your USB-C alt mode output has to be at least DisplayPort 1.4 for HDR to work. For most Intel Thunderbolt controllers, it has to be a Titan Ridge controller or newer, for older Alpine Ridge/Kaby Lake controller or others, it needs to have a Thunderbolt added or have an LSPCon chip to convert the signal to DP 1.4).

This works the way it should...
...and an OEM device that's only $18? It's just a piece of plastic, but it doesn't feel cheap. Nice job, Lenovo.It does what it's supposed to do straight out of the box... BUT if you have an Ideapad 330S, then you won't be able to drive a total of three monitors, so you might as well just use the built-in HDMI port (for a total of two monitors), and you don't need this adapter at all.

It does not work properly with HP Spectre x360
HDR and display signal are good. I got 60 Hz 2160p HDR signal as advertised. But it does not output audio for HP Spectre x360. Then I tried my roommate's macbook. The adapter works fine, and outputs audio.Spectre x360 has Display 1.4 compatible USB-C ports. It should output audio signal properly. I had another adapter that does not support HDR, but it outputs audio properly.I tried to figure out what is going on and researched many other products on amazon. Some adapters would say it is not recommended to use it on HP Spectre x360 and some other models. So, I think there is some compatible issues with the standards.I bought another adapter from cable matters, it works properly. I'm going to return this one.
