A:AnswerI asked HP about this. There is not. There is a height-adjustable stand apparently for a similar model that mounts the same way, but it can't be ordered on its own. And no VESA adapter.
A:AnswerIt's compatible with MacBook Air. I'm using it with a M2 based Air.
It's not wireless. It's either HDMI or VGA. I used HDMI cable it comes with to attach it to MacBook Air with additional cable which goes from Thunderbolt to HDMI. There are a number of choices for that cable.
