If you prioritize high resolution and exceptional color performance for both gaming and media consumption, the MSI MPG 321URX (QD-OLED) stands out with its 4K display and superior contrast, making it great for HDR and color-critical work. However, if you need the higher refresh rates and features like strobing for competitive gaming, the Acer XB323U-GX (IPS) could be the better choice, despite being pricier. The MSI's strengths in image clarity and color volume also make it well suited for productivity and media, while the Acer may offer slightly better response times which is beneficial for fast-paced games.
