Can someone explain

I was reading this comment from Overheard in Minneapolis and I don't understand it. Can someone please explain?

Also, I think I should show this too my boss. I wonder how many monitors I could squeeze out of them. There's no way I have an 18" monitor. And the resolution on everyone else's monitor (besides mine) is set to like 600X800 or whatever the grainiest biggest oldest dumbest resolution is.

Sounds like it could be a fun work project for Lizzie.
