Review on 🔌 Amiroko USB-C to Mini DisplayPort Adapter: 4K Support for MacBook Pro, Alienware, Dell Monitor - Gray by Jason Ortiz

I don't have this adapter that works with two computers running Big Sur. Big Sur bug I know the monitor and display adapter are working fine because I've been using them for years with my iMac (27" Mid 2011) with version 10.13.6 installed. MONITOR: Cinema Display (30" DVI Late 2005) (M9179LL/A) See photo for an example of an unusable video display. Also tried on MacBook Pro 13" 2017 Four Thunderbolt 3 Ports. Same result. Sometimes Cinema Display gets overlooked. Sometimes the power light would come on and then turn off (and turn on) again. CABLES: + MDP and USB display cables connected to a dual-link DVI adapter. + DVI adapter MDP cable connected to the Amiroko adapter (this product) which was connected to the iMac USB. C+ port DVI adapter USB cable connected to:++ (iMac) USB Type A port++ (iMac) USB Type A port on an external USB hub (connected to iMac Type A port ) USB-C adapter to USB-C++ port (MacBook Pro) than above because it doesn't have Type-A ports
