The new M4 MacBook Pros that launched last month have an unadvertised change with new quantum dot displays, according to display industry analyst Ross Young and reported by 9to5Mac. Young posted on X that Apple is adopting quantum dot displays for the first time and that it's using a version of the film that is free of cadmium,

The battery in the M4 MacBook Pro is bigger at 72.4-watt hours; the M3 MacBook Pro had a 70-watt-hour battery. The M3 model had “Up to 22 hours Apple TV app movie playback” and “Up to 15 hours wireless web” while the M4 model is stated as 24 and 16 hours respectively.

Big Apple display news, they have adopted quantum dots for the first time. The latest MacBook Pro’s (M4) use a quantum dot (QD) film rather than a red KSF phosphor film. Young says this provides the latest models with two advantages over earlier models.
