If you prioritize exceptional contrast and color depth for HDR gaming and high-end photo editing, and are willing to invest in a premium-priced monitor, the Cooler Master GZ2711 with its OLED panel is an excellent choice. However, it's not suitable for tasks requiring peak brightness or a wide color volume. On the other hand, the LG 27GP83B is more budget-friendly and offers good performance for casual gaming, productive tasks, and some digital photo editing work, but it falls short in competitive gaming and is not ideal for HDR content. It's important to consider that the LG model also has a higher motion blur, which can impact fast-paced gaming. Give Feedback
