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.

Weight (without stand) : 10.6lbs (4.8 kg)
Weight (with stand) : 15.0lbs (6.8 kg)

This UltraSharp 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.

Stand

Dell U2715H Build Quality picture

The build quality of this Dell monitor is good. Although it is almost entirely plastic, it still feels high quality and the design is well-refined.

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 of the U2715H make for an ordinary performance, especially if you are watching multimedia content with a lot of dark scenes. The U2715H 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 and even for gaming.

The Dell U2715H 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.

The overall gray uniformity of the 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 of the Dell U2715H monitor is poor and is in line with most IPS monitors we have tested, unfortunately. Flashlighting (backlight bleed) is visible near all corner, with the top left corner being the worst, as this BLB is even visible on our 5% gray test uniformity picture.

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 U2715H 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.

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 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.

Great response time, good enough for watching fast moving content. Only a short trail can be seen following our moving logo; most of the blur in the photo is due to 60 fps persistence. Smearing is unlikely to be an issue. 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 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 U2715H will forward the video for the other monitor out its DisplayPort Out.

There is an option to make the monitor chirp when the buttons are pressed, which provides feedback but can be annoying.

The Dell Ultrasharp U2715H is a good monitor for a mixed usage. It gets bright, has decent picture quality and no major flaws. It also comes with a factory calibration that makes it slightly more accurate than average.
Very good monitor for usage in an office. The U2715H's wide viewing angle, large working resolution, and great stand remove hassles around productivity and make it easy to share with co-workers on your sides.
The U2715H does well as a gaming monitor thanks to its low input lag and motion blur. However, its standard 60 Hz refresh rate and lack of black frame insertion feature make it less interesting for those interested in having the most fluid experience.
Decent monitor for consuming a variety of content. The U2517H's accurate colors and great grey uniformity give it a decent overall picture quality, and its better than average resolution allows for content to look sharp. Unfortunately, it doesn't support HDR and its contrast ratio and black uniformity leave a lot to be desired.
Better than average monitor for media creation. The Dell U2715H is sold with a decent factory calibration that makes its colors accurate out of the box. Our unit, however, had minor issues with its gamma tracking and color temperature, and those looking for support of wider gamuts won't be satisfied by the U2715H's standard narrow coverage.

I bought this monitor in Dec 2016 because it had such good reviews. I've been having severe ghosting with it especially when using Flux or Night Mode. Doing anything like dragging windows around or even scrolling text shows it very clearly where text leaves a trail behind. Have you experienced this? It's VERY bad and gives me a headache to use. I have a PB278Q hooked up and it does not show this problem at all.
Hi and thanks for contacting us. We did not notice 'severe' ghosting as you mention it, and we have maybe 8 or 9 or these monitors in our office. We did notice a faint red trail behind a gray moving object over a white background though, indicating that the response time of the red pixel may be a bit slower than the green and blue pixels. Also, we did notice that it was a bit worse when the 'Response Time' was set to 'Fast'. So in your case, if you were on the 'Fast' 'Response time' setting, it could be a good idea to try the 'Normal setting and see if it is better with this setting.
