Our Verdict
ViewSonic Elite XG270
Dell Alienware AW2521HF
The Dell Alienware AW2521HF and the ViewSonic Elite XG270 have a lot in common, as both monitors feature a 1080p IPS panel with a 240Hz refresh rate. The main difference is that the ViewSonic supports HDR, has a black frame insertion feature that can help improve motion clarity, and it has a bigger 27 inch screen. However, the Dell has a better build quality, a significantly better black uniformity, and its response time is faster, resulting in less motion blur.
