Screen Mirroring iPad mini 16.2 update

UxPlay is a Linux multi media app – a mirroring server – that utilizes the screen mirroring ability of my iPad mini, now perfected in iPadOS 16.2. I launch it on my external monitor, then when the iPad sees it launched I touch the icon and the iPad is sending audio and video to my big monitor. I just now watched Youtube with it with no lag. So, I think I will be all set to use it for my upcoming Zoom meetings. I hope this answers your question.
