If you're looking for a monitor that excels in competitive gaming with a high refresh rate and lower response time, and you're okay with a lower resolution for a significantly lower price, the Acer XB323U-GX is a solid choice. However, if you prioritize image clarity, higher resolution, better performance in HDR video editing due to higher peak brightness, and are willing to pay a premium for it, the ViewSonic XG321UG would be more suitable. Keep in mind, the ViewSonic's refresh rate isn't as high as the Acer's, which may not be ideal for competitive gaming. Give Feedback
