Ask HN: Ever used non-AVP glasses as a virtual display? Which ones?

Recent Ask HNs seeking Apple Vision Pro users (https://news.ycombinator.com/item?id=48465702, (https://news.ycombinator.com/item?id=48275508) suggests a few folks use non-AVP glasses as a second screen. There are so many products in the space. Some say theirs are great, others say steer clear. But as it’s offtopic for an AVP post, discussions tend to peter out.

Lots of us would love a giant floating screen to code and work on - or even multiple surrounding us. But many are not interested in AVP.

HN community: if you use or used glasses as a virtual display, which one, what have you tried them for, what are they good for / bad for, how up to date is your info, and what else do we need to know?
