Apple Says Pro Display XDR and 2021 MacBook Pro Can Experience Limited Brightness in High Temperatures

[Rygaard]

TBH I would expect products to work from 5ºC to 45ºC (not fluctuating between them but in a steady environment)
25ºC is not ok, my student apartment were getting 32ºC in the summer, and i live in Scandinavia, its freaking cold here.

And that is in the shade ofc. I would never expect a product to withstand even 25ºC ambient temperature and being in direct sunlight.

Living in a country where ambient temperature never drops under ~30 Celsius / ~90F this is a major PITA with the iPad Pro when trying to use it outside.

You're only 5 degrees under the maximum rated operating temperature for the iPad Pro at 30C:

Ambient operating temperature:
0° to 35° C (32° to 95° F)

and that's without the effect of sunlight hitting it. Not a massive surprise if you get issues in those circumstances, particularly if the brightness ramps up because the ambient light intensity is high so the display is generating more heat. There's no way round that, it's just physics.

TBH I would expect products to work from 5ºC to 45ºC (not fluctuating between them but in a steady environment)

See above, plus for the MacBook Pro:

Operating temperature: 10° to 35° C (50° to 95° F)

I don't think you're going to find any consumer electronics rated for an operating temperature of 45C (at least, I've never seen any).

I don't think you're going to find any consumer electronics rated for an operating temperature of 45C (at least, I've never seen any).

I'm not claiming that, but that is what I Expect as a consumer - But yes I often find I need to lower my Expectations

- its not that I do not understand the problems with cooling, and the hotter it gets the harder it will become to keep it cool, and if you get above say 50ºC or below 1ºC some materials starts to expand / shrink and that will open up a whole new set of problems - specially since different materials behaves differently.

And to those of you who are thinking Well Actually yes they also expand/shrink if going from 2ºC to 3ºC know

Lower your Expectations
Good, now
Lower your Expectations



Yes one more time EVEN lower

 

[ruka.snow]

Well I keep my rooms under 10°C so I am sure it'll be running good most of the time. Except maybe in summer where there is nothing I can do to keep the house under 15°C.

I don't find this to be unreasonable but I just really hope it's not a sign that these displays will degrade closer to OLED speeds than LED-LCD speeds.

I'm the type of person who has my laptop display at maximum brightness all the time. If they're allowing me to do it and giving me no indication that it could cause issues then it better not. ?

 

[Timster83]

i wonder if this monitor is going to start having issues in the long run.

Don't worry, you'll be able to buy v2 of the display. Compatible only with display stand v2 because the connector is 1mm bigger.

What will degrade fast if you use your laptop or any device continuously at maximum brightness will be your eyes, and those don’t have any apple care or warranty. Take care of them please.

 

[JosephAW]

Great, now they brought the problem (feature) of the iPhone screen dimming when hot to the desktop.

 

[bladerunner88]

"Heatgate".......Too Soon? ???

I appreciate your concern but there's no need to fret over displays. It's the sun where we should be taking precautions. My computer display maxes out at 500 nits. Though it cannot be directly translated, a cloudy day is equivalent to roughly 3,000 nits and direct sunlight around 10,000.

And unless you're looking directly at the sun, I'm pretty sure that any potential damage from visible light pales in comparison to damage (to both your eyes and skin) from UVR. Thankfully, modern displays don't emit UV. Neither do LED lightbulbs.

 

[BF1M]

This is unacceptable. I’m boycotting Apple and their products. Who is with me?

 

[Victor Mortimer]

Sounds like a non-issue. If the room is over 77 degrees, I'm not using the computer. I'm lying on the floor naked and sweating, with a fan blowing on me to attempt to cool down. I've already called the AC repair people once it got above 70.

Fortunately it's currently February, and my house is maintaining a very comfy 63 degrees.

 

[Basic75]

77F is what, 25C? That must be a joke! Hardware that doesn't work properly above 25 degrees?

The support document is saying that if it's doing this constantly when ambient is below 25C it's faulty, not that it will always drop the brightness when it's above 25.

Yes, I understood. It is not considered a fault if it drops the brightness when above 25C. That low of a temperature limit is a joke. My point stands.

Sometimes on iPad Pro, the screen suddenly dims. I have auto brightness off but the screen drastically dims during hot temperatures.

You are thinking of sheer light output but displays run in a propped up frequency in order to modulate a steady image to the eye. Unlike natural light this artificial emulation radiates differently and has to be accounted for. This is a problem in VR for example.

 

[svish]

Could occur if the room temperature is high. But don't think it is a big issue. Also don’t think it has to be kept at maximum brightness all the time.

 

[Attirex]

Cringey Intel ad mocking this incoming in 3..2...1...

 

[w5jck]

So basically, if you live in Texas, Florida, much of California (their home state), and any other place on the planet where temps tend to be over 77° F outdoors most of the year, don't take you new, overpriced Mac outside... Bwahahahahahahah!!!!! Major fail...again...

• Lower the ambient temperature of the room.

Apple: “You’re cooling it wrong”

 

[rungxanh2901]

Nice, I totally agree with the warning prompt. It's just common sense, nothing to complain about ?? If you're depleting your Mac with 1600 nits constantly watching HDR content, of course your Mac screen gets hot. It's reasonably sensible you would have to lower the brightness to ensure the longevity, for any kinds of screen, not just a Mac

 

[kalafalas]

Now let SDR brightness go above 500 nits, PLEASE. I don't need the full 1000, 800 like the iPhone is more then enough and even 600 like the iPad would be a meaningful improvement. Limit above 500 to high ambient brightness environments to avoid indoor eye strain just like iOS. I don't care if it dims out after some time/if its too hot (like the iPads and iPhones do) but even that 5-10 minutes of high brightness while I bust out a quick email while outside on my lunch or whatever would be huge. It can do it in HDR, why not SDR?

 

[FlyGuyDEN]

I've got two of these on order. I think its reasonable to expect the display to get hot if the sun is beaming down on the aluminum case. I'll just make sure to use it in the shade.

I’m visiting here from the YouTube comment section to say:

“That’s it! I’m switching to android!1!!”
I might also add:

“Auto screen-dimming when overheating. Another Apple innovation!!”

?

 

[CarlJ]

25 centigrade for anyone outside the US. Not particularly warm if you’re in summer with no A/C.

To be clear, though, they are saying if you get warnings under that temperature, then definitely get it looked at. They aren’t saying it will happen over that temperature.

Yes, I understood. It is not considered a fault if it drops the brightness when above 25C. That low of a temperature limit is a joke. My point stands.

The point is "if" it drops the brightness, which it will probably rarely do unless you are playing HDR content with mostly white pixels at full brightness. It's much more common on the iPad because of the heat from the logic board, but I often use my 2021 MBP in rooms well above 25C and with full brightness and has never seen it darken due to overheating. In fact, it rarely even feels warm to the touch.
