How to remove laptop screen completely and use external monitor?

[Williamhawk]

Hello,

How to remove laptop screen completely and use external monitor?
One of my old laptop screen is broken. I want to reuse the laptop with new external monitor (no internal).
When I remove the laptop screen, it won't detect the external monitor.
Should I remove the primary screen from boot menu or there is some more hardware removal needed?



I didn't find the right solution from the internet.
