The Xreal Air augmented reality glasses have been superb since the day I got them. I continue to use them in unexpected ways because they are quick and simple to connect to almost anything. To their credit, the company has remained steadfastly committed to the success of the product. Even suffering a re-name didn’t slow them down.

Recently, Xreal released the beta edition of their Nebula app for Windows. The update lets Windows users experience two-wide, three-wide, and ultrawide monitor setups without any actual screens. They’ve also released several VR apps in their Nebula store. The last firmware update added the ability to consume traditional side-by-side 3-D video.

The newest firmware release adds support for video refresh rates up to 120 hertz. The update is simple to acquire, just upgrade your Android or Mac Nebula app to the latest edition and connect the glasses, accept the update when prompted.

If you don’t use the Nebula app, connect your glasses to a computer with the Edge or Chrome web browser installed. Then visit this page: https://ota.xreal.com/en/air-update.html and follow the instructions to download and install the new firmware. There are reports on Reddit that the web page (over the air) upgrade isn’t functioning properly.

Once you have completed the firmware update, press and hold the brightness + button until you hear two beeps. The first beep is side-by-side 3D mode, the second is 120 hertz. The glasses remain in 120hz mode until you disconnect them. At the moment, the faster refresh rate has to be engaged in this manner every time.
