If image clarity and digital photo editing are your priorities, the LG UltraFine 5K with its higher resolution and superior color accuracy is an excellent choice, especially for tasks that benefit from a larger screen and increased pixel density. However, if you're into competitive gaming, the ViewSonic XG2431 offers a faster refresh rate and features like VRR range and strobing, which can significantly enhance your gaming experience, though at a lower resolution. The LG will not be as suitable for high-speed gaming due to its lower refresh rate and response time. In terms of price, the LG is a significant investment compared to the ViewSonic, which offers fewer premium features but may provide better value for those focused on gaming or with a tighter budget.
