How to completely turn off the built-in monitor when using an external monitor without the cover?

by Poster Apr 6, 2025 15
MacBook, you can close the internal screen when connecting the external monitor without the cover to save GPU rendering. The purpose is to use the built-in trackpad and keyboard (the external trackpad has the phenomenon of accidental palm touch). It is said that using magnets can turn off the inner screen, but at the same time the touchpad and keyboard are also disabled. Is there any solution at the software level now? The brightness is adjusted to 0. It seems that the GPU is still rendering.

    The software solution seems to only adjust the brightness of the screen, but it is actually not turned off. Magnets are placed on both sides of the keyboard to simulate the closed state and the screen will automatically turn off. Be sure to remember to put the magnets yourself. My last screen was pinched

    @ Anonymous6897 Using the cover of the iPad can avoid this problem 😂

    @ Anonymous6897 Then the trackpad and keyboard can't be used either

    @ Anonymous4835 @ Anonymous6897 I tried m3 macbook air. I put magnets on both sides of the keyboard and couldn't stop the screen. I went back and tried m3 16 'mbp at night.

    @ Poster It doesn't work anymore. Now it seems to have been changed to an angle sensor on the hinge. The magnet has been invalid

    Will mirroring cause a great burden on the GPU? It shouldn't be the case
