ASUS releases 34-inch 360Hz RGB stripe QD-OLED monitor in the US
ASUS has released the ROG Swift OLED PG34WCDN in the US. The monitor is now listed by Amazon for $1,299, months after its CES 2026 reveal.
The PG34WCDN is a 34-inch ultrawide OLED monitor with a 3440 × 1440 resolution, 21:9 aspect ratio and 1800R curve. It supports a 360Hz refresh rate and 0.03ms gray-to-gray response time.
34-inch Tandem RGB QD-OLED panel
The monitor uses Samsung Display’s newer 34-inch QD-OLED panel with an RGB stripe sub-pixel layout. Samsung calls this V-Stripe, while ASUS markets the display as Tandem RGB QD-OLED.
The panel change is aimed at reducing color fringing and improving text clarity compared to older QD-OLED monitors. Samsung Display started supplying this 34-inch 360Hz panel to ASUS, MSI and other monitor makers in late 2025.
ASUS also uses BlackShield film on this model. According to the company, the coating improves perceived black levels by up to 40% in bright rooms and offers 2.5 times better scratch resistance than previous QD-OLED panels.
The monitor supports VESA DisplayHDR 500 True Black, 99% DCI-P3 coverage, true 10-bit color and Delta E below 2 factory calibration. ASUS also lists OLED Care Pro, Neo Proximity Sensor and a custom heatsink.

For connectivity, the PG34WCDN includes DisplayPort 2.1a UHBR20 with 80 Gbps bandwidth , two HDMI 2.1 ports and USB-C with 90W Power Delivery. The monitor also has a USB hub, Auto KVM and a headphone output.
ASUS is not the only brand using this panel. MSI has the MPG 341CQR QD-OLED X36, while Gigabyte and Acer also announced 34-inch 360Hz QD-OLED monitors based on Samsung’s RGB stripe panel. For now, ASUS is among the first to bring its version to US retail.
