If you're on a budget and mostly into casual or competitive gaming, the LG 27GP850 with its higher refresh rate and quicker response time will provide a smooth experience. However, for the best in productivity and media consumption, especially if you're a prosumer or content creator who values image clarity and color accuracy, the Sony M9 with better HDR capability, higher resolution, and superior color performance would be a worthwhile investment despite the higher cost. Consider the LG 27GP850 if gaming is your priority or the Sony M9 if you need top-notch image quality and work with high-resolution content. 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."
