Really? I just recently tried out (and took a photo of) an m2 macbook pro with 2k displays attached, lid open and screen mirroring on. 4 screens with 60“ tv in the distance. Would that really not work on an m3 mac?
I can do 4 monitors with my lid closed with my Dell XPS 13. It is crazy to see an Apple Laptop that costs $2000+ cannot do a laptop that costs $1000. People with money really don't know how to shop.
