If you're into competitive gaming, the Asus PG279QM with its higher refresh rate and faster response time will provide a smoother experience. On the other hand, if you prioritize high-resolution content and media consumption, the ViewSonic XG321UG offers better image clarity with its larger screen and higher resolution, but its lower refresh rate might not be as suitable for fast-paced games. For those involved in color-sensitive work, like photo editing, the ViewSonic with its higher color accuracy may be preferable despite the higher price. Both have good build quality with adjustable stands, but the choice ultimately depends on your primary use – gaming performance or image quality and resolution. Give Feedback
