Setups with dual-screen monitors provide a great deal of freedom, making it much easier to multitask with multiple windows opened. When shopping for monitors for a dual setup, the selection criteria are a bit different than if you were looking for a monitor on its own. You'll want to look for thinner bezels, so there's less space between the displays. Dual monitor setups can either be VESA mounted or displayed side-by-side on the same desk, in which case great ergonomics are a must.
If you just want extra screen space, ultrawide monitors are a great alternative to buying two small monitors because you don't need to use extra wires on your desk and you won't get bezels in the middle of the screen. If that's something you're interested in, then check out the best ultrawide monitors.
We've bought and tested over 240 monitors, and below are our recommendations for the best monitors for dual setup to buy. See also our recommendations for the best work monitors, the best budget monitors, and the best vertical monitors.
The Dell U2723QE is the best dual setup monitor that we've tested. It's an impressive office monitor with lots of features and delivers clear text thanks to its 4k resolution and high pixel density. It's the best dual monitor you can get, thanks in part to its thin bezels and remarkable ergonomics, meaning it's easy to adjust to your ideal viewing position as you can swivel it 45 degrees in either direction or even rotate it into portrait mode. It has a massive USB hub, and one of its USB-C ports supports daisy chaining, and you can send a 4k @ 60Hz signal with 8-bit color depth to a secondary monitor with it. It's great because you'll only have one cable from your PC or laptop to the U2723QE and another to the other display.
If you need to connect multiple devices to your dual monitor setup, this display is also a great choice as it has a KVM switch. It means you can connect your mouse and keyboard directly to the monitor and control both devices with it. In terms of picture quality, it displays a wide range of colors with excellent accuracy, and even though it has disappointing reflection handling, it gets bright enough to fight glare.
If you find the Dell U2723QE too expensive and want something cheaper while keeping many of the same features, then a mid-range monitor like the Dell UltraSharp U2520D is a good choice. It's one of the best monitors for dual setup because it has a smaller 25-inch screen, which is great if you want to buy two to place side-by-side and have limited desk space. While it has a lower 1440p resolution than the 4k resolution of the U2723QE, the text clarity is still good. It also has wide viewing angles and excellent ergonomics if you don't view the screen from directly in front and want to adjust it.
It has a good selection of inputs with three USB ports and a USB-C input that supports DisplayPort Alt Mode, which is ideal if you want to connect a compatible laptop and charge it at the same time. It also supports daisy chaining via DisplayPort, making it easy to connect a secondary screen. Lastly, colors look accurate thanks to the sRGB mode, so you won't have to worry about calibrating it.
If you're on a tighter budget, you can still find great office monitors for dual setups, and the best secondary monitor we've tested in the budget category is the ASUS ProArt Display PA278QV. It's a 27-inch model with a 1440p resolution, meaning you get plenty of room for multitasking, and text looks sharp. It has wide viewing angles that make it great for sharing content with someone next to you, and it gets bright enough to provide good visibility in well-lit settings.
There's a USB hub with four USB 3.0 ports and a USB-B upstream port, which means you can plug your peripherals into the monitor and have only a single USB cable going to your PC, giving you extra ports and keeping your setup clean. It also has built-in speakers and a Virtual Scale feature that lets you preview documents in their actual sizes before printing. However, unlike the Dell UltraSharp U2520D, it doesn't support daisy chaining, so you need to connect your laptop or PC directly to the monitors. If you want something with daisy chaining support, the ASUS ProArt Display PA278CV is a similar monitor that supports it, but it costs more, so it's better to stick with the PA278QV if you're on a budget.
Cheap monitors are a great choice if you need to buy two at a time or multiple to supply your employees, and some offer good office performance. If that's something you're interested in, the ASUS VG246H is the best cheap monitor for dual setup that we've tested. At 24 inches in size, this small screen is great if you don't want to take up a lot of space on your desk with them placed side-by-side. Despite its low cost, it has good office performance with remarkable ergonomics as you can swivel it a full 90 degrees in either direction, tilt it, adjust the height, and rotate it into portrait mode. It also has wide viewing angles that make the image remain consistent from the sides.
As expected for a cheap monitor, it has a limited section of inputs as it only has HDMI and VGA ports, but as long as your laptop or PC has either port, you can connect to it. It even has built-in speakers if you want to listen to music during work and don't want to spend extra on a dedicated setup. Even though the SDR peak brightness is only decent, it still has good reflection handling if you want to use it in a well-lit room.
