If you prioritize a larger screen for an immersive experience and are engaged in digital photo editing that benefits from a wide color gamut, the Acer XB323U-GX could be worth the higher price. However, if you're focused on competitive gaming and want to save money, the Asus PG279QM offers a high refresh rate and excellent responsiveness at a lower cost. Both have good color accuracy for casual content creation, but for HDR gaming and media consumption, they fall short compared to true HDR displays. The Acer’s broader connectivity might appeal if you have multiple peripherals, while the Asus is a more budget-friendly option for a smaller setup. Give Feedback
