I am working in windows 10 on an external monitor because I broke the screen on my computer. Now I need to enter the BIOS to install windows 11. But the BIOS is displayed only on the broken screen, on which almost nothing is visible. How can I display the BIOS on the external monitor?

    Seems like the internal screen is set to default during POST. If you have another computer with an M.2 SSD box, you can use WintoHDD to make a Windows installation directly on the SSD. Or bring that SSD to a PC repair shop and ask them to install Windows on that SSD.

    By default, your system doesn’t show BIOS on an external monitor. You need to make your external monitor as the primary monitor in windows which you probably didn't do . Go into the display settings and change that and then reboot the system as then you wil be able to see the bios settings. Good luck.

    The external display is the main one in the system. The BIOS was not displayed on it, but I didn't need it before

    The machine uses its screen as the primary one so BIOS will not show on the external screen. Disconnecting the broken screen might work (not sure about this). Or just do the upgrade to Windows 11 while you are in Windows 10.

    Yes, I believe the only way to have the external monitor as the default before the OS is loaded is to physically disconnect the internal monitor from the motherboard, and it's not assured that will work. For your Aspire C24-960 you can use this as a guide:

    Once the LVDS and backlight cables are disconnected, reassemble the rest in reverse order. At that point your all in one will act like a regular desktop, and only display on the external monitor.

    Thank you for your participation in my problem. Unfortunately, my windows does not work correctly to update to windows 11. A clean installation from a bootable media is needed. Disabling the matrix according to the instructions did not help. The external monitor starts working only when the windows desktop appears. In the settings, it is now the only one.

    So with the LVDS and backlight cables removed it still doesn't display anything on the external monitor during POST? The C24-960 shouldn't have any issues running Windows 11, why does it fail when doing the update from Windows?

    That's right. Nothing shows on external monitor during POST with LVDS disabled. Error occurs during windows update. Microsoft support recommends doing clean install of windows 11 from bootable USB media
