I know. I was just emphasizing how it was bothering me, and those computers have been in that thin wall since alpha. It's really just a nitpick.
I did say that I was thinking they could pass as being fake, but there was that one monitor that even if it were fake could not be there because monitors like that to be working they need a big box for the cathode rays or whatever (like old TVs). However, I have now realized (from looking at the screenshots) that it's actually not animated, and therefore, not a working monitor.
Oh well, but it's still gonna bother me anyway. ¯\_(ツ)_/¯
