Our Verdict
Samsung Odyssey G5 C27G55T
LG 27GN800-B
The LG 27GN800-B is much better than the Samsung Odyssey G5 C27G55T overall. The LG has a much quicker response time, which results in a clearer image with less blur trail behind fast-moving objects. The LG has an IPS panel with wider viewing angles, making it better for sharing content or playing co-op games, but it isn't as ideal for dark rooms as the Samsung because it has a low contrast ratio that makes blacks appear gray.
