The Dell U2718Q is a very good 4k IPS monitor. Like most Dell monitors, it has outstanding ergonomics, so it's easy to adjust it to an ideal viewing position. It has decent accuracy out of the box and wide viewing angles, great for media creation or for sharing the screen with someone else. Areas of similar color look amazing, with no noticeable banding in gradients. Unfortunately, although it supports HDR, this doesn't add very much, as it can't display a wide color gamut and it has a low contrast ratio, so blacks look gray in a dark room.

Our Verdict

7.7 Mixed Usage

The Dell U2718Q is a good monitor for most uses. It has wide viewing angles and excellent ergonomics, great for use as an office monitor. It's a good basic gaming monitor, but it probably won't please most serious gamers. The high-resolution screen is also great for media creation or watching videos.

Pros
  • Wide viewing angles.
  • Easy to adjust stand with great ergonomics.
  • Outstanding gradient handling.
Cons
  • Poor HDR performance.
  • Mediocre black uniformity and visible backlight bleed.
8.1 Office

This is a great office monitor. The Dell U2718Q has wide viewing angles, excellent ergonomics, and a great amount of screen real estate. Text is exceptionally clear, and it has excellent uniformity. Although it can get bright enough for most viewing environments, it has mediocre reflection handling, so glare might be an issue in a bright room.

7.5 Gaming

Overall, the Dell U2718Q is a good gaming monitor, but it likely won't please serious gamers. It has low input lag and good response time, resulting in little blur behind fast-moving objects. Unfortunately, it's limited to a 60Hz refresh rate and it doesn't support any advanced gaming features.

7.7 Multimedia

The Dell U2718Q is a good monitor for multimedia. The high-resolution screen is great for watching the latest movies in 4k, and the wide viewing angles are great for watching the latest videos with a group of friends. Unfortunately, it has mediocre reflection handling, so glare might be an issue in a bright room.

8.0 Media Creation

The Dell U2718Q is a great monitor for media creation. The high-resolution screen allows you to see more of your work at once, and it has outstanding ergonomics and wide viewing angles. It also has excellent uniformity, decent accuracy out of the box, and outstanding gradient handling. Unfortunately, it has mediocre reflection handling, so glare might be an issue in a bright room.

6.6 HDR Gaming

Overall, the Dell U2718Q is a decent monitor for HDR gaming, thanks to the low input lag and good response time. Although this monitor technically supports HDR, there's little benefit to it, as it can't get very bright in HDR, can't display a wide color gamut, and it has a low contrast ratio.

Update 11/25/2020: We incorrectly listed the weight as 8.2 kg without the stand and 13.8 kg with the stand, when those values are the weight in pounds. The review has been updated.

The Dell U2718Q has a simple design, with very slim bezels on all four sides. The stand is simple, supports the monitor well with little wobble, and has excellent ergonomics.

The stand is very similar to the entire Dell lineup. It supports the monitor well, and despite the relatively large footprint, the base can still be used for other things as it's flat.

The back of the monitor is clean smooth, very similar to all other Dell monitors. There's a single hole in the bottom of the stand for cable management.

The borders are slim and blend well with the screen. This is ideal for multi-monitor setups as there'll be little gap between the monitors.

Build Quality

Like most Dell monitors, the U2718Q has good build quality. The stand adjustments flow well and don't need to be forced. The monitor is mostly made of plastic, but the parts fit well and there are very few gaps.

Mediocre HDR peak brightness. Real scene performance is slightly brighter than in SDR and the U2718Q performs well in most rooms. The brightness varied greatly during our testing, as the monitor appeared to boost the brightness of certain windows but then drop off the brightness after some time (see here). The posted results represent the most consistent results we could achieve (see here).

HDR is only supported when connected via HDMI.

If you want a monitor that has a higher HDR peak brightness, check out the Dell U2720Q, which is the successor of this monitor.

The Dell Ultrasharp U2718Q has excellent gray uniformity, with very little dirty screen effect, but the edges of the screen are noticeably darker than the rest. Sports fans shouldn't notice any issues when streaming games online, and there won't be any darker areas when browsing websites with large white areas.

Mediocre black uniformity, but better than most monitors we've tested. There's clouding across the entire screen, and the LED backlights bleed along the bottom edge, which can be distracting in a dark room.

This monitor has a very good response time, but there's more noticeable motion blur than high refresh rate gaming monitors. The 'Normal' overdrive setting produces the best results. If you want a faster response time, you can set the response time to 'Fast', but this introduces significant overshoot.

The Dell U2718Q only supports a 60Hz refresh rate, so these results are the same as the 'Response Time @ Max Refresh Rate' test.

There's a secondary flicker at 650Hz, but due to the secondary wave, the backlight doesn't completely shut off and the flicker isn't noticeable under most conditions.

Update 06/11/2020: There was a minor mistake in our scoring; it's been updated, but this has caused the refresh score to decrease a bit.

The Dell Ultrasharp U2718Q has a basic 60Hz refresh rate, which is common for 4k monitors. Most people won't have any issue with this, but gamers might be disappointed by the low refresh rate and lack of gaming-oriented features like FreeSync or G-SYNC.

If you want a monitor that supports VRR, check out the Dell S2721QS.
