Our Verdict
ASUS ROG Swift PG279QM
LG 27GP850-B/27GP83B-B
The ASUS ROG Swift PG279QM and the LG 27GP850-B/27GP83B-B deliver very similar performance, each with strengths and weaknesses. The ASUS has better ergonomics, so it's easier to place it in an ideal viewing position. On the other hand, the LG has a faster response time at the max refresh rate, and it has an optional backlight strobing feature to improve the appearance of motion.
