If you're a serious gamer looking for a high-refresh-rate curved screen with exceptional contrast and color performance, the Corsair 45WQHD240 (W-OLED) might be worth the premium price. However, for tasks like productivity and digital photo editing, where color accuracy and crisp text are critical, the Dell U2723QE (IPS Black) provides good performance and value at an upper midrange price. The Dell's higher resolution lends itself to better image clarity, which can also be beneficial for media consumption, though it may not be as suitable for HDR gaming or as visually stunning as the Corsair. Choose the Corsair for high-end gaming or the Dell for diverse use including professional work. Give Feedback
