If you prioritize high refresh rates and value for money in a gaming monitor, the Acer X34V with its QD-OLED panel could be a great choice, particularly for immersive gaming and media consumption. It stands out in colors and contrast, making it also suitable for digital photo editing. On the other hand, if size is more important to you and you're willing to invest more, the AOC AG456UCZD's larger screen could enhance your gaming experience and is still suited for print photo editing, despite it not offering the same value in other aspects compared to the Acer. Both monitors have a wide color gamut and high contrast, essential for rich, detailed images, but the Acer may offer a better overall balance of price and performance. Give Feedback
