While the more visible trend among TVs is ever-larger screens, you'll also find more options on the smaller end of the scale, and in particular 4K models at the 42" screen size, which truly straddles the line between PC monitor and TV.
A 42-inch TV is equally useful on a home office desk, a bedroom dresser, a garage workbench, in a kitchen, or a dorm room. It's a TV that's light enough to pick up and move, but large enough to enjoy the detail found in 4K. New in 2022, there's even a 4K OLED option at this size.
