You realize we are talking about a 2560x1440 monitor right?
Depending on your DPI settings, one can consider turning off subpixel smoothing at this res. At 4k you should certainly consider it. Plus, I'm sure various implementations are better than others. Does the iPad have this problem?
True, it's a 2560x1440 display, but it's not “retina“ yet. There is still a big difference with and without subpixel rendering, especially for smaller texts. Well, at least to my “retina” spoiled eyes. YMMV.
iOS does not use subpixel rendering at all, possibly due to the inconsistence of text rendering in different orientations.
