Our Verdict
LG 27GN950-B
LG 27GP850-B/27GP83B-B
The LG 27GN950-B and the LG 27GP850-B/27GP83B-B are both great gaming monitors from the same lineup, with similar designs and gaming performances. The main difference is that the 27GN950-B is a 4k model with a 160Hz refresh rate, while the 27GP850-B is a 1440p model with a 180Hz refresh rate. In HDR, the 27GP850-B has a much wider color gamut, but the 27GN950-B gets a lot brighter to make highlights pop.
