Our Verdict
Dell U2717D
ASUS ROG Swift PG279Q
The ASUS ROG PG279Q is much better than the Dell U2717D. The ASUS performs much better in gaming, as it has a lower input lag, a much faster refresh rate, supports G-SYNC VRR, and has less motion blur. Finally, the ASUS offers the option to introduce flicker to make the image crisper.
