I would imagine below $200 you’ll be looking at 1080p. If you’re willing to spend a bit more you can get substantially more resolution.
At $291 shipped (don’t get distracted by all the used offers) this is an awesome 27" IPS panel (matte) with 2560x1440 and LED backlight, slim bezels all around, and lots of inputs. I’ve been using it for about two years (after several ACDs and a couple years on a similar display form Samsung) and I have nothing but the highest praise for it. I find my self plugging it a lot these days (feels a bit weird since I can’t stand Dell as a company) but I really think this is a terrific display, especially for Mac users (note: TB3 not required).
