Pros
Pro Excellent for fast-paced gaming
Regarding its gaming capabilities, the performs on par with the best monitors available in this price range, as its 27-inch QHD panel offers smooth and lag-free gaming experience even in the fastest games.
The ASUS MG279Q feels as responsive thanks to its small input lag, that is measured at only 4.05 ms, which means that the monitor needs a tiny bit more than four milliseconds to process a frame generated by your computer.
Its 165 Hz panel displays motion flawlessly, without even the tiniest trace of motion blur or ghosting present.
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 Not good for dark rooms
You can observe some minor traces of IPS glow when the monitor is placed in a dark room. Such events occur when the panel can't absorb the 100% of light emitted by the backlight diodes.
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.
