mirror mac desktop to iphone

Hi all, this is more a mac question but figure I'd try the brains trust here regardless

I need to mirror my Mac desktop to my iPhone. The problem I'm having with all the usual solutions is that there's a lag because they transmit wirelessly. For what I'm doing I need imperceptibly low latency. The ideal would be the reverse of what you can do by connecting an iphone to your mac via lightning cable but apple doesnt allow that!

Does anyone have any hacks or gadgets i can try please?

Thank you

A VNC app? I don't know what the latency would be, but if both are on the same local network it might not be terrible.

I use Duet over a wired connection. Works absolutely perfectly!

Thank you!!
