If competitive gaming is your priority, the Corsair Xeneon 27QHD240's very good refresh rate and response time offer an edge, plus it's less expensive than the LG. On the other hand, the LG 27EP950, with its higher screen resolution, delivers superior image clarity, making it better suited for tasks where detail is key, such as digital photo editing and enjoying 4K content. However, it falls short for gaming with a lower refresh rate. Consider how important gaming performance is versus visual fidelity and professional use when choosing, especially when price is a consideration. Give Feedback
