I appreciate its a marketing video, but this is just a lie, no? What is the actual supported input resolution of the display? How do virtual monitors work - are they just a composite screen that needs to fit in that max input resolution, or is there some virtual viewport that is being managed by the connected device? There is so little information about these on the website, and the few reviews I can find are basically people who got them for free (youtube is seemingly full of these right now) and clearly don't use multi-monitor setups to any great extent.

You can check discord for a lot of people trying these out in various ways. The screen gets anchored to a direction and distance from you, so yes, leaning in would push the screen back (which feels natural, especially when you walk around).

  in those videos i linked, the user is leaning in and the screen stays in the SAME position, which is why I am asking how it can be an accurate representation

They do have accelerometers as well as gyroscopes, so technically they could integrate acceleration twice to keep track of position...but in practice it's way more reliable to just keep it at a constant distance from the head.

  sure, but in the videos its NOT a constant distance from the head, hence the question
