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 Has a curve
You might experience the effect of immersion while working with the U3818DW thanks to its massive size and curvature which, combined, make up that feeling of extra immersion.
Pro Good for multitasking
This option is ideal for the fans of multi-tasking since its massive, 38-inch 3840x1600 pixel panel can seamlessly fit three Word documents stacked side by side. That's a lot of space for a single monitor.
Pro Excellent picture quality in well-lit enviromnent
Placed in a bright room, the Dell U3818DW offers exceptional overall picture quality thanks to its ability to reproduce accurate and vivid colors as well as some reasonably inky shadows. Colors look crisp and lifelike because of the monitor's high-quality IPS panel that genuinely bright without losing the color accuracy.
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 Bad for action gaming
The Dell U3818DW is not the best pick for action gaming because of its low responsiveness. The action gaming feels laggy because of the monitor's high input lag and low native refresh rate.
