The Dell UltraSharp U2720Q is a good 4k monitor that comes with HDR support and wide connectivity options. Like its predecessor, the Dell U2718Q, it features an IPS panel with good viewing angles, allowing you to easily share your work with colleagues. Images and text look sharp due to its high resolution, and its 27 inch screen provides plenty of space for multitasking. If you want to do some gaming on the side, it has a good response time and low input lag, however, there's no VRR support of any kind. On the bright side, its ergonomics are excellent and its USB-C input supports DisplayPort Alt Mode. 

Our Verdict

7.9 Mixed Usage

The Dell U2720Q is a good monitor for most uses. It's a great choice for any productivity task, as it provides enough screen real estate to have multiple windows opened simultaneously, and its 4k resolution makes text and images look incredibly sharp. Its input lag is low and response time is good, but it doesn't support any variable refresh rate technologies. It has impressive coverage of the Adobe RGB color space for content creators, although you may want to calibrate the monitor first, as its out-of-the-box color accuracy is only decent.

Pros
  • Excellent ergonomics.
  • Good viewing angles.
  • HDR support.
Cons
  • No VRR support.
8.3 Office

The Dell U2720Q is a great office monitor. Its 27 inch screen is great for multitasking and text looks sharp with its 4k resolution. You can easily adjust the screen to your optimal viewing position thanks to its excellent ergonomics, and it has an IPS panel that provides wide viewing angles, which is great when you need to share your work with coworkers. It should perform well in most rooms, although it's not recommended for very bright rooms with a lot of light shining directly on the screen, as its reflection handling is mediocre.

Pros
  • Excellent ergonomics.
  • Good viewing angles.
Cons
7.5 Gaming

The Dell U2720Q is a good monitor for gaming. It has low input lag and its response time is good, but its refresh rate is limited to 60Hz and it doesn't support any variable refresh rate technologies. It's not the most ideal for dark room gaming, as it has a low contrast ratio that makes blacks look grayish. On the upside, the monitor's 4k resolution and large screen size are great for atmospheric or RPG games, as it's able to bring out every little detail in your game for an immersive gaming experience.

Pros
  • Good viewing angles.
Cons
  • 60Hz refresh rate.
7.9 Multimedia

The Dell U2720Q is a good monitor for media consumption. It has an excellent resolution and screen size to provide great immersion, and its wide viewing angles let you share content with others. Gray uniformity is excellent, as there's very little dirty screen effect, but black uniformity is only passable and its IPS panel has a low contrast ratio, making it less suitable for dark room viewing.

Pros
  • Good viewing angles.
  • HDR support.
Cons
8.2 Media Creation

The Dell U2720Q is a great monitor for media creation. It has a large screen size and a high pixel density, resulting in sharp and detailed images. The IPS panel provides good viewing angles and its excellent ergonomics let you adjust the monitor however you like. It has great coverage of the Adobe RGB color space, but its out-of-the-box color accuracy is only decent, so calibration is highly recommended.

Pros
  • Excellent ergonomics.
  • Good viewing angles.
  • HDR support.
Cons
  • 60Hz refresh rate.
6.8 HDR Gaming

The Dell U2720Q is an okay monitor for gaming in HDR. The monitor can display a wide color gamut, however, its peak brightness is limited and its contrast ratio is low. It can provide a decent HDR experience in dark environments, but it won't look much different from SDR content in bright rooms.

Pros
  • Good viewing angles.
  • HDR support.
Cons
  • 60Hz refresh rate.

  1. Update 6/4/2020: We've retested the pre-calibration color accuracy, as we've discovered that the monitor has a dedicated sRGB mode. The score has been adjusted accordingly.
  2. Update 6/3/2020: We retested text clarity, as the scaling was set incorrectly. We also updated the input specifications, as we had incorrectly stated that the monitor supported Thunderbolt 3

The Dell U2720Q has a simple and professional-looking design that fits well in any office setting. The bezels are thin on all sides and the stand has a flat rectangular base.

Like most Dell monitors, the back is plain and there's a circular cutout on the stand that serves as cable management.

The build quality is good, even though it's entirely made of plastic. There are no obvious issues with the construction, and while the stand feels a bit flimsy, it supports the monitor well.

Decent HDR peak brightness. The brightness is much more consistent than what we had observed on the U2718Q, but there's a noticeable drop in the 2% windows that's likely due to brightness compensation.

06/04/2020: We've retested the pre-calibration color accuracy, as we've discovered that the monitor has a dedicated sRGB mode that's significantly more accurate. The measurements have been updated and the score has been adjusted accordingly.

Before calibration, the U2720Q's color accuracy is decent. Most colors and white balance are slightly inaccurate, and the color temperature is warmer than our 6500K target, resulting in a slight reddish tint. Gamma doesn't follow the target curve at all, with most scenes appearing darker than they should.

After calibration, color accuracy is outstanding. White balance, gamma, and color temperature are nearly perfect. There's still some inaccuracy with the color blue, which is typical for LED monitors.

The U2720Q has a good response time, although there's still a bit more motion blur than gaming monitors. We recommend using the 'Normal' overdrive setting, as it has the least amount of overshoot. If you prefer a monitor with a much quicker response time but a lower resolution, check out the Dell UltraSharp U2520D.
