If competitive gaming is a priority and you prefer a wider, more immersive display, the AOC AG456UCZD with its higher refresh rate and excellent response time is a strong option. However, its image clarity and text quality are not as sharp, making it less ideal for productivity tasks. On the other hand, if you're focused on digital photo editing or want better image clarity and a higher resolution for productivity, the ViewSonic XG321UG would be more suitable, despite being more expensive. It won't match the AOC in gaming performance, but it offers a good balance for media consumption and creative work. Give Feedback
