Pros
Pro Decent black levels, good contrast ratio
The black levels are respectively low at 0.16cd/m², which helps the contrast ratio achieve 1100:1 which is much lower than the advertised 5000:1, but still quite good.
Pro Pretty fast response times make the system feel quick
The response time is 12ms, which isn't lightning fast, but it's still quick enough to make the system feel more responsive than cheaper monitors. While not fast enough for high-level gaming, this monitor won't make your system feel slow or unresponsive.
Pro 'Massive tablet' design is unique, and versitile
It really does look like a massive tablet with a kickstand - but that's not a bad thing. There's no stand visible, leaving the front looking very clean. The stand can angle anywhere from 15-70 degrees which allows for flexible use, or it can be folded in and used flat on the desk or even mounted using the VESA mounting holes.
Pro Built-in speakers, webcam, and mic
This monitor has many peripherals built-in, and unless you use them heavily they will do the job just fine. Unless you feel the need for dedicated hardware, the built-in stereo speakers work well enough, and the webcam and mic are acceptable quality for occasional recreational use (for business calls or other uses where quality is important, you'll want to upgrade to dedicated hardware).
Pro Possible to adjust the display to your preference
You can work with the monitor in the position that’s most comfortable for you. This display is very adjustable, you can not only adjust both the height and inclination, but also it’s angle (you can use it horizontally or vertically).
Pro Amazing image quality for professional work
The Dell P2715Q provides excellent image quality, especially for its price tag. It's a good tool for tasks that involve visual content, such as photography or film edition, graphical design work or illustration. It’s capable of displaying lively and very accurate colors, high brightness levels and deep blacks. Its vision angles are quite good and it has good screen uniformity.
Cons
Con Disappointing color accuracy
The MVA panel (multi-domain vertical alignment: in-between of TN and IPS technologies) doesn't reproduce colors very accurately. It scores just 82% of the sRGB color gamut, while other panels offer high 80s and even above 90%. This display's weakest points are with the green and cyan shades, while reds and blues appeared just fine.
Con Dim display
The display doesn't get very bright - at just 172cd/m² this panel is very dim. Many monitors can achieve 300cd/m² or higher brightnesses.
Con Takes much more power than similar monitors
Without using the ECO mode, this monitor requires about 50 watts to power it. This is double than other monitors. There are different levels of ECO modes, however these dim the display and barely get down to the power level of other monitors when they are all enabled.
Con Not very good for gaming
The Dell P2715Q is not ideal for gaming, given that is has a response time of 9mm and a refresh rate of 60 Hz. These means, for example, that its not perfect when dealing with fast-moving scenes.
