If you're on a tighter budget and prioritize fast response times for competitive gaming, the LG 27GP850 provides a good balance at a midrange price. However, the MSI MAG 321UPX excels in color reproduction, contrast, and is superior for HDR gaming and media consumption due to its OLED technology, making it worth the premium cost for enthusiasts who also engage in digital photo and HDR video editing or enjoy watching movies in high quality. The larger screen and higher resolution of the MSI will also enhance productivity and media experiences, but the higher price might not be justifiable for casual use cases. Give Feedback

"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."
