If budget is a concern and you're focused on competitive gaming, the MSI MAG 271QPX with its excellent refresh rate is a more cost-effective choice while still delivering outstanding color and contrast. Conversely, if you're looking for an immersive experience in HDR gaming and media, and don't mind the investment, the Acer Predator X45 offers a larger screen size and state-of-the-art contrast, though it may not be as adept for tasks requiring sharp text quality due to its lower pixels per inch. Both monitors excel in color accuracy for photo editing, but for print photo editing, the Acer's larger color volume is advantageous. Give Feedback
