Ranked in these QuestionsQuestion Ranking
Pros
Pro Great viewing angles
As expected from an IPS panel, viewing angles are great. Horizontal adjustments don't change the colors much at all. When tilting in the vertical axis, the image can darken slightly.
Pro Lots of ports
With 5 USB 3.0 ports (one of which can act as a charger), 2 HDMI ports (with MHL), a DisplayPort and Mini DisplayPort, as well as a DisplayPort out port for daisy chaining multiple screens
Pro Fully adjustable
It has tilt, swivel, height adjust and can be pivoted 90 degrees in both directions.
Pro Great for multi-monitor setups
The thin plastic bezel (1mm) and small 6mm screen boarder makes this a great screen to put side by side with another to minimise the deadspace between dual monitor setups. Also, an extra DisplayPort out means daisy chaining is possible.
Pro Fantastic screen quality
Dell calibrates the U2715H's screen in the factory to very precise measurements, and each monitor will have their own unique calibration report.
Pro Cover all of sRGB color gamut
The monitor covers all of sRGB space and with some calibration is capable of representing the colors accurately.
Pro Good contrast
Pro Smooth surface
Among the least grainy matte surfaces available for UHD monitors.
Pro Low input lag
Complete input lag time (signal delay and pixel response time) is 6.85ms or under ½ of a frame.
Pro Can automatically shut down when you're away
The monitor has a proximity sensor that allows it to be automatically set to standby mode once you're away from the monitor for more than 40 seconds.
Pro Can auto-adjust brightness throughout the day
Can be set to automatically adjust brightness due to the built in ambient light sensor.
Cons
Con Buttons can be unresponsive
The captive buttons on the right side of the bottom bezel don't light up at all, and can be unresponsive when you first try to activate them.
Con Poor panel uniformity
While this will vary unit to unit, TFT Central found that the luminance uniformity on their unit was poor. The right side of the screen was up to 30% brighter than the left corners of the screen. It wasn't obvious at first glance, however for color-accurate work it could become an issue.
Con A maximum refresh rate of 60Hz can be a concern for some
A 60Hz monitor, while sufficient for most people in most cases, can still cause issues with fast-moving objects on screen. It's especially important with things like gaming where the ability to react to events happening on the screen quickly is important.
Con AHVA glow
AHVA glow is the light on the sides or corners of the screen that can reduce some of the peripheral detail.
Con Poor dynamic contrast implementation
Dynamic Contrast is an optional feature meant to increase or decrease the back-lighting depending on scene that is displayed in order to get higher dynamic range. Unfortunately, the implementation tends to slightly overshoot on highs regardless of the settings used.
Con Some color temperature uniformity issues
According to Spyder5Elite tests performed by PC Monitor, BL2711U has color temperature issues that can be seen with the naked. A DeltaE deviation of over 3 can be easily noticed and there are deviation of up to 3.8.
