Alienware AW-Series AW2521H 24.5" Dark Side of the Moon 2021

The AW2521H is a 360Hz esports monster with exceptional motion clarity and G-Sync. It's in the 92nd percentile for performance, but the 1080p resolution and average HDR hold it back for anything else. Worth it if you're a competitive gamer, skip it if you want a do-it-all display.

This thing is fast. The 360Hz refresh rate over DisplayPort is the headline feature, and it delivers. Motion clarity is exceptional, and input lag is minimal, which is exactly what you want in a twitch shooter. G-Sync works seamlessly, eliminating screen tearing without adding noticeable latency. The 1ms response time keeps ghosting to a minimum. Colors are vivid and bright for an IPS panel, hitting 99% sRGB and 400 nits. But HDR10 is average at best, and there's minor backlight bleed in the corners. The NVIDIA Reflex Latency Analyzer is a nice bonus if you're into measuring click-to-action times.

Stacked against the ASUS ROG Strix XG27UCDMG or the MSI MAG 271QPX QD-OLED E2, the AW2521H looks dated. Those competitors offer 1440p or 4K resolutions with OLED panels and better HDR, but they also cost significantly more and don't hit 360Hz. The LG UltraGear 27GX790A-B is a closer match in refresh rate but with a larger 27-inch screen. If you want pure speed and don't care about resolution or HDR, the Alienware holds its own. If you want a monitor that does more than game, look elsewhere.

Pricing is all over the place. US listings range from USD 400 to USD 650, and that's a huge spread for the same monitor. At the low end, it's a solid deal for a 360Hz esports display. At the high end, you're paying a premium for the Alienware name and design. Best Buy has the better deal on the refurbished unit if you don't mind a scratch or two. For the money, you're getting top-tier motion performance, but the 1080p resolution and average HDR mean it's not a great value for anything other than competitive gaming.

The Alienware AW2521H is a 24.5-inch 1080p IPS panel built for one thing: competitive gaming. At 360Hz with a 1ms response time and G-Sync, it's aimed squarely at esports players who care more about frames than pixels. The design is pure Alienware, chunky and angular with RGB lighting, and it definitely makes a statement on your desk.

Our database puts its performance in the 92nd percentile, which is about as good as it gets for a monitor in this class. The social proof is strong too, with a 4.5-star average across 549 reviews. But it's not perfect. The display quality itself lands in the 39th percentile, and the thick back panel has annoyed more than a few buyers.

Skip this if you need a monitor for work, content creation, or mixed use. The 1080p resolution feels cramped for productivity, and the HDR is nothing special. If you want a monitor light bar, look elsewhere too, the thick back panel makes most of them impossible to mount. And if you're on a budget, the premium Alienware branding isn't worth the extra cash when cheaper 240Hz options get you 90% of the experience.

The Alienware AW2521H is a niche product, and it knows it. If you're a competitive FPS player who lives in games like Valorant, CS2, or Overwatch, this monitor is a fantastic choice. The 360Hz refresh rate and G-Sync make a real difference in fast-paced matches. But if you're a casual gamer, a content creator, or someone who wants a monitor for work and play, the 1080p resolution and average HDR will feel limiting. Buy it for speed, not for versatility.
