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.

Con Bad for competitive gaming
The LG 34UC99-W isn't responsive enough for it to be used in competitive action gaming because of its high input lag and low native refresh rate.
