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 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 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 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.
