Our Verdict
Dell Alienware AW2521HF
BenQ ZOWIE XL2546K
The Dell Alienware AW2521HF and the BenQ ZOWIE XL2546K are both 25 inch, 1080p, 240Hz gaming monitors but with different panel types. The Dell uses an IPS panel, while the BenQ has a TN panel. Motion handling is about the same, but the Dell has slightly better response times. It also has wider viewing angles, and it gets brighter to combat glare. The BenQ has a Black Frame Insertion feature, but it isn't usable simultaneously with VRR, and the flickering might bother some people.
