With the ASUS ROG Strix OLED XG259QWPG Ace, ASUS is raising the bar for e-sports monitors to a new level. Presented at COMPUTEX 2026 alongside the Edition 20, the new model combines a 24.5-inch OLED panel with an extremely high refresh rate of 540 Hz for the first time. Developed in close cooperation with professional tournament organizers such as BLAST and PGL, the monitor is clearly aimed at the competitive gaming sector. In addition to maximum speed, ASUS promises significant improvements in brightness, color reproduction and OLED longevity.
- World’s first 24.5-inch OLED monitor with 540 Hz
- TrueBlack Glossy Tandem WOLED panel with 0.02 ms response time
- Developed with feedback from BLAST and PGL
- DisplayHDR 600 True Black and 99.5% DCI-P3 color space coverage
ASUS ROG Strix OLED XG259QWPG Ace brings OLED technology to professional e-sports
The ASUS ROG Strix OLED XG259QWPG Ace marks an important step for the e-sports market. While OLED panels were previously mainly found in the high-end gaming and entertainment segment, ASUS is now bringing the technology to the professional competition monitor sector.
The centerpiece is a 24.5-inch TrueBlack Glossy Tandem WOLED panel with a Full HD resolution of 1920 x 1080 pixels. This resolution is still particularly useful in competitive gaming, as it enables the highest frame rates and minimizes GPU load.
The refresh rate of 540 Hz is particularly impressive, which, in combination with an extremely low response time of 0.02 milliseconds, should ensure maximum motion display. However, there is a small plausibility correction here: while ASUS officially states 0.02 ms, another source speaks of 0.2 ms. As modern OLED panels can already achieve response times in the 0.03 ms range, the lower figure seems technically plausible.
According to ASUS, the new Tandem WOLED technology should enable up to 15 percent higher peak brightness, 25 percent more color volume and a 60 percent longer lifespan compared to the previous generation. These values appear realistic, as tandem OLED structures actually offer efficiency and durability benefits thanks to their double emission layer.
The TrueBlack coating also improves the display of text and ensures sharper contrasts, a frequent criticism of previous OLED gaming monitors.
ASUS ROG Strix OLED XG259QWPG Ace focuses on uncompromising professional features
A decisive difference to classic gaming monitors lies in the consistent focus on everyday e-sports. ASUS has developed the ROG Strix OLED XG259QWPG Ace together with BLAST and PGL, integrating direct feedback from professional gamers.
One striking detail is the precise measurement markings on the stand and base. These make it possible to exactly reproduce monitor positions once they have been found – an important feature for tournament players who rely on consistent ergonomics.
There is also a new Quick OSD menu, which enables quick adjustments to important image parameters directly before matches. This is a practical advantage, especially in tournament situations where every second counts.
For players switching from classic TN panels to OLED, ASUS has integrated three special e-sports color modes. These should provide a familiar picture characteristic and make the switch easier.
The image quality is also impressive beyond the speed: the monitor meets the VESA DisplayHDR 600 True Black standard, covers 99.5 percent of the DCI-P3 color space and offers true 10-bit color depth with a color deviation of Delta E less than 2.
ASUS has not yet officially confirmed the price and market launch. However, in view of the technical features, the monitor should clearly position itself in the premium segment.
Conclusion
The ASUS ROG Strix OLED XG259QWPG Ace could change the e-sports monitor market forever. With 540 Hz, state-of-the-art tandem WOLED technology and targeted professional functions, ASUS is setting new standards for competitive gaming. The technical specifications seem plausible overall and show how strong OLED technology has become in the high-frequency range. Price and availability are still pending, but a market launch after COMPUTEX 2026 is considered likely.
