**ASUS ROG PG259QWS Ace is the first OLED monitor to run 720Hz at native 1080p; earlier OLED models reached it only at 1280×720. Samsung Display says it has a 4K 360Hz QD-OLED panel.**

ASUS Republic of Gamers announced on October 28, 2026 that the ROG Swift OLED PG259QWS Ace ($1,099) and the ROG Strix OLED XG259QWPG Ace ($699) are on sale, according to techtimes.com [1]. The PG259QWS Ace is described as the first gaming monitor to deliver 720Hz at native 1920×1080 on an OLED panel. Until now, 720Hz on OLED required dropping to 1280×720 [1]. European prices are €1,149 and €729 [1].

The PG259QWS Ace uses a 24.5-inch Tandem WOLED panel from LG Display. LG's own engineers had called exceeding 500Hz a "virtually unbreakable threshold" because picture quality falls sharply above it [1]. LG's answer is its Dynamic Frequency and Resolution (DFR) algorithm, which manages pixel addressing from panel design through the driver IC [1]. ASUS's earlier ROG Swift OLED PG27AQWP-W reached 720Hz only at 1280×720 [1].

## Tandem WOLED panel and interface

A Tandem WOLED stacks two complete emissive units in series, joined by a charge generation layer. Each unit carries half the load, so current density per layer is lower and the organic compounds age more slowly [1]. According to ASUS specifications, the design gives 31% higher brightness, 34% larger color volume and 63% longer lifespan than a conventional WOLED panel [1]. The monitor reaches 1,700 nits peak HDR brightness and carries a three-year burn-in warranty. A GaNFET-based thermal management system in the power electronics reduces heat in the driving circuitry [1].

The 720Hz mode needs DisplayPort 2.1 in UHBR20 mode, which provides 80 Gbps. An uncompressed 1920×1080 signal at 720Hz with 10-bit color needs roughly 25–30 Gbps [1]. HDMI 2.1 (48 Gbps) or an older DisplayPort standard will not give 720Hz at full quality. The 540Hz XG259QWPG Ace has no DisplayPort 2.1 [1].

## QD-OLED and WOLED compared

The monitor is only half of the chain: the PC must render 720 or more frames per second. In Counter-Strike 2 at 1920×1080 and low detail, current high-end GPUs can do that, while systems producing 200–400 fps will stay well below the limit [1]. Whether 720Hz gives a measurable advantage over 360Hz or 500Hz remains debated among display researchers and enthusiasts [1].

On the other side of the market, Samsung Display says it has built the first QD-OLED monitor panel combining 4K resolution with a 360Hz refresh rate [1]. QD-OLED uses a blue organic layer and a quantum dot layer that converts the light to red and green, so each pixel has three subpixels. WOLED uses a white organic layer under color filters with four subpixels: red, green, blue and white [1]. RTINGS reports that Tandem OLED arrived in late 2025 with a four-layer stack and still counts as a WOLED type [1].
