ROG Strix OLED XG27UCDMG
The ROG Strix OLED XG27UCDMG is a 27-inch, 240Hz 4K gaming monitor that boasts the latest fourth-generation QD-OLED technology to deliver supersharp visuals and crisp text. The cutting-edge QD-OLED panel offers greater longevity compared to previous OLED technologies and minimal flicker-even when frame rates fluctuate. With the addition of the Neo Proximity Sensor in the new ROG OLED Care Pro suite, the monitor transitions to a black screen when no user is detected, guarding against burn-in.
Fourth-generation QD-OLED delivers richer colours, deeper blacks, and higher brightness, offering exceptional clarity and realism in every game or scene.
With 166 pixels per inch, the display produces crisp text and finely detailed visuals, making both gaming and everyday work look clean and precise.
OLED Anti-Flicker 2.0 reduces flicker by up to 20%, helping minimise eye strain during extended sessions while keeping images stable and consistent.
The panel’s ultra-fast pixel response eliminates blur and smear, ensuring moving objects remain sharp and defined even during fast-paced competitive gameplay.
Its 27-inch 4K screen balances size and detail perfectly, delivering sharp visuals with outstanding colour and clarity for gaming, media, and productivity.
A 240Hz refresh rate provides exceptionally smooth motion, giving competitive players faster visual feedback and an edge in high-speed action.
The near-instantaneous 0.03ms response time reduces ghosting and latency, delivering crystal-clear motion and responsive gameplay for demanding users.
A specialised heatsink efficiently dissipates heat, protecting the OLED panel, maintaining brightness, and extending performance during long gaming sessions.
OLED Care Pro applies smart protection features that reduce the risk of image retention, ensuring long-term panel health and consistent visual quality.
The Neo Proximity Sensor detects user presence, adjusting the display’s power states or brightness intelligently to save energy and protect the panel.
With 99% DCI-P3 coverage, the display produces vibrant, accurate colours suitable for gaming, content creation, and cinematic visual experiences.
Factory calibration ensures Delta E < 2 accuracy, delivering highly faithful colour reproduction ideal for designers and colour-critical work.
Adjustable HDR lets users fine-tune brightness and contrast levels, ensuring optimal HDR performance tailored to different games, movies, and environments.
True Black 400 certification provides stunning dark-scene performance, sharper contrast, and faithful HDR reproduction with exceptional shadow detail.
Uniform Brightness mode keeps the entire display evenly lit, preventing brightness fluctuations and ensuring stable visuals in any content.
DisplayWidget Center offers fast, intuitive access to monitor settings, allowing quick adjustments to colour, brightness, profiles, and system tools.
A comprehensive 3-year warranty ensures reliable support and protection, so users can enjoy premium OLED performance with greater confidence.
USB-C with 90W power delivery supports charging laptops, transferring video, and simplifying setups by reducing cable clutter and improving workflow.
Designed for discerning gamers and professional creators, it offers a refresh rate of 240Hz and 0.03ms grey-to-grey (GTG) response time for supersharp and fluid visuals.
Supersharp Imagery & Text
Experience exceptional clarity with the advanced QD-OLED panel, featuring a stunning 166ppi pixel density that delivers razor-sharp visuals and ultra-clear text for unmatched viewing precision.
Incredible Motion Clarity
ASUS Extreme Low Motion Blur technology delivers exceptionally sharp movement by minimising ghosting and reducing motion blur for smoother, more responsive gameplay.
Advantages of OLED Technology
ASUS OLED panels deliver exceptionally high contrast, producing deep, true blacks and brilliantly vivid colours for an immersive viewing experience—ideal for both gaming and creative work. With an ultra-fast 0.03 ms grey-to-grey response time, visuals remain incredibly smooth and responsive, ensuring low-latency performance even in fast-moving scenes.
New ROG OLED Anti-Flicker 2.0 technology minimizes onscreen flicker by up to 20% compared to previous-generation panels, enabling comfortable gaming experiences.
Luminance Compensation Algorithm
The advanced luminance compensation algorithm dynamically boosts pixel brightness during refresh rate fluctuations to ensure more consistent visuals without increasing input lag or compromising refresh rates.

Screen Protection
New ASUS OLED Care Pro technology provides a full set of customizable monitor settings to protect the OLED panel and ensure longevity. Plus, it includes the new Neo Proximity Sensor that detects your distance from the monitor and transitions to a black image when you’re away to safeguard the panel from burn-in. All settings can be easily managed via DisplayWidget Center.
Neo Proximity Sensor
The built-in Neo Proximity Sensor precisely detects your distance from the monitor. When you step away, the monitor transitions to a black image to protect against panel burn-in, and instantly restores onscreen content when you return. Detection distance can be customized to suit personal preference, ensuring maximum convenience and protection.
*Please ensure that the monitor sensor is properly angled and cleaned by using the included microfiber cloth before activating the detection function.
Automatically Transition to Black Image
Customise Detection Distance
Pixel cleaning
Recalibrates the screen when the monitor has been active for several hours-a process that takes just a few minutes and activates automatically when the monitor is turned off*
*Do not unplug the power cord during this time as it will interrupt the pixel-cleaning process.
SCREEN MOVE
Pixel locations are slightly shifted periodically to help prevent burn-in, and users can choose between several movement levels.
Boundary detection
Dynamically detects the boundary of the black bars and reduces the brightness and also slightly shifts the pixel of the near borders.
ROG OLED monitors are engineered to deliver stunning visuals for years to come. An innovative custom heatsink and a unique internal airflow improve cooling and reduce the risk of burn-in.
The XG27UCDMG monitor is a versatile powerhouse designed to excel in gaming, streaming, and content creation. Its high refresh rate, low response time, and vivid colours deliver a seamless, immersive experience. The wide viewing angles and built-in tripod socket make it perfect for streaming, while its exceptional colour accuracy and wide colour gamut ensure professional-grade content creation.

Content creation
The clean and elegant aesthetic of the XG27UCDMG underlines its premium status. There’s even a built-in tripod socket on top of the monitor to accommodate a camera for streaming setups.
The base has a small footprint to free up space for the keyboard and mouse. It also includes a mobile device groove to prop up phones.

Take your monitor to the next level with DisplayWidget Centre, a powerful monitor management software designed to help you optimise, personalise, and fully utilise your display via a mouse — so there’s no need to access the OSD menu. Additionally, DisplayWidget Centre notifies you of the latest firmware updates and includes a direct update option. You can also import or export display configurations for sharing.
The ROG Gaming AI technology in XG27UCDMG includes AI Visual, Dynamic Crosshair, and Dynamic Shadow Boost, leveraging AI technology to help you practice more effectively to improve your gaming experience.
Dynamic Crosshair
Automatically adjusts the crosshair to a contrasting colour based on the background, ensuring it remains clearly visible for more precise aiming.
Dynamic Shadow Boost
Automatically brightens darker areas of the scene, making it easier to spot enemies hiding in shadowy or dimly lit parts of the map.
AI Visual
Automatically analyses on-screen content and adjusts settings to deliver the most suitable default or user-defined visual mode via DisplayWidget Centre.
When activated, the ROG-exclusive Uniform Brightness* setting within the OSD menu decreases peak brightness to keep levels consistent for better viewing—even when changing the size of bright white windows. It also makes marathon gaming sessions much more comfortable on the eyes.

For competitive gamers who are more familiar with smaller 1080p monitors, the XG27UCDMG can display a 4:3 aspect image in 1280 x 960 or 1024 x 768 resolutions. Alternatively, users can play on a pixel-perfect 24.5-inch, 3552 x 1998 image at a native 240Hz refresh rate.
