Try pushing the larger display slightly further away until it covers the same field of view as the smaller display. Getting the display to 4+ feet away from your face will noticeably reduce eye strain. You don’t need your eyes to converge as much, and you don’t need to focus as close, leaving your muscles closer to their relaxed position. For work where you’re constantly changing your gaze from near to far (esp. e.g. working outside) or taking frequent breaks to walk around so your eye muscles are flexing back and forth, it’s not as big a deal, but if you’re in a relatively static position focusing close all day long, the extra distance is nice. (Actually, both those Dell displays you mentioned are pretty low resolution. If you get a chance, try some of the 200+ ppi ones. Makes a huge difference even for text/code.)
