If you prioritize the highest quality image and colors for creative work or enjoy very high-contrast visuals for HDR gaming and media, the Cooler Master GZ2711 with its W-OLED panel will offer superior contrast and color depth. However, if you are more focused on a mix of competitive gaming and general productivity without a significant need for perfect blacks and wide color gamuts, the LG 27GP850 will provide good gaming performance due to its faster response times and adequate image quality at a lower cost. Keep in mind, though, the Cooler Master's OLED might suffer from image retention over time which is less of a concern with the LG's IPS panel. Give Feedback

Tim Schiesser | May 2021
"In my opinion, the LG 27GP850 is the best in its class from the monitors I've tested, with the combination of great response times and a functional sRGB mode pushing it over the edge. It's generally worth the price premium and its overall balance of features with few weak areas makes it a monitor you won't be disappointed to have."
