Lowest latency wireless display output to TV from MacBook Pro M5 as a desktop space?

Good afternoon folks!

So I love experience of an iPad Pro M5 connected to the MacBook Pro M5 as a 2nd display using sidecar. Latency is fantastic.

Wouldn't it be awesome to have this same thing on a large TV. So would iPad connected to the TV using HDMI for extreme low latency huge work while using Sidecar?

Of course there are high end 4k HDMI transmitters I can plug into the MBP M5, but then you dealing with a giant device hanging off and kills portability.

I've tried Airplay 2 to the Apple TV 4k and it's kind slow and also I can't get the extended display to show up as a Space. (Apple didn't seem to ever implement this)

Open to all solutions. Just want closest to native feel. Our glorious AI's say Sidecar and HDMI output from the iPad Pro M5 to the TV *simultaneously*, is not possible.. but you know it's an LLM so there's that...

Had another idea if Sidecar and iPad HDMI output cant be used simultaneously. Instead use Luna (https://astropad.com/product/lunadisplay/) to the iPad, and then use HDMI to the TV.

I'm gonna try this out and report back. This should give the *ultimate* "Big TV as a native wired monitor" feel over wireless. Which will be awesome if it works!

Yes one could also go wired, but it's my laptop in the living room and its nice not dealing with cords (my partner not a fan too), and also freedom to switch from sofa or work at living table etc (which is kind of the point of a portable device)

Should be able to get latency < 25ms on 5ghz WiFi too.
