If you're looking for an immersive ultra-wide gaming experience and prioritize an expansive field of view for productivity or cinematic gaming, the AOC AG456UCZD with its larger screen and aspect ratio could be the better choice, provided you're comfortable with a higher price. However, if you prefer sharper image quality, better accuracy for tasks like photo editing, and a more balanced choice for various uses including gaming, media consumption, and productivity at a lower price, the MSI MAG 321UPX would be the way to go. Both monitors have OLED panels which offer deep blacks and excellent contrast, but the MSI has superior brightness, making it more suitable for HDR content. Give Feedback
