If you're looking for an exceptional gaming experience and vibrant colors for HDR media, the MSI MPG 321URX (QD-OLED) is a strong choice, with its OLED technology providing deep blacks and high contrast. It's suitable for both HDR gaming and various color-critical tasks, like photo editing. However, for fast-paced games, it may not be as suitable due to potential ghosting. On the other hand, the ViewSonic XG321UG (IPS Mini LED) offers a stable picture and is better for productivity with less ghosting, but it does not perform as well for color-critical work and HDR content. If your budget allows and your focus is on productivity and casual gaming with some photo editing, consider the ViewSonic, but if you prioritize high-quality imaging and vibrant HDR gaming, the MSI is a more cost-effective option.
