If you prioritize exceptional contrast and color depth for an immersive gaming and media experience and don't mind spending more, the Corsair 45WQHD240 offers these with its OLED panel. However, its image clarity and text quality are not optimal for productivity tasks. On the other hand, the LG 34GN850B offers a more affordable solution with an adjustable stand and decent performance for casual gaming and productivity. It doesn't excel in color accuracy or contrast for high-end HDR content like the Corsair does. If you're a competitive gamer or need excellent clarity for work and everyday use, the LG might suit you better, despite not being as vibrant as the Corsair for media consumption. 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."
