Our Verdict
LG 27GN850-B/27GN880-B
LG 27GP850-B/27GP83B-B
The LG 27GP850-B/27GP83B-B is a bit better than the LG 27GN850-B/27GN880-B. The 27GP850 has a higher refresh rate, resulting in a faster response time and clearer motion. The 27GP850 also has an optional black frame insertion feature to reduce the appearance of persistence blur, but it's a bit limited and only works over a narrow refresh rate range. Finally, the 27GP850 has slightly better connectivity, with a built-in USB hub.

LG 27GN850-B/27GN880-B vs LG 27GP850-B/27GP83B-B: Main Discussion
What do you think of these products? Let us know below.
Looking for a personalized buying advice from the RTINGS.com experts? Insiders have direct access to buying advice on our insider forum.
Hi, the LG 27GN850-B/27GN880-B was tested using our older 1.2 methodology, while the LG 27GP850-B/27GP83B-B was tested using our newer 2.0 methodology. Scores aren’t comparable between two monitors on different test benches, as we’ve updated the way we test significantly with 2.0.
The refresh rate on the 27GP850-B is higher but it has a significantly lower rating. Is this a mistake?
