Viture One

A wearable 1080P display with built in speakers, in the form of a large pair of eyeglasses. It works so well, I gave away my portable monitor.

I use it with my laptop and my smartphone.

Advantages

Improves posture since one does not have to look down at screen anymore

Have a 3D mode for 3D videos, so that two different video frames can play to each eye. Works well, but unfortunately it's very difficult to find 1080P 3D content

Downers

A bit fuzzy toward the edges

When using with phone, any limitations of Samsung DeX still apply, plus:

Is only 60Hz
