WQHD Gaming at 360Hz

The 3440 × 1440 ultrawide panel operates at up to 360Hz, delivering frequent image updates for fast-paced competitive gaming.

Combined with the OLED panel's 0.03ms GTG response time, the PG34WCDN is designed to deliver clear and responsive motion across its wide 21:9 field of view.

Tandem RGB QD-OLED Technology

The PG34WCDN uses a Tandem RGB QD-OLED panel with an RGB Stripe Pixel sub-pixel arrangement.

Unlike nonstandard OLED sub-pixel layouts that can introduce color fringing around fine text, the RGB stripe arrangement is designed to provide sharper text edges and more precise color reproduction.

360Hz

Ultra-high refresh rate for fluid competitive gaming across the 3440 × 1440 ultrawide panel.

0.03ms GTG

Near-instantaneous OLED pixel response for rapid transitions and high-motion gaming.

1800R Curve

The curved 34-inch 21:9 panel wraps the ultrawide image around the user's field of view.

BlackShield Film

The QD-OLED panel is protected by ASUS BlackShield film, which increases panel hardness to provide 2.5× greater scratch resistance compared with previous-generation QD-OLED panels.

BlackShield also improves perceived black levels by up to 40% in well-lit environments compared with previous-generation QD-OLED panels.

99% DCI-P3

Wide-gamut color coverage is combined with Delta E ≤ 2 color accuracy.

True 10-Bit Color

The panel displays approximately 1.0737 billion colors for smooth color gradation.

1,500,000:1 Contrast

The self-emissive QD-OLED panel provides high contrast and deep black reproduction.

Custom Heatsink & Internal Airflow

ASUS equips the PG34WCDN with a custom heatsink and internal airflow design to help manage heat generated by the OLED panel.

This thermal design works alongside ASUS OLED Care Pro to support long-term panel protection and reduce the risk of OLED burn-in.

ASUS OLED Care Pro

OLED Care Pro provides a collection of customizable panel-protection functions designed to reduce the risk of OLED burn-in.

Supported functions include Pixel Cleaning, Screen Move, Screen Saver, Logo Brightness Adjustment, Taskbar Detection, Boundary Detection, Outer Dimming Control, Global Dimming Control, and Target Mode.

DisplayPort 2.1a UHBR20 at 80Gbps

The PG34WCDN features DisplayPort 2.1a UHBR20 with full 80Gbps bandwidth, supporting WQHD at 360Hz without display-stream compression.

Two HDMI 2.1 FRL ports and USB-C with DisplayPort Alt Mode provide additional display connectivity, while USB-C also delivers up to 90W Power Delivery to compatible devices.

DisplayPort 2.1a

UHBR20 connectivity provides up to 80Gbps of DisplayPort bandwidth.

2 × HDMI 2.1

Dual HDMI 2.1 FRL inputs support compatible gaming and multimedia devices.

USB-C 90W PD
