HDMI Male to USB-C Female Cable Adapter with USB C Power Cable,Uni-Directional HDMI (source) to Type C 3.1 (display) Converter,4K 60Hz Thunderbolt 3 Adapter for MacBook Pro,Microsoft Surface,Xreal Air

Incase anyone has a dock and wants to run a steam deck with a portable Monitor that only has one usb c… yes it works.

Works with limitations - no 4k, no audio, no USB hub - only 720P video (if you're okay with that). Connect HDMI in to PS4 and use a standard USB-C data Cable (NOT THUNDERBOLT) and you will get 720P video support on the LG Ultrafine monitor (plug the USB-C into to the "Thunderbolt" input on the Ultrafine). Use Bluetooth audio or connect wired headphones to the controller for audio. Great for a desk setup and if you're not the type to count pixels like me. Hope this helps!

This product is a piece of junk if you want to connect your portable monitor (Asus MB16AC in my case) to your PC as a secondary/tertiary monitor. When you use the computer it works just fine, but if you put the computer to sleep, the adapter doesn't know what to do and will disconnect a bunch, causing your windows to move around. This behavior also happens if you have windows put your monitors to sleep after some time. This also happens when the PC is shut down. The adapter just doesn't know what to do when it isn't getting a signal, so it keeps restarting, causing my monitor to flicker and constantly power up and down.I also encountered an issue where if I wanted to run my monitor at 100% brightness, I needed to put a lot of pressure onto the USB power cable because it must be loose inside the adapter housing or something. If I let go, constant restarting of the monitor, probably because the USB cable isn't making good contact without that pressure on it, so it can't supply enough power. This happened with multiple different cables, not just the one that came with it, so it's probably something defective inside the adapter (and looking at other reviews, it seems to be widespread).I'm sure that for some people this product works fine, but for PC users or even Mac users, it will not function like a normal monitor would. At this point I'm better off getting a portable monitor with HDMI input, as I can't find any other product like this that can simultaneously power the monitor and convert an HDMI signal to a DP Type-C signal over one cable (to the monitor). I really wish this was better, but it's practically useless for me.

HDMI cable connector worked great with no connector issues

I have this set up with a Skull & Co Jumpgate dock and powered by a Ravpower 20kmah pd power bank. Powerbank is plugged into the switch dock, hdmi adapter is plugged into the switch dock for video and the micro usb cable for power for the hdmi adapter. I plug in the USB C from the dock to the Switch or my Note 20 Ultra and it works for video. I am running on Nreal air 07.1.01.192 firmware.A Redditor also posted this works with the Steam Deck so whoever said it doesn't is likely mistaken.*Note* audio is not passing through HDMI, but I haven't done any troubleshooting yet. I use bluetooth headphones anyway, so I haven't felt a need to spend time on it.I set this up because I wanted to be able to use the switch and nreal, but also use my phone and nreal and charge my phone at the same time. The other alternatives are $150 thunderbolt 4 hubs which are way bigger and take special cables to power. This $30 adapter plus a $40 Switch dock do the same job for less with less bulk. I have an old soundblaster USB audio adapter which works to provide a wired headphone option.

This solved a big headache for me.I can't believe Apple doesn't make this more obvious to idiots like me who just assumes everything that they sell works together. Mac Mini M1 only give one thunderbolt monitor output and 1 HDMI output. It will not run two LG UltraFine 24md4kl without this adapter (be sure to use USB-C cable not the Thunderbolt Cable)You loose some functionality on the Ultrafine running off the HDMI monitor. You'll need an app like Lunar to control the brightness from the keyboard (works great!). Also the USB ports won't work. You'll need to reset the computer to the ability to "scale" "larger text....more space" in Settings > Display.Seems a step back for Mac Mini's to be honest, but at least this device gives a workaround since I have people waiting to use these computers.

I fussed around with this thing for over an hour and couldn’t get it to work with my portable monitor. I finally saw that you needed a special USB-C cable. I figured those were all the same, but when I found one that came with my external monitor, it worked.

When I first plugged it into my XSX it worked perfectly albeit with the sound issues some people have complained about. The next time I tried it with my computer to no avail, which left me scrambling to test my monitor with other usb c devices which also didn't work. I tested different methods and here is what I found in order to get it to consistently work.1.Make sure you have at least 1-2 Usb C cables to test with (High speed cables that are thicker) and you should test these cables with a usb c device to make sure they transmit video.2.Plug the hdmi part into your console, pc, or other hdmi output device first.3.Next plug in the 5v power supply to the dongle. For me it consistently worked when usb power is plugged into a standalone power cube (if possible) but you can try plugging it into your device as well.4. Wait about 30-45 seconds for the microcontroller in the dongle to boot up and prepare for connection.5.Finally plug in your USB C cable that is connected to your monitor and viola it works 4k @ 60hz.If you follow these steps correctly then it should work for you as well.Other notes:I don't have any issues with my monitor sleeping and staying connected when woken up.I do however have to redo the entire process to connect if: A or B happensA: Monitor is completely powered off. Unplug usb c and power cable and restart steps to connect again.B: USB C unplugged from either side. Then the process must be restarted.
