Our Verdict
ASUS ROG Swift PG279Q
ASUS ROG Strix XG279Q
The ASUS ROG Strix XG279Q is better than the ASUS ROG Swift PG279Q. The XG279Q supports HDR, has a quicker response time, and its max refresh rate is slightly higher. However, the PG279Q has a much lower input lag at 60Hz, it has much better out-of-the-box color accuracy, and wider viewing angles.
