https://www.youtube.com/watch?v=rtd7UzLJHrU Comparison with the 40k display here. Apple doesn't come very close. Sure it's much cheaper. But then why compare.

Yeah, this, it really irks me how some people here keep parroting Apple's marketing without checking any facts/tests. Their monitor is great for a consumer or prosumer monitor but just because it has PRO in the name doesn't mean it can dance in the ring with the actual PRO displays that are used to master million dollar motion pictures.

In Apple's keynote announcing the XDR they literally called it the "World's best pro display" and then proceded to compare it to Sony's $40k reference monitor. I agree the comparisons are unfair and that at $5k it occupies an interesting price point in the market, but Apple did really bring it upon themselves.

So basically until displays advertise their physical specifications to Windows, and the Windows display stack takes advantage of that to auto-calibrate, it cannot match this kind of output. I wonder what happens if you try this on the LG 5K hooked up to a mac. It is physically the same panel that's in the iMac, so in theory it can present the same range. But if the OS needs to know the exact physical abilities of the…

I was just going to ask the same question. Everything is pointing to macOS working so well because they own the entire chain. Throwing in the external monitors that Apple promotes would suggest that Apple might also work as smoothly with it as their own. So one more test would be to use a really nice monitor not promoted by Apple.

Not exactly related, but I’ve been using macOS, Windows, and (for the last week) Linux all on the same LG HiDPI screen (4K, but small screen), and no matter how I try to wrangle Windows I just can’t get it to look good. It’s incredibly frustrating when you know how good the monitor can look.

Linux seems better somehow but I haven’t had as much time with it there, so I’m not exactly sure why.

It seems to me that Microsoft really makes no effort to improve subtle aspects of Windows and hardware integration. In fact, their OS is in such shambles and is a disoriented mess with respect to UI consistency. They introduced Vista, Metro, and now Fluent. Yet there's almost no coherence and the UI is now a mish-mash of XP, Metro, and Fluent era elements. By the time they announce their next UI, you can bet you'll n…

Latest Windows 10 iteration is by far the snappiest OS I've used in a long time since it uses GPU acceleration for the desktop window manager. You can check this in task manager. The icing on the cake, if you gave a laptop with 2 GPUS(Optimus) is when you can run a demanding 3D app like a game in windo…

What part of backward compatibility to run legacy software prevents UI uniformity?

> it's flawlessly undetectable in terms of brightness -- the interface white and grays don't change at all. In order to pull this off, you need to know exactly how many nits bright the display is, as well as having complete software control of the actual hardware brightness. On Windows, you have neither. Enabling HDR mode completely throws off your current colors and desktop brightness and you have to reset both your…

I tried, I have an LG UltraFine 5k connected to an 5k iMac (2019) it works on the iMac but not the LG.

This might explain why I’ve experienced a slight difference when working with photos and video on the iMac monitor vs the LG UF5k. Interestingly I have a small program synchronizing the brightness of my LG with the iMac, the LG would light up ever time I opened the video on the iMac and then come back down on closing. This might explain som weird brightness behaviors I’ve been noticing on the 5k every now and then, I use to decouple the syncing whenever that happens and now I might know why.

Wow, that's crazy, it actually works -- just tried out the sample videos in QuickTime on my 2016 13" MBP (P3 gamut, running Big Sur) and confirmed working. Basically: if I set my display to ~75% brightness and open the video, the whites in the video are 100% brightness, way brighter than #FFF interface white on the rest of my screen. But if I increase my display brightness to 100%, the whites in the video are the sam…

Am I missing something? The innovation is to ... dim LEDs so that full brightness is... more than 100%... https://youtu.be/4xgx4k83zzc

HDR specifies a brightness. Apple is playing HDR videos at the proper brightness when the rest of the OS might be turned down.

https://appleinsider.com/articles/20/08/03/what-hdr-hdr10-an...

That plus P3 gamut means a video playing on a display is closer to what a filmmaker intended.

https://en.wikipedia.org/wiki/DCI-P3

What's cool is: 1) 4-year old Macs have become HDR laptops and 2) the implementation is subtle- you get full brightness in the HDR video without having the rest of the UI blast to full brightness.

> since it uses GPU acceleration for the desktop window manager Uh, Windows started doing that in Vista .

WDDM's ability to do that has been progressively enhanced since Vista. Today's OSX is about where Windows was during Vista, and it really shows on Macs that are older, but still supported, usually shown via latency in normal situations, eg, just moving a window around on the screen (something every OS gets correct except OSX). Today's WDDM, however, is snappy as hell, even on my MBP from 2012, but OSX is, and always…

Quartz has been GPU accelerated since 2002 my dude

What are some other companies that also have this structure?

Not many. There was a very good comic about this a few years back. https://ritholtz.com/2013/07/organizational-charts-of-amazon...

That was drawn by Manu Cornet at Google. Here's his comic book about Google culture which includes that corp structure strip: https://www.amazon.com/Goomics-Googles-corporate-revealed-in...

Gotta be a point at which you decide to do a complete rewrite and ship a copy of the old OS in an emulation layer. That’s what Apple did with early OS X. Ship with a very well integrated Windows 2000 or whatever in an emulated container and be done with it

I had noticed this on my iPhone 11 Pro and I hate it. HDR doesn’t give you “whiter than white”, it just adds more steps of gray. White is white. White on a display is the brightest point the display can display. What Apple is doing, as the article explained, is showing regular white as gray. That’s not cool, that just stupid. It’s exactly what TVs at Best Buy do when showing SD vs HD content: They ruin the regular im…

The article says that if you turn your brightness up, the effect goes away. Is that true for the iPhone as well?

It’s not

The long-standing problem with Microsoft's internal culture is that it rewards people and teams for 'innovating' where innovation in many cases is just reinvention. I worked at Facebook for years and it now has a similar problem. Developers are evaluated every six months on their 'impact', which results in many dropping boring work and joining teams that are doing new things, even if they aren't needed.

Similar with Google. I'm amazed at how Apple can take something as old as typography, breathe new life into it, and make everyone shocked and awed. Another one: I have yet to use a trackpad as good as theirs. It's good because it doesn't have any moving parts. It's all haptic feedback.
