    Works well enough to extend either my MacBook Pro or my USB-C-only Asus Chromebook to an external monitor which, in my case, is a Sony Playstation 3D monitor...I just think it's a bit overpriced at 30 dollars though...one coulda just both a straight up USB-C/HDMI combo cable that starts at 15-20 bucks.

    Pretty simple and easy to use, I wanted to run two different screens off of my laptop (three including my laptop) but it only has one HDMI port but had a USB-C port so I bought this, now I have three different screens and it makes multitasking much easier.

    I had a multiple port usb hub prior to this one. It started giving me problems so I decided to just get a single usbc to hdmi adapter. Has been working great.

    Rather than buying a docking station to get a second HDMI port for my work laptop at home I got this. Connected to Thunderbolt port, and it worked. No Drivers or settings just plug and play. Not sure if it works with a USB only port. Used almost every day for 3 months thus far.

    It works. It’s a much cheaper option, than most of the going devices out there, for $50-150. Pretty solid, so far: running a Lenovo Yoga to a Vizio 24” smart TV. Best luck.

    If you want to use this from your cell phone it will use up too much battery. I upgraded to a different unit that charges the battery on my phone at the same time. It still doesn't keep up but I can watch 4 hours of ultra HD on my 40 inch. Best to upgrade.

      Jeffster423, I'm sorry to hear about the battery not lasting. We offer the JCA379 which has an HDMI port, USB-C for charging, this way your battery will not drain while playing videos and a USB 3.0 port for a peripheral. If interested in learning more about it, please don't hesitate to reach out to us and a rep will gladly help.

    Will do 4K, not HDR

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I learned a little more about different HDMI and Display Port standards after I purchased this and subsequently returned it. I needed this to use the USB-C/Virtual Link port on my new video card. For the most part, standard 4K video worked. However, when I enabled Dolby Atmos audio and HDR it is not supportable. This is because it is only a Display Port 1.2 and those features are more for DP version 1.4. I attempted this with my Oculus Rift as well and continued to get flickering, which is not good for VR. If you are simply trying to output video and audio from USB-C device to a display up to 4K, this works fine. If you are looking for something to push current technical high end capabilities, this will not work.

    I needed a USB-C to HDMI adapter for hooking up a new gaming system to my HDTV and I picked this one up. I've never heard of the company 'j5create' but I've been happy with this buy. The cord is not very long but it also not thin or flimsy. I have the adapter hooked into a HDMI cable it doesn't really need to long for what I use it for.

    I scream a lot of my shows and movies from my phone. However, I don't have a smart TV or WiFi to mirror my screen. This converter allowed me to hook up my Note 9 to my TV and watch all of my content seamlessly!!!! Easy to use and great picture!!! Love it!!!!
