Our Verdict

Dell Alienware AW2521H

Dell Alienware AW2523HF

The Dell Alienware AW2523HF and the Dell Alienware AW2521H are both great 360Hz gaming monitors with a few differences. The AW2521H has native G-SYNC support, while the AW2523HF has native FreeSync support. It gives you a few extra features if you have an NVIDIA graphics card, like NVIDIA's Reflex Latency Analyzer to measure the latency of your entire setup, and the FreeSync support on the AW2523HF is beneficial if you have an AMD graphics card. On the other hand, the AW2523HF is better for console gaming because it has a Console Mode that downscales 4k images, which the AW2521H doesn't have.
