Editor's Notes

November 12, 2018:

As you might anticipate, there aren't a whole ton of new displays at this size. Nonetheless, there are some recent releases that fit the bill, like the Acer and Asus options. The Planar is one of just two readily available touchscreens — ViewSonic makes the other, but it's just not put together too well. Many of these, like the HPs and Acers, make excellent VESA-mounted secondary monitors. And if you're using one of these to play games, at least you'll be know you won't need a bleeding-edge, high-powered rig to run the display.
