Look for in-plane switching (IPS) technology for the best screen quality. Desktop screens tend to be brighter than laptop displays in general, as well. Though it's not a concern to those with 20/10 vision, a larger screen and a higher native resolution will let you increase the font size on your Word documents or Excel spreadsheets while still keeping a lot of information on the screen at one time. Indeed, if you're a multitasker, the more screen room, the better. High resolutions of that kind give you the ability to view multiple windows side by side, or view a spreadsheet three to four pages wide. In many cases, that's up to 4K-3,840 by 2,160 pixels-for a conventionally shaped screen, or 3,440 by 1,440 pixels on an ultra-wide display. With a screen 23 inches or larger, you're almost guaranteed a native resolution of at least 1,920 by 1,080 pixels (aka, full HD), and larger screens will go even higher. The biggest all-in-ones we've seen to date have curved 34-inch screens. (Go much smaller than that, and you might as well just buy a big-screen laptop.) What you really want is a display at least 23 inches on the diagonal-and larger is better if you can do it.
While some less-expensive AIO PCs will come with panels smaller than 23 inches, those are better suited to exceedingly cramped spaces such as classroom labs or dorm rooms. The first thing to look at (no pun intended) is the display-the centerpiece of any AIO. Best Hosted Endpoint Protection and Security Software.
