Key Features

34-Inch Tandem RGB QD-OLED Display
Advanced Tandem RGB QD-OLED technology provides excellent contrast, vivid color reproduction, and near-instant response for both gaming and creative workloads.

3440 × 1440 UWQHD Resolution
The 21:9 ultrawide resolution delivers an expansive field of view with significantly more horizontal workspace than conventional 16:9 displays.

1800R Curved Screen
The curved panel wraps naturally around your field of view for increased immersion in racing, simulation, RPG, action, and cinematic games.

Ultra-Fast 280Hz Refresh Rate
Refresh rates up to 280Hz provide exceptionally smooth motion for fast-paced competitive games.

0.03ms GtG Response Time
OLED's extremely fast pixel response minimizes ghosting and keeps high-speed motion clear.

RGB Stripe Pixel Technology

The XG34WCDMS uses an RGB Stripe subpixel arrangement designed to improve text clarity and fine-detail reproduction.

Compared with earlier QD-OLED subpixel layouts, the RGB Stripe structure helps provide:

• Sharper text edges
• More precise color reproduction
• Improved desktop readability
• Cleaner fine details
• Excellent gaming and productivity performance

BlackShield™ Anti-Reflection Film

ASUS BlackShield™ film improves both screen durability and perceived contrast.

ASUS states that BlackShield provides:

• Up to 2.5× improved scratch resistance compared with previous-generation QD-OLED panels
• Up to 40% improvement in perceived black levels in well-lit environments
• Reduced distracting reflections
• Deeper-looking blacks under ambient lighting

Specifications

HDR & OLED Performance

The XG34WCDMS combines OLED-level black performance with high HDR brightness.

Key visual specifications include:

• Up to 1300-nit HDR peak brightness
• 1,500,000:1 contrast ratio
• VESA DisplayHDR 500 True Black
• HDR10 support
• 99% DCI-P3 color gamut
• True 10-bit color
• Approximately 1.07 billion colors
• Delta E ≤ 2 color accuracy

Because OLED pixels can switch off individually, the display can produce exceptionally deep blacks without relying on a conventional backlight.

280Hz Competitive Gaming

The ultra-fast 280Hz refresh rate is ideal for:

• Counter-Strike 2
• Valorant
• Fortnite
• Apex Legends
• Call of Duty
• Overwatch
• Racing games
• Competitive esports

Combined with the 0.03ms GtG response time, the high refresh rate provides clear and responsive motion during fast gameplay.

Adaptive-Sync Gaming

The monitor supports:

• NVIDIA G-SYNC Compatible
• AMD FreeSync Premium Pro
• VESA AdaptiveSync Display 280Hz

These technologies synchronize the monitor's refresh rate with compatible GPU output to help reduce tearing, stuttering, and uneven frame delivery.

Extreme Low Motion Blur

ASUS Extreme Low Motion Blur technology helps reduce visible motion blur and ghosting for clearer fast-moving images.

Combined with OLED's naturally fast response time, it provides excellent motion clarity for competitive games.

ASUS OLED Care Pro

ASUS OLED Care Pro includes multiple technologies designed to help protect the OLED panel and reduce the risk of image retention or burn-in.

OLED protection functions can be configured through ASUS DisplayWidget Center.

Neo Proximity Sensor

The integrated Neo Proximity Sensor detects when the user moves away from the monitor.

When you leave your desk, the screen can automatically switch to a black image to help protect the OLED panel.

When you return, the display restores the image automatically.

Detection distance can also be customized.

Custom OLED Heatsink

ASUS equips the XG34WCDMS with a custom thermal solution designed to help control OLED operating temperatures.

Improved heat management helps support long-term panel reliability and consistent performance.

OLED Anti-Flicker

ASUS OLED Anti-Flicker technology is designed to reduce visible brightness fluctuations during variable-refresh-rate gaming.

This can help provide a more comfortable experience when frame rates fluctuate significantly.

Auto KVM

The integrated Auto KVM allows one compatible keyboard and mouse setup to control two connected computers.

This is especially useful when switching between:

• Gaming PC and laptop
• Work computer and personal PC
• Gaming and streaming systems
• Multiple productivity devices

Connectivity

USB-C Power Delivery: Up to 15W
