There are several reasons why this is even a question.
So why is this even question again? Well, monitors usually come with a standard warranty. It’s helpful to know if the warranty has expired or not if a monitor has failed. Does this require tracking the serial number of every single monitor?
I don’t go to the cinema often anymore – I’d rather just pop in a disk and get the biggest monitor you’ve got, and if the quality is superb, I can watch a film, and if I don’t like it I can pop it out. ~Ridley Scott
The advice we usually give is to track any monitors that are “special” or expensive. If the monitor is unique and should always be assigned to a specific computer or owner, it’s probably worth tracking by serial number. Usually, large screen displays, such as those in a conference room, are also worth tracking.
Tracking the standard monitors in your environment may not have a good Return on Investment (ROI). Remember that every time a monitor moves, it should be updated in your asset repository. This includes creating records for every monitor in your environment to get started.
