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.
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 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.
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 bezels are very thin, which is great for multi-monitor setups.
The screen itself has a fairly thin profile, thinner than the Dell U2718Q. It shouldn't stick out much when VESA-mounted.
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.
As is the case with most IPS monitors, the contrast ratio is mediocre. This results in blacks looking like gray when viewed in a dark environment.
The Dell 2720Q doesn't have a local dimming feature. The video above is provided for reference only.
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.
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. There's some backlight bleed at the bottom edge of the screen and there's some blooming around the test cross.
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 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.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit even for the same model, due to manufacturing tolerances.
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.
There's a tiny amount of temporary retention, but it disappears quickly and shouldn't be an issue for most.
Outstanding gradient performance. There's still some banding when displaying dark greens and grays, though it shouldn't be noticeable in most regular content.
The monitor shows no signs of color bleed.
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.
Update 06/03/2020:We retested the text clarity, as it was taken with the incorrect scaling.
Text clarity is excellent, even without ClearType (bottom photo). The pixels are blurry due to the monitor's matte anti-reflective coating.
