The best dual screen monitor setups provide a great deal of freedom, make it much easier to multitask, and provide a more immersive gaming experience. When shopping for monitors for a dual setup, the selection criteria are a bit different. Most people 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.
We've tested over 220 monitors, and below are our recommendations for the best monitors for dual setup to buy. See also our recommendations for the best office monitors, the best ultrawide monitors, and the best vertical monitors.
The best monitor for dual setup we've tested for office use is the ASUS ProArt Display PA278CV. It's a great monitor, with a 27 inch, 1440p screen that delivers decent text clarity. It's impressive for office use, with wide viewing angles, superb ergonomics, and great connectivity. It also has a built-in USB hub, with four USB 3.0 ports and a USB-C input. It also has a DisplayPort Out port that's supposed to allow you to daisy-chain multiple displays, but we couldn't get it to work.
It has excellent gray uniformity and impressive gradient handling, so you don't have to worry about dirty screen effect or banding in areas of similar colors. It has excellent accuracy out of the box, great if you rely on accurate colors. It also has a very versatile stand with fantastic ergonomics, so if you decide to mount it vertically, you can rotate it in either direction.
Sadly, the ASUS has mediocre contrast, so it's not the best choice for a dark room, and it doesn't support HDR. Overall, this monitor is the best for a dual monitor office setup that we've tested.
If you prefer a 4k resolution, check out the Dell S2721QS. Like the ASUS ProArt Display PA278CV, it's also a 27 inch IPS monitor, but it delivers a much sharper image and much clearer text thanks to its 4k resolution. It has very good ergonomics and thin bezels, making it a great choice for dual setups. On top of that, it supports HDR, but although it can display a wide color gamut, HDR doesn't add much. It doesn't have any USB ports, but you do get a Picture-in-Picture mode, a feature that lets you display two input signals simultaneously.
If you don't mind a 1440p resolution, the ASUS is better because it has superior ergonomics and more features. However, the Dell is a great alternative if you need a higher resolution.
The best dual monitor for gaming we've tested is the ASUS VG279QM. It's a great monitor with excellent gaming performance, with an extremely fast refresh rate and an outstanding response time, resulting in crystal-clear motion with very little blur behind fast-moving objects. It has native FreeSync support to reduce screen tearing, and it's G-SYNC compatible as well. Input lag is very low if you game at its max refresh rate, but it increases at 60Hz, so it's not the best choice for console gaming.
It supports HDR, but it can't display a wide color gamut, and its contrast ratio is mediocre. It has very wide viewing angles and outstanding ergonomics, so the image remains accurate even if you can't place it directly in front of you. It also has great peak brightness in SDR and decent reflection handling, so visibility isn't an issue in a bright room.
The 1080p resolution may be limiting for some as text clarity is only decent, but it isn't as demanding on the graphics card, making it easier to achieve higher frame rates in games. If you don't mind a smaller screen, the ASUS TUF Gaming VG259QM has a higher pixel density and performs similarly gaming-wise. Regardless of this, the VG279QM is the best dual monitor setup for gaming.
The best secondary monitor that we've tested in the budget category is the ASUS ProArt Display PA278QV. It's a 27 inch model with a 1440p resolution and a 75Hz refresh rate. It means you get plenty of room for multitasking, text looks sharp, and the monitor feels a tad more responsive than a typical 60Hz display. It has wide viewing angles that make it great for sharing content, and it gets bright enough to provide good visibility in well-lit settings.
It has quite a few extra features. There's a USB hub with four USB 3.0s and a USB-B upstream port, which means you can plug your peripherals or dongles into the monitor and have only a single USB cable leading 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.
Like most IPS panels, it isn't ideal for dark rooms because it has a mediocre contrast ratio that makes blacks look gray. Also, it doesn't cover the entire sRGB color space even though it's designed for content creators, which might be disappointing for some. On the bright side, its response time is good enough for some light gaming on the side, and its ergonomics are superb. Overall, it's a great budget-friendly monitor that should please most people.
If you want a true gaming monitor with better motion handling and responsiveness, then check out the Gigabyte M27Q. Like the ASUS ProArt Display PA278QV, it's also a 27 inch model with a 1440p resolution. However, it has a 170Hz refresh rate and a quicker response time to make fast motion look smoother and deliver a more responsive gaming experience. It has full sRGB coverage, supports HDR, and includes more features, like USB-C input and a Picture-in-Picture mode. Unfortunately, it has worse ergonomics because it doesn't allow for swivel adjustment or rotation to portrait mode. Also, it has a BGR subpixel layout that may cause blurry text in some applications.
If you only use the monitor for work, go with the ASUS because it has better ergonomics, and its standard RGB subpixel layout is less likely to cause blurry text than the BGR subpixel layout on the Gigabyte. However, if you're looking for a high-refresh gaming monitor, then go with the Gigabyte.
