Our Verdict
Dell Alienware AW2521HF
Samsung T55
The Dell Alienware AW2521HF is much better than the Samsung T55, mainly due to its 240Hz refresh rate. It has an exceptional response time, both at its max refresh rate and at 60Hz. The Dell also has wider viewing angles, a lower input lag, better ergonomics, and it gets brighter. On the other hand, the Samsung has a better contrast ratio because of its VA panel and it also displays a wider color gamut.
