Apple upgraded the latest MacBook Pros display without telling anyone.

At least that’s what prominent display analyst Ross Young says. Young took to X on Thursday to point out that Apple has adopted a “quantum dot” display for the M4 MacBook Pro.

The hard technical details are that Apple replaced the red KSF phosphor film it had used on previous MacBook displays with quantum dot film. But Young’s post also makes it clear, in layman’s terms, what this means for you, the user.

What is a quantum dot display?

As Young put it, the quantum dot technology gives Apple the same — or perhaps even better — color effect than the old method, as well as more responsive motion performance.

Young stressed that the latest quantum dot films are not only highly efficient – ​​they are also cadmium-free. Apple had previously been wary of moving to quantum dot displays because they used cadmium, which is known to cause cancer World Health Organization.

These aren’t huge upgrades, but they’re notable enough that it’s strange that Apple chose not to promote this change at all. One way to think about it is maybe you got even more than you paid for.
