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.
We buy and test more than 30 monitors each year, with units that we buy completely on our own, without any 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 and custom tools to measure various aspects with objective data-based results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance against the competition, and whether or not it's easy to find.

Test Results
The Dell UltraSharp 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.
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.
Ergonomics are excellent. The stand allows for all manner of adjustments and the screen can rotate to portrait mode in either direction. If you need a wider swivel range to share work or content, check out the ASUS ProArt Display PA278QV. Like most Dell monitors, the back is plain and there's a circular cutout on the stand that serves as cable management.
The stand has a flat rectangular base and although it has been shrunken down a bit compared to the Dell U2718Q, it still supports the monitor well and there's very little wobble.
The monitor's controls are located at the bottom right corner of the screen. There's a power button as well as four other buttons to navigate the on-screen menu.

As is the case with most IPS monitors, the contrast ratio is disappointing. This results in blacks looking like gray when viewed in a dark environment. It has a local dimming feature that automatically turns on with HDR signals, and there's no way to disable it. Sadly, it worsens the contrast because all the dimming zones are on with our test pattern.
The Dell U2702Q has an edge-lit local dimming feature that automatically turns on with HDR signals, and there's no setting to disable or enable it. It has about 10 big zones, and an entire zone turns on where there's a small highlight, which could become distracting. However, most content triggers all the zones to turn on, and the local dimming isn't do anything. It's disappointing that you can't disable the local dimming in HDR because it performs terribly.
Good SDR peak brightness. It performs best in dark to moderately-lit rooms, as it can't get bright enough to overcome glare in very bright rooms. If you want something even brighter, then look into the Dell S2722QC.
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.
The Dell U2720Q has good horizontal viewing angles, which is great for sharing content or work with others.
Great vertical viewing angles. The image should remain accurate even if you sit up close, with only a slight loss of brightness and color at the top and bottom of the screen.
Excellent gray uniformity. The sides of the screen appear darker, but thankfully, there's very little dirty screen effect.
Black uniformity is passable without the local dimming feature enabled. There's some backlight bleed at the bottom edge of the screen, and there's some blooming around the test cross. Sadly, the local dimming makes the uniformity worse because there's more blooming around the center cross.
Before calibration, the Dell 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.
Outstanding SDR color gamut. The monitor has full coverage of the sRGB color space used in most content, and it has great coverage of the Adobe RGB color space, which is mostly used by professionals such as photo and video editors.
Outstanding SDR color volume, but it can't display dark and saturated colors well due to its low contrast ratio.
The Dell U2720Q has a decent HDR color gamut. It has great coverage of the commonly used DCI P3 color space, but coverage of the wider Rec. 2020 is just okay.
Decent color volume. It's mostly limited by its HDR color gamut and low contrast ratio.
The Dell U2720Q has mediocre reflection handling. It should be fine in dark to moderately-lit rooms, but it's best to avoid having bright light shining directly on the screen.
Text clarity is excellent, even without ClearType (bottom photo). The pixels are blurry due to the monitor's matte anti-reflective coating.
Outstanding gradient performance. There's still some banding when displaying dark greens and grays, though it shouldn't be noticeable in most regular content.
Unfortunately, the Dell U2720Q has a basic 60Hz refresh rate and doesn't support any type of variable refresh rate technologies. If you want a similar monitor that supports VRR, check out the Dell S2721QS.

The Dell 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.
The Dell U2720Q doesn't have an optional backlight strobing feature.
The monitor has a flicker-free backlight that can help reduce eye-strain.
The Dell U2720Q has an excellent low input lag, and it remains low even in 10-bit HDR.
The monitor's 27 inch screen and 4k resolution are excellent for a wide range of uses. It provides enough space to have multiple windows opened at the same time and the high pixel density is great for text clarity.
Update 06/03/2020: We incorrectly listed this monitor as supporting Thunderbolt 3. It doesn't.
The Dell U2720Q has two USB-C ports, which support DisplayPort Alt mode as well as power delivery of up to 90W. One of the USB-C port can be used for charging even when the monitor is off.
This monitor works well with recent MacBook Pros. Windows return to their original position when you wake your computer from sleep, and power delivery over USB-C works great. HDR works properly. The default scaling is set to 1080p, but you can easily adjust this from the macOS Display settings.
