If you are using NReal Air (or I supposed their rebranded ZReal Air 2 AR glasses) with the Steam Deck you are not only living the future, but you probably want this adapter. It is the required piece in order to include a docked setup or a charging option during use.

Plug the Steam Deck into the Hub as normal, connect the mouse and keyboard to the hub through the USB ports, then plug in the AR glasses, such as the Xreal, into the HDMI port on the hub through this device. Works perfectly! You cannot use one of those charge and play splitters as the power side does not transfer data and acts as a block between the hub and the Steam Deck communicating.

It send a 1080p image to my Xreal 2 Air Pro glasses, but no sound. I still have to connect headphones to my Xbox controller to get sound.

Suppose your USB-C port on your laptop doesn't support external video (DP Alternate Mode), and you have an HDMI port available. In that case, this is what you need to connect to an external USB-C monitor that has no other video connection available. This is a rare item, and I looked extensively for it. Still, it is typical of SIIG to develop the right video converter adapter when nobody else has bothered to do it. This is a one-way connection from the laptop HDMI port to the USB-C external monitor port. It does NOT work the other way around. It was a tad pricey, but it did the job.

Not working with Mac Mini M1

Bought this for use with a pair of xReal air AR glasses. It works perfectly! It has audio and data pass through, as well as video of course. Allows me to use my computer without USB-C alternate mode to drive the glasses. The size isn't terrible, it's smaller than some of the USB hubs I have, so bringing this along with my laptop hasn't been an issue either.

USB-A port does power the external monitor. I was about to return because it kept flashing. I decided to just hold down the brightness on my external monitor until it finally worked. You can only use your external monitor at about 25% brightness. I don't like this, but it literally is the only option I have found to work on my USB-C monitor. I use this one because it's mobile.

So…. Here’s my longterm use of this adapter. I have a Thunderbolt Display and needed to connect to my work laptop that only has an hdmi port. When it works it works, but you have to plug and unplug several times because the display begins to flicker. Once you play the hot and cold game it works but is annoying. There aren’t many other adapter that can provide this solution so you may have to deal. However I did find another adapter and seems to working as expected. If your monitor starts flickering that will be part of the user experience
