If immersive gaming and consuming HDR media are your priorities, the MSI MPG 321URX with its higher screen resolution and larger color gamut would serve you well, plus it's more suited to tasks like digital and print photo editing. On the other hand, if you're drawn to ultra-wide displays for an enveloping gaming or multitasking experience, and don't mind spending more, the AOC AG456UCZD may appeal to you with its 21:9 aspect ratio. Bear in mind, though, the MSI offers better overall contrast and brightness, enhancing its performance for varied media consumption. Give Feedback
