If you're mainly interested in HDR gaming and media consumption with outstanding color quality, either the MSI MPG 491CQP or the Samsung Odyssey OLED G9 would serve you well, as they offer excellent contrast and brightness, along with a wide color gamut. For fast-paced, competitive gaming, the Samsung has a higher refresh rate, which provides smoother motion, making it a better fit. However, for tasks that require image clarity and less ghosting, such as productivity, you might prefer the MSI monitor despite its lower refresh rate and longer response time. Both are premium-priced, large-screen, high-resolution choices, so consider whether the smoother gameplay experience of the Samsung justifies its typically slightly lower price compared to the MSI's performance in other areas.
