The Dell S2719DGF is a decent 144Hz monitor with a TN panel and mediocre picture quality. It has great gaming features such as support for FreeSync variable refresh rate technology, incredibly low input lag, and very fast response time. It can get bright enough to combat glare, but it has bad dark room performance due to the low native contrast ratio and terrible black uniformity. It has disappointing viewing angles and the image is accurate only when you're sitting directly in front of it. However, the excellent ergonomics allow you to place it how you like, and fortunately, it has good out-of-the-box color accuracy.

Our Verdict

7.2 Mixed Usage

The S2719DGF is a decent monitor for mixed usage. It has a very fast response time that leaves only minimal blur and a very low input lag to enhance the gaming experience. It has great size and resolution to allow you to multitask, and it can get bright enough to combat glare in most office environments. Unfortunately, it lacks good dark room performance with a low contrast ratio and terrible black uniformity.

Pros
  • Extremely fast response time.
  • Incredibly low input lag.
Cons
  • Bad dark room performance.
  • Image loses accuracy at an angle.
7.3 Office

The Dell S2719DGF is a decent monitor for office use. The screen size and native resolution are suitable for working with multiple windows open at the same time. It has excellent ergonomics and you can easily swivel it towards your coworker sitting next to you if you wish to share your work. It does a decent job at handling reflections, so you won't have to worry if a few small light sources are facing the monitor.

8.1 Gaming

The S2719DGF is a great monitor for gaming. It's very responsive to your actions due to the incredibly low input lag, and its extremely fast response time ensures that fast-moving content looks clear. It has a great resolution and large size for an immersive gaming experience, and it also supports FreeSync VRR to reduce screen tearing.

6.8 Multimedia

Decent monitor for multimedia. The S2719DGF is very responsive due to the low input lag, and it has great size and resolution so you can see every detail in your favorite videos. Unfortunately, the best image quality is reserved for those sitting directly in front of it due to the disappointing viewing angles.

7.0 Media Creation

The Dell S2719DGF is a decent monitor for media creation. It has a great resolution and size that allows you to open many windows on your screen. It has a great color gamut for casual users, but professionals might find it limiting. Unfortunately, the viewing angles are disappointing and you'll lose image accuracy when viewed from the side. On the upside, adjusting it how you like is easy due to the excellent ergonomics.

5.2 HDR Gaming

The Dell S2719DGF doesn't support HDR.

Design

The back of the monitor is very plain. All the inputs are in the back and are facing downwards so they won't protrude if you VESA-mount it.

Cable management is serviced through a hole on the stand, just like most other Dell monitors.

After calibration, its color accuracy is excellent. It's almost impossible to spot any inaccuracy with the naked eye. The color temperature is also extremely close to the 6500K target, and the gamma follows the target curve more closely, so most scenes will be at their correct brightness.

Excellent response time at 60Hz, which is great for people who want to use the S2719DGF for console gaming. When gaming at 60Hz, you might need to change the Overdrive setting compared to playing games at its max refresh rate. We recommend the 'Super Fast' setting, as motion looks the clearest, but the 'Normal' and 'Fast' settings perform similarly.
