The ROG Strix Ace XG248QSG gaming monitor puts the pedal to the metal with a 610Hz refresh rate

An esports competitor's gaming monitor is often a very specialized piece of hardware. Conventional displays don’t make the cut. These enthusiasts seek out models that are sized for up-close-and-personal viewing and specced out for astonishingly fast performance at relatively low resolutions. Generation after generation of ROG displays have fueled these gamers’ need for speed. Now, we’re ready to unveil our latest tournament-grade monitor: the ROG Strix Ace XG248QSG. 

Blazing-fast and supremely clear  

Checking in with a 610Hz refresh rate (OC, 600Hz native) and response times that dip all the way down to 0.1ms, the ROG Strix Ace XG248QSG stands out as the fastest gaming monitor that we’ve ever offered. It achieves this sky-high speed with a Full HD Super TN panel that delivers incredibly smooth animation, ensuring that gamers can spot and react to movement on the battlefield with lightning-quick precision. The monitor is G-SYNC Compatible and supports FreeSync Premium, too, so you can be sure that each frame is delivered with low latency and without tearing. Historically, TN panels haven’t always been known for their color production and brightness, but the Super TN panel delivers vivid colors as shown by its 90% DCI-P3 gamut coverage, keeping enemies and game UI elements from washing out into the scenery. 

A gaming monitor’s refresh rate is often its headlining feature, but gamers know that there’s more to the puzzle than just that one spec. Increasingly, gamers are putting low input lag on their display shopping checklist. A measurement of the complete time it takes for an input signal to be sent, processed, and presented on the display, input lag is affected by many elements of your PC setup. A low-performing monitor is a common culprit for dragging down an otherwise responsive system, so esports enthusiasts often hunt down the input lag that their display brings into the mix. The ROG Strix Ace XG248QSG is a standout in this regard, using GameFast Technology that delivers only 0.8ms input lag. That’s 2.25X faster than competing esports monitors.  

Beating blur with ELMB 2  

The ROG Strix Ace XG248QSG paints new frames with incredible speed and virtually no lag, and it also works overtime to banish the specter of motion blur. This monitor marks the debut of ASUS Extreme Low Motion Blur 2 (ELMB 2) tech, a new take on our blur-crushing technique that uses new dual backlight technology to enhance blur reduction performance. With two strips of backlight LEDs and ten total backlight zones, the XG248QSG offers exceptional clarity for objects in motion, giving you better tracking of opponents in the heat of battle. 

ELMB 2 is a backlight strobing technique designed to tackle the blur that arises from sample-and-hold. Unlike the CRTs of old, where a frame “fades” after it’s drawn, LCD displays draw the frame and hold it on screen until the next frame is drawn. That means that, even though your eyes constantly move as you track moving objects on your display, each frame is actually static, and the contrast between the persistence of each image and the movement of your eyes creates perceptual blur.  

Backlight strobing diminishes perceptual blur by turning off the backlight between refreshes, but earlier versions of the tech required some tradeoffs. While many gamers appreciated the blur-besting tech of our first-gen solution, for example, they asked us to explore ways to boost display brightness with the feature enabled. Through ELMB 2’s dual backlight technology, we’re able to make that happen. The ROG Strix Ace XG248QSG offers 370 nits of brightness with ELMB 2 enabled at its recommended level three setting. That’s roughly three times brighter than the first-generation tech, and 65% brighter than comparable solutions from our competitors. 

Another concern that gamers raised is that the increased clarity that comes with backlight strobing wasn’t equally apparent across the entire display. Previous implementations of the tech strobed the entire backlight at once, but monitors scan out row by row, creating a timing problem. The tech could create an optimal zone of clarity in the center of the screen — which is, to be fair, where gamers focus most of their attention — but blur and strobe crosstalk might appear in other regions of the screen, particularly the upper right and lower right corners. 

ELMB 2 addresses this problem with a multi-zone edge backlight. It allows for independent pulse control for each region of the display. We can time the backlight strobe for each segment of the display separately, ensuring low motion blur across the entire display. Between ELMB 2, its 610Hz refresh rate, and its excellent average response time, which tackles the blur caused by pixel transitions, the ROG Strix XG248QSG can offer an astounding level of visual clarity for fast-paced competitive gaming.  

Designed with esports setups in mind  

Examine the PC setups of many esports professionals, and you’ll find that they prefer to sit close to a relatively small gaming monitor. The ROG Strix Ace XG248QSG’s 24.1-inch display fits that bill nicely, but there’s more. We’ve reduced the footprint of its stand by 30% compared to the current ROG Strix XG Series stand design, ensuring  that the stand doesn’t interfere with your mousing hand in the middle of the action. A wide range of ergonomic adjustments, including an impressive 160mm height adjustment range and the ability to tilt the display backward a full 35°, let you position the display just where you need it. If you need even more granular control over the display’s positioning — and even more desk space underneath it — grab an ROG Ergo Monitor Arm to get it positioned just right.  

The ROG Strix Ace XG248QSG equips you for success 

 In the hyper-competitive world of esports gaming, speed makes all the difference. The lightning-quick 610Hz refresh rate and astonishingly low 0.8ms input lag of the ROG Strix Ace XG248QSG make it an instant contender for your esports rig.
