AOC AGP346UCSD: 34-inch QD-OLED with 360 Hz refresh rate and DisplayPort 2.1

Calendar 3/17/2026

AOC adds a new ultrawide monitor to its offering – the AGP346UCSD model (not to be confused with AG346UCD) from the AGON PRO series. The device utilises the latest generation of QD-OLED panel with a diagonal of 34 inches, offering a refresh rate of 360 Hz. This is a significant change in the 21:9 segment, where until now the market standard has been lower values. The monitor is equipped with DisplayPort 2.1 connectors and features that facilitate working on multiple devices simultaneously, such as a built-in KVM switch.

New QD-OLED V-STRIPE Matrix

The applied panel has a resolution of 3440 x 1440 px and a curvature of 1800R. It uses the fourth generation of QD-OLED technology with a V-Stripe RGB subpixel arrangement, which practically improves the readability of fonts and edge sharpness compared to older QD-OLED constructions with triangular subpixel arrangements. The response time of the matrix is 0.03 ms (GtG), and the peak brightness in HDR mode reaches 1300 nits (with 3% APL area).

The monitor has a VESA DisplayHDR True Black 500 certification and provides 99% coverage of the DCI-P3 colour gamut. The manufacturer claims a factory calibration level of Delta E < 1, which is an absolutely phenomenal result.

DisplayPort 2.1 Connectivity and Additional Features

In the connector section, we find DisplayPort 2.1 and HDMI 2.1. There is also a USB-C port with DP Alt mode, which allows for image transmission from a laptop while simultaneously charging (or rather maintaining battery) with a power of 15W. Thanks to the KVM feature and USB 3.2 hub, the user can control two computers using one mouse and keyboard.

The monitor casing, awarded the Red Dot distinction, features Light FX backlighting and an ergonomic stand with a height adjustment range of 150 mm. AOC has also added gaming-specific features such as a frame counter, on-screen crosshair, and a mode that enhances visibility in dark areas (Shadow Control). Inside the device, two 8W speakers have been installed.

What is the price?

The AGP346UCSD monitor has not yet been priced. However, it is assumed to cost around 1050-1300 USD (approximately 5000 PLN including VAT) at the time of launch. Currently, the product appears in the official catalogues of the manufacturer and will initially be available for sale in Asia. The equipment should be available in Polish distribution soon.
