If you prioritize a large, ultrawide screen for an immersive gaming or multimedia experience and don't mind a higher price, the AOC AG456UCZD could be a better choice. However, if you're looking for a solid all-around monitor with excellent color performance for tasks like photo editing, and you prefer saving money, the Pixio PX277 OLED Max would be a good option. Keep in mind, the Pixio could also offer a sharper image due to its smaller screen size with a similar resolution. For competitive gaming, both monitors have similar characteristics with very good refresh rates and response times. Give Feedback
