If you're looking for an immersive gaming and media experience with deep blacks and wide color range, the Corsair may be worth the investment, especially if HDR content is important to you. However, it lacks the versatility for productivity tasks due to its poorer text quality and image clarity. On the other hand, the LG offers a solid gaming experience, adequate for casual and some competitive play, and its better text clarity makes it suitable for general productivity. It's also easier on the wallet, but it won't match the Corsair in terms of contrast and color vibrancy for HDR content. Choose the Corsair for top-tier gaming and watching movies, or the LG for a balance of gaming, daily tasks, and budget-friendliness. 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."
