If you're on a budget and primarily focused on productivity tasks such as office work or web browsing, the Dell S2721DS with its larger screen and higher resolution might be the better choice for you. However, if you're a competitive gamer looking for high refresh rates, snappy response times, and features like variable refresh rate (VRR) to minimize screen tearing, the ViewSonic XG2431 is suited for those needs despite the smaller size and lower resolution. Neither monitor is ideal for HDR gaming or professional photo and video editing due to their limited brightness and color gamut coverage. Give Feedback
