[FilterSweep]

Displays can always be used for other purposes, as well. And, with 4K only being marginally better at certain viewing distances for its price point[0], there is plenty of time where this display can be reused. Most other components can also be reused. I bought a 24" display to set up a RPI gaming rig and now that I don't have time to play with it anymore, I may reuse this display as an "RPI Home Digital Assistant" (future project which I'll probably never get around to implementing).

My only concern is power expenditure - I have minimal knowledge of kWh price of using such a display.

But all in all, some people really like these DIY projects - and others don't. Nothing wrong with that!
