We've tested over 30 Dell monitors on our latest test bench. Dell releases a handful of monitors each year, usually towards the end of the year, and like many manufacturers, some of their most popular models tend to stay on the market for two to three years. Dell monitors range from basic 1080p monitors to the most advanced gaming or professional-grade monitors. Many Dell monitors target office users, and from Dell's website, it's even possible to buy monitors without stands or in kits, which is great if you want a multi-monitor setup on a mounting bracket.
The best Dell monitor for work with a 4k resolution that we've tested is the Dell S2722QC. It's a great office monitor with a few standout features, including USB-C support with power delivery, so you can charge your laptop and use the screen with a single cable. It also has a built-in USB hub, so you can leave your mouse and keyboard connected to your monitor, eliminating the need for dongles or a separate USB dock if your laptop only has a few ports. It also supports picture-in-picture and picture-by-picture modes, meaning you can view multiple sources at once. It's especially useful if you've been working from home and have a business and personal PC at the same desk.
It has great visibility in bright rooms, with high peak brightness and good reflection handling, so you don't have to worry about glare. It also has wide viewing angles, which is great if you often need to share your screen with someone else. Like most Dell monitors, it has excellent ergonomics and thin bezels, with a great stand that supports the monitor well. It's a great choice for a multi-monitor setup, as you can rotate it to portrait orientation in either direction, so you decide which way the down-facing inputs face. Unfortunately, it's not as well-suited for a dark room, especially if you prefer using a dark user interface, as it has low contrast, so blacks look gray in a dark room. It's a versatile monitor overall, and it's also the best Dell monitor for photo editing that we've tested.
The best Dell monitor for gaming with a 1080p resolution that we've tested is the Dell Alienware AW2521H. This compact 25 inch model has a flat IPS panel, and like most Alienware monitors, the build quality is excellent, with a stand that offers an impressive amount of ergonomic adjustments. It has good reflection handling and great peak brightness, meaning visibility won't be an issue, even in bright, sunny rooms. It stands out for its incredible motion handling. It has a 360Hz refresh rate and superb response time, resulting in smooth and clear motion in fast-moving scenes, as well as amazing responsiveness. There's a backlight strobing, but it only works within a narrow refresh rate range, and it isn't usable simultaneously with variable refresh rate (VRR). It supports G-SYNC natively but isn't FreeSync compatible, which might disappoint those with an AMD graphics card.
Unfortunately, while there's HDR support, there are some downsides because it can't display a wide color gamut, and the refresh rate at 10-bit color depth is limited to 300Hz over DisplayPort and 144Hz over HDMI. Also, despite having a better contrast ratio than most IPS panels, blacks still look grayish. On the bright side, it has a USB hub with four USB 3.0 ports, as well as an NVIDIA 'Reflex' feature that measures input lag and helps reduce it. Images remain accurate when viewed from the side thanks to its wide viewing angles, which is great for playing co-op games. Overall, this is the best Alienware monitor we've tested, and it's an excellent gaming monitor that should please most people.
If you prefer a gaming monitor with a higher resolution, then the Dell S2721DGF is the best 1080p gaming monitor for Dell that we've tested. It's different from the Dell Alienware AW2521H because it's slightly bigger at 27 inches, and the higher 1440p resolution delivers a more immersive gaming experience. Although you won't get the same 360Hz refresh rate, it still has a high 165Hz refresh rate, and it has native FreeSync support with G-SYNC compatibility to reduce screen tearing. It also has an incredibly fast response time that results in almost no motion blur, and it remains quick even when gaming at 60Hz. Also, you won't notice any delay while gaming, thanks to its low input lag.
Unfortunately, our unit has disappointing out-of-the-box accuracy, meaning you may need to get it calibrated to enjoy the most accurate colors, but this also may vary between units. It doesn't have an optional backlight strobing feature to reduce motion blur, but you likely won't need it anyway since the response time is so fast. It supports HDR10, but it doesn't add much because it doesn't get bright enough in HDR to make highlights pop, the contrast ratio is low, and even though it has a local dimming feature, it performs terribly and causes blooming around bright objects. Due to its IPS panel, it has wide viewing angles, and the excellent ergonomics make it easy to place in an ideal viewing position for co-op gaming. Overall, if you want a 1440p gaming monitor from Dell, you should be happy with this one.
The best Dell monitor with an ultrawide screen that we've tested is the Dell S3422DWG. It's a very good 34 inch monitor with an ultrawide, 21:9 aspect ratio. This wide-format screen is great for gaming as it delivers a more immersive gaming experience. The gentle curve makes you feel like you're part of the action and gives you a bit of a competitive edge in some games, thanks to the wider field of view. It delivers a great gaming experience, with low input lag and FreeSync variable refresh rate support, for a responsive, nearly tear-free gaming experience. It also has a great response time, although there's some dark smearing behind fast-moving objects.
It's also one of the best HDR monitors on the market. It has a high contrast ratio and good peak brightness in HDR, so blacks look black in a dark room, and bright highlights stand out in games without washing out the rest of the screen. It also has a great HDR color gamut, with excellent coverage of the DCI-P3 color space used by most current HDR content. It's also a good monitor for multitasking or office work, as the ultrawide format makes it easier to work with multiple windows open at once. Overall, it's a great choice if you're looking for an ultrawide monitor from Dell.
