The maximum brightness output for the new Macs is 1000 nits sustained and 1600 peak. The caveat is that this brightness threshold is only attainable whilst viewing HDR content - That means the rest of the computer's interface is capped at the previous threshold of 500 nits from earlier-generation machines. This poses the question: How do you achieve the 1000-nit sustained brightness output capacity for SDR content on the MacBook Pro?
