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.

Our Verdict

7.5 Mixed Usage

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. It does have poor black uniformity though with some backlight bleed, and a higher refresh rate would be an improvement for gaming.

  • Wide viewing angle
  • Uniform grays and colors
  • Good brightness
  • Blacks lack uniformity with some visible backlight bleed
  • Mediocre contrast
7.7 Office

Very good monitor for usage in an office. The 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 picture quality is also decent, and reflection handling is good.

7.9 Gaming

The monitor 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. It also doesn't support any more advanced features such as FreeSync or G-Sync.

7.3 Multimedia

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.

7.4 Media Creation

Better than average monitor for media creation. The monitor 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 monitor's standard narrow coverage.

5.5 HDR Gaming

HDR is not supported. There are only a few HDR compatible monitors at the moment, such as the Samsung CHG70.

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.

Native Contrast
1201 : 1
Contrast with local dimming

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.

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 Ultrasharp U2715H does great in our color bleed test and shows insignificant amounts of error. This means that large patches of color won't have distracting stripes extending across the display where they aren't supposed to appear.

Picture Quality

The reflection handling is good. The semi-gloss finish diffuses specular reflections across the screen, reducing their intensity. This is good for most environments, but may be an issue in a bright room.

Response Time Normal
Response Time Fast

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.

Power Supply Internal

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.

Additional Features
HDR10 No
Multiple input display

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-Screen Display (OSD)


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.
