If you prioritize a wider screen and gaming, particularly with fast-moving visuals, the LG 34GN850B would be preferable due to its better refresh capabilities, suited for a smoother gaming experience. However, it's not the best choice for HDR gaming or high-end photo editing. Conversely, the LG DualUp 28MQ780 offers a unique aspect ratio and higher resolution, which might benefit productivity tasks like multitasking or text-heavy work, and it's better suited to digital photo editing with its color accuracy. Unfortunately, it does not excel in gaming due to lower refresh rates and is less suitable if you're interested in HDR content. Consider the kind of activities you'll prioritize to guide your choice.

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."
