If your focus is on immersive gaming and a rich visual experience with deep blacks and vibrant colors, the Acer Predator X45 with its OLED panel excels, especially in darker environments. However, it's not as suitable for tasks that require maintaining consistent clarity and color accuracy, such as digital photo editing. The ViewSonic XG321UG, while more costly, offers higher resolution and is better suited for productivity and digital photo editing due to its clearer text and image quality. Choosing the Acer will save money, but consider the ViewSonic if you need a monitor for detailed creative work and are willing to invest for that purpose. Give Feedback
