Our Verdict
AOC 24G2
Dell Alienware AW2521HF
The AOC 24G2 and the Dell Alienware AW2521HF are both 1080p gaming monitors, although the Dell has a slightly bigger 25" screen versus the AOC's 24". The Dell delivers a better gaming experience because it has a much higher refresh rate of 240Hz and faster response times. It also has wider viewing angles for sharing content, a USB hub with four USB 3.0 inputs, and it gets brighter to fight glare.
