The Dell S2721DGF is a 27 inch, 1440p monitor gaming monitor with a fast refresh rate and great gaming features. The IPS panel delivers wide viewing angles, and it has excellent ergonomics. It has a remarkable response time at the max refresh rate, with very little blur behind fast-moving objects, and it has a fantastic low input lag for responsive gaming and desktop experience. It's a versatile monitor with great reflection handling and a high peak brightness in SDR, so glare isn't an issue in a bright room. It has disappointing accuracy out of the box, but it has a superb SDR color gamut and incredible gradient handling. Although this monitor supports HDR and can display a wide color gamut, it can't get very bright in HDR and has low contrast, so HDR doesn't add much. 

Our Verdict

0.0
Mixed Usage 

The Dell S2721DGF is a great monitor for most uses. It has wide viewing angles, excellent ergonomics, and great reflection handling, making it a very good choice for office use or multimedia. Motion looks fantastic thanks to its remarkable response time at the max refresh rate, and it has low input lag, making it a great choice for gaming as well. Unfortunately, although it supports HDR, this doesn't add much due to the low peak brightness and low contrast.

Pros
  • Excellent gray uniformity.
  • Amazing horizontal viewing angle.
  • Low input lag.
Cons
  • Low contrast.
  • Terrible local dimming.
  • Disappointing accuracy out of the box.

Office 

The Dell 27 Gaming Monitor S2721DGF is a great office monitor. The 27 inch, 1440p screen is great for multitasking, and it has wide viewing angles and excellent ergonomics, so you can easily share your screen with someone else. It has great reflection handling and high peak brightness in SDR, so visibility isn't an issue in a bright room. Unfortunately, it has a low contrast ratio and poor black uniformity, so it's not ideal if you're in a dark room.

Pros
  • Excellent gray uniformity.
  • Superb SDR color gamut.
  • Amazing horizontal viewing angle.
  • Excellent ergonomics.
  • Great reflection handling.
Cons
  • Low contrast.

Gaming 

The Dell 27 Gaming Monitor S2721DGF is great for gaming. It has a remarkable response time at the max refresh rate, resulting in clear motion with almost no noticeable blur behind fast-moving objects, whether you're gaming on a high-end PC or a console. It also has low input lag for a responsive gaming experience. Finally, it supports AMD's FreeSync variable refresh rate technology, and it's certified to work with NVIDIA's G-SYNC Compatible mode, both of which help to reduce screen tearing.

Pros
  • Remarkable response time.
  • Fast refresh rate.
  • Low input lag.
  • Great reflection handling.
Cons
  • Low contrast.
  • Terrible local dimming.
  • Disappointing accuracy out of the box.

Media Consumption 

The Dell S2721DGF monitor is very good choice for watching videos. The amazing horizontal viewing angle makes it a great choice for watching the latest trending videos with some friends. The high SDR peak brightness and great reflection handling mean you don't have to worry about glare in a bright room. Sadly, it doesn't look as good in the dark due to its sub-par contrast ratio and poor black uniformity.

Pros
  • Excellent gray uniformity.
  • Amazing horizontal viewing angle.
  • Low input lag.
  • Great reflection handling.
Cons
  • Poor black uniformity.
  • Low contrast.
  • Terrible local dimming.
  • Disappointing accuracy out of the box.

Pros
  • Excellent gray uniformity.
  • Superb SDR color gamut.
  • Amazing horizontal viewing angle.
  • Excellent ergonomics.
  • Great reflection handling.
Cons
  • Poor black uniformity.

    Differences Between Sizes And Variants

    We tested the Dell 27 Gaming Monitor S2721DGF, which is the only size available. There's an S2721DGFA variant that's only available in Europe but appears to be the same monitor. There are other gaming options available from Dell's 'S' series of monitors, some of which are listed below.

    LG 27GP850-B/27GP83B-B

    Track

    The Dell S2721DGF and the LG 27GP850-B/27GP83B-B are very similar, each with strengths and weaknesses. The LG has an optional black frame insertion feature, which can help reduce the amount of persistence blur seen on-screen. The Dell has a more versatile stand, as it can swivel and switch to portrait orientation on either side, and it feels a bit better built than the LG.

    Samsung Odyssey G50D S27DG50

    Track

    The Dell S2721DGF and the Samsung Odyssey G50D S27DG50 are both budget-friendly 1440p gaming monitors. They have similar specs and features, although the Samsung has a slightly higher 180Hz refresh rate. The Samsung is also brighter and comes with more accurate colors, so it offers a more polished overall experience. That said, the Dell has four USB-A ports to which you can connect your devices, which you can't do with the Samsung.

    LG 27GL850-B/27GL83A-B

    Track

    The Dell S2721DGF is a bit better overall than the LG 27GL850-B/27GL83A-B. The Dell has much better ergonomics, better build quality, and better reflection handling. On the other hand, the LG is more accurate out of the box, and for the two units we tested, the LG has better black uniformity, but this varies between units.

    Dell S2719DGF

    Track

    The Dell S2721DGF is much better overall than the Dell S2719DGF. The S2721DGF has a faster refresh rate, and the IPS panel delivers much better viewing angles. The S2721DGF adds HDR support, but due to the low peak brightness and disappointing contrast, this doesn't add much.

    How We Test Monitors
    How We Test Monitors

    We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
