Our Verdict
LG 27GP950-B
Gigabyte M27U
The LG 27GP950-B and the Gigabyte M27U are both 4k, 27-inch gaming monitors. They offer similar performance overall, but the LG has a better HDR color volume and gets brighter in HDR for a slightly improved HDR experience. The LG also supports the full 48 Gbps bandwidth of HDMI 2.1, so your graphics card doesn't need to use compression. However, the Gigabyte has extra productivity features like a KVM switch and USB-C port.
