If you're serious about competitive gaming and willing to invest more, the Asus PG279QM offers a higher refresh rate which is great for fast-paced games. However, if you prefer a wider screen for immersive gaming and multitasking, the LG 34GN850B's ultra-wide display at a lower cost may be more suitable, though its lower refresh rate could be less ideal for competitive gaming scenarios. Both are strong contenders for general productivity and casual gaming, but for tight budget considerations with a desire for a broader view, the LG might be the better choice. Give Feedback

"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."
