Lenovo USB C to HDMI 2.0b Adapter

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.

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.

I have to note for the record that I bought a "used" product. Although, this adapter had never been opened and for the inexpensive price, I was willing to risk it. I thought I was going to have some compatibility issues as I was connecting to a very old Dell monitor (before the wide landscape monitors were a fad) so I had my doubts, but it works perfectly. I have it set up from the monitor with a short DVI-D to HDMI adapter, an HDMI cord, and then the HDMI cord to this HDMI to USB-C adapter to my Lenovo Yoga. Perfect, no issues whatsoever. Hope this helps!

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).

Works exactly as we needed it to.

For monitors that don't have USB-C. After having issues with my HDMI ports, older dongles, and 4k monitors and refresh rates, I decided to try this dongle because it is HDMI 2.0. I can confirm that a MacBook Pro and a Lenovo Ideapad 5 both can send 4k at 60 Hz with dongle. Works great, feels very high quality and it's plug and play.

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.

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.

Perfect, very happy with the item.

Salut, j'ai acheté cet adaptateur afin de connecter un second écran externe à mon pc via le port usb c. Je ne sais pas pour quelles raisons, mon appareil ne reconnait pas du tout l'adaptateur. Malgré mon travail d'informaticien, le problème ne peut pas être résolu. Un conseil, commandez-en un autre que celui-ci!

My work laptop only has one HDMI port which was not allowing me to add a secondary monitor. With this adapter I am able to use the USB Type C port and convert it to another HDMI port. It does exactly what I wanted it to do.

I have used other models in the past but they break from constant insertion and removal, especially if done many times throughout the day. This model is enough to handle that punishment and is secure when inserted.

I bought this to connect my Lenovo thinkpad to 2 monitors. It works. Now I have 3 screens.
