ASUS ROG Strix OLED XG27AQDMG Review: QHD, Glossy OLED, 240Hz, 0.03ms, 99% DCI-P3; A Brilliant, Glossy Victory

The ASUS ROG Strix OLED XG27AQDMG represents the latest evolution in gaming monitor technology, combining the stunning visual quality of OLED panels with high-refresh gaming performance. This 27-inch monitor targets competitive gamers and enthusiasts who demand the ultimate in color accuracy, contrast, and response times.

As part of ASUS’s Republic of Gamers (ROG) lineup, the XG27AQDMG features a glossy WOLED (White OLED) panel with Micro Lens Array+ (MLA+) technology, delivering exceptional brightness levels that rival more expensive QD-OLED displays.

With its 240Hz refresh rate and near-instantaneous response times, this monitor aims to satisfy the most demanding gaming scenarios while providing outstanding picture quality for media consumption.

Design and Build

The XG27AQDMG adopts ASUS’s signature ROG aesthetic, featuring a sleek black design with subtle RGB lighting elements on the rear panel.

The monitor strikes a balance between gaming-focused styling and professional appearance, making it suitable for both gaming setups and office environments.

Build quality is exceptional, with a robust construction that feels premium throughout. The monitor uses a flat stand design that provides excellent stability with minimal wobble when bumped.

A thoughtful addition is the smartphone groove integrated into the stand base, along with effective cable management routing through the stand itself.

The custom heatsink design is a standout feature, helping to manage the thermal characteristics of the OLED panel more effectively than many competitors. This engineering choice demonstrates ASUS’s attention to the long-term reliability concerns associated with OLED technology.

Display Quality

The heart of the XG27AQDMG is its 27-inch WOLED panel with MLA+ technology, delivering a native resolution of 2560 x 1440 pixels.

The display quality is nothing short of exceptional, with perfect blacks thanks to the self-emissive nature of OLED technology and a near-infinite contrast ratio that eliminates any blooming around bright objects.

Color reproduction is outstanding, covering 99% of the DCI-P3 color space and 135% of sRGB. The glossy finish enhances perceived sharpness and color vibrancy compared to matte alternatives, though it does require more consideration of ambient lighting conditions.

HDR performance is impressive for a WOLED panel, with peak brightness reaching over 1000 cd/m² for small highlights.

While larger highlights don’t maintain the same peak brightness due to OLED’s automatic brightness limiting, the overall HDR experience remains compelling.

SDR brightness reaches a respectable 267 cd/m², which is sufficient for most well-lit environments but may struggle against very intense glare.

The Uniform Brightness feature helps maintain consistent brightness levels regardless of content, addressing one of the common concerns with OLED displays.

Performance

Gaming performance is where the XG27AQDMG truly excels. The 240Hz refresh rate combined with a 0.03ms gray-to-gray response time delivers exceptionally smooth motion with virtually no blur or ghosting.

The near-instantaneous response time means the monitor can complete full color transitions before drawing the next frame, resulting in outstanding refresh rate compliance.

Input lag is impressively low across all refresh rates, measuring just 2.6ms at 240Hz, 6.3ms at 120Hz, and 14.1ms at 60Hz.

These figures ensure a responsive gaming experience whether you’re playing competitive esports titles or single-player adventures.

VRR (Variable Refresh Rate) support is comprehensive, with compatibility for NVIDIA G-SYNC, AMD FreeSync Premium, and HDMI Forum VRR. The VRR range extends from below 20Hz up to 240Hz over DisplayPort, providing smooth gameplay across a wide variety of frame rates.

Features

The XG27AQDMG incorporates several advanced features that enhance the gaming and viewing experience:

OLED Anti-flicker Technology: This proprietary feature addresses VRR flicker by constraining the refresh rate range. Users can choose between Strong (200-240Hz), Medium (160-240Hz), or Off (40-240Hz) settings, with stronger settings reducing flicker at the cost of some stuttering.

ASUS OLED Care: A comprehensive suite of burn-in protection features including pixel cleaning cycles, screen savers, and brightness limiters to help preserve panel longevity.

Custom Heatsink: Advanced thermal management system designed specifically for sustained OLED performance.

DisplayWidget Center: Software suite providing easy access to monitor settings and system information.

Gaming Features: As part of the Republic of Gamers line, the monitor comes with the expected gaming-centric software features.

These include Dynamic Shadow Boost, which brightens dark areas of a game to reveal hidden enemies without overexposing bright areas, multiple “GameVisual” presets for different genres, and ROG Gaming AI technology to enhance the user’s experience.

Black Frame Insertion: Optional BFI feature for reduced motion blur, though it’s limited to 120Hz operation.

The monitor also includes various screen protection features in the OSD, such as automatic pixel refresh, screen move, and brightness dimming to help mitigate burn-in risks during extended use.

Connectivity

• 1x DisplayPort 1.4 (240Hz, DSC required for 10-bit)
• 2x HDMI 2.0 (limited to 144Hz)
• 2x USB 3.2 Gen 1 Type-A
• 1x 3.5mm audio output

The lack of HDMI 2.1 is a notable limitation, restricting the monitor’s compatibility with newer gaming consoles and graphics cards that could benefit from higher bandwidth connections.

The HDMI 2.0 limitation means console gaming is restricted to 144Hz maximum refresh rates.

Ergonomics

Ergonomic adjustability is excellent, matching the high standards expected from ROG monitors. The stand provides:

• Height adjustment: 120mm range
• Tilt: -5° to +20°
• Swivel: ±45°
• Pivot: ±90°

All adjustments operate smoothly with appropriate resistance, allowing for precise positioning. The wide adjustment ranges make it easy to achieve optimal viewing angles for extended gaming sessions or sharing the display with others.

VESA 100x100mm mounting compatibility is included for users preferring aftermarket monitor arms or wall mounting solutions.

Comparisons

vs. LG 27GS95QE-B

Both monitors share similar 27-inch OLED specifications with 240Hz refresh rates, but differ in presentation. The ASUS features a glossy finish that enhances perceived image sharpness and color vibrancy, while the LG 27GS95QE-B uses a matte coating for better ambient light handling. The ASUS offers superior VRR flicker reduction through its Anti-flicker technology, though this can introduce some stuttering. Console compatibility favors the LG, particularly for Xbox Series X|S users.

vs. Dell Alienware AW2725DF

Dell Alienware AW2725DF offers a higher 360Hz refresh rate and QD-OLED panel technology, providing more vivid colors and slightly sharper text. However, the ASUS gets significantly brighter, making it more suitable for well-lit environments. The Dell’s QD-OLED panel can appear purple in bright ambient light, while the ASUS maintains true blacks. For competitive gaming, the Dell’s higher refresh rate provides an advantage, but the ASUS offers better overall versatility.

vs. MSI MPG 271QRX QD-OLED

MSI MPG 271QRX features QD-OLED technology with more saturated colors and a 360Hz refresh rate, making it ideal for competitive gaming with lower input lag. However, the ASUS provides superior brightness and better performance in ambient light conditions. The MSI’s QD-OLED panel suffers from the purple-black issue in bright rooms, while the ASUS maintains consistent black levels regardless of lighting conditions.
