Thanks, makes sense. But why don't monitors have an "emergency" protocol to let the LEDs rest a while if we can know what's the max stress that they can handle?
So instead of burning out, I'd get a pop up saying that I should do something, or it lowers the brightness in that area or smth.
I have five guesses:
(1) That would require more diagnostics than an LED on a monitor is able to provide at a reasonable cost, (2) if you're leaving the monitor on in a situation where burn-in is likely, you're probably not at the monitor when it matters, (3) monitors are a mission-critical piece of hardware, meaning that them turning themselves off (or even just turning off certain pixels) randomly is not a great idea, (4) it's probably the OS's job to decide when to turn off the monitor, as the OS has the context to know what's important and what isn't, and how long it's been since you've interacted with the device, and (5) it's in the monitor manufacturer's best interest for your monitor to get burn-in so that you have to replace it more often.
The actual answer is probably a combination of multiple things, but that's my guess.
Honestly, setting a screen timeout (or even a screen saver!) is the solution to this problem. So the problem was more or less solved in the early 80s.
very good points, thanks.
