We've reviewed nearly 20 Dell monitors. 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 2-3 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, great if you want a multi-monitor setup on a mounting bracket.
The best Dell monitor we've tested so far is the Dell U2718Q. This is a 27 inch 4k monitor that provides excellent text clarity, and its simple, minimalist design fits into any office setting. The stand offers excellent ergonomics so you can adjust it to your optimal viewing position, and the thin bezels are great for a multi-monitor setup. With an IPS panel, it has good viewing angles so you can share your work with colleagues easily, but unfortunately, its low contrast ratio makes blacks look gray, although it's typical for this type of panel. It has a good peak brightness that makes it suitable for use in bright rooms, but it's best to avoid placing it opposite a window, as its reflection handling is rather mediocre.
This monitor has good response time and low input lag for a good desktop experience. While gaming feels responsive, its refresh rate is limited to 60Hz and there's no support for any variable refresh rate technology. It supports HDR; however, it can't display a wide color gamut and it can't get bright enough to make highlights pop. On the upside, it has a 10-bit panel with superb gradient performance, and it has an excellent SDR color gamut, with outstanding coverage of the sRGB color space, as well as a good Adobe RGB coverage, which is great if you need to do some light photo editing.
There aren't many extra features on this monitor, but it does have a USB hub built-in that supports fast charging, and it can be used even when the monitor is in standby mode. Overall, this is a versatile monitor that can handle any task and it's a great choice for anyone looking for a high-resolution monitor for work, whether it's at the office or at home.
The Dell U3818DW is the best ultrawide Dell office monitor that we've tested so far. It's a monitor with a 21:9 aspect ratio, which is great for multitasking, and it has a resolution of 3840 x 1600 to deliver detailed images and sharp text. It has an IPS panel with wide viewing angles and it has a slightly curved screen that can help with visibility. Build quality is very good and its ergonomics are decent for an ultrawide, although it can't rotate to portrait mode due to its aspect ratio. If you work in a well-lit room, this monitor can get bright enough to combat glare and it has great reflection handling too. Unfortunately, it isn't as well-suited for dark rooms due to its low contrast ratio and sub-par black uniformity, although it's expected of most IPS panels.
Out-of-the-box, this monitor has excellent color accuracy and it can display the entire sRGB color space; however, it doesn't support HDR. It has a Picture-by-Picture mode that allows you to display two sources at once, and It also functions as a KVM switch, so you can use just one set of mouse and keyboard to control both devices. It comes with a USB hub that includes four USB 3.0 ports, and there's a USB-C port that supports DisplayPort Alt mode, allowing you to display an image from a compatible device and charge it at the same time with a single cable.
If you want to do some gaming on the side, this monitor has a low input lag and a fast response time, but there's no support for FreeSync or G-SYNC, and it has a 60Hz refresh rate. On the whole, it's a good ultrawide monitor for most people, with plenty of screen real estate to work comfortably and efficiently.
If you want an even larger monitor, check out the Dell U4919DW. This massive 49" monitor is the equivalent of two 27", 1440p monitors side-by-side. This delivers an impressive amount of screen real-estate, great for multitasking. It also supports picture-by-picture, so you can work with multiple sources at once.
Overall, the U3818DW is the best Dell office monitor that we've tested so far, but if you want something even larger, the U4919DW is the best super ultrawide alternative that we've tested so far.
The Dell S2417DG is the best Dell gaming monitor that we've tested so far. Although some may find the size of this monitor a bit small, it has a good number of features that most gamers look for. The TN panel provides an outstanding response time, a high 144Hz refresh rate, and has an optional black frame insertion feature to further reduce motion blur. Along with a low input lag and native support for NVIDIA's G-SYNC variable refresh rate technology, this monitor provides a smooth and responsive gaming experience that should please even the most hardcore gamers.
Unfortunately, TN panels have their disadvantages, as contrast ratio and black uniformity are rather poor, making this monitor less ideal for dark rooms. Viewing angles are also sub-par, which is disappointing for those who like to play co-op games. Additionally, out-of-the-box color accuracy is quite bad, but on the upside, the monitor's 1440p resolution provides a detailed picture, and the monitor's flicker-free backlight helps to reduce eye strain.
Overall, if you don't mind the smaller size, this is a great choice for those looking for a responsive monitor with exceptional motion handling.
If you find the Dell S2417DG too small, take a look at the Dell Alienware AW3418DW. This monitor also supports G-SYNC, but it has a 100Hz refresh rate and a 21:9 aspect ratio that provides an incredibly immersive gaming experience. Build quality is excellent and viewing angles are good, but like most IPS monitors, contrast ratio is mediocre and black uniformity is rather poor. This monitor is also a great choice for watching movies. As most modern movies are shot in the same aspect ratio, the picture fills up the entire screen, with no presence of black bars. Do note, though, that the extra screen real estate also means that there are more pixels, which will require a more powerful graphics card, especially if you want to achieve high frame rates.
If you want a higher refresh rate for a smoother gaming experience, go with the S2417DG, but for the best immersion, the AW3418DW/1900R is worth considering.
