If your primary focus is competitive gaming with the best response times and refresh rates, the AOC AG276QZD with its OLED panel will excel, though it's a significant investment and less suited for productivity due to potential screen burn-in risks and smaller size. Conversely, the LG 34GN850B offers a wider screen and is more cost-effective, better for productivity and casual gaming with an expansive view but falls short in refresh rates and response times compared to the AOC, making it less ideal for competitive gaming. Neither is the best for HDR gaming and media consumption, although the AOC does hold an edge. Give Feedback

TechSpot
Tim Schiesser | August 2020
"Mid-range 3440 x 1440 144Hz VA monitors are ~$500 to $600 these days. You are getting a much better product for the higher price of the LG, with faster response times and better colors (outside of the contrast ratio), but this is definitely a monitor that is reserved for those that want the best of the best and are willing to pay for it."
