Hello everyone, I see that the M1Pro chip is able to support 2x 6K XDR displays. However I was wondering how many 4K monitors could the M1Pro chip display to? Looking to try and save money to get the M1Pro chip instead of the M1Max if it can support 3x 4K displays.
Each display requires substantilal memory bandwidth AND a Hardware rasterizer/Display-generator.
There is One available (plus built-in) on the M1, two available rasterizer/Display Generators on the M1 Pro, and four available on the M1 Max.
Closed-Display Mode:
To re-use the one for the Built-in display takes additional very high speed multiplexing Hardware and generates a lot of Heat, and Apple has decided NOT to design it that way. The general article supporting closed-display mode has been removed from the article Library, which I see as an additional indication that the feature is not going to be available.
But but but...
the built in display (for which you paid dearly) is now approaching a 4K display all on its own. Leave the built-in display open and use it as one of your displays.
