Reviews of the M4 MacBook Pro generally align with my perspective that while it represents a solid choice for Intel MacBook Pro users, there isn’t a strong incentive for current M-series MacBook users to upgrade.
Nonetheless, it has come to light that Apple has discreetly equipped the latest MacBook Pro with enhanced display technology, bringing two significant advantages.
Display Technology in MacBook
The displays in MacBooks continue to utilize IPS LCD technology, albeit of a significantly higher standard compared to most other laptops.
Apple refers to this as miniLED, highlighting the enhanced backlighting design that incorporates a larger number of smaller LEDs, leading to improved local brightening and dimming features across the display.
While the core technology remains consistent with previous iterations, there has been a marked enhancement in both brightness and contrast levels.
Display Upgrade for M4 MacBook Pro
Earlier M-series MacBook Pro models relied on a red KSF phosphor film to enhance miniLED backlighting, thus allowing for a broader color spectrum than normally feasible.
This film was recognized for its efficiency, yet a superior alternative known as quantum dot is now available. Display analyst Ross Young has revealed that Apple has quietly integrated this technology into the M4 MacBook Pro.
Major news in Apple’s display offerings: they have adopted quantum dots for the first time. The latest MacBook Pro (M4) features a quantum dot (QD) film instead of the red KSF phosphor film.
Young states that this transition brings two notable enhancements for the latest models compared to their predecessors.
Improved color gamut and enhanced motion performance.
A commenter noted that tests confirmed the improved response rate.
When comparing side-by-side with TestUFO motion tests, the pixel response is visibly faster. You can visit an Apple Store and run testufo.com alongside the M1. The M4 LCD shows a clear speed advantage.
Reasons for Apple’s Delay
According to Young, Apple’s previous hesitance to adopt this technology stemmed from a combination of comparatively poor efficiency and the environmental concerns associated with earlier quantum dot generations that contained cadmium.
Previously, Apple favored the KSF solution due to its better efficiency and absence of cadmium (Cd).
Apple had expressed its reluctance to utilize cadmium back in 2015.
This element is classified as a human carcinogen by the World Health Organization, posing particular risks regarding the disposal and recycling of electronics that contain it.
Cadmium has detrimental effects on the kidneys and other systems, and it is classified as a carcinogen in humans. Although normally present in low concentrations in the environment, human activities have significantly elevated its levels, particularly in contexts that may expose the public. The recycling and disposal of electronic waste are of particular concern, especially for children.
