If you're a professional in photography or video editing looking for top-notch color accuracy and deep blacks, the LG 27EP950 with its W-OLED panel excels, especially in HDR content, making it worth its higher price. Conversely, the ViewSonic XG321UG is a better fit if you're seeking a larger screen for productivity with a good balance for casual gaming and media consumption, and its IPS Mini LED panel provides a high contrast ratio with decent peak brightness for HDR, while being somewhat less expensive. However, for competitive gaming, neither of these monitors is ideal due to their moderate refresh rates and response times. Give Feedback
