Description

The AOC AGON PRO AG346UCD is a 34-inch QD-OLED curved computer monitor with a native resolution of 3440 x 1440 (WQHD) and a 21:9 aspect ratio. Designed to deliver wide viewing angles of 178° horizontally and vertically, this monitor combines OLED contrast characteristics with quantum-dot color enhancement to provide vivid colors and deep blacks.

How to use

Connect the AG346UCD to your computer using a compatible video input and configure the display resolution to 3440 x 1440 in your operating system display settings. Use the on-screen menu to adjust brightness, contrast and color settings to your preference or to match a working color profile. Attach peripherals to the USB 3.2 Gen 1 hub for convenient connectivity and position the monitor on a desk or attach it to a VESA-compatible mount. Use the height adjustment to set an ergonomic viewing position and enable any available adaptive synchronization features on your GPU to minimize screen tearing.

Usage recommendations

For best results in color-critical workflows, allow the panel to warm up for a short time before final color grading and calibrate using a hardware colorimeter. In gaming, enable your GPU's adaptive sync and select the monitor's performance-oriented display mode to take advantage of the fast response time while keeping brightness and HDR settings balanced for eye comfort.
