Our Verdict
LG 27GP950-B
LG 27GR95UM-B
The LG 27GP950-B and the LG 27GR95UM-B are both 4k gaming monitors in the LG UltraGear lineup, but there are a few differences. The 27GR95UM-B uses Mini LED backlighting, and even though its local dimming feature is better than on the 27GP950-B, it performs badly. One advantage of the 27GR95UM-B is that it gets much brighter, ideal for using it in a well-lit room.
