This article covers Alienware 25 AW2521HF 24.5 inch Gaming Monitor (Dark).
Overview
The Alienware 25 AW2521HF is a 24.5-inch Full HD gaming monitor from Dell's premium Alienware brand. Its standout features are a 240Hz refresh rate and 1ms GtG response time, delivering exceptionally smooth motion clarity for fast-paced competitive shooters and racing games. The Fast IPS panel technology ensures wide viewing angles and solid color reproduction, with a claimed 99% sRGB coverage that makes it usable for light creative work as well. This monitor supports both NVIDIA G-SYNC Compatible and AMD FreeSync Premium, minimizing screen tearing and stuttering for a fluid gaming experience. The 240Hz refresh rate gives competitive players a tangible advantage in tracking enemy movements. The distinctive Alienware design with customizable AlienFX RGB lighting on the rear adds to the gaming atmosphere.
Connectivity & Compatibility
The AW2521HF offers three video inputs: one DisplayPort 1.2 and two HDMI 2.0 ports. For full 240Hz operation, you must use the DisplayPort connection; HDMI caps at 144Hz at 1080p. A built-in USB 3.0 hub (one upstream, four downstream) provides convenient connectivity for peripherals. Variable refresh rate (VRR) works with both NVIDIA G-SYNC Compatible (GeForce GTX 10-series and newer) and AMD FreeSync Premium (Radeon RX 500-series and newer). Console users can achieve 120Hz output on PS5 and Xbox Series X, but the lack of HDMI 2.1 means no support for 1440p/120Hz simultaneous output.
Product Info
Launched in May 2020, the AW2521HF sits in the "entry-high" tier of gaming monitors. It delivers competitive-grade specs—240Hz, Fast IPS, G-SYNC Compatible—at a price that has fluctuated from around ¥60,000 at launch to approximately ¥135,000 on currently. With newer models like the AW2523HF now available, you may find this unit on sale at more attractive prices. The monitor comes with a standard 3-year warranty. Included accessories are a DisplayPort cable, HDMI cable, USB upstream cable, power cable, and quick-start guide. The stand offers height, tilt, swivel, and pivot adjustments, and VESA 100×100mm mounting is supported.
Best Use Cases
Competitive FPS gamers: The 240Hz refresh rate and 1ms response time are ideal for titles like Valorant, Apex Legends, and CS:GO. The Fast IPS panel balances speed with viewing angles, reducing eye strain during long sessions. eSports enthusiasts and streamers: High refresh rates make gameplay footage smoother for both playing and watching. However, HDR performance is limited, so HDR-focused users should look elsewhere. * Dual-monitor gamers: The 24.5-inch size fits well as a secondary display, and VRR support helps minimize visual discrepancies when pairing with a 60Hz monitor.
Things to Consider
The AW2521HF is limited to Full HD (1920×1080) resolution. If you prefer larger screens or 4K, this isn't the right choice. DisplayPort 1.2 lacks DSC, so 240Hz requires DisplayPort—HDMI tops out at 144Hz. At its current price, it faces stiff competition from similarly specced models like the ASUS VG259QM and BenQ ZOWIE XL2546K. Waiting for a sale or considering the newer AW2523HF may be wise. Also note that the monitor has no built-in speakers, so you'll need separate audio solutions. ## FAQ
Q: Can I get 240Hz on PS5? A: No. PS5 outputs up to 120Hz at 1080p via HDMI. The AW2521HF's HDMI 2.0 supports 120Hz, but 240Hz requires DisplayPort, making it a PC-only feature. Q: Which GPUs work with G-SYNC Compatible? A: NVIDIA GeForce GTX 10-series and newer (including RTX 20-series and later) are officially supported. AMD Radeon GPUs work via FreeSync Premium. Q: Does it reduce eye strain? A: Yes, the monitor is flicker-free and includes a blue-light reduction mode. The high 240Hz refresh rate also reduces motion blur, which can help lessen eye fatigue during extended use.
