If you prioritize a high-contrast display with vibrant colors for HDR gaming and media consumption, the MSI MAG 321UPX with its OLED technology offers best-in-class contrast and color volume, making it a compelling choice despite its poorer pixels per inch and ghosting performance. Conversely, if your focus is on digital photo editing and print photo editing where color accuracy is critical, the ViewSonic XG321UG's strength lies in its suitability for these tasks with its accurate color reproduction. The MSI is more suited for gaming and entertainment, while the ViewSonic offers advantages for creative professionals, though it does come at a higher cost. Give Feedback
