Our Verdict
LG 27GN850-B/27GN880-B
MSI Optix MAG274QRF-QD
The MSI Optix MAG274QRF-QD is a bit better for most uses than the LG 27GN850-B/27GN880-B, but they have many of the same features. They both have outstanding response time and low input lag for gaming, but the MSI has a slightly higher 165Hz refresh rate. It also has a BFI feature, but it only works within a narrow range. However, the LG has better out-of-the-box accuracy, and colors don't look as over-saturated as the MSI, so you may not need to get it calibrated to enjoy it to the fullest.
