If you prioritize top-notch color quality and deep blacks for HDR gaming and media, the MSI MAG 321UPX with its OLED panel excels, especially in dark rooms. However, it’s at a premium price and might not offer the best value for casual gaming or productivity. On the other hand, the Sony M9 is less expensive and offers a balance of good color accuracy and brightness, making it versatile for productivity and media consumption. It's a worthy choice if you're looking for solid performance across various uses without the higher cost of OLED technology. Give Feedback
