This question What display size and resolution is good for reading PDF in double page view? is closed as primarily opinion-based. I attempt to edit it like this, but it says I'm editing too much. What do you think?
Also, I suggest we add some more tag: readability, x-height, screen-size.
The recommended distance between your eyes and screen is an arm length.
The arm length is around 60 cm (25 inch). At that distance, the x-height for easy readability is 3 mm (2 "sub-inch").
What display sizes and resolutions are the best suitable to read PDF books in double page view? Is 24" in 1900 x 1200 enough for that?
I currently have a 17" in SXGA.
