Switching screen when installing debian (deepin)?

Question

Debian

Hello! There is an asus x553ma laptop with a broken display and a whole connected monitor, I decided to install deepin, when the installation opens, the installation window is transferred to a broken display, I tried everything fn + f .. does not work, as well as dragging the screen blindly. What to press, do something to move the installation window to the 2nd screen?

Only one clumsy option comes up - to disassemble the laptop and disconnect the monitor from the motherboard (look for a thick shielded cable coming from one of the hinges of the lid inward.)
