If you're looking for exceptional contrast and color for HDR gaming and media, the Acer X34V with its QD-OLED panel would be an excellent choice. However, if color accuracy for print photo editing is crucial, the ViewSonic XG321UG with its IPS Mini LED display and higher resolution might be a better fit, despite its higher price. The Acer offers an ultrawide screen which is great for immersive gaming experiences but might not be as suitable for productivity due to its lower text clarity. For competitive gaming, the Acer's faster response time and higher refresh rate could provide a smoother experience. On the other hand, for general productivity tasks or if a sharper image is a priority, the ViewSonic's higher pixels per inch could be more beneficial. Give Feedback
