For years, the pursuit of speed in competitive gaming carried an unavoidable spatial cost — OLED displays simply would not shrink below 27 inches, forcing esports players to choose between the technology they needed and the desk space they had. ASUS has now dissolved that constraint with the ROG Strix OLED XG259QWPG Ace, a 24.5-inch monitor built on LG Display's Tandem panel that delivers 540Hz refresh and 0.02ms response at 1080p. The choice of LG over the widely anticipated BOE signals a quiet but consequential realignment in the panel supply chain, as the Korean manufacturer stakes a claim
ASUS Debuts World's First 24.5" OLED Gaming Monitor With LG Panel at 540Hz
The constraint just ended. ASUS has unveiled the first 24.5-inch OLED gaming monitor.

Why does a 24.5-inch monitor matter so much to esports players? Isn't a bigger screen always better?
Mimi
Not for competitive gaming. Esports players sit close to their monitors—sometimes just 18 to 24 inches away. A 27-inch display at that distance means your eyes have to work harder to track everything. A smaller screen keeps the action tighter, more immediate. It's the difference between watching a tennis match from the baseline versus the stands.
Mark
And the 540 hertz refresh rate—is that actually useful, or is it marketing?
Mimi
It's useful, but with caveats. Most games can't render 540 frames per second. But in competitive shooters, where even a single frame can mean the difference between a hit and a miss, having that headroom matters. You're not always hitting 540, but when you do, you feel it.
Mark
Why did ASUS choose LG over BOE? BOE is cheaper, isn't it?
Mimi
Probably. But LG's Tandem technology is specifically engineered for high-refresh gaming. It's not just about cost—it's about having the right tool for the job. ASUS is betting that esports players will pay a premium for a panel built exactly for their needs.
Mark
What does this mean for Samsung?
Mimi
Samsung is still the volume leader, but they've been focused on larger, higher-resolution OLED monitors for creative professionals and general consumers. They've left the ultra-competitive gaming segment mostly untouched. This monitor shows there's a market there—and now Samsung has to decide whether to compete or cede the space.
Mark
Is this the beginning of a trend?
Mimi
Almost certainly. Once one manufacturer proves a market exists, others follow. We'll probably see more compact, high-refresh OLED monitors from different brands within the next year or two. The form factor barrier has been broken.
The Pulse
- Competitive esports players have long been forced to accept oversized 27-inch displays just to access OLED's speed advantages — a compromise that affected both desk ergonomics and in-game reaction geometry.
- ASUS's surprise selection of LG Display over the heavily favored BOE disrupts assumptions about who controls the next wave of gaming panel supply.
- LG is now projecting 1.5 million units in this segment, positioning itself as a serious challenger to Samsung's 4-million-unit dominance in the broader OLED market.
- The monitor's 540Hz refresh rate and near-instantaneous pixel response collapse the traditional trade-off between screen size and competitive performance.
- Pricing and availability remain undisclosed, leaving the market to speculate on whether this breakthrough will be accessible or aspirational for the players it was built to serve.
For years, the pursuit of speed in competitive gaming carried an unavoidable spatial cost — OLED displays simply would not shrink below 27 inches, forcing esports players to choose between the technology they needed and the desk space they had. ASUS has now dissolved that constraint with the ROG Strix OLED XG259QWPG Ace, a 24.5-inch monitor built on LG Display's Tandem panel that delivers 540Hz refresh and 0.02ms response at 1080p. The choice of LG over the widely anticipated BOE signals a quiet but consequential realignment in the panel supply chain, as the Korean manufacturer stakes a claim in a high-refresh, compact gaming segment that Samsung has largely left uncontested.
For years, OLED gaming monitors carried an unspoken minimum: 27 inches. Competitive players who needed millisecond-level responsiveness had no smaller option, forcing a trade-off between speed and the compact setups their play styles demanded. That ceiling has now been broken. ASUS unveiled the ROG Strix OLED XG259QWPG Ace — a 24.5-inch OLED monitor running at 540Hz with a 0.02ms response time at 1080p resolution. It is the first of its kind.
The panel's origin carries its own story. Industry observers had expected ASUS to source from BOE, the Chinese manufacturer with growing OLED ambitions. Instead, ASUS turned to LG Display, whose Tandem WOLED architecture proved capable of sustaining the extreme refresh rates competitive gaming demands. The decision marks a meaningful entry point for LG into a smaller-format gaming segment that Samsung — still targeting over 4 million panel units this year — has largely overlooked. LG is projecting 1.5 million units, a figure that reflects genuine strategic intent.
For the players this monitor targets, the specifications are not abstract. A 24.5-inch screen sits closer to the eye, reducing the visual sweep required to track fast movement. At 1080p, the resolution is sharp enough for the size while keeping GPU load manageable at extreme frame rates. The 540Hz ceiling means the display can render far more frames per second than most games produce — a compounding advantage in titles where every frame counts.
Price and ship date remain unannounced, which is standard at this stage. But the monitor's existence alone suggests the OLED gaming market is moving beyond its 27-inch comfort zone, and that the competition to supply those smaller panels is only beginning.
For years, if you wanted to game on an OLED monitor, you had to accept a certain size penalty. The smallest OLED displays on the market topped out at 27 inches, which meant competitive esports players—the ones who live and die by milliseconds of response time—had to choose between the speed they craved and the screen real estate they could actually fit on a desk. That constraint just ended. ASUS has unveiled the ROG Strix OLED XG259QWPG Ace, a 24.5-inch OLED gaming monitor that shatters the form-factor ceiling and delivers specs that read like science fiction: 540 hertz refresh rate, 0.02 millisecond response time, all at 1080p resolution. It is, by any measure, the first of its kind.
The surprise is not just that the monitor exists. It's where the panel came from. For months, industry watchers expected ASUS to source its compact OLED display from BOE, the Chinese manufacturer that has become a heavyweight in the OLED space. Instead, ASUS went with LG Display, the South Korean company that has spent years fighting to keep pace with Samsung's dominance in the panel market. The choice signals a significant shift in the competitive landscape. Samsung remains the volume leader, targeting over 4 million OLED panel units this year. But LG is now actively pursuing the smaller, higher-refresh gaming segment—a market Samsung has largely ignored—and is projecting 1.5 million units of its own. BOE, despite its scale and cost advantages, was passed over entirely.
The technical achievement here matters to a specific audience, but it matters intensely. Esports competitors have long operated under a constraint: to get the responsiveness they need, they had to accept 27-inch 1440p displays. Those are good monitors. But they're also large, and they sit further from the player's eyes, which can be a disadvantage in games where milliseconds and millimeters both count. A 24.5-inch 1080p OLED display with 540 hertz refresh and near-instantaneous pixel response time collapses that trade-off. It gives competitive players a monitor built to their exact specifications—small enough to fit their setup, fast enough to match their reflexes, and OLED enough to deliver the color accuracy and contrast that makes the image feel alive.
LG's Tandem WOLED technology is the engine here. It's a panel architecture designed specifically for high-refresh gaming, and the numbers bear that out. At 0.02 milliseconds of response time, the monitor is essentially instantaneous from a human perception standpoint. The 540 hertz refresh rate means the display can show 540 unique frames per second—far beyond what most games can render, but useful for competitive titles where every frame advantage compounds. At 1080p, the pixel density remains sharp enough for a 24.5-inch screen, and the lower resolution also means the graphics card driving the display doesn't have to work as hard to hit those extreme refresh rates.
What remains unknown is price and when the monitor will actually ship. ASUS has not disclosed either detail, which is typical for product announcements at this stage. But the existence of the monitor itself signals that the OLED gaming display market is maturing beyond the 27-inch, high-resolution sweet spot that has dominated for the past two years. Smaller, faster, more specialized displays are now possible. The question now is whether other manufacturers follow ASUS's lead, and whether LG's bet on this segment pays off in volume and market share.
