Displaylink is not a hack. Its commercially supported. You buy a displaylink hub, you can pick up the phone and they will sort out your problems. The same tech is used, for years, to provide multimonitor support for laptops in corporate offices. This was always the surest way to allow all sorts of dell, lenovo and apple laptops to work with multimonitor setups. Its not without flaws, but it does work. Saying "m1 does not support more than one ext monitor" is misleading; it sure does, with the extra (and not necessairly cheap) accessory.
