Brightness issue on M1 Pro Macbook Pro 16inch. Is this normal?

[applegoldfish]

Any difference if you plug it in?

A little brighter, but still ASD is miles ahead in brightness.

Also, the screen lights up differently on MBP and ASD as you increase brightness. I mean, on ASD it's a sharp increase/burst of light whereas MBP screen lights up very subtle on increasing the brightness.

Is there a store with an Apple MacBook Pro on display that would be similar to yours? If so, you could take yours in and do a comparison.

The brightness curve is never the same.

True tone was on though... had both on half brigthness. Here it looks the MBP is even lighter.

In normal use it is more or less the same. Yes, totally different displays but in daily use it would say they are more or less equal.

104F outside 77F inside the room

40 degrees outside, but inside the room it's 25 degrees.

As others have said, you can't compare x notches on one display with x notches on another. Their scaling is likely non-linear. You should instead compare them at maximum brightness (and with both plugged in)

If the new MBP remains dimmer than the old one at max brightness, check the display specs for each. If the new MBP is supposed to be as bright or brighter, but it's not, then it's worth looking into thermal throttling. The article I linked says: "Apple says that users who see this problem continually when the ambient temperature of the room is under 77 degrees Fahrenheit should contact Apple Support for help." Thus it sounds like 77F is right at the border where this thermal throttling can happen.

To check if this is thermal throttling, you could temporarily lower the room temp to ~72F, and also point a fan at the laptops, and compare brightness again.

Thank you for sharing. I have the opposite scenario. ASD is way brighter than MBP's. Will look into it further.

Thanks once again for taking the time.

Yes, I will check with lowering room temperature. Thanks for your input.

Why don’t you just call Apple support instead of accepting unsupported claims made by anonymous people on the internet?

Why don't you actually bother to read the discussion before you come here and start trolling?

I did support what I said, with post #19.

And it's best to do your own investigation before calling Apple support, since they're more likely to be able to help you if you can provide more information about what's going on (so long as that investigation is non-invasive, which my suggestions were). But that requires actually doing work on your own, a concept that's obviously foreign to you.

This is top on google, so I'll leave the solution here:
Go to Settings -> Displays, scroll down to Refresh Rate section and choose whatever rate is not chosen right now, then switch back -- the brightness will be 100% again. Some hardware bug I assume.
