The current YT title “Triple-Screen Laptop DONE RIGHT” is still defendable, as it means doing the whole concept of 'Triple-Screen Laptop' in a way it is useful. I think the biggest issue is the current title on Hacker News: “DIY triple-screen laptop based on the framework”, as it is clearly not a laptop.
Well, even then I think the title is stretching it: to me the more sensible way to make a triple-screen-laptop-sitting-on-a-desktop is to just connect a normal triple screen setup via a docking station.
