You can stretch a window across multiple monitors if you uncheck “displays have separate spaces” in mission control settings. It fixes most of the problems in this post. I run five monitors at 4k 60Hz every day with my max spec mbp. Four are portrait and two are landscape. (One portrait is DisplayLink usb) I actually have six monitors. One is split with an active HDMI splitter. I definitely have trouble sometimes but the M1 is actually a lot better than the intel mbp because changes to settings are near instant. Most of the time it just works. Tricks I’ve learned: 1. Always plug the monitors in the same ports. 2. Lock the screen, then unplug monitors to keep your windows arranged. 3. I use SwitchResX to save and restore my monitor positions. Its not 100% reliable but it gets things mostly arranged and a few rotation tweaks in settings gets everything fixed. 4. It helps to have monitors of distinct models. When I have multiple of the same model and those are the ones that have problems getting rotation swapped.
