If you prioritize a large ultra-wide display for an immersive gaming and media experience, the MSI MPG 491CQP with its OLED technology offers superior contrast and color performance. It's well-suited for HDR gaming and has brilliant brightness and color depth but is more costly. However, for a balanced mix of productivity and high-resolution gaming or media consumption, the Sony M9 offers a crisper text and image clarity due to its higher pixels per inch and is less expensive. The Sony M9 also has good color accuracy but it's not as strong in contrast or color volume as the MSI model. Give Feedback
