If you prioritize a premium gaming experience with excellent image clarity and performance in fast-paced games, the Asus PG34WCDM, despite its higher price, could be a great choice because of its superior contrast, brightness, and refresh rate. However, for general productivity and casual gaming, the Dell S2721DS offers a more budget-friendly option with good text quality and image clarity, although it does not support higher-end gaming features or HDR content as well as the Asus does. The Dell monitor also lacks an adjustable stand, which could be a consideration for ergonomic comfort during long work sessions. Give Feedback
