Setups with dual-screen monitors provide a great deal of freedom, making it much easier to work with multiple windows open. When shopping for monitors for a dual setup, the selection criteria are different than if you were looking for a monitor on its own. You'll want to look for great ergonomics to easily adjust the screen, and it's also beneficial to get a display that supports daisy chaining so you can connect it directly to another monitor. However, if you get two monitors that don't support daisy chaining, you can still connect two HDMI or DisplayPort cables directly from your computer.
We've bought and tested over 265 monitors, and below are our recommendations for the best monitors to buy for a dual setup. See our recommendations for the best work monitors and the best vertical monitors, and if you prefer one larger display for multitasking, check out the best ultrawide monitors.
The Dell U2723QE is the best monitor for dual setup we've tested. While its 27-inch screen size may seem big with two of them placed side-by-side, it's a great size for multitasking, and it's also easier to find 27-inch displays with good performance compared to smaller screens. It's an impressive office monitor with many features and delivers clear text thanks to its 4k resolution. It has thin bezels and remarkable ergonomics, meaning it's easy to adjust to your ideal viewing position. It has a ton of connectivity options, including a DisplayPort output, meaning you can send a 4k @ 60Hz signal to a secondary monitor, which helps keep your setup clean with fewer cables.
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 want to use it in a well-lit room.
If you want the best secondary monitor in the mid-range price category to save some money, consider the ASUS ProArt Display PA278CV. It has a lower 1440p resolution compared to the 4k resolution of the Dell U2723QE, meaning text isn't as sharp, but that's the sacrifice you need to make for getting something cheaper. However, getting two 1440p displays is easier on your graphics card than two 4k displays. This monitor supports daisy chaining, meaning you can connect a second monitor, and it has a USB-C input that makes it easy to connect a laptop and charge it at the same time.
It has outstanding ergonomics as you can swivel it 45 degrees in each direction and even rotate it into portrait mode, making it easy to adjust next to another display. It also gets bright enough to fight glare, and the reflection handling is decent, so visibility isn't a problem in most well-lit rooms. It has remarkable accuracy before calibration, so you don't need to calibrate it for accurate colors. However, it doesn't support HDR, so if that's important to you, the Dell UltraSharp U2520D is another 1440p option that supports HDR, but it has a slightly smaller screen.
If you want something on a budget, there are plenty of good options available, although you might not get the same features and inputs as higher-end monitors. If that's the case, the Dell S2721QS is a great choice because it offers excellent office performance, thin bezels, and impressive ergonomics, as you can easily adjust the screen. There are a few differences between this and the ASUS ProArt Display PA278CV as it's a 4k monitor with sharper text, but it doesn't have the extra features like a USB hub with a DisplayPort output. You need to connect your PC directly to both monitors or use another monitor that supports daisy chaining if you want to use this in a multi-monitor setup.
Like the ASUS, it also gets bright enough to fight glare, the reflection handling is good, and it has wide viewing angles that make it ideal for sharing your screen with someone else. It doesn't have the same color accuracy as the ASUS, but it's still decent if your work doesn't require perfectly accurate colors.
If you're looking for the best secondary monitor for cheap, check out the ASUS VG246H. There are some trade-offs you need to make by getting something cheaper, like the fact that this monitor has a lower 1080p resolution compared to the Dell S2721QS. It means that text doesn't look as sharp, but the text clarity is still decent. It also has a smaller 24-inch screen; however, that makes it easier to put two monitors next to each other if you have a smaller desk. It doesn't have a USB hub or DisplayPort output, so you have to make sure your computer has two video outputs so you can connect two monitors.
Besides that, this monitor offers good office performance for its cost as it has remarkable ergonomics, allowing you to easily adjust the screen how you want. It also has wide viewing angles that make the image remain the same from the sides, and it's good if you want to use it in a moderately-lit room as it has good reflection handling and decent peak brightness. However, if you want something that gets even brighter, consider the Acer Nitro XF243Y Pbmiiprx, but it can be harder to find than the ASUS at times.
