If you're looking for an immersive experience with deep blacks for HDR gaming and media, the Gigabyte CO49DQ with its larger, wider screen and superior contrast will excel, but at a premium price and potentially less ideal for multitasking due to its aspect ratio. The LG 27GP850, on the other hand, offers a more traditional size and aspect ratio that's better suited for general productivity and casual gaming at a midrange price, with good color accuracy for digital photo editing—however, its lower contrast ratio means it won't perform as well in HDR content compared to the Gigabyte.

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."
