ASUS ROG Strix XG248QSG Ace 24.1" 610Hz 1080p TN Monitor
The ASUS ROG Strix XG248QSG Ace is a 24.1-inch esports gaming monitor built for professional FPS players who need the absolute fastest frame delivery available. Its Super TN panel runs at 610Hz (overclocked) with a 0.1ms minimum response time and 0.8ms input lag, reducing motion blur to a level that gives a measurable edge in competitive play. ELMB 2 technology simultaneously handles blur reduction and delivers visuals three times brighter than the previous generation, so nothing is sacrificed for speed.
Why this product
610Hz refresh rate for the sharpest motion clarity
Running at 610Hz (overclocked), this is described by ASUS as the world's fastest TN panel — every frame arrives with minimal delay between what happens in-game and what appears on screen.
0.8ms input lag, 56% lower than 600Hz rivals
Input lag is measured at 0.8ms, which ASUS states is 56% lower than other 600Hz monitors — a direct advantage in reaction-time-dependent genres like FPS.
ELMB 2 cuts blur and triples brightness
Extreme Low Motion Blur 2 enhances blur reduction performance while offering 3× brighter visuals versus previous-gen ELMB, so fast movement stays clear without dimming the image.
VRR works with both AMD and NVIDIA
FreeSync Premium and G-SYNC Compatible certification means variable refresh rate is available whether the connected GPU is from AMD or NVIDIA.
Smaller footprint, more desk space
The redesigned stand has a reduced footprint compared to previous ROG monitor stands, freeing up room for a larger mouse mat and keyboard.
DisplayWidget Center for on-screen control
ASUS's exclusive DisplayWidget Center lets users adjust OSD settings and monitor configuration directly with a mouse, without reaching for physical buttons.

- AMD FreeSync Premium certified for tear-free play on AMD Radeon GPUs.
- VESA mount compatible, and includes a tripod socket for broadcast and tournament setups.
- 610Hz requires an overclocked mode; the source GPU and cable must support the necessary bandwidth — verify your GPU's maximum output before purchasing.
- No built-in speakers — a separate audio output (earphone jack) is provided, but sound must come from headphones or external speakers.
Best for
- Competitive FPS players who prioritise the lowest possible input lag and motion blur over all other image characteristics.
- Tournament and LAN participants who need a monitor that can be tripod-mounted and transported, matching professional event setups.
- Mixed-GPU households where the monitor may be used with NVIDIA or AMD cards at different times — VRR works with both.
- Space-conscious setups where a smaller stand footprint is needed to keep room for a full-size mouse mat.
Trade-offs
- Colour-critical creative work: the Super TN panel covers 90% DCI-P3 and 125% sRGB, but TN technology has a narrower viewing angle (170°/160°) compared to IPS or OLED panels.
- Wide viewing angle needs: TN panels are designed for a single viewer directly in front — the 170°/160° viewing angle means colour and contrast shift noticeably off-axis.
- High dynamic range priority: certification is VESA DisplayHDR 400 with a 400 cd/m² peak and 1000:1 contrast ratio — buyers seeking deep HDR contrast should look at higher-tier HDR specifications.
- Audio through the monitor: there are no built-in speakers; users who rely on monitor audio need a separate solution.
