Pros
Pro Great for competitive gaming
The BenQ RL2455 is responsive enough to be used in competitive gaming thanks to its low input lag, high native refresh rate, and excellent motion tracking. This is one of the cheapest monitors aimed towards the community of competitive action gamers.
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.
Cons
Con Sub-par picture quality
In this price range, there are numerous monitors that offer substantially better picture quality than the RL2455.
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.
