If you prioritize a wider screen with an ultrawide aspect ratio at a lower cost, the LG 34GN850B might be your choice, suitable for immersive gaming and multitasking. However, it's not ideal for HDR gaming and media. On the other hand, the Sony M9 offers a higher resolution on a standard-sized screen with superior color performance and HDR capabilities, enhancing both productivity and media consumption, but this comes at a premium price. If high-fidelity color and HDR support are crucial for you, and budget is less of a concern, the Sony M9 should be your pick. 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."
