The PG259QWS Ace monitor headlines a fresh wave of ASUS ROG displays, and it arrives with a genuinely startling number attached: a 720Hz refresh rate. ASUS has used the announcement to expand its esports-focused Ace lineup to five models, while also introducing two new 27-inch monitors that can switch between resolutions and refresh rates on demand. Between them, the new screens cover everything from bedroom Counter-Strike hopefuls to buyers who want one monitor that does several jobs well.
What the PG259QWS Ace Monitor Brings to the Table
Sitting at the top of the new 24.5-inch FullHD range, the PG259QWS Ace monitor uses a Tandem WOLED panel tuned for competitive play rather than cinematic colour. Its headline figure is that 720Hz refresh rate, backed by a claimed 0.02ms response time and peak brightness of 1700 nits, numbers that put it well ahead of most gaming monitors currently on shelves.
ASUS has also built in a position sensor, a small but telling addition that lets players track their physical monitor setup, useful for anyone who fine-tunes desk height or angle as part of a competitive routine. Perhaps more significant for the wider esports scene is that PGL has chosen the PG259QWS Ace monitor as the official display for the 2026 CS2 Major, a strong endorsement given how closely tournament organisers scrutinise input lag and motion clarity before signing off on hardware. ASUS expects it on shelves in early Q4, priced at US$1,099.
The Rest of the Ace Series Lineup
The PG259QWS Ace monitor is not travelling alone. ASUS is also launching the XG259QWPG Ace, a 540Hz FullHD OLED display pitched at US$699, giving buyers a cheaper entry point into the same Tandem WOLED technology without the absolute peak refresh rate.
Two further models round out the 24.5-inch range: the 560Hz XG259QDPG Ace and the 360Hz XG259QDNS Ace. Both rely on RGB QD-OLED panels rather than Tandem WOLED, and both include ASUS’s BlackShield anti-glare film to cut down on reflections during long sessions. ASUS lists a 0.03ms response time and 1800-nit peak brightness for this pair, figures that sit only marginally behind the flagship model despite the lower price positioning implied by their spec sheets.
Buyers weighing up OLED gaming monitors already have plenty of competition to consider, including Gigabyte’s own AORUS OLED gaming monitors, which have carved out a strong reputation among serious PC gamers chasing similar refresh-rate and response-time targets.
Triple-Mode 27-Inch Monitors Join the Range
Alongside the FullHD Ace monitors, ASUS is expanding its triple-mode display family with two 27-inch options that let owners toggle resolution and refresh rate rather than being locked to one fixed configuration. The ROG Strix XG27UCMG is the 4K model, switching between 4K at 240Hz, QHD at 400Hz, or FHD at 488Hz depending on what a game or task demands.
It covers 95 percent of the DCI-P3 colour gamut, carries DisplayHDR 400 certification, and includes a built-in KVM switch alongside USB-C connectivity with 15W of power delivery, a handy feature for anyone running a laptop and desktop from the same screen. The second model, the ROG Strix XG27ACNS, uses a Fast IPS panel and leans even further into raw speed, reaching QHD at 475Hz, FHD at 620Hz, or HD at 920Hz with a 0.3ms response time.
Both triple-mode monitors support ASUS DisplayWidget Center software and include hardware-assisted AI visual enhancements, though ASUS has not yet confirmed pricing or availability for either one.

Why This Matters for Esports Players and Buyers
Refresh rates in the 500Hz-plus range were a novelty just a couple of years ago. Now they are becoming a genuine category, and the PG259QWS Ace monitor’s PGL endorsement suggests ASUS wants that model recognised as the benchmark screen for competitive Counter-Strike specifically, not just another spec-sheet flex. Tournament organisers do not hand out that kind of validation lightly, since any visible input lag or ghosting during a broadcast Major would reflect badly on both the hardware maker and the event itself.
The two QD-OLED models fill a gap for players who want extreme speed without paying flagship prices, while the triple-mode 27-inch pair targets a different buyer altogether: someone who wants one monitor for both competitive shooters and slower, more detail-heavy games without swapping displays. That flexibility, paired with features like the KVM switch on the XG27UCMG, points to ASUS treating these launches as complementary rather than a simple refresh of last year’s range.
For anyone shopping ASUS ROG peripherals more broadly, the Ace naming now spans mice, keyboards, and monitors, including gear like the ROG Keris II Ace gaming mouse and the ROG Falchion Ace HFX keyboard, suggesting ASUS is building a recognisable esports-grade tier across its whole product stack rather than treating the monitor lineup in isolation. Full pricing and release timing for the QD-OLED and triple-mode models should follow closer to their Q4 launch window, and further detail is expected to appear on ASUS ROG’s official site as availability firms up.
