So, screen says that it's about GNU Screen [verification needed], but then there's monitors which is about "Computer monitors (i.e. screens or displays)", and there's also display. Is common that people use them rather interchangeably which makes tagging hard. What should be done?
I confirm that screen is about Screen, the program, which is known as GNU Screen to the younger generations. monitors is about peripherals that turn a digital or analog electrical signal that represents a picture into visible light. display is a bit fuzzier: it's generally about the information flow from an application that wants to display something to the display hardware, including but not limited to the concept of displays in X11.
I don't see much misuse of the tags. We currently have 304 questions tagged screen, and 36 questions had the tag initially but no longer do. We may have missed a few, but not many by eyeballing the question list. That's an acceptable success rate.
