The Dell Ultrasharp U2715H is a good IPS LCD monitor with wide viewing angles and a 1440p resolution that make it very suitable for productivity-oriented environments. Its flexible and easy to use stand makes setting up and sharing your screen a bliss, and its colors are quite accurate thanks to a factory calibration. Unfortunately, its blacks aren't the most uniform and show signs of glow, and it doesn't offer higher refresh rates for better motion.
This Dell Ultrasharp U2715H monitor has the familiar Dell aesthetics, which is great. The stand has a small footprint but still feels stable and supports the monitor well, with ergonomic options to tilt, swivel and adjust the height easily. It also has a quick-release VESA mount which makes it simple to attach to another stand or move easily. The rear of the monitor is also simple,but looks professional. As with other Dell monitors, the build quality is good.
This Dell U2715 monitor has a wide range of ergonomic adjustments, making it easy to adapt to any setup or space. The height adjustment range is good, and the monitor can easily be rotated to portrait.
The Dell U2715H IPS monitors have an average picture quality. When set in a dark room, the below average contrast ratio and the poor black uniformity make for an ordinary performance, especially if you are watching multimedia content with a lot of dark scenes.
The monitor does much better when used in a brighter environment like an office space, as it has a great SDR peak brightness and good reflection handling which help fight glare from a close lamp or even a bright window. Color accuracy is good out of the box and remains good even when viewing the monitor at a sharp angle. The monitor is pretty simple though and does not have more advanced features like HDR and local dimming, but overall is still a very good option for office work (see our recommendations for the best work monitors) and even for gaming.
The monitor has a below average contrast ratio but is rather good for an IPS monitor, which always have a much lower contrast ratio than VA panel monitor or TV. The negative effect of a low contrast ratio will show up when the monitor is used in a dark environment, as blacks will look more gray than really black. Fortunately, if the monitor is used in a well-lit environment, like an office space, this negative effect is noticeable, as the ambient enhances perceived black level.
Great SDR peak brightness. The Dell U2715H gets bright enough to accommodate for even more challenging environments. It does not change brightness over time or with different content shown on screen.
HDR is not supported.
Good horizontal viewing angle. Thanks to its use of an IPS panel type, the monitor maintains its black level even from very steep angles. Colors also remain accurate enough for the monitor to be easily shared with people to the sides.
Decent vertical viewing angle for the Dell Ultrasharp U2715H. Colors and brightness are retained relatively well at an angle. Blacks, however, shift significantly more vertically than horizontally, causing part of the uniformity issues seen in the black uniformity test (IPS Glow).
The overall gray uniformity of the Dell U2715H monitor is impressive. Looking at the 50% gray test uniformity picture, we can see a faint darker horizontal line near the center of the screen, but luckily it did not show up too much while looking at normal content. The rest of the uniformity issues (darker corners and brighter top edge) are almost all located on the edge of the panel itself, and thus dirty screen effect is not a problem here.
Looking at our 5% gray, the only visible problem that we can notice is the upper left corner that is a bit brighter than the rest of the screen, and this is also the same spot that has some flashlighting visible on our black uniformity test.
The black uniformity is poor. Unfortunately, this is in line with most IPS monitors we have tested. Flashlighting (backlight bleed) is visible near all corners, with the top left corner being the worst. This is visible as blotchy dark images when viewed in a dark room.
Out of the box, the accuracy of the Dell U2725H monitor is better than average when set on the most accurate picture mode, which was the 'Custom Color' picture mode.
The color temperature was a bit warmer than our desired 6500K color temperature and this is reflected in our white balance reading, as the monitor is missing a lot of blue in the lighter grayscale shade. The White balance dE is still pretty reasonable though at 2.71, which is under the level of inaccuracy that most enthusiasts would notice. As for the gamma, the overall value is not far from our 2.2 target, but the curve does go off target in the darker shade of gray.
The color accuracy of the monitor, which a dE of 3.48, is a bit off, as it would be noticeable to an enthusiast. Not color in particular are really problematic though.
After calibration, which was also done on the 'Custom Color' mode, as it is in this mode that we have the full control on the internal RGB cuts/gains controls, the accuracy of the Dell U2715 is excellent.
The color temperature is much closer to our desired 6500K, and both the color dE and the white balance dE are well under what anybody, even professional could notice. The gamma is a bit closer to our 2.2 target, and the curve track more closely our target curve, where the big derivations are now corrected.

Excellent coverage of the s.RGB (rec. 709) color gamut. The Dell U2715H's better than average factory calibration allows it to track the s.RGB color space very accurately giving it an almost perfect reproduction. Unfortunately, it does not actively support the professionally oriented Adobe RGB color space, making it less useful for applications that require it.
Excellent SDR color volume. The Dell U2715H's relatively accurate out of the box color mapping means it has no issues covering the s.RGB color volume. It only sees issues in darker tones due to its relatively low contrast ratio. Its coverage of Adobe RGB is passable, but not suitable for more professional users that require that color space.
The Dell U2715H has a great performance when displaying our gradient test image. The 8-bit banding is visible, but besides it, not many issues can be noticed. Some little issues are visible in the darker shade of color, but banding it not problematic white watching normal content.
Motion looks decent on the Dell Ultrasharp U2715H, but not as good as on many gaming monitors. While the monitor has great pixel response time and a flicker-free backlight, its fixed 60 Hz refresh rate is fairly limiting for serious gaming.
Great response time, good enough for watching fast moving content such as playing video games. Only a short trail can be seen following our moving logo; most of the blur in the photo is due to persistence as an object is followed past a static frame. Smearing is unlikely to be an issue, which is great. The 'Response Time Fast' setting is a little faster than the default 'Normal' but introduces visible overshoot. However, some people who are not bothered by overshoot may prefer it.
The backlight is dimmed without using any PWM flickering, which is great and produces smooth motion. Unfortunately, there is no option to add flicker using black frame insertion, which would reduce blur further. This isn't that bad though, as many people find 60Hz flicker distracting.
This is a simple 60 Hz monitor without any higher refresh rates or variable refresh rate options. This is fine for most use cases, but for gaming, this limited refresh rate will be a hindrance.
The Dell Ultrasharp U2715H has a very good QHD resolution and fairly large 27" size, which are great for most usages. It also has great low input lag, which will please all but the most competitive gamers.
Great low input lag for the Dell Ultrasharp U2715H, which should please all but the most competitive gamers. The input lag is constant no matter the input resolution, which is handy when gaming at lower resolutions like 1080p.
The Dell Ultrasharp U2715H has a DisplayPort Out for daisy chaining with another monitor, so both monitors can be fed using only one DisplayPort out from the computer.
The Dell Ultrasharp U2715H has all the standard features of a monitor such as adjustable overdrive, image and color settings, all arranged in a well laid out on-screen display menu. It also has a DisplayPort Out so it can be used to drive a second monitor through daisy chaining.
The monitor has a DisplayPort Out for daisy chaining displays, so two monitors can be fed from one DisplayPort on the computer. This means that when another monitor is connected to the U2715H, the computer will send video output for both monitors to the U2715H, and the monitor will forward the video for the other monitor out its DisplayPort Out.
On the lower right corner of the monitor, there is one power button and four multifunction buttons for navigating the OSD. The buttons are activated by a light touch and have no click feedback, which can take some getting used to. There is an option to make the monitor chirp when the buttons are pressed, which provides feedback but can be annoying.
We tested the U2715H, which is a 2015 model 27" Ultrasharp monitor. There are many other sizes and year variants of the Dell Ultrasharp monitors, listed below.
