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 85 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 Dell U2718Q is the best monitor for a dual setup that we've tested so far. The 27 inch, 4k display provides an excellent amount of screen real estate, which is great for multitasking. It can be VESA mounted, but the stand has great ergonomics and can easily be adjusted to the ideal viewing position without having to buy a dual monitor VESA arm.
This monitor has decent overall picture quality but doesn't look the best in a dark room, where blacks appear gray due to the low native contrast ratio. It performs much better in a bright room, with very good peak brightness, wide viewing angles, and decent reflection handling.
Unfortunately, although this monitor supports HDR, there's little benefit to using it in this mode, as it can't display a wide color gamut and can't get very bright in HDR. Overall, though, it's a very good monitor for almost any use and is a great choice for a dual setup office monitor.
If you want something cheaper than the Dell U2718Q, check out the Dell U2518D instead, 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 find the 24 inch Dell S2417DG small and want larger monitors for your dual setup, check out the Dell S2716DG; it has a 27 inch screen. You won't get the same peak brightness of the other Dell, but on the upside, it's an excellent monitor for gaming. It has a very fast response time and a 144hz refresh rate, so motion looks crisp with almost no blur. Unfortunately, like all monitors with a TN panel, it can't deliver deep uniform blacks in a dark room.
If you prefer a larger monitor and don't game in a dark room, get the S2716DG; otherwise, the S2417DG is a better choice.
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, the Dell U2415 is the way to go.
