Why do you think so? 20 years ago, everything was clearly in 1X. Now, the Windows default for many resolutions is 1.5X and my Macbook is 2X by default. iPhones and Androids are at least 2X scaled by default. iPhones in the last 2 years (like iPhone 12 and 13 are scaled 3X. So we've gone from 1X only, to 2X pretty much everywhere for desktop, with 3X on the latest phones.
Full-HD monitors and laptops are still very common in the corporate world and for non-affluent PC gamers. I don’t see this lower-cost segment going away anytime soon, since display yield drops quadratically with DPI, and therefore the associated cost increases quadratically with DPI.
You can get a 4K monitor for ~$300 now - or significantly less if you shop deals. I spent that much on a super basic FHD display in 2016. Costs seem to be dropping pretty well even with inflation and the supply chain mess.
