Our Verdict

LG 27GP950-B

Samsung Odyssey G7 S28AG70

The LG 27GP950-B and the Samsung Odyssey G7 S28AG70 are both high-end 4k gaming monitors. They have many of the same features with HDMI 2.1 inputs, and even though their native refresh rates are both 144Hz, the LG is overclockable to 160Hz. The LG also has better motion handling at 60Hz, and it gets much brighter, especially in HDR. The HDMI 2.1 inputs on the LG support a higher 48 Gbps bandwidth compared to 40 Gbps from the Samsung, but it doesn't make a difference unless you need to achieve 4k @ 120Hz signals with 12-bit color depth. On the other hand, the Samsung has better ergonomics because you can swivel it.
