Overview
The ASUS ROG Strix XG248QSG Ace is a specialist esports monitor built around a 24.1-inch, 1920 × 1080 Super TN panel and a maximum advertised refresh rate of 610Hz through overclocking. This plan interprets “ASUS Ace” as this specific model, rather than ASUS gaming monitors generally. Its appeal is straightforward: a compact screen, very frequent image updates, and features aimed at keeping fast movement readable in competitive games. It prioritizes competitive play over the resolution, contrast, and large-screen presentation buyers might want for mixed entertainment.
The distinguishing feature beyond refresh rate is ASUS's ELMB 2 backlight-strobing technology, intended to reduce perceived motion blur. Strobing and a high refresh rate address different parts of motion presentation; neither should be treated as a guarantee of better aim. ASUS also advertises an extremely short pixel response time, but that specification is not a measurement of complete input latency. Independent testing of overshoot, usable strobing settings, and brightness matters more than the headline alone.
Who it's for
This monitor makes the most sense for players who spend most of their gaming time in titles such as Counter-Strike 2, Valorant, or Rainbow Six Siege and already own a PC capable of sustaining very high frame rates. The relatively small Full HD screen fits the established competitive-monitor format and is less demanding to render than 1440p or 4K. Players who sit close and want to keep the action within a compact field of view may prefer it to a larger display.
It is a less natural choice for someone dividing time between spreadsheets, cinematic games, photo editing, and console play. A similarly priced OLED can provide much stronger contrast, while a high-refresh 1440p monitor offers more workspace and finer detail. Before paying for 610Hz, check frame rates in actual matches, including demanding scenes. A lower-refresh monitor paired with a more consistent system can be a better purchase than a flagship screen that rarely receives enough frames.
Things to know before buying
Check the manual for the connection, graphics-card support, and overclock settings needed to reach the maximum refresh rate. Do not assume every input exposes every refresh option, or that adaptive sync and backlight strobing work together at all settings. Backlight strobing can introduce visible flicker and change brightness, so buyers sensitive to either should prioritize a retailer with a practical return policy. TN viewing angles also make screen positioning important.
Compare the exact XG248QSG Ace model number across US listings; ASUS's other esports monitors are not interchangeable. Judge total delivered cost, authorized-seller status, warranty terms, and the dead-pixel return policy rather than the advertised discount alone. For alternatives, compare the ASUS PG248QP and BenQ's high-refresh ZOWIE TN models, especially on measured motion clarity and strobing behavior rather than refresh rate alone.
