On November 24, thirty-two teams will sit down at the Singapore Indoor Stadium and play the first Counter-Strike Major ever held on OLED. The monitor is the ROG Swift OLED PG259QWS Ace, and its headline number is the kind of spec that sounds like a typo: 720Hz, native 1080p, on a 24.5-inch panel built specifically for this event.
If you bought a 240Hz or 360Hz panel in the last two years, the obvious question is whether you just got left behind. We ran the math. The entire step from 540Hz to 720Hz buys 0.46 milliseconds of frame time, less than a quarter of one percent of a human reaction. By that measure, the fastest Major in Counter-Strike history changes almost nothing.
So the more interesting question is why the most display-conservative esport on earth abandoned the LCD technology it has trusted for fifteen years, on its single most-watched stage.
What is on the stage in Singapore
PGL CS2 Major Singapore 2026 runs November 24 through December 13: three 16-team Swiss stages, then a single-elimination playoff, $1,250,000 on the line, the first Major ever held in Southeast Asia. ASUS announced the monitor partnership on August 25. “The Major is where the best in the world prove themselves, and it deserves the best monitor in the world,” said Vincent Chiou, ASUS corporate vice president and general manager of the display business unit. “It’s the fastest display, on the biggest stage.”
The panel inside the PG259QWS Ace is built for esports: LG Display confirmed in September that it is mass-producing this 24.5-inch OLED “tailored specifically for Esports,” and the Ace is the first monitor confirmed to use it. The panel runs 720Hz at full 1080p. That distinction matters, because the other 720Hz OLEDs on the market, including Sony’s Inzone M10S II (540Hz at QHD, 720Hz only in a downscaled 720p mode, also $1,099), reach the number by cutting resolution. When Optimum tested that dual-mode trick on ASUS’s own 27-inch flagship, he called the 720Hz 720p mode “pretty rough,” with long-range fights where he was “basically just looking at a collection of pixels.” The Major’s monitor never downgrades: 720 frames, full 1920 x 1080, every second.

The rest of the monitor is built from pro feedback rather than spec-sheet chasing: a Position Sensor so players can reproduce their exact monitor placement at every venue, an export-and-share settings profile system, three esports color modes, a proximity sensor and GaNFET cooling to manage heat and burn-in risk, and a 3-year burn-in warranty. These are tournament-survival features. They tell you what ASUS is worried about.
Why Counter-Strike stayed on TN this long
To understand what just happened, you have to appreciate how stubbornly Counter-Strike has refused it. We pulled the current pro monitor data from CSDB’s settings database, which tracks 1,011 professionals:
What 1,011 CS2 pros actually play on
Share of tracked pro-monitor pairings by brand, CSDB database, 2026.
Every ZOWIE model in that 91% is a TN LCD. The most-used single monitor is the 360Hz XL2566K (25.4% of pros). Source: CSDB.gg, hand-curated from team announcements, streams, and interviews.
Ninety-one percent of the best Counter-Strike players on earth use TN LCDs, and zero of them were using OLED before this announcement. The features that did the work were near-instant pixel response and DyAc backlight strobing, which flashes the backlight in sync with refresh to freeze motion. OLED could never do the second one, and until this generation it could not do the first one fast enough at esports refresh rates either.
The stage history shows the ladder CS climbed to get here. PGL Major Copenhagen 2024 ran 360Hz XL2566K panels on every stage. IEM Katowice, the other flagship event on the circuit, now runs the 600Hz XL2586X+ under a deal covering 2025 to 2027. And here is the counterpoint that keeps this honest: the 600Hz TN is not dying. By TwitchStorm’s 2026 pro-gear tracking, the XL2586X+ is used by 38% of pros and gained 13 more since December 2025. Pros were still migrating toward faster TN right up until the moment OLED took the Major stage.
Also remember how CS is played: pros run low settings at 1280 x 960 stretched across the panel. They optimize for frame rate and target visibility first, with image quality last on the list. That is a tough audience for a technology whose traditional pitch is that it looks better.
Is the move to 720Hz worth it?
A monitor can only show you a new frame once per refresh interval, and that interval is 1000 divided by the refresh rate:
The diminishing-returns curve, 60Hz to 720Hz
Frame interval in milliseconds versus refresh rate. Nearly all of the gain falls inside the shaded zone.
Frame interval = 1000 / refresh rate. Total gain from 60 to 720Hz is 15.28ms; 12.49ms of it arrives by 240Hz. Our calculation from the definition of refresh rate.
Going from 60 to 144Hz removes 9.72ms from every frame, which is 63 percent of the total improvement available between 60Hz and 720Hz. Going from 540 to 720Hz, the step this Major advertises, removes 0.46ms. Doubling the refresh rate from 360 to 720 buys 1.39ms. Past 360Hz, the curve is nearly flat.
For scale, put that 0.46ms next to the thing it is supposed to improve:
0.46ms inside a real reaction
Top: a typical 200ms visual reaction budget. The full 540-to-720Hz gain is too small to draw at this scale. Bottom: zoom in to the first 5 milliseconds and it becomes visible, next to the frame intervals it replaces.
Reaction-time figures are the standard range for simple visual response tasks; elite FPS players test at the fast end. Our illustration, built from the frame-interval math above.
There is one more refinement worth knowing. A target that appears at a random moment is, on average, revealed half a frame late. That makes average detection latency 2.08ms on a 240Hz panel and 0.69ms on a 720Hz one: a 1.4ms saving for someone upgrading across that whole gap. Real, measurable, and still under one percent of the time it takes a human to respond to what they see. Nobody wins a duel because their monitor refreshed 0.46ms sooner.
Try 60Hz, then 240Hz, then 540Hz. Watch the opportunity collapse.

OLED cleared the speed bar. TN held the esports throne on two claims: fastest pixels, and strobed motion clarity no OLED could match. This panel answers both. At 0.02ms, every one of its 720 frames is fully drawn before the next one begins, while an LCD’s pixels are still transitioning through a meaningful slice of a 1.67ms frame at 600Hz. And sample-and-hold blur at 720Hz works out to 1.39ms of perceived motion smear, which is the neighborhood strobed LCDs reach, minus the flicker and the brightness penalty. That is why the holdout broke now and not two years ago.
The industry also rotated the spec race onto an axis where OLED wins structurally. Refresh rate is saturated; we showed the receipts above. Motion clarity and pixel response are the new contest, and TN has no answer for a panel that finishes every pixel transition in one fiftieth of its frame time. Even the direction of travel confirms it: Sony’s M10S II adds blur-reduction strobing to OLED, so OLED is now borrowing TN’s signature trick. Expect ZOWIE’s response to arrive fast, because its entire moat is now in question.
The Major is also a certification test. A Major stage is the harshest environment a display can face: three weeks of near-24-hour use, static HUDs parked on the same pixels, bright arena lighting, and zero tolerance for failure in front of the audience that watched 1.84 million people peak at the Copenhagen grand final. Burn-in is the reason OLED never touched this market, and it is the reason ASUS put a proximity sensor, GaNFET cooling, and a 3-year burn-in warranty into a tournament monitor. A clean run in Singapore certifies OLED for every LAN on the circuit and every bedroom that copies it, while a burn-in incident on the stream could set the technology’s esports push back years. ASUS and LG Display are betting the panel’s reputation on the answer.
How Counter-Strike got from TN to OLED in one supply chain
The questions Singapore will answer
The refresh rate only pays if the game renders at the refresh rate, and that is not guaranteed.
One: whether the stage PCs can sustain 720 frames per second. CS2 is CPU-bound, and community benchmarks put a Ryzen 9900X3D with an RTX 5090 around 600fps at 1080p with high settings, with substantially more headroom at the low settings and 1280 x 960 resolution pros use. PGL has not published the stage PC specs yet, so this is an open question with a plausible yes and no confirmation. One-percent lows matter more than averages here; a hitch during a spray transfer will be visible to every analyst desk in the building.
Two: whether pros will enable it at all. CS2 ships with an fps_max cap of 400 by default, so 720Hz requires someone to raise it. CSDB’s tracking of 404 pro configs says most already do: 70 percent run the cap uncapped, m0NESY sits at 999, donk at 600. But notice who is in the 400 club: ZywOo and NiKo, two of the best riflers alive, cap at 400 because a stable, predictable frame time beats a higher one. Some players at this Major will never look at a 720Hz frame, by choice.
Three: whether anyone will notice at 1280 x 960 stretched, at 720Hz, under pressure. Optimum, who has spent more hours testing 720Hz than any reviewer we know of, describes the jump past 540Hz in terms of feel rather than measurable aim.
What this means for your next monitor
Should you buy anything because of this Major?
What are you playing on right now?
Our buying analysis based on the frame-interval math above and current pricing: XL2586X+ at $999, PG259QWS Ace targeting $1,099 at its Q4 2026 release.
The one group that should pay close attention is everyone still below 240Hz, and the lesson for them is the same one every earlier refresh-rate step taught, with a new number attached: the first steps of the refresh-rate ladder are the only ones that were ever worth money. The Major changes nothing about that, whatever the marketing implies.
What will settle the OLED question in Singapore
From November 24, the stream will show whether the OLED era starts in Singapore. Watch whether the frame counters on the broadcast hold above 720 during utility-heavy executes, whether any player publicly complains about motion clarity or requests the old-style strobed look back, and whether the panels show any sign of retention or burn-in by the grand final on December 13. All three going right ends the fifteen-year TN era, and any one of them going wrong is its own story.
We will be watching the same list, and we will do what this site has always done with questions like this: test them ourselves. A 540Hz versus 720Hz aim study, in the tradition of our Aim Hero work, is on the bench for this cycle. Counter-Strike just put its biggest stage on a panel that buys 0.46 milliseconds. The number is trivial. What the panel is buying with those milliseconds, in front of a million-plus viewers, is certification.
