Can plug it in, but how do you change the brightness , contrast , color profile, etc. ? There probably is a nominal operate mode that will try to put something on the screen ( if all the DSC and DisplayPort aramerters are decoded ) ,but the non basic features of the system will not work. At 5at point what is the extra price point worth.
The is difference because “happens to (somewhat ) work” and has active technical support.
People will possibly buy this and claim it is Apple fault that all the features work. If not on the supported list that is a short support session . Same for the ambulance chasing lawyers claiming some claims. Never was supported.
