If you prioritize top-notch color accuracy, deep blacks, and excellent contrast for tasks like HDR video editing or high-end graphic design, consider the LG 27EP950 (W-OLED) despite its higher price. It's also suitable for casual gaming and good for media consumption. However, for an immersive wide-screen experience and a balance between productivity, casual gaming, and media consumption, the LG 34GN850B (IPS) offers a larger screen with a more wallet-friendly price. Its faster refresh rates also make it more suitable for competitive gaming, but it won't match the W-OLED in terms of image quality for professional color work. 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."
