If you prioritize an immersive gaming and media experience with deep blacks and vibrant colors, especially for HDR content, and don't mind spending more, the AOC PD49 with its larger screen and superior contrast could be worth the investment. However, if cost is a concern and you seek a more balanced monitor that still performs well in gaming and productivity with a decent color range for tasks like digital photo editing, the LG 27GP850 could be a more economical choice, though it won't match the AOC's performance in HDR gaming or media consumption.

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."
