1. Refresh Rate and Extreme Clarity (400Hz)
Operating at a native 400Hz refresh rate, the XL2566X significantly shortens the time between frames to a mere 2.5 milliseconds. This speed ensures that your input is registered and displayed nearly instantly, which is vital for quick-reaction FPS games. The use of the 24.1-inch format is intentional, as this size is proven in the esports scene to be the sweet spot for maximizing visual information without requiring excessive eye movement.
The speed offered by this 400Hz esports monitor ensures that even in the most chaotic, high-speed firefights, the image remains coherent and easy to follow. This clarity helps reduce eye fatigue during long practice sessions, a practical benefit for serious players.
2. DyAc+ 2.0 Strobing Technology
DyAc+ 2.0 is the secret weapon for this ZOWIE monitor. While 400Hz already provides incredible fluidity, DyAc+ 2.0 works by strobing the backlight, effectively "wiping" the previous image from your retina before the next frame is drawn. This dramatically reduces the motion blur inherent in all sample-and-hold displays.
The benefit is a visually "cleaner" motion. When you track a moving opponent, they appear as a sharp, distinct object rather than a blurry streak. This makes target tracking, especially with automatic weapons, significantly easier and more accurate. DyAc+ 2.0 at this refresh rate is a true competitive advantage in motion clarity.
3. Console Compatibility and Physical Adjustments
While primarily a PC esports display, the XL2566X includes HDMI 2.1, which is a thoughtful inclusion for modern console gamers. This port allows the monitor to fully support 120Hz output from the latest generation of consoles, making it a great single display solution for cross-platform competitive gamers.
In terms of physical design, the monitor features the signature ZOWIE adjustable stand, offering extensive height, tilt, and swivel customization. This is coupled with the external S Switch, a physical controller that allows you to instantly switch between your saved profiles (e.g., a "Valorant" profile, a "Destiny 2" profile, etc.). This focus on user-centric control and consistent performance is what makes the monitor a staple in the DyAc+ 2.0 features category.
