Our Verdict

ASUS ROG Swift PG348Q

Dell Alienware AW3418DW

The Dell Alienware AW3418DW is marginally better than the ASUS ROG PG348Q. The Alienware has a little faster refresh rate and produces a little less blur in fast-moving content. Also, the Alienware has lower input lag and responds slightly quicker to your actions giving you a small edge in gaming. Other than those minor differences, the two monitors are very similar.
