Our Verdict
ASUS ROG Swift PG279QM
Dell Alienware AW2723DF
The Dell Alienware AW2723DF and the ASUS ROG Swift PG279QM are both 1440p, 240Hz gaming monitors with a few differences. The Dell has an overclockable refresh rate of up to 280Hz, which the ASUS doesn't have, and it also has a lower input lag. The main difference between the two is that the ASUS has native G-SYNC support, which lets you take full advantage of your NVIDIA graphics card, as you can also use its Reflex Latency Analyzer feature to measure the input lag of your entire setup.
