Dual monitor setups provide a great deal of freedom and make it much easier to multitask, as well as 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 is less space between the displays. Dual monitor setups can either be VESA mounted or simply displayed side-by-side on the same desk, in which case great ergonomics are a must.
We've reviewed over 90 monitors and below are our recommendations for the best monitors for a dual setup to purchase in 2020. See also our recommendations for the best office monitors, the best ultrawide monitors, and the best 34 inch+ monitors.
The best dual setup monitor we've tested so far is the Dell U2718Q. This 4k, 27 inch IPS monitor provides a clear image, good viewing angles, and decent color accuracy. The amazing ergonomics allows you to place the monitor however you like in the dual setup, including switching it into portrait mode. Image accuracy won't decrease when viewed from the side, so this monitor allows you to share your screen with co-workers without any problems.
This monitor can get fairly bright to combat glare, but reflection handling is mediocre. Unfortunately, because it has an IPS panel, the contrast ratio and black uniformity are okay, so when viewed in a dark room, blacks won't look that good. However, it has great coverage of the sRGB color space and covers the Adobe RGB color space as well, which photo editors will be happy with.
Overall, this is a great dual setup monitor because of its good viewing angles and amazing ergonomics.
If you want something cheaper than the Dell U2718Q, check out the Dell U2518D, which is still one of the best monitors for dual setup. This monitor is slightly smaller, but overall it's a good monitor for most uses. It has wide viewing angles, a flicker-free backlight, and great low input lag. Like the other Dell, it has very thin borders on four sides and it can be VESA mounted, which is great for a multi-monitor mounting arm. If you're not planning on VESA mounting it, the stand has great ergonomics, so it can easily be placed in the ideal viewing position.
Overall, the U2718Q is slightly better for most people, but if it's too expensive and you don't need a large monitor, the U2518D is a good alternative.
If you want a more immersive gaming experience, the Dell S2417DG is the best monitor for dual setup that we've tested so far. This monitor has excellent ergonomics, very thin borders, and can be VESA mounted, making it a breeze to place it in an ideal position.
This monitor delivers much better gaming performance than the Dell U2718Q. It has an outstanding response time, delivering crystal clear motion with very little blur, and it has an optional black frame insertion feature to further improve motion handling. It also has an extremely fast refresh rate and outstanding low input lag.
Unfortunately, it doesn't look quite as good in a dark room, as the TN-type panel can't deliver true blacks and has poor black uniformity. Overall, though, it's a great gaming monitor and a very good choice for a dual monitor setup.
If you want an even bigger monitor to deliver a more immersive gaming experience, then check out the Dell S2716DG. Its black uniformity is worse than the Dell S2417DG, but the two monitors have very similar performance, and the difference comes down to size. The larger monitor has a 1440p screen with a max refresh rate of 144Hz and supports G-SYNC variable refresh rate technology. It has an amazing response time with very little motion blur, plus the incredibly low input lag will please most gamers.
Unfortunately, the TN panel delivers a poor contrast ratio and there's no local dimming feature, so blacks look gray when viewed in dark rooms. If you're looking for the best dual setup gaming monitor, the S2417DG is a good choice, but if you want a bigger screen, look into the S2716DG.
If you're on a budget and want to build a dual monitor setup, then the best budget monitor for dual setup we've tested so far is the Dell U2415. It's a decent monitor overall, with decent brightness suitable for most offices and a low input lag, which is good for gaming. It has a 1200p resolution and a 16:10 aspect ratio that allows you to display more on your screen, minimizing the need to scroll up and down. Finally, its great ergonomics will allow you to place each monitor in the ideal position for your dual setup without much effort.
Unfortunately, just like most IPS monitors, it isn't the best choice for a dark room; blacks aren't uniform and look more like gray, and it doesn't support any advanced gaming features like FreeSync variable refresh rate to enhance your gaming experience.
Overall, if you want a set of decent monitors for building a dual setup that won't break the bank, this is the way to go.
