Immersive gaming experiences

The ROG Swift OLED PG34WCDM pushes the boundaries of gaming innovation with its 34-inch ultrawide 800R curved panel and superfast 240 Hz refresh rate and 0.03 ms GTG response time. Inside, a custom heatsink and improved airflow design help reduce operating temperatures and minimize the potential for burn-in to ensure the display’s longevity.
Third-generation ROG OLED technology enables the PG34WCDM to deliver 30% brighter imagery compared to previous models, and offers reduced red and green color fringing on text and lines, thanks to the Clear Pixel Edge algorithm. Plus, exclusive Extreme Low Motion Blur (ELMB) technology enables crisp, clear motion in the most fast-paced games.

User-friendly features

The ROG-exclusive uniform brightness feature allows for better viewing as it keeps brightness levels consistent ― even when changing the size of bright white windows. This feature makes marathon gaming sessions much more comfortable on the eyes.
The ROG Smart KVM software allows users to control two input devices with a single keyboard and mouse set. It even provides superfast USB 3.2 file transfers between input sources by allowing users to copy and paste, or drag files across the two devices. Additionally, extensive connectivity options including DisplayPort 1.4 with Display Stream Compression (DSC), HDMI 2.1, and USB-C with 90-watt Power Delivery make the PG34WCDM a versatile hub for gaming setups.
The inclusion of ASUS DisplayWidget Center software lets users easily change monitor settings and OLED Care functions via an intuitive interface using a mouse, without having to access the OSD menu.
