AOC Agon Pro AGP346UCSD arrives early in the US with $829 price
The ultrawide QD-OLED monitor is listed ahead of its Q3 European release schedule.
AOC’s Agon Pro AGP346UCSD is now available to order in the United States. The 34-inch ultrawide gaming monitor is listed on Amazon for $829.99. The first US deliveries are expected between May 29 and June 12 . The launch appears to be ahead of the European schedule. The monitor was previously listed for a Q3 2026 release in Europe at €899. The US listing means AOC has started selling the model internationally before that window.
The AGP346UCSD uses a 34-inch Samsung Display Penta Tandem QD-OLED panel with a 3440×1440 resolution, 21:9 aspect ratio and 1800R curve. It supports a 360Hz refresh rate and a 0.03 ms GtG response time. AOC also lists 300 nits SDR brightness and up to 1300 nits peak brightness in HDR mode.

Samsung Display introduced the Penta Tandem branding earlier this year for its five-layer QD-OLED stack. The company claims the newer panel design improves luminous efficiency by 1.3× and doubles lifespan compared with its previous four-layer QD-OLED panels. Samsung also lists up to 1300 nits peak brightness for monitor panels.
The monitor has DisplayPort 2.1 UHBR20, two HDMI 2.1 ports, USB-C with DisplayPort Alt Mode and 15W power delivery, three USB Type-A ports, a headphone jack and two 8W speakers. It also supports KVM, PiP and PbP modes.
This is another 34-inch 360Hz QD-OLED model based on Samsung’s newer ultrawide panel class. We previously covered Samsung Display shipping its 34-inch 21:9 360Hz QD-OLED panels to monitor makers including ASUS, MSI and Gigabyte. We also covered MSI’s MPG 341CQR QD-OLED X36 , another 34-inch 360Hz model using a five-layer Tandem OLED stack.
