Will go to a graphic design school this year, what do you think is better?
17 "with 1920x1200px
Graphics programs always have a lot of interface, that's why it's so much better that you can see your work well without constantly scrolling.
I would recommend you 17 inches and at home a 27 inch screen, possibly with own computer or docking station for the laptop.
17 inch. Does not exist at Apple.
