If you're looking for a monitor mainly for competitive gaming, the Acer XB323U-GX with its high refresh rate and very good response time will serve you well, but if you're into HDR gaming and media consumption, the AOC AG456UCZD with its OLED panel offers infinite contrast and exceptional color depth. The AOC's large, ultra-wide screen and resolution are great for immersive experiences and multitasking productivity, although its high price reflects that versatility. However, the Acer's smaller size and lower resolution might be more practical for everyday use and it's also very capable for digital photo editing due to its extensive color gamut coverage.
