If you prioritize competitive gaming and can afford a premium price, the Acer XB323U-GX offers a higher refresh rate and response time performance, which are crucial for fast-paced games. Additionally, it has wider color coverage, making it suitable for digital photo editing and print photo editing. However, if you prefer ultra-wide displays for an immersive media consumption and productivity experience, and are looking for a better value option, the LG 34GN850B is a 34-inch monitor with a 21:9 aspect ratio that offers good image clarity and a fair performance in casual gaming. Keep in mind, neither are ideal for HDR gaming or HDR video editing, as their peak brightness and contrast are not optimal for those uses. 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."
