HDMI to USB C Adapter Cable 3.3ft 4K60Hz, Unidirectional HDMI System to Type C Monitor, for hdmi Source (Laptop, PC, Steam Deck Dock, PS4/5, Xbox) to Display on USBC Xreal Air, Nreal, Portable Monitor

Trying to connect the HI-DEF HDMI *OUTPUT* of a 4K NVR to a spare USB C video INPUT port on my monitor. Most of these cables don't work BECAUSE THE BUYER DID NOT READ THE DESCRIPTION! This is for HDMI OUT to USB-C IN whereas the vast majority of (the much lower priced) others are for USB-C OUT of a computer to HDMI IN of a monitor (reverse of what I am doing). This does require power to the cable which is received from a USB-A male connector on the cable. I plugged the USB cable into a spare port on a powered USB hub and it worked fine. You can also use a USB Wall power block I'm sure. The adapter runs lightly warm to the touch which is not a problem.

I had to get a new laptop and when I did, my new one only had one USB-C port making it impossible for me to use both of my MaxFree screen extensions. This cord worked perfectly and I now have 4 working screens again! The extensions require a USB-C while I had to use the USB-A and HDMI in the laptop. The only thing I don't love about it is how far out the HDMI sticks out from the computer, but that's such a minor issue.

Who knew that different C cables actually work differently….not me! I purchased a dual screen off FB marketplace, it came with 1 cable but when I got it home it didn’t work. Chopped it up as a loss and ordered a $120 new one. When it came, it came with multiple cables, thought hmmm let me try these cables with my used screen, it worked! Ordered cables from Amazon, sent the $120 screen back. Originally ordered some cheapies….long story short the cheapies didn’t work, turns out there are different types…..these work!!! :)

Did you know that pretty much all HDMI<->HDMI cables are bidirectional (ie; doesn't matter which side you plug into the source vs. destination), but nearly all HDMI<->USB-C cables are unidirectional (ie; one end is for the source of the video, while the other is for the destination/display)? It turns out that USB-C to HDMI are common, but HDMI to USB-C is not. That is because most monitors have HDMI as an input, not USB-C, so the cables are meant to have the USB-C end plugged in the PC (source) and the HDMI end plugged into the monitor (Destination/Display). Portable monitors, on the other hand, often just have USB-C ports for power and input, and no HDMI ports. In my case, my laptop only has one USB-C thunderbolt port, which I need for a hub to plug all of my other periferal devices in (thumb drive, ring light, webcam, external speaker, etc.). Therefore, I could only use the HDMI port on either my hub or my laptop to attach my portable monitor. This requires either a bidirectional HDMI<->UCB-C cable, or a unidirectional "HDMI to USB-C", which is the opposite of most cables on the marketplace. I chose this cable because it CLEARLY states that it is unidirectional "HDMI to USB-C", and it even has a picture of the usage (HDMI end plugs into PC, and USB-C end plugs into the monitor). The video travels FROM the PC (HDMI) *TO* the monitor (USB-C). It also states that it must be a direct connection (ie. not through a hub), so it didn't surprise me when plugging the HDMI end into my hub didn't work (no ding for that). However, even when I plug the HDMI end directly to the PC, it DOES NOT WORK (see pic). This cable is clearly a dud. Sigh...

Went back and forth based on reviews - made the determination a lot of people simply don’t read and purchased this for a use case that doesn’t work - I have a portable monitor that connects via usb-c - I wanted to connect my Xbox and or ps5 to it - both work without any issues - if your looking to do something like this, it works fine

Purchase to add a second monitor to my laptop. It didn't work at the time I tried it. It my have been operator error. Will re-test again

Works

I bought this to work with my portable monitor. For those that said it didn't work. I can see it in another reviews picture what they didn't do. You have to plug the USB C into the portable monitor, you have to plug the HDMI into the laptop, you also have to plug in the USB A into the computer as well. Once I had all three plugged in worked like a charm and it works great. My laptop is older and does not have a USB C plug in so this worked perfectly.

I have checked with xreal air 2 pro and pc and its working fine for pc user i have initially have issue with pc but after changing usb power to red usb port then it worked. I have tested with pc, ps5 and xreal air 2 pro also no issue with audio in xreal air 2.

Très bon produit

Werkt perfect met mijn xreal one pro

lo utilizo con mis gafa's VITURE Pro y de mi experiencia funciona como debería.

It is perfect for connecting AR Glasses to PS5 also many Tvs.
