The new M4 MacBook Pro lineup has retained the same marketing material as the previous-generation models, where Apple says that the mini-LED technology it employs is one of the best in the industry while stamping the ‘Pro Display XDR’ name. However, in true Apple fashion, the company did not mention that the latest portable Macs utilize Quantum Dot technology, leaving others to discover this hidden internal specification. One display analyst has stated that this change delivers equal or better color gamut and efficiency than what was present on the previous-generation models.
The use of Quantum Dot technology for future MacBook Pro models was considered, but Apple did not opt for it due to being forced to use cadmium, a toxic element
On X, Display Supply Chain Consultants founder and CEO Ross Young said that regardless if customers purchase the version with the standard or nano-texture display, Quantum Dot technology exists on all M4 MacBook Pro models. Previously, he stated that Apple used red KSF phosphor film because it was less expensive and did not contain cadmium, which is toxic for humans. In the past, MacRumors reports that the technology giant’s executives explored the use of Quantum Dot technology but had to drop the idea due to the inclusion of cadmium.
Thankfully, there are now cadmium-free Quantum Dot displays that Apple can freely use in the M4 MacBook Pro models. These are considered better because they produce better image quality, improved color accuracy, and a wider color gamut. This major change might be the reason why the new machines boast a max SDR brightness of 1,000nits, up from 600nits in the previous models, but Apple has not specified this.
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.
