The M4 MacBook Pro reviews have largely confirmed my own view that while the machine will be a great buy for Intel MBP owners, there's no compelling reason for any M-series user to upgrade.
However, it turns out that Apple has quietly equipped the latest MacBook Pro with new display technology that offers two benefits:
MacBook display technology
MacBook displays still use IPS LCD screens, albeit much higher quality ones than those offered in most laptops.
Apple describes them as miniLED is a reference to the significantly improved backlight, which uses many more smaller LEDs to provide much greater localized brightness enhancement and display dimming.
So while the underlying technology is unchanged from previous models, there is a noticeable improvement in brightness and contrast.
M4 MacBook Pro gets a display upgrade
Previous M-series MacBook Pro models used KSF red phosphor film, which allows miniLED backlighting to produce a wider color gamut than is typically possible.
This film is also very efficient, but there is an even more efficient film known as quantum dot. Display analyst Ross Young reports that Apple has quietly implemented it in the M4 MacBook Pro.
Big Apple display news: They have used quantum dots for the first time. The latest MacBook Pro models (M4) use quantum dot (QD) film instead of KSF red phosphor film.
Yang says this gives the latest models two advantages over earlier models.
Better color gamut and better motion performance.
One commenter said tests confirmed faster response times.
The pixel response is obviously significantly faster when comparing TestUFO motion tests, you can go to the Apple Store and run testufo.com compared to the M1. The M4 LCD is noticeably faster.
Apple had good reason to wait
The reason, according to Young, is a combination of relatively low efficiency and the fact that previous generations of QDs contained cadmium.
In the past, Apple used the KSF solution due to its better efficiency and lack of cadmium (Cd)
Apple commented on its reluctance to use cadmium back in 2015.
The World Health Organization classifies the element as a human carcinogen, and there is particular concern about recycling or disposing of electronics containing the metal.
Cadmium is toxic to the kidneys, as well as to the skeleton and respiratory system. It is classified as a human carcinogen. It is normally present in the environment at low concentrations; however, human activities have significantly increased levels in environmental media relevant to population exposure. Factors that may pose particular risks to children include the disposal and recycling of electronic and electrical waste.
