Our Verdict
LG 27UK650-W
LG 27GN950-B
The LG 27GN950-B is slightly better overall than the LG 27UK650-W, mainly due to the extra gaming features. The 27GN950-B has a max 144Hz refresh rate, gets brighter, has a much quicker response time, and has a lower input lag. However, the 27UK650-W delivers clearer text and has better reflection handling.
