Gamescom 2026 turned into an unplanned refresh-rate showdown. On August 28, ASUS used the Cologne show floor to unveil three new ROG OLED esports monitors built around a 720Hz panel, calling it a world first for the format. Samsung answered within 48 hours, confirming that its Odyssey G6 display can hit 1,100Hz when it drops to 720p resolution, a number that eclipses ASUS’s headline figure even though the two companies are measuring different things.
The dueling announcements land in a gaming monitor market that Future Market Insights pegs at roughly $11.4 billion in 2025, growing toward $12.1 billion by the end of 2026. They also arrive alongside new entries from LG, Gigabyte and AOC, turning late August into the most crowded stretch of high-refresh monitor launches this year. What follows is a look at what ASUS and Samsung actually shipped, how the numbers hold up against independent refresh-rate research, and what the fight over triple-digit-Hz displays means for buyers who are not professional esports athletes.

ASUS Unveils Three 720Hz OLED Monitors at Gamescom 2026
ASUS’s Republic of Gamers division used its Gamescom 2026 keynote on August 28 to introduce a trio of 24.5-inch OLED monitors: the ROG Swift OLED PG259QWS Ace, the ROG Strix OLED XG259QDPG Ace and the ROG Strix OLED XG259QDNS Ace. All three share the same headline spec, a 720Hz refresh rate that ASUS is marketing as a world first for an OLED gaming panel, and all three carry the “Ace” branding the company reserves for its top competitive-play hardware.
The 24.5-inch, 1080p-class form factor is a deliberate choice. It matches the footprint pro players already use at LAN events and mirrors the panel size ASUS has shipped in prior 360Hz and 540Hz esports monitors, so the jump to 720Hz slots into an existing competitive-hardware category rather than creating a new one. ASUS is positioning the panels for exactly the titles where refresh rate has historically mattered most in competitive circles: Valorant, Counter-Strike 2 and League of Legends, games that top-tier hardware can push well past 500 frames per second at low settings.
The monitors were shown alongside a wider ROG hardware push at the Cologne event, including new gaming peripherals, routers and limited-edition graphics cards, underlining that ASUS is using Gamescom as a full product-line moment rather than a single-SKU announcement. ASUS has not yet published pricing or a shelf date for the three new panels, which is typical for its Gamescom reveals; the company historically confirms final pricing closer to a CES or retail-availability window.
Samsung Trumps It With a 1,100Hz Odyssey G6
Samsung’s response came from a different part of its lineup. The Odyssey G6, a 27-inch fast-IPS monitor rather than an OLED panel, runs natively at 2560×1440 resolution up to 600Hz. Switch it into a quarter-resolution Dual Mode at 1280×720, and the panel scans up to 1,100Hz, a spec Samsung finalized at Gamescom 2026 after first teasing a lower 1,040Hz figure around CES earlier in the year. At 1,100Hz, each frame is on screen for less than a millisecond, a frame time of roughly 0.91ms according to Tom’s Hardware’s teardown of the announcement.
That 1,100Hz number is not a fair apples-to-apples match against ASUS’s 720Hz panels. Samsung’s figure requires dropping to 720p and a non-OLED fast-IPS panel, while ASUS’s 720Hz spec runs on a full-fat OLED panel without a resolution trade-off. The comparison still matters commercially, because both companies are chasing the same headline: the single biggest refresh-rate number they can put on a spec sheet at the same trade show, in front of the same buyers.
Samsung has quoted a 1ms gray-to-gray response time for the G6 and says the monitor will reach global availability in the second half of 2026, without confirming a price. Because the G6 sits at the bottom of Samsung’s new Odyssey stack on panel technology (fast IPS instead of OLED), it is positioned as the value-and-speed option in a lineup where the pricier models trade raw Hz for OLED contrast and color.
What 720Hz and 1,100Hz Actually Mean in Practice
A 240Hz monitor refreshes every 4.17 milliseconds. Push that to 360Hz and the frame time drops to 2.78ms, a gain of 1.39ms, according to frame-time breakdowns compiled by hardware research site Industrial Monitor Direct. Going from 240Hz to 480Hz buys roughly another 1.39ms on top of that. Each further doubling of refresh rate keeps producing progressively smaller absolute time savings, even though the headline Hz numbers keep doubling.
That mathematical reality does not mean 720Hz and 1,100Hz panels are pointless. Nvidia’s own 2019 research on latency and refresh rate in competitive gaming tasks found that performance improved monotonically as refresh rate climbed, and the company concluded that 240Hz, its top display speed at the time, provided a measurable competitive advantage over lower refresh rates. A follow-up Nvidia Research publication dated June 2026 revisited the question with newer panels and found that gamers can reliably tell the difference between large refresh-rate jumps, but that perceptual and performance gains shrink as the baseline refresh rate climbs, with 144Hz flagged as a point beyond which further increases deliver comparatively marginal returns for most players.
The Diminishing-Returns Problem
A 2022 study published in PMC found the positive effect of higher refresh rates is strongest moving from 60Hz to 120Hz, and that the benefit gradually flattens out above 120Hz. Separately, LG’s own internal research, cited in 2026 coverage, found an extra 10% aim-accuracy advantage moving up to 480Hz, suggesting the curve has not fully flattened by that point, but no publicly available study has yet measured a meaningful human-perceptible benefit specifically between 480Hz and the 720Hz to 1,100Hz range ASUS and Samsung are now shipping. In practice, that means the newest panels are being built for a sliver of players: sponsored esports athletes and enthusiasts chasing marginal edges, rather than the broader gaming monitor buyer.
Samsung’s Full 2026 Odyssey Lineup: G9, G8, G7 and G6
The Odyssey G6 was not shown in isolation. Samsung used Gamescom 2026 to reveal an updated four-model Odyssey range that spans from the speed-focused G6 up to a 49-inch ultrawide flagship. The Odyssey G9 remains Samsung’s 49-inch QD-OLED super-ultrawide, continuing the 32:9 format the company has shipped in prior G9 generations. The Odyssey G8 is a 32-inch flat OLED panel aimed at 4K gaming, and the Odyssey G7 is a 27-inch OLED model positioned as a high-refresh QHD alternative for players who want OLED contrast without paying for the largest screen sizes. Adding to the naming overlap, Samsung already sells a separate Odyssey OLED G6 sub-line that predates the Gamescom reveal: Samsung Canada listed the 27-inch G61SH at 240Hz with 178/178-degree viewing angles as of January 2026, DisplayNinja reviewed the 27-inch G65B at 4.3 out of 5 in February 2025, and Press-Start tested the 500Hz, 1440p G60SF on August 21, 2025, meaning the new fast-IPS G6 is arriving alongside, not instead of, an entire family of existing OLED-branded G6 monitors.
The G6 is the only non-OLED panel in the new stack, running fast-IPS LCD technology instead. That makes it the odd one out on paper, but also the fastest by a wide margin: none of the OLED models in the G7 through G9 range claim anything close to the G6’s 600Hz native or 1,100Hz Dual Mode figures. Samsung has not disclosed pricing for any of the four models, and none have confirmed shelf dates beyond the general “second half of 2026” window given for the G6.
How the New ASUS Monitors Fit Its Existing OLED Range
ASUS already sells a deep bench of OLED gaming monitors, and the new 720Hz models slot in above all of them. The ROG Swift OLED PG27AQDM-R, a 26.5-inch QHD panel at 240Hz, currently lists for $699 and has sold as low as $549 in limited-time promotions, according to PCGuide’s deal coverage. One tier up, the ROG Swift OLED PG27AQDP runs a 480Hz QHD panel and lists around $1,000, per DisplayNinja’s review of the model. Both carry ASUS’s standard three-year warranty, which the company explicitly extends to cover OLED burn-in, backed by onboard mitigation tools including a proximity sensor, automated pixel cleaning, pixel shift and a screen saver mode.
If ASUS prices the new 720Hz Ace models consistent with that existing ladder, expect them to land above the $1,000 480Hz tier, likely putting the flagship panels somewhere in the $1,200 to $1,500 range once pricing is confirmed. That would keep them well above Nintendo Switch 2 and comparable console-tier hardware pricing, positioning the monitors squarely as enthusiast and sponsored-player purchases rather than mainstream upgrades.
The Broader Refresh-Rate Race: LG, Gigabyte and AOC Join In
ASUS and Samsung are not fighting this battle alone. LG confirmed U.S. pricing for its UltraGear 25G590B on August 24, 2026, a 25-inch Full HD monitor it calls the world’s first native 1000Hz display, priced at $999.99 with preorders open immediately and shipments targeted for September 3, 2026. LG’s monitor undercuts Samsung’s 1,100Hz figure but does so at native resolution rather than a stepped-down Dual Mode, which makes its claim more directly comparable to ASUS’s native 720Hz OLED spec than Samsung’s is.
Elsewhere in the market, Gigabyte’s MO27Q28GR, a 280Hz Tandem OLED panel with a RealBlack Glossy finish, went official at CES 2026 in January and remains one of the higher-end Tandem OLED options on the market. AOC took the opposite approach, adding the AGP277KXM to its lineup on August 29, an Ultra 5K resolution, 180Hz Dual Mode mini-LED monitor with 2,304 local-dimming zones, prioritizing resolution and contrast over raw refresh rate. Together, the late-August cluster of launches shows the gaming monitor market splitting into two camps: one chasing maximum Hz, the other chasing maximum resolution and HDR performance.

OLED vs Fast IPS: Why Samsung Chose LCD for Its Fastest Panel
The panel-technology split between ASUS and Samsung’s fastest monitors is not a coincidence. OLED pixels illuminate individually and can theoretically switch faster than LCD subpixels, which is why ASUS is comfortable pushing an OLED panel to 720Hz. But OLED panels used at very high native resolutions and refresh rates face steeper manufacturing yield and heat-management challenges at the panel level, and fast-IPS LCD panels are a more mature, cheaper technology to push toward extreme Hz numbers, provided you are willing to drop resolution to get there, exactly what Samsung’s Dual Mode does. Samsung’s own OLED-branded G6 models illustrate that ceiling: RTINGS’ review of the Odyssey OLED G6 S27DG60 (G60SD), first published in July 2024 and refreshed as recently as September 2026, tops out at 360Hz, while Samsung Belgium’s listing for the G61SD variant, updated as of October 2025, highlights a 240Hz refresh rate and a 0.03ms response time, both well short of the 1,100Hz Dual Mode figure reserved for the new fast-IPS panel.
The tradeoff shows up in image quality rather than speed. OLED panels deliver per-pixel black levels and wider color gamuts that fast-IPS LCD cannot match, which is why Samsung kept OLED for its G7, G8 and G9 models and reserved fast IPS for the G6’s speed record. Buyers choosing between the two approaches are effectively choosing between best-in-class motion clarity at a lower resolution, or richer image quality with a more conventional (if still very high) refresh rate ceiling.
Market Impact: A Roughly $12 Billion Category Up for Grabs
Estimates of the global gaming monitor market vary significantly by research firm and methodology, but Future Market Insights, whose figures track closest to shipment-based estimates from other analysts, values the category at roughly $11.4 billion in 2025, rising to about $12.1 billion by the end of 2026 and projected to reach $22.9 billion by 2036, a 6.6% compound annual growth rate over that decade. Market researcher Omdia separately tracks unit shipments rather than revenue, and has reported gaming monitor shipments climbing sharply year over year as the category recovers from a broader desktop-monitor slowdown, with gaming panels now accounting for roughly a third of total desktop monitor shipments worldwide.
Against that backdrop, the Gamescom refresh-rate push is a margin play as much as a technology showcase. High-refresh flagship monitors carry ASUS’s and Samsung’s best gross margins in the category, and headline specs like 720Hz and 1,100Hz generate press coverage and social attention that a mid-range 240Hz panel cannot. Whether or not most buyers can perceive the difference, the marketing value of owning the “fastest monitor” claim at a major trade show is difficult for either company to pass up.
Refresh Rate Progression and Diminishing Returns
| Refresh Rate | Frame Time | Gain vs Prior Tier | Research Finding |
|---|---|---|---|
| 120Hz | 8.33ms | Baseline competitive tier | Strongest perceptible gain vs 60Hz, per 2022 PMC study |
| 240Hz | 4.17ms | 4.16ms faster than 120Hz | Nvidia’s 2019 research found a measurable competitive advantage |
| 360Hz | 2.78ms | 1.39ms faster than 240Hz | Gains “narrow to professional esports athletes,” per Newegg’s 2026 analysis |
| 480Hz | 2.08ms | 0.70ms faster than 360Hz | LG’s internal research found a 10% aim-accuracy edge at this tier |
| 720Hz (ASUS OLED) | 1.39ms | 0.69ms faster than 480Hz | No independent perceptual study published yet |
| 1,100Hz (Samsung G6, 720p Dual Mode) | 0.91ms | 0.48ms faster than 720Hz | Requires quarter-resolution mode; no independent study published yet |
Historical Context: From 60Hz to 1,100Hz in a Decade
60Hz was the standard gaming monitor refresh rate for most of the 2000s and early 2010s. The competitive gaming scene began pushing that ceiling upward with 144Hz TN panels in the mid-2010s, and by the back half of that decade 240Hz had become the mark of a serious esports display. The current run of launches shows how much faster that climb has become: Samsung showed a 4K 360Hz QD-OLED panel at Computex earlier in 2026, and LG’s 1000Hz UltraGear became one of this year’s most-searched gaming monitor stories before Gamescom even began. What used to take roughly five years to double now takes closer to twelve months, as ASUS, Samsung and LG each try to leapfrog the other’s headline spec before the next major trade show.
That acceleration mirrors what happened with GPU-side frame generation and upscaling technology over the same period: once one manufacturer proves a spec is technically achievable, competitors tend to match or exceed it within a single product cycle rather than waiting for the next generational refresh.
Competitive Landscape: Where ASUS and Samsung Diverge
ASUS is betting that OLED image quality plus a genuinely new refresh-rate ceiling, without a resolution penalty, will appeal to buyers who already trust its Swift OLED and Strix OLED product lines. Samsung is betting the opposite: that a headline number big enough to dominate a keynote slide, even if it requires a resolution tradeoff most competitive players already accept in exchange for higher frame rates, will draw more attention than a smaller, cleaner spec. Both approaches target the same buyer profile, sponsored and semi-professional esports players plus enthusiasts who follow hardware releases closely, rather than the mainstream 144Hz-to-240Hz monitor buyer who still makes up the bulk of gaming monitor sales.
Neither company has confirmed pricing, which keeps the near-term competitive picture unsettled. If ASUS prices its 720Hz Ace monitors near $1,200 to $1,500 as the existing OLED ladder suggests, and Samsung prices the new fast-IPS G6 closer to its predecessors in the $600 to $900 range, the two products may end up competing for different budgets entirely rather than head-to-head for the same buyer. Samsung’s own OLED G6 sub-line shows how quickly those prices can slide once a model has been on shelves for a while: a US listing for the 240Hz Odyssey OLED G6 G61SH had already dropped to sale pricing of $399 as of August 2026.
Pricing, Warranties and What Buyers Should Actually Expect
For buyers weighing whether to chase the newest refresh-rate record or stick with an existing 240Hz or 360Hz monitor, the practical guidance from the available research is consistent: the jump from 60Hz to 120Hz or 144Hz remains the single most impactful upgrade any gamer can make, according to the 2022 PMC study cited earlier. Beyond that, each additional tier buys measurably less, and reviewers largely agree a strong sweet spot is already on shelves: DisplayNinja’s July 2025 review of the Odyssey OLED G6 (G60SD) scored it 4.8 out of 5 overall and 4.9 out of 5 for performance, while the newest 720Hz and 1,100Hz panels sit in territory that has not yet been independently tested for real-world perceptual benefit.
Warranty coverage is worth checking regardless of which panel a buyer chooses. ASUS’s existing OLED lineup carries a three-year warranty that explicitly includes burn-in coverage, backed by onboard pixel-refresh and screen-saver tools, and it is reasonable to expect the new 720Hz models to carry the same coverage given they sit at the top of the same product family. Samsung has not detailed burn-in warranty terms for the OLED G7, G8 and G9 models in its new lineup, and because the G6 uses fast-IPS LCD rather than OLED, burn-in coverage is a moot point for that specific model.
Predictions: Where Gaming Monitor Refresh Rates Go Next
- Expect more manufacturers to adopt Samsung’s quarter-resolution Dual Mode trick over the next year, since it is a cheaper way to claim a record Hz number than pushing native-resolution panels further.
- OLED burn-in warranty terms will likely become a bigger purchase differentiator than raw Hz counts, as buyers grow more skeptical that anything above 360Hz delivers a noticeable edge outside sponsored competitive play.
- Prices on 240Hz OLED monitors should keep falling, following the pattern already seen with the PG27AQDM-R’s drop from $799 to as low as $549, as attention and premium pricing shift to the 480Hz-and-up tier.
- Expect Samsung to keep its fast-IPS G6 and OLED G7-G9 models on separate technology tracks rather than merging them, splitting its lineup between speed-first and image-quality-first buyers.
- GPU makers will face growing pressure to show real, non-upscaled frame rates above 500 fps at competitive settings, as reviewers increasingly point out that most modern esports titles are CPU-bound long before a 720Hz or 1,100Hz panel becomes the bottleneck.
Frequently Asked Questions
What is the fastest gaming monitor announced at Gamescom 2026?
By headline refresh rate, Samsung’s Odyssey G6 is the fastest, reaching 1,100Hz in its 720p Dual Mode. ASUS’s ROG Swift OLED PG259QWS Ace and its two Strix OLED siblings claim the fastest native OLED refresh rate at 720Hz without a resolution penalty.
Is the Samsung Odyssey G6 an OLED monitor?
No. The Odyssey G6 uses a fast-IPS LCD panel, not OLED. Samsung’s OLED models in the same 2026 lineup are the Odyssey G7, G8 and G9, none of which claim refresh rates anywhere close to the G6’s.
How much do the new ASUS 720Hz monitors cost?
ASUS has not announced pricing for the ROG Swift OLED PG259QWS Ace, ROG Strix OLED XG259QDPG Ace or ROG Strix OLED XG259QDNS Ace as of the Gamescom 2026 reveal. Based on ASUS’s existing OLED pricing ladder, where a 480Hz QHD model lists around $1,000, the new 720Hz flagships will likely land above that mark once pricing is confirmed.
When will the Samsung Odyssey G6 be available to buy?
Samsung has said the Odyssey G6 will reach global availability in the second half of 2026, without confirming an exact date or price.
Can most gamers actually notice the difference above 240Hz?
Independent research suggests the benefit shrinks significantly past 240Hz. A 2022 PMC study found the strongest perceptible gains occur moving from 60Hz to 120Hz, with diminishing returns above that, while Nvidia’s own 2026 research found perceptual and performance gains keep narrowing as refresh rates climb, identifying 144Hz as a point where further increases become marginal for most players. Sponsored and highly trained competitive players are the group most likely to benefit from tiers above 480Hz.
How does Samsung’s Odyssey G6 hit 1,100Hz if it’s a 27-inch monitor?
The 1,100Hz figure only applies when the monitor is switched into Dual Mode, which drops the resolution from its native 2560×1440 down to 1280×720, one quarter of the pixel count. At native QHD resolution, the panel tops out at 600Hz.
Does a higher refresh rate monitor need a more powerful graphics card?
Yes, in principle, since the monitor can only display frames as fast as the GPU (and CPU) can render them. In practice, most modern esports titles at competitive low-detail settings are limited by CPU performance well before a graphics card becomes the bottleneck, which is part of why reviewers question how many players will realistically sustain 700 or 1,000-plus frames per second outside benchmark conditions.
What other gaming monitors launched around the same time?
LG confirmed pricing for its 1000Hz UltraGear 25G590B on August 24, 2026, at $999.99. AOC added the AGP277KXM, an Ultra 5K 180Hz mini-LED monitor with 2,304 dimming zones, to its lineup on August 29. Gigabyte’s 280Hz Tandem OLED MO27Q28GR launched earlier in the year at CES 2026.
