Our Verdict
ASUS TUF VG27AQ
Dell S2721DGF
The ASUS TUF VG27AQ is slightly better than the Dell S2721DGF overall, but the Dell might be a better choice. The ASUS has better vertical viewing angles, and the unit we tested has better black uniformity, but this varies. On the other hand, the Dell has a faster response time, resulting in clearer motion.
