If you're a serious gamer, especially for immersive single-player games, the Acer X34V with its excellent contrast and brightness will provide a superior gaming and media experience, plus it's great for HDR content. Its wider screen and curve also offer a more enveloping experience for gaming and movie-watching. On the other hand, if your focus is on productivity, multitasking, and digital photo editing, the LG DualUp's unique screen offers more vertical space, which is beneficial for those purposes. Note that the LG DualUp is not suitable for HDR gaming or media consumption, which is where the Acer excels. Despite being less suited for competitive gaming due to its lower refresh rate, if gaming is not your priority, the LG might be the more cost-effective choice. Give Feedback
