In the high-octane world of competitive gaming, where a split second can make or break a victory, ASUS has unveiled a game-changer at Computex 2025. The ROG Strix Ace XG248QSG isn’t just another gaming monitor—it’s the fastest ever crafted, boasting a staggering 610Hz refresh rate. This screen is a tribute to esports pros and speed-hungry gamers who thrive on precision.
Driving the ROG Strix Ace XG248QSG is its 24.1-inch Full HD Super TN panel, a display tech that prioritizes raw velocity over visual extravagance. With a native 600Hz refresh rate that can be pushed to 610Hz, this monitor redraws the screen 610 times per second. To give you a sense, that’s over 10 times quicker than the standard 60Hz displays in most homes or offices. It’s so fast that a single blink—roughly 100 milliseconds—could miss over 60 frames of action. For titles like Counter-Strike 2 or Valorant, where catching an enemy’s slightest move is everything, this speed is a game-winner.
- 32-inch 4K (3840 x 2160) QD-OLED gaming monitor with 240 Hz refresh rate and 0.03 ms (GTG) response time for immersive gaming
- Highly efficient custom heatsink, advanced airflow design, and graphene film for better heat management to reduce the risk of burn-in
- VESA DisplayHDR 400 True Black compliance, 99% DCI-P3 gamut, true 10-bit, and Delta E < 2 color difference for astonishing HDR performance
The monitor’s response time is just as wild: 0.1 milliseconds (gray-to-gray). Yes, you read that right. It’s the kind of responsiveness where the screen reacts to your inputs faster than you can process them. ASUS pegs the input lag at a mere 0.8 milliseconds, 56% lower than rival 600Hz monitors. Practically speaking, your mouse clicks and keyboard taps become on-screen actions with near-instant precision.
A high refresh rate isn’t the whole story for crisp visuals. Older LCDs, unlike vintage CRTs, hold each frame steady until the next arrives, which can smear fast-moving objects as your eyes track them. ASUS counters this with Extreme Low Motion Blur 2 (ELMB 2), a backlight strobing trick that’s been turbocharged for 2025. Unlike its earlier version, ELMB 2 employs two LED backlight strips split into 10 zones, each timed independently to sync with the monitor’s row-by-row scan. The payoff? Motion blur is all but eliminated across the entire screen, not just the middle.
Better still, ELMB 2 doesn’t plunge the display into darkness like older strobing tech. At its sweet spot, the monitor delivers 370 nits of brightness—three times brighter than ASUS’s original ELMB and 65% brighter than competitors’ efforts.
The trade-off for this speed is resolution. At 1080p, the XG248QSG won’t deliver the visuals, an OLED or Mini-LED monitor will serve you better. But for the niche of competitive gamers who measure their skill in frames per second, this monitor is a revelation. It’s not just about the 610Hz headline—it’s the combination of low input lag, ELMB 2’s motion clarity, and a design tailored for esports that makes it feel like a secret weapon. ASUS has taken the TN panel, often dismissed as outdated, and turned it into a precision tool for the modern battlefield.
