Asus Rog Strix OLED XG27UCDMG - 27" - 240Hz Gaming Monitor

The ROG Strix OLED XG27UCDMG gaming monitor has been engineered for competitive gamers, content creators, and esports enthusiasts seeking ultra-fast performance and cinematic image quality. A 26.5-inch (27-inch class) 4K (3840 x 2160) QD-OLED panel is paired with a blazing 240Hz refresh rate and an ultra-responsive 0.03ms (GTG) response time, ensuring fluid motion clarity and razor-sharp detail. With 4th-generation QD-OLED technology, sharper text rendering and enhanced panel longevity are delivered compared to previous OLED generations, making it ideal for both high-performance gaming and professional creative workflows.

Outstanding HDR visuals are achieved through VESA DisplayHDR™ 400 True Black certification, peak brightness up to 1,000 nits (HDR), 99% DCI-P3 color gamut coverage, and true 10-bit color depth. Color accuracy with Delta E < 2 ensures precise reproduction for photo editing, video production, and color-critical tasks. OLED Anti-Flicker 2.0 technology, combined with a new luminance compensation algorithm, reduces flicker by up to 20% over earlier panels for more comfortable long gaming sessions. Burn-in protection is supported through ASUS OLED Care Pro and the integrated Neo Proximity Sensor, which automatically switches the display to black when the user steps away.

Key Features 

4K 240Hz QD-OLED Performance
A 3840 x 2160 resolution is combined with a 240Hz refresh rate, delivering ultra-smooth gameplay and exceptional clarity. Fast-paced competitive titles benefit from minimal motion blur and ultra-low latency, while AAA games are displayed with immersive cinematic detail.

0.03ms (GTG) Response Time
An ultra-fast gray-to-gray response time reduces ghosting and smearing. Rapid transitions are rendered cleanly, giving players precise visual feedback in high-speed gaming scenarios.

4th-Gen QD-OLED Technology
Improved pixel structure and panel optimization result in sharper imagery, clearer text, and improved durability over earlier OLED generations. Deep blacks and infinite contrast are preserved for dramatic visual depth.

OLED Anti-Flicker 2.0
A newly developed luminance compensation algorithm minimizes brightness fluctuations. Viewing comfort is enhanced during extended sessions, reducing visual fatigue without compromising image quality.

ASUS OLED Care Pro with Neo Proximity Sensor
Burn-in prevention is reinforced through intelligent monitoring features. When absence is detected, the screen is automatically dimmed or turned black, reducing static image exposure and extending panel lifespan.

Professional-Grade Color Accuracy
With 99% DCI-P3, 145% sRGB, true 10-bit color, and Delta E < 2 accuracy, lifelike color reproduction is achieved. HDR10 support and VESA DisplayHDR 400 True Black certification ensure deep contrast and vibrant highlights.

Adaptive Sync Technologies
Support for FreeSync™ Premium Pro and G-SYNC® Compatible certification ensures tear-free, stutter-free gameplay across compatible GPUs, maintaining smooth frame delivery.

Extensive Connectivity
Versatile connectivity is provided through DisplayPort™ 1.4 DSC, dual HDMI® 2.1 ports, and USB-C® with DP Alt Mode and 90W Power Delivery. A built-in USB 3.2 hub, KVM switch, and earphone jack enhance multi-device productivity setups.

Ergonomic and Premium Design
Full ergonomic adjustments including tilt, swivel, pivot, and height adjustment allow personalized positioning. Aura Sync lighting, VESA wall-mount compatibility, and a tripod socket offer flexible installation options.
