The only question I have seems to be the most elusive one of all from what it appears...and that is simply whether or not the M2 Mac mini is going to finally support dual 4k Thunderbolt 3/4 display output?
The fact that the M1 Mac mini doesn't is such a massive disappointment and missed opportunity considering that M1 MacBooks do and so too does the Intel version. I picked up 2 LG Ultrafine 4k 23.7 inch monitors recently, not really thinking or realising that the M1 Mac mini couldn't do this. They both operate via thunderbolt and whilst they look amazing and work brilliantly with my Mac mini, in order to connect the 2nd monitor I have to cheat by using a HDMI to DP adapter connected to a DP to Thunderbolt bidirectional cable and unfortunately this isn't the cleanest of methods and possesses a few inconveniences such as an occasional flicker, not being able to use the USB-C sockets for down streaming and not being able to control brightness etc (as there as no buttons on the monitor itself).
I am however keen to put up with this in the hopes the M2 Mac mini will allow dual display and/or daisychaining and then I can simply sell and upgrade my M1 Mac mini.
Fingers crossed eh!
