Performance Breakdown: Motion and Gaming Prowess

What sets the AW2521HF apart is its motion handling, scoring top marks for gaming. At 240Hz, it delivers buttery-smooth gameplay with minimal ghosting. Our tests show input lag at just 3.6ms in game mode—imperceptible even in fast-paced FPS battles. Backlight strobing (MBR) and motion blur reduction further reduce blur by up to 80% compared to standard 144Hz panels.

Variable refresh rate via NVIDIA G-Sync Compatible eliminates tearing without the premium price tag of native G-Sync modules. Pixel response time averages 0.3ms gray-to-gray, making it a favorite for pro players.

Image Quality Deep Dive

• Brightness: Peaks at 350 cd/m² in SDR (70/100 real scene score), solid for dimly lit rooms but not ideal for bright offices.
• Contrast: 1000:1 dynamic ratio, but native scores low at 46/100—blacks look grayish in dark scenes.
• Uniformity: Exceptional at 99% center light uniformity and 96% black uniformity, no dirty screen effect.
• Color Accuracy: Delta E of 1.4 (pre-calibration)—professional-grade out of the box. Covers 99% sRGB, 85% DCI-P3, perfect for vibrant games.
• Viewing Angles: 170° horizontal/160° vertical; colors shift at extremes (typical TN), so center seating is best.

No HDR support is a con, but for 1080p esports, SDR suffices. Calibrate via Dell software for even better results.

Build Quality, Ergonomics, and Features

The matte anti-glare coating minimizes reflections, and the slim bezels enhance immersion. Stand offers full adjustability:

• Height: 5 inches
• Swivel: ±20°
• Tilt: -5°/21°
• VESA 100x100 compatible

Ports include 2x HDMI 2.0, 1x DisplayPort 1.2, and a headphone jack. Five USB 3.0 hubs (downstream) make it a connectivity hub—no USB-C though. No built-in speakers, so pair with external audio.

Weight: 8.5 lbs without stand; durable plastic chassis withstands LAN party abuse.
