Earlier quoted context omitted.
I fixed my issue as well with a dock from UGreen and the DisplayLink software. Just unfortunate I had to do it.
I tried a DisplayLink dock once with my M1 Max MBP. It was incredibly laggy, pegged my cpu at 40%, and didn't let me set the correct resolution/scaling level for either of my monitors (horizontal 4k 32" and a vertical 4k 27", nothing exotic). A TB4 dock fixes most problems, but I have to hack the EDID to disable YCbCr and force RGB, or the colors look like absolute shit. The external monitors still look significantly…
Using more than is explicitly mentioned that is supported, you mean? I mean yeah, duh.
