If competitive gaming is your priority, the Asus PG34WCDM with its higher refresh rate and rapid response time could be the better choice, plus it's less expensive. However, if color accuracy is crucial for tasks like print photo editing or you need a higher-resolution screen for productivity, the ViewSonic XG321UG may be worth the extra investment. For immersive experiences in HDR gaming and media consumption, the Asus's OLED panel would offer deeper blacks and higher contrast, whereas the ViewSonic's strengths in color accuracy and static contrast appeal to professional photo and video editors. Keep in mind, the Asus might not be as suitable for productivity due to its lower brightness and resolution compared to the ViewSonic. Give Feedback
