Our Verdict
LG 27GN950-B
ASUS ROG Strix XG27AQ
The LG 27GN950-B and the ASUS ROG Strix XG27AQ are both impressive gaming monitors with different resolutions. The ASUS is a 1440p monitor, while the LG is a 4k monitor that delivers a sharper image. The LG also has a slightly faster response time, delivering exceptionally smooth motion, although its refresh rate maxes out at 160Hz whereas the ASUS can reach 170Hz. Both have VRR support and low input lag. While the LG has a slight edge when it comes to performance, the ASUS feels better built and has better ergonomics and reflection handling, if these are important to you.
