Overheating sounds interesting! So what happens if you display a max brightness hdr image on the screen for a long time, does the monitor shut off?

Edit: apparently at least on some laptops your screen may automatically adjust brightness downwards if you are in a hot climate and the cooling system fails to keep up: https://9to5mac.com/2022/02/04/macbook-pro-limited-brightnes...

Yes, the system monitors the display temperature and caps the brightness accordingly. Here are some interesting functions I found related to this inside the system frameworks:

    SkyLight.framework:
        SLSDisplayIsThermallyLimited
    
    CoreBrightness.framework
        -[CBDisplayModuleSKL hasThermalMitigation]
        -[CBThermalBrightnessCap getCurrentCap]
        -[CBThermalBrightnessCap setJetMode:]
