If you’ve tried to buy a nice Windows laptop in the past few years, there’s a good chance you’ve agonized over display resolutions.
Buy a laptop with a 4K display, and you’ll get a picture so sharp that individual pixels become indiscernible, but both battery life and performance will suffer as a result. Get a 1080p laptop instead, and you’ll get more battery life at the expense of that glorious picture.
There is, of course, a middle ground in the form of 1440p (2560×1440) displays, also known as QHD. You just wouldn’t know it from today’s selection of laptops. Even though 1440p hits the sweet spot between a crisp picture and long battery life, most laptops instead make you choose between extremes.
