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 Picture-in-picture mode easily displays two inputs at once
Because of the wide aspect ratio, LG offers a built-in picture-in-picture mode (referred to as Split Screen) to display two inputs at once.
Pro Looks great from every angle
The LG 29UM68 uses has great viewing angles, both vertically and horizontally. Color shifting (distortion of colors when viewed at a wide angle) doesn't occur.
Pro No noticeable backlight bleeding
The monitor doesn't allow any light of the backlight to get through, which results in no noticeable backlight bleeding: that means dark areas remain dark as intended.
Pro Good value for the money
The LG 29UM68 is relatively inexpensive compared to other 21:9 displays and is a great budget choice if you're specifically looking for an ultra-wide display.
Pro Aspect ratio is ideal for movies, offers greater field of view in games
The LG 29UM68 is a display with a rather unique 21:9 aspect ratio, which is ultra-wide. The difference with a regular 16:9 display is that there are added pixels on both sides, which increases workspace. It's also ideal to watch movies as most recent movies are filmed in a widescreen aspect ratio. Some games also offer support for 21:9 monitors and will allow you to have a greater field of view.
Pro Provides great image quality and color reproduction
The IPS-panel used in LG's monitor offers great image quality, especially compared to the more common TN-panels. Contrast is great with a 1000:1 ratio (better blacks), luminosity is excellent, images are vibrant and the color reproduction is great as well. These attributes are all due to the fact that an IPS panel was used.
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 Refresh rate limited to 75Hz, not great for fast-paced action
The maximum supported refresh rate of this monitor is 75 Hz or 75 frames per second which is a tad faster than non-Freesync monitors, but is not as good as 120 or 144 Hz displays. Especially fast-paced games benefit from a higher refresh rate, as it offers a more fluid gaming experience.
Con Slow response time
The response time for the screen is limited at 5 ms, which is significantly slower than some other monitors. This makes the LG 29UM68 less ideal for gaming situations that require quick input.
