Asus launches its 34-inch 360Hz Tandem QD-OLED gaming monitor in the US

Asus has released the ROG Swift OLED PG34WCDN, a 34-inch curved gaming monitor that updates its ultrawide lineup for 2026. First shown at CES earlier this year, the monitor is now available in the US for $1,299.

ROG Swift OLED PG34WCDN Specifications

The monitor comes with the latest Tandem RGB QD-OLED panel from Samsung. Instead of the triangular sub-pixel layout found on older QD-OLED displays, this monitor uses a standard RGB stripe arrangement.

This is a practical update because it helps fix the text fringing issues that often make OLEDs frustrating to use for regular desktop work and reading. The screen features a standard 1800R curve, a 3440 x 1440 resolution, a 360Hz refresh rate, and a 0.03ms response time.

Asus is also using a new anti-reflective coating it calls BlackShield film. The company says this makes the screen more resistant to scratches, but more importantly for daily use, it is designed to keep black levels looking dark in bright rooms. Older QD-OLED panels tend to look slightly purple when ambient light hits the screen, so this coating aims to reduce that effect. For HDR content, the monitor reaches a peak brightness of 1,300 nits and covers 99% of the DCI-P3 color space.

To help prevent OLED burn-in, Asus included a custom heatsink and a proximity sensor built into the monitor. If you get up and walk away from your desk, the sensor notices and turns the screen black to protect the panel, waking the display back up when you return.

The port selection covers the bases for a modern high-end setup. It includes DisplayPort 2.1a with 80Gbps of bandwidth, meaning it can run the full 1440p resolution at 360Hz without needing display stream compression.

You also get two HDMI 2.1 ports, a USB-A hub, and a USB-C port that handles video while providing 90W of power to charge a laptop. There is a built-in KVM switch as well, allowing you to share one keyboard and mouse between two computers.

In related news, AOC has recently unveiled a new 2K 425Hz Fast IPS gaming monitor, while LG has introduced an affordable 23.8-inch FHD monitor with a 144Hz refresh rate.
