Question

laptops

Good day!
How can I completely turn off the laptop screen so that the image from the moment it loads goes to the second screen? Just turn it off to get a sort of stationary computer :)

Answer 1

Through personalization select that screen

Answer 2

Sometimes these settings are in the BIOS. If not, flash such a BIOS where it is. You can also try at the bootloader level - but this is already a perversion.
