Overview

Performance and comfort with an ultra-wide curved OLED screen

Whether for gaming, multimedia or everyday use, the AOC AGON PRO AG346UCD monitor offers you excellent comfort. With its large 21:9 format curved OLED screen, maximum display frequency of 175 Hz and fast response time, it gives you the image quality and fluidity you need. What's more, this screen is HDR 400 certified and has a height-adjustable stand.

QD-OLED screen in 21:9 format

Thanks to QD-OLED technology, this AOC monitor offers both a crystal-clear display and stunning contrast with rich colours. What's more, the screen can get very bright without losing colour quality, so everything stands out even in well-lit rooms. Essentially, QD-OLED takes the best elements of OLED and makes them even better with Quantum Dots, giving you a particularly lifelike image. This OLED screen comes with a 3-year guarantee against marking.

With a resolution of 3440 x 1440, Wide Quad HD (WQHD) offers a high level of image quality and sharp images that reveal even the smallest details. The widescreen's 21:9 aspect ratio is perfect for watching movies in an expandable format or immersing yourself in the latest game. True 8-bit colour depth delivers a wide colour gamut for vivid, natural images.

Fluidity and responsiveness

This AGON PRO monitor has a refresh rate of 175 Hz (100 Hz via HDMI). Low frame rates can cause screen tearing, input lag and make enemies appear to jump around, frustrating your gaming experience. A 175Hz frame rate delivers ultra-smooth movement, allowing you to see enemy movements, successfully track your targets and win the game (if you put your mind to it too).

Image enhancement features

DisplayHDR True Black 400 gives you deeper, more accurate black levels, making your viewing experience richer and more immersive. No more dark, washed-out scenes in movies and games. With TrueBlack400, you can embark on a more realistic visual journey.

Adaptive-Sync or FreeSync Premium Pro aligns your monitor's vertical refresh rate with the frame rate produced by your graphics card, giving you even smoother gaming or casual gaming by eliminating judder, spill and distortion. This function is also useful when watching videos or other visual media and provides optimised entertainment.

    A visual slap in the face without going overboard

    The AOC AGON PRO AG346UCD impressed me from the very first minute: the QD-OLED panel is sublime, with deep blacks and vibrant colours.
    When gaming, the 175Hz delivers exemplary fluidity, and the 21:9 aspect ratio makes everything more immersive - even the spreadsheet at work looks exciting.
    Ergonomics, design and connectivity are top-notch.
    In short, it's hard to find any real fault with it... apart from the fact that it spoils other screens. ??

    Aoc 34".

    I went from a basic curved screen to this monster.
    Beautiful colour, incredible brightness, a pure pleasure for my gaming sessions and my darling's teleworking.
