Pros
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.
Pro Excellent viewing angles
The monitor's overall picture quality doesn't degrade much if you view the panel at an angle. This is especially important for those who, for example, plan to mount the monitor on a wall.
Pro Works good in a well-lit room
When situated in a bright room, regarding picture quality the Dell U2718Q performs on par with the best monitors in its price bracket. It delivers beautiful images that have lifelike colors and deep blacks. Colors look fantastic thanks to the monitor's IPS panel that can sustain the reasonably high level of brightness - up to 300 nits, without losing the details.
Cons
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.
Con Poor HDR performance
This monitor can't deliver the proper playback of the HDR content because its peak brightness and color gamut don't correspond to the HDR requirements. The U2728Q covers only around 75% of the DCI-P3 which means that it can reproduce only 3/4 of the total colors used in the HDR content.
