If you prioritize competitive gaming and have a robust budget, the Acer Predator X45 with its higher refresh rate and very good response time offers an immersive, ultra-wide experience that will be advantageous for fast-paced games. However, its large size and lower resolution might not provide the best image clarity for productivity or media consumption. Conversely, the LG 27EQ850 boasts a higher resolution and excellent color accuracy, making it a strong option for digital photo editing, HDR video editing, and print photo editing. While its gaming performance is not as strong as the Acer, it's better suited for tasks where image detail and color representation are critical. Choose the Acer if gaming is your focus and you want a wider screen; opt for the LG if your work revolves around visual content and finer details are paramount. Give Feedback
