Our Verdict

LG 38GN950-B

LG 34GP950G-B

The LG 38GN950-B and the LG 34GP950G-B are very similar overall. The 38GN950-B has a larger, higher resolution screen which some people might prefer. The 34GP950G-B might be better for gamers with an NVIDIA card, as it has native support for G-SYNC, so it supports a few extra features, including variable overdrive.
