Fourth-Gen Tandem QD-OLED
What’s more, the ASUS ROG Strix QD-OLED XG27UQDMS 27" 4K Gaming Monitor utilises fourth-generation QD-OLED technology. This facilitates incredible colour fidelity, with a Delta E < 2>
To ensure the longevity of this display, the ASUS ROG Strix QD-OLED XG27UQDMS 27" 4K Gaming Monitor is equipped with premium ASUS OLED Care Pro. This suite of features includes a variety of tools to help prevent burn-in, keeping the screen factory fresh. The Neo Proximity Sensor detects whether you are at your screen or absent, automatically transitioning to a black screen when you are away. Pixel Cleaning recalibrates the display when the monitor has been active for a few hours, while Screen Move will shift the pixels periodically. For any displays with black boundaries, Boundary Detection dynamically detects these and reduces their brightness while shifting pixels near the border.
All these features are paired with a custom heatsink and internal airflow design, which work to keep the ASUS ROG Strix QD-OLED XG27UQDMS 27" 4K Gaming Monitor cool. Well maintained thermals also help to prevent burn-in.
Smooth Display
The ASUS ROG Strix QD-OLED XG27UQDMS 27" 4K Gaming Monitor is primed for gaming with stunning visuals. The 27” display has a QHD (2560x1440) resolution, providing optimal pixel density for crisp detail, clear UIs, and cinematic rendering. With a 240Hz refresh rate and 0.03ms response time, all visuals will be smooth, fluid, and responsive for heightened immersion.
What’s more, the ASUS ROG Strix QD-OLED XG32UQDMS 32" 4K Gaming Monitor features NVIDIA G-SYNC and AMD FreeSync Premium Pro support. These variable refresh rate technologies match the screen frame rate with your GPU output, resulting in reduced screen-tearing, ghosting, and stuttering. On top of this, ASUS Extreme Low Motion Blur (ELMB) technology works to minimise motion blur. Even when the action picks up, you can game with clarity!
Advanced Gaming
To optimise your experience, the ASUS ROG Strix QD-OLED XG27UQDMS 27" 4K Gaming Monitor employs a range of advanced gaming features. The ROG-exclusive OLED Anti-Flicker enables you to game with one of three refresh rate ranges, High, Mid, or Off. These actively reduce flicker during frame rate fluctuations, so you won’t be distracted during missions or cinematic scenes. With ROG Uniform Brightness, you can ensure the display is always at the most comfortable brightness for your current content.
For gamers who play a variety of genres and styles, the ASUS ROG QD-OLED XG32UQDMS 32" 4K Gaming Monitor has an adjustable aspect ratio. When playing competitively, you can simulate a 24.5” 240Hz esports display. Alternatively, there is a 4:3 mode with either a 1280x960 or 1024x768 resolution to utilise as your gameplay demands.
The ASUS ROG Strix QD-OLED XG27UQDMS 27" 4K Gaming Monitor also enables you to play smarter with AI-enhanced features, which help to boost your skills as much as visuals. Dynamic Crosshair provides a fixed, high-contrast point for improving aim, while Dynamic Shadow Boost enhances darker areas on screen. AI Visual detects what is currently onscreen and automatically optimises settings to suit.
DisplayWidget Center
To ensure the ASUS ROG Strix QD-OLED XG27UQDMS 27" 4K Gaming Monitor performs optimally, this monitor is supported by ASUS DisplayWidget Center. This easy-to-navigate UI provides access to a range of settings and tools to fine-tune your display and viewing experience. All OLED Care Pro features can be configured within this software, while the GameVisual and GamePlus tabs offer a myriad of tools to customise your gameplay settings.
Seamless Integration
To optimise connectivity with your gaming PC and consoles, the ASUS ROG Strix QD-OLED XG27UQDMS 27" 4K Gaming Monitor features both HDMI 2.1 and DisplayPort 1.4 (DSC) connectors. Plus, there is a USB hub and 3.5mm headphone jack to support peripherals as needed.
What’s more, the ASUS ROG Strix QD-OLED XG27UQDMS 27" 4K Gaming Monitor will seamlessly integrate with any gaming aesthetic, thanks to the bold ROG styling and compact design. The monitor stand is compact, optimising desk space. Plus, the stand can be height adjusted, while the display tilts, swivels, and pivots. As a result, this monitor can be properly aligned with the rest of your set-up for maximum comfort.
In addition to this, the ASUS ROG QD-OLED XG32UQDMS 32" 4K Gaming Monitor features a 1/4" tripod socket, making this display well-suited to streamer set-ups.
