Our Verdict

Dell Alienware AW2721D

Samsung Odyssey G7 S28AG70

The Dell Alienware AW2721D and the Samsung Odyssey G5 S27AG50 are different types of gaming monitors. The Dell is meant for high-frame-rate gaming because it has a 240Hz refresh rate with a 1440p resolution, and it has native G-SYNC VRR support. The Dell has a faster response time, but there's also more overshoot, and motion handling is fantastic between each. The Samsung is meant for high-resolution gaming because it has a 4k resolution with FreeSync support and HDMI 2.1 inputs, making it a good choice for console gaming. The Dell gets brighter, but the Samsung has better reflection handling. Also, while they each have local dimming features, they both perform terribly.
