A monitor designed to dominate esports competition
The ASUS ROG Strix XG248QSG Ace stands out as a ultra-fast gaming monitor, specially designed for professional FPS players. With its 24.1-inch Super TN FHD (1920 x 1080) screen, it combines an exceptional 610 Hz refresh rate and a 0.7 ms (GTG) response time for perfect responsiveness. Ideal for demanding users, this monitor turns every millisecond into a competitive advantage, whether for tournaments or intense gaming sessions.
High performance for competitive players
The ROG Strix XG248QSG Ace is based on a Super TN panel, the fastest in the world, offering a response time of 0.1 ms (min) / 0.7 ms (GtG) and input lag reduced to 0.8 ms, 56% less than other 600 Hz monitors. This technology almost completely eliminates the delay between commands and display, allowing players to react with extreme precision.
Support for VRR (60-610 Hz with DisplayPort), AMD FreeSync Premium and NVIDIA G-SYNC compatibility guarantees smooth, tear-free images, even in the most dynamic scenes.
Clarity and comfort for extended sessions
Thanks to Extreme Low Motion Blur 2 (ELMB 2) technology, this monitor effectively reduces motion blur and ghosting, while offering brightness up to 65% higher than competing solutions. The color gamut extended to 90 % DCI-P3 delivers a rich and accurate visual experience.
Its compact design frees up desk space, while its ergonomic stand (swivel, tilt, height adjustment) adapts to all postures. Finally, the DisplayWidget Center simplifies settings management through an intuitive interface.
An AI-optimized experience
The ROG Strix XG248QSG Ace integrates advanced AI-powered features such as AI Visual, Dynamic Crosshair and Dynamic Shadow Boost to improve visibility and in-game precision. Its display format control lets you adjust the aspect ratio according to players' preferences, while its comprehensive connectivity options (HDMI 2.1, DisplayPort 1.4, headphone jack) ensure optimal compatibility with modern setups. Perfect for players seeking pure performance, it combines speed, responsiveness and comfort for total immersion.
