When people shop for a TV these days, a high-resolution, 4K screen is practically a given. But 4K computer monitors are still a luxury, unless you’re editing photos or videos professionally or you specifically want to watch 4K content.The Dell UltraSharp U2725QE is our favorite 4K monitor because it’s a quality, color-accurate display that can connect to and charge your laptop over USB-C, and it has superior contrast compared with other office monitors. The Dell UltraSharp U3225QE, our upgrade pick, is a larger, 32-inch version of the same display.For a less expensive option without USB-C, we recommend the Dell 27 Plus S2725QS. And for 4K gaming, we think the Asus ROG Strix OLED XG27UCDMG offers fantastic contrast and motion clarity due to its next-generation OLED display.If you don’t need a monitor with 4K resolution, you can find all kinds of great monitors and pay a lot less.
