Our Verdict
ASUS TUF Gaming VG34VQL1B
Dell S3422DWG
The ASUS TUF Gaming VG34VQL1B is slightly better than the Dell S3422DWG overall, but the Dell might still be better for some people. The ASUS has better contrast and a slightly faster refresh rate, as well as slightly better ergonomics. The Dell, on the other hand, has much better black uniformity and a faster response time at 60Hz.
