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 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.

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...

Great 👍

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 as intended, I use it to play keyboard and mouse on my Steam Deck through the Dock to a Portable monitor as a Bigger screen. One thing i will say is that the USB A MUST be connected to a 5V power source as HDMI does not provide power to a Display.

100/100

TLDR: The cable no longer works after 8 months of regular use, DOES NOT utilize the HDMI port input for portable monitors, and would often disconnect if I plugged any other usb device into my laptop. I purchased this cable to use for my laptop when I'm on the go and need my portable monitor. My portable monitor had some picture quality issues when using the usb c and when I saw this cable would utilize the hdmi port for video input I got it immediately. Received it in June, it worked great however when I plugged it in I noticed that it wasn't utilizing the HDMI port at all (my pc still recognized it as a generic usb device and not as an HDMI input device). I didn't mind because the picture was better so I used it. Well after only having the cable for 8 months, this morning when I plugged it in absolutely nothing worked. To trouble shoot I used the original cable my portable monitor came with and it worked fine. Personally I would avoid this if you truly want the HDMI quality.

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.

Werkt perfect met mijn xreal one pro

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

Funguje, jak má, tedy umožňuje připojit USB-C monitor k počítači, který má jen HDMI a nemá USB-C s grafickým výstupem. Funguje spolehlivě. USB-A kabel pro napájení by mohl být delší, protože některé monitory mají velkou spotřebu, tak je výhodnější je nenapájet z USB-A notebooku, ale adaptérem přímo z veřejné sítě.

產品讓我得到了非常好的體驗。
