Best ultrawide monitor
The Acer XR342CK is the most accurate 34-inch ultrawide, with a pixel count high enough to replace two monitors. Its 100 Hz refresh rate and FreeSync compatibility also make it a great choice for gaming.
The viewable space of the Acer XR342CK is just short of what you get from two 24-inch 1080p monitors. This monitor is huge, and the adjustable stand lifts, tilts, and swivels. Its two HDMI ports and DisplayPort offer plenty of ways to connect devices, and the four-port USB hub lets you easily keep cable clutter to a minimum. The XR342CK is the only ultrawide in this price range with a USB-C port that outputs 60 W, so you can connect and charge a modern MacBook Pro or Windows laptop with a single cable. And it supports a few nice-to-have features such as a faster-than-normal 100 Hz refresh rate and AMD’s FreeSync (it also works with Nvidia cards in our testing), which makes it an excellent choice for gaming. But the picture-by-picture mode on this Acer model doesn’t work as we expect, making the XR342CK a bad choice for two-computer setups. Although this model has an HDR mode, we recommend leaving that off because it makes everything look worse. And its three-year warranty doesn’t cover pixel failure like the warranty for our runner-up, the Dell U3419W, does.
Not as good for gaming but better for two computers
If you need to connect two computers to an ultrawide, the Dell U3419W includes a KVM switch and a functional split-screen mode.
If the Acer isn’t available, or if you want to connect two computers to one monitor, get the Dell U3419W. It’s as color-accurate as the Acer and has a similar selection of ports but typically costs more. Alongside a USB-C port that provides up to 90 W of power to a connected laptop, the U3419W has two upstream USB ports so you can connect two computers to the built-in KVM switch. (The USB-C port also works as an upstream port.) This Dell model’s picture-by-picture mode is much better than that of the Acer monitor, making the U3419W the more useful option if you’re replacing a two-computer, dual-monitor setup. Like Acer, Dell offers a three-year warranty, but Dell’s covers more, including replacing the monitor if a pixel dims or burns out.
