1440p 240 Hz OLED gaming monitor

Its OLED panel delivers exceptional image quality, with 99 % coverage of the DCI-P3 color space and an impressive contrast ratio of 1 500 000:1. With deep blacks and vivid colors, this monitor equipped with HDR10 technology delivers a maximum brightness of 400 cd/m² for optimal visual immersion and an enhanced gaming experience. To let you play in the best conditions, the ASUS ROG Strix XG27AQDMESZ benefits from a 2.5K resolution, a high refresh rate of 240 Hz and an ultra-short response time of 0.03 ms.
Exceptional image quality
The ROG Strix OLED XG27AQDMESZ gaming monitor from 27 inches is equipped with a QD-OLED screen with a 240 Hz refresh rate, OLED Anti-flicker technology and a gray-to-gray (GTG) response time of 0,03 ms for immersive and fast-paced gaming. A large heat sink delivers exceptional cooling performance, while ASUS OLED Care functions reduce the risk of burn-in to ensure the longevity of the OLED panel. This ROG-exclusive panel offers deep black tones and sharp images in all lighting conditions, for exceptional visual experiences.
Play in 1440p at 240 Hz
ROG OLED technology gives you an edge over the competition, thanks to crisp 1440p images and ultra-smooth gameplay at an astonishing 240 Hz refresh rate. The extremely high contrast ratio offered by OLED technology guarantees deep blacks and vivid colors. In addition, the gray-to-gray (GTG) response time of 0.03 ms ensures extremely smooth, low-latency gameplay. These features make the XG27AQDMESZ an ideal tool for gaming, but also for professional video and photo editing. Finally, the XG27AQDMESZ features NVIDIA G-SYNC Compatible and AMD FreeSync Premium technologies, ensuring super-smooth, tear-free visuals with low latency.
ASUS OLED CARE
The customized passive heatsink of the XG27AQDMESZ prioritizes heat dissipation. In addition, the back of the monitor features superior air vents that significantly improve cooling and reduce the risk of burn-in. ASUS OLED Care provides pixel cleaning reminders, a screen saver, a screen shift function and much more to protect the OLED panel and ensure the screen's longevity. When enabled, the uniform brightness setting (a ROG exclusive) in the OSD menu lowers the maximum brightness to maintain consistent levels for better viewing, even when changing the size of bright white windows. It also makes marathon gaming sessions much easier on the eyes.
