Dell U2718Q Monitor Review

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.

Like most Dells, this monitor has outstanding ergonomics, making it very easy to place it in the ideal viewing position.

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.

The back of the monitor is of fairly uniform thickness and doesn't stick out much when VESA-mounted.

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.

Like most IPS monitors, the contrast ratio is low, resulting in blacks that look gray in a dark room.

This monitor doesn't support local dimming. The video is provided for reference only.

Good peak brightness levels with negligible variation depending on content. The monitor is bright enough for most rooms, but it can't overcome direct glare.

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 U2718Q has very good horizontal viewing angles. This makes it a great choice if you often share the screen with someone else, or if you like to sit close.

Decent vertical viewing angles. Someone looking at the monitor from above might notice a slight decrease in brightness but shouldn't notice much else.

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.

Decent out-of-the-box accuracy. The white balance is off a bit, causing some noticeable inaccuracies in brighter shades of gray. Most colors are displayed accurately, and gamma almost follows the sRGB target curve, but some scenes are darker than they should be.

After calibration, the Dell Ultrasharp U2718Q has outstanding accuracy. Any remaining inaccuracies aren't noticeable, and gamma follows the sRGB color space almost perfectly.

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.

Excellent coverage of the standard sRGB color space. Limited coverage of the wider Adobe RGB color space, which may be disappointing to professional users for editing graphics or print media.

The Dell Ultrasharp U2718Q has excellent color volume in SDR. Adobe RGB coverage is limited by the poor color space coverage and isn't as good as other HDR monitors we've tested, like the Samsung CHG70.

Decent HDR color gamut, but it can't display a wide color gamut. Note that HDR is only supported over HDMI on this monitor.

Unfortunately, the Dell U2718Q has poor color volume in HDR. It's severely limited by the color gamut, and it can't produce dark saturated colors very well. Note that HDR is only supported over HDMI on this monitor.

There are no signs of temporary image retention.

The Dell U2718Q reproduces gradients perfectly, with absolutely no banding.

This monitor is free of color bleed. This is great for graphics artists that use large areas of uniform color.

Unfortunately, the Dell U2718Q has mediocre reflection handling. Reflections aren't diffused as much as the U2717D and they may be distracting.

Text is exceptionally clear on this monitor. It isn't necessary to enable ClearType, but if you do, text is extremely sharp.

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. 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 uses a dual PWM flicker to dim the backlight. There's a 10kHz flicker that's always present, but this flicker is not visible at all. 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.

There's no optional black frame insertion feature on this model.

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.

The Dell Ultrasharp U2718Q has excellent input lag, great for office use or even for most gamers.

This monitor has a very sharp 4k UHD resolution, which is excellent for almost any use.
