Our Verdict
LG 27UD58-B
HP 27Q
The LG 27UD58-B is somewhat better than the HP 27Q. The LG 27UD58-B has a better input lag and is more responsive to your actions. It also has better resolution allowing you to display more in the same screen size. On the other hand, the HP 27Q is brighter and can handle reflections better, so it's more suitable for a slightly brighter room with many light sources.
