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 Fights glare
This monitor works well even when placed in front of a window or a door since its peak brightness is high enough to fight the effect of glare. The sustained brightness of this monitor measures at around 350 nits.
Pro Works well in a bright room
When placed in a bright environment, the Dell U3417W offers excellent overall picture quality. There, the monitor displays vivid and eye-catching colors as well as some reasonably inky blacks. Additionally, the images look sharp thanks to the U3417W's high resolution of 3440x1440 pixels.
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 Poor performance in dark environment
When placed in a dark room, this monitor suffers from the backlight bleeding effect which is caused by the panel's inability to block out the backlight. This is a widespread issue for the IPS panels.
