Please help, I recently purchased the cheapest 4k portable screen with national subsidy, but the mac mini 4 does not support a type c external monitor + power supply (another external cable is needed for power supply). Similarly, the m1macbook and m1 mac mini are both normal, (cable A Thunderbolt 4 miscellaneous cable, and a Thunderbolt 5 sticker cable from a sugar factory), use the power supply test (both are probably around 5W)
