Apple defines retina as 220 dpi for laptops. WQHD at 14 inch is 210 dpi, so basically retina. FHD at 14 inch, the most common resolution these days, is 157 dpi, and quite clearly not retina.

Another big difference is aspect ratio. Lenovo ships 16:9 displays. WQHD gives an effective vertical resolution of 720px at 2x. FHD at 1.5x is also an effective vertical resolution of 720px, or 864px at 1.25x. Apple on the other hand ships 16:10 displays with an effective vertical resolution of 900 px at 2x. That means a 13 inch macbook pro fits more lines of code on the screen than a 14 inch FHD or WQHD thinkpad.

LInes of code on the screen … How small do you make your font size? I mean, it must be pretty small, so that you cannot read it with one display but can read it with a so called retina display.

Not sure that's practical at all and thus whether it makes any difference.

I feel you may be looking at this through too narrow of a lens since it's not just about lines of code, though that's one part of it. I think the point is that a 13 inch Retina screen can fit more "stuff" than a 14 inch non-Retina FHD/WQHD screen.

Sorry for not making it clearer. I meant lines of code the same apparent size, whatever your preferred size is.
