Pixel-Perfect Clarity
RGB Stripe Pixel OLED Technology
The ROG Swift OLED PG34WCDN uses a revolutionary RGB Stripe Pixel OLED sub-pixel arrangement that redefines visual clarity. Unlike traditional OLED structures that result in colour fringing in text, the stripe pixel arrangement delivers remarkably sharper text and exceptionally accurate colour reproduction, making it ideal for any task demanding precise visual fidelity.
Unprecedented Durability and Contrast
BlackShield™ Film
The panel of ROG Swift OLED PG34WCDN is fortified with BlackShield™, a cutting-edge film that significantly boosts panel durability and visual contrast.
Enhanced Scratch Resistance
BlackShield film increases the panel's hardness to offer 2.5X better scratch resistance versus previous-gen QD-OLED panels. This innovative layer provides peace of mind, ensuring the display remains protected from accidental abrasions during cleaning or handling, extending the monitor's lifespan.
Boosted Perceived Black Levels
BlackShield also boosts the perceived black level by up to 40% in well-lit environments, compared to previous-gen QD-OLED panels. This means you'll experience even deeper, richer blacks and an exceptional contrast ratio, delivering breathtaking gaming visuals and cinematic content, regardless of ambient lighting conditions.

Screen Protection
ASUS OLED Care Pro
New ASUS OLED Care Pro technology provides a full set of customisable monitor settings (Features may vary by model.) to protect and ensure the longevity of the OLED panel. Plus, it includes the new Neo Proximity Sensor designed to guard against panel 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 it instantly restores content when you return. Detection distance can be customised to suit your preference, ensuring maximum convenience and protection.
Note: For best results, please ensure the monitor sensor is clean and free from dust.
Pixel Cleaning
The screen recalibrates after the monitor has been active for several hours—a process (Do not unplug the power cord during the cleaning process.) that takes just a few minutes and activates automatically when the monitor is turned off.
Screen Move
Pixel locations are slightly shifted periodically to help prevent burn-in, with several selectable movement levels.
Boundary Detection
The Boundary Detection feature dynamically reduces pixel brightness along the boundaries of black bars onscreen, and also slightly shifts the pixel of the near borders.
Screen Saver
The screen dims automatically after two minutes of inactivity.
Logo Brightness Adjustment
Static onscreen logos are detected and their brightness is automatically reduced to correct for potential picture-quality issues.
Taskbar Detection
The brightness of the taskbar is reduced to avoid burn-in.
Outer Dimming Control
The brightest areas of the screen are automatically identified and adjusted.
Global Dimming Control
The overall brightness of the display is automatically adjusted to reduce the risk of burn-in.
Target Mode
The entire screen dims while a selected pinned window maintains its current brightness setting.
Designed to Last
ROG OLED monitors are engineered to deliver stunning visuals for years to come. An innovative custom heatsink and a unique internal airflow design improve cooling and reduce the risk of burn-in. Additionally, each ROG monitor comes with a three-year warranty.

New ROG OLED Anti-Flicker 2.0 technology minimises onscreen flicker. New ROG OLED Anti-Flicker 2.0 technology ensures up to 20% less onscreen flicker versus previous-generation panels, enabling comfortable gaming experiences.
Luminance Compensation Algorithm
An 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.
Refresh Rate Cap
This feature caps the monitor refresh rate to reduce onscreen flicker. The three presets (High / Mid / Off) each cover a wider refresh-rate range, to suit individual preferences.
DisplayWidget Center
DisplayWidget Center is 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. It also offers firmware update notifications and includes a direct update option. Plus, you can import or export display configurations for easy sharing.

Play Smarter with AI Assistant
The AI Assistant in PG34WCDN includes AI Visual, Dynamic Crosshair, and Dynamic Shadow Boost. These features leverage AI technology to help you practice more effectively to improve your skills.
Dynamic Crosshair
Dark areas of the scene are automatically enhanced, making it easier for you to spot enemies hiding in dim areas of the map.
Dynamic Shadow Boost
Dynamic Crosshair changes the crosshair colour to one that contrasts with the background, so it stands out for more accurate aim.
AI Visual
AI Visual automatically detects what's onscreen and adjusts to provide the best default or user-preset monitor settings through DisplayWidget Center (ASUS DisplayWidget Center software required.).
Uniform Brightness
When activated, the ROG-exclusive Uniform Brightness (When the monitor is in sRGB mode) 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 your eyes.
In-Game Enhancements
