DevMan Tag curator Monitors - please help!
There is a laptop.
You need to turn the laptop display into a monitor of another PC (immediately after turning it on)!
Is it real or not?
UPD: task: to use the laptop as a laptop, and as a monitor for another PC (immediately after turning it on and without opening the case). (....maybe there is something hard that can be adapted using standard ports and connectors?!)
