Does anyone know how to read or measure the brightness of a screen? I wasn’t able to get the reading the author has from Console.app
On an M1 you can run the following:
ioreg -r -c AppleCLCD2 | grep -i nitsIs there a technical reason for not enabling going beyond 500 nits when a user just ramps screen brightness? I'm no expert but if that can peak at 1600 nits for a while, it should have been able to sustain 800-1000ish for quite a long time?
A lot of non-technical users might get used to that brightness and then start complaining about their display dimming by itself randomly.

I think that long time might not be higher than an hour or two given how much heat the LEDs need to dissipate. A lot of non-technical users might get used to that brightness and then start complaining about their display dimming by itself randomly.
If they can't sustain their sustained brightness, that might even be false advertising.
Isn't like ... 200 nits ... a healthy upper limit for looking at a screen all day?
Isn’t this highly dependent on the ambient light around you?
Thus, I'm assuming indoors.

I’m not trying to draw HDR content. I want to increase to overall UI brightness (basically, make the brightness of where backlight LEDs go past the software defined limit) I’m testing Apple’s claim of 1000 nits sustained brightness which led many people to believe that they can finally use their laptop in direct sunlight without squinting at the screen. I’m aware of thermal limitations and that even sustained might n…
> I’m testing Apple’s claim of 1000 nits sustained brightness which led many people to believe that they can finally use their laptop in direct sunlight without squinting at the screen. How about increasing the brightness of just the text, and not the background, like https://kidi.ng/wanna-see-a-whiter-white ? No reason to crank up the brightness for the background as far as I can see.
But this can’t be done either. That website has the whiter-than-white text because it chose to do that. It’s known that every app has the possibility of rendering HDR content at more than 500 nits.
The problem I was trying to solve is how to do that from the outside, on apps that haven’t implemented HDR logic (which is about all of them)

He's using an Apple laptop. If he's trying to work outside... i'd like to know how long till his keyboard breaks from the tiniest speck of dust. Thus, I'm assuming indoors.
The current MacBook keyboards are quite nice, they have the same mechanism as the external Magic Keyboard sold by Apple, and they seem quite resilient. I had no stuck key in the last 2 years.
I had sometimes problems with color management on mac on fullscreen videos and to prevent that I put a small window from Helium or Pennywise (always on top browsers) into some corner to fix it.

The butterfly keyboard mechanism responsible for breaking on dust particles is gone on newer laptops. The current MacBook keyboards are quite nice, they have the same mechanism as the external Magic Keyboard sold by Apple, and they seem quite resilient. I had no stuck key in the last 2 years.
Note that I bought the 2018 or 2019 model with extra isolation under the keys. That didn't help at all.
Idea: create a small web browser or movie player app which plays a 1x1 nearly invisible HDR video in some corner and get the nits limit higher.

You use it outdoors? I'm typing this on one of the emoji keyboard laptops and it works so "well" that I'm not in a rush to give Apple more money for a portable... Note that I bought the 2018 or 2019 model with extra isolation under the keys. That didn't help at all.
The keyboard worked perfectly fine.
I haven’t had a chance to test the 2019 Intel MacBook too much, but the M1 2020 was heavily used outdoors. I believe the M1 2020 model was the first one to get the Magic Keyboard mechanism: https://support.apple.com/kb/SP824
