If you prioritize competitive gaming and require top-notch response times, the Acer X27U with its wider refresh rate and OLED panel is an excellent choice. However, the LG 34WQ73A offers a larger, ultrawide screen that's better for multitasking and productivity, albeit with a less suitable refresh rate for competitive gaming. For media consumption, the Acer’s better contrast and suitability for HDR will offer a more vibrant viewing experience, whereas the LG falls short in HDR performance. Keep in mind, the Acer's OLED could carry the risk of burn-in over long periods, which should be a consideration for static content. If budget is a concern, the LG provides a cost-effective solution, but for a premium gaming and cinematic experience, the Acer is superior. Give Feedback
