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 Accurate colors
This monitor doesn't need to be calibrated because it is color-accurate right out-of-the-box. The monitor's average color inaccuracy measures at 1.83 dE - which is too low to be seen by a human eye.
Pro Has a speaker
The monitor comes with an external speaker that is mounted on the base of the S2418HN.
Pro Good picture quality
Regarding the picture quality, the Dell S2418HN performs on the par with the very best monitors in its price bracket thanks to its high-quality IPS panel. This monitor reproduces good-looking pictures that are filled with vivid colors and inky blacks.
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 Lacks adjustability
It's hard to get the perfect viewing angles on the S2418HN since it lacks some key ergonomic adjustments. You can't adjust the monitor's height or swivel angle.
