If you prioritize a wider screen and high peak brightness for a more immersive experience in HDR gaming and media consumption, the MSI MPG 491CQP (QD-OLED) with its impressive color gamut and contrast is a great choice and is less expensive than the AOC AG456UCZD (W-OLED). However, for the absolute best performance in competitive gaming, the AOC may be worth the higher cost with its superior refresh rate and response time. Both are excellent for color-critical tasks like photo editing, but the MSI has an edge in HDR video editing. For productivity and casual gaming, either monitor will perform well, but text clarity and image sharpness are not the strongest points for these types of OLED monitors. Give Feedback
