You can set up something like mouse without borders or something that uses it as a over the network display or buy these controllers and make a custom case/mount/stand but in the end you're probably better off accepting you're better off buying a new monitor even though this one works great you "just" need to detach it from the laptop.
For as many that say "but I did and it works great" you don't really see many people going out of their way to get a laptop screen instead of a monitor prior to the cost already being sunk. That being said sometimes it's useful when you explicitly set out to build a budget custom video wall (11520x6480 52" can be had for cheaper than one might imagine) but usually you're buying specific panels at that point not finding yourself in possession of 9 of the same model laptop display by accident.
