I'm not sure that this blog post author is trying to accomplish, possibly they are trying to use some other API besides Metal?
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 not mean “whole screen at 1000 nits for 8 hours”. But it would be nice to be able to use 1 hour of my work time to work in the park outside my apartment with a bright enough screen for that time.
The system has thermal capping implemented from what I saw in the CoreBrightness framework, so it should be safe as long as the system can detect that LEDs are starting to overheat and lower the brightness automatically.
"Vertically polarized light is preferentially refracted at the surface, so that the reflected light is left more horizontally polarized" and you use vertically polarised sunglasses to filter out the reflected horizontally polarised light.
This is a video I took last summer on this: https://files.alinpanaitiu.com/ff-polarized-macbook.mp4
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)
