    MicroLED not here [1], NanoRod OLED gone [2], QDEL not any time soon, QD Film ( used here ) isn't getting any better.

    I guess we have to stick to OLED for quite some time. I still dont think Tandem OLED is the solution for PC. Especially not when I have the monitor turned on for 16 hours per day and uses it most days of the year.

    I wonder if MacBook Pro will stick to LCD. While something like MacBook Air could switch to OLED just to be thinner.

    [1] For small display, for TV and signage they seems to be doing fine.

    [2] Samsung has reportedly given up on the idea. LG stopped R&D as well.

    M4 MacBook Pros use a quantum dot (QD) film rather than a red KSF phosphor film (twitter.com/dsccross)

    whats 'quantum' about it?

    • Etheryte 2 hours ago

      The color a quantum dot emits is defined by its size, larger dots are redder, smaller dots bluer. This is a quantum effect and happens due to their small size (a few nm each).

      It's about better gamut and sounding very futuristic, both with the aim of making the customer to pay higher prices for their products.

    Are the screen more sturdy than on the MacBook Air M1? I really didn't like my M1 dying overnight after 13 months, when the base warranty had just expired and apple asked me 67% (!) of the price of what I paid the M1 to fix the screen. I didn't and I use it as a desktop since then, hooked to an external monitor.

    For comparison, my LG Gram can be casually thrown down concrete stairs [1] and shall happily keep working.

    I'm not asking for something as incredible as that LG Gram's screen (from a reliability point of view) but I'd like to know if these newer MacBook laptops have screens less fragile than the first M1 laptops.

    [1] Not my vid but it's my experience with that laptop. Cat can jump on it, previous owner did step on it while waking up: do that to a Mac M1 laptop and it dies instantly. But my "MILSPEC" LG Gram: you cannot really damage that laptop (look at 35 seconds):

      Apple tried that with me when the screen died on my MacBook Pro M1. There is a law in the UK (Consumer Rights Act 2015) that says goods purchased must be fit for purpose for six years. I quoted this to support and they instantly agreed to fix it for free, sent me a box to put it in then collected it. I had it back within 2 weeks fully repaired and working again.

        good to know, I didn't know we had such a law. thanks for posting this

        Wait, so in UK products come with a six year warranty?

        • flir 16 minutes ago

          The consumer has a right to replacement or repair for six years after purchase in certain circumstances - see https://www.citizensadvice.org.uk/consumer/somethings-gone-w...

          I had a MBP mainboard replaced after four(?) years in a generation where the graphics chip was known for dying. Late 2012 maybe? That machine had so many replacement parts, I think it might be a ship of Theseus by this point.

      The deceptive problem with MacBooks is that they look sturdy, but aren't.

        my mid-2012 air would like a word.

        • Rinzler89 22 minutes ago

          2012 was 12 years ago when they were make like bricks and had all the ports. Let's see how current MacBooks will hold up in 12 years. I bet they won't be so lucky.

          Yeah I had a mid-2012 macbook pro and it lasted me almost 10 years, as a full time software dev that is. Replaced a fan, a cable and the HD to SSD, and the battery was over, but other than that kept going strong until I was sort of forced to upgrade because a newer iOS OS required a newer XCode required a newer MacOS required a newer laptop.

          I have to say it was fun anticipating my new laptop watching the benchmarks and observing like a 10x (multi core) improvement.

      My M1 is still fine after 3 years of usage, being dropped from 1m+ by my cat, and being sat on (while in a backpack though).

    Maybe they’ll finally release a good studio display

    • dijit 2 hours ago

      Studio Display is pretty good, for it's specs it's best in class. (It's basically just the 5k LG panel with upgrades to connectivity, post-processing and integrated speakers/webcam).

      I guess you're unhappy with the spec though? I haven't found any better 5K displays.

      • jim180 2 hours ago

        I've recently upgraded from LG 5K (dead pixels, warranty returned money) to Studio Display. I have never thought, how much I love reasonably (for a monitor) good speakers integrated into a monitor.

        Also, Studio Display is brighter (600 nits vs 500 nits).

      • vetinari 2 hours ago

        5K displays are very limit set in the first place. There is Studio Display, LG Ultrafine 5K and Samsung ViewFinity 5K. Samsung seems to be better value than Studio Display.

          I cannot find the LG one anywhere, I think it was discontinued.

          Build quality compared to the Apple display is quite different though.

          • vetinari an hour ago

            It is, but on the other hand, I would prefer to have plastic display with two inputs (since I have two computers; desktop and laptop) than aluminum one with just one input.

            • ErneX 12 minutes ago

              Agree, I would need at least two inputs at least.
