If you prioritize high-quality visuals and are engaged in HDR gaming or photo editing, the Cooler Master GZ2711 with its OLED technology provides exceptional contrast and color depth, but it comes at a higher price and isn't the best for tasks involving high brightness due to its poor peak brightness. On the other hand, the Lenovo G24-20 is more budget-friendly and still offers good color accuracy for print photo editing, with a decent refresh rate for casual gaming. However, its lower resolution and color performance aren't ideal for HDR gaming or media consumption, and its overall image clarity can't compete with the Cooler Master's OLED display. Give Feedback
