Our Verdict
LG 27GL850-B/27GL83A-B
LG 27GP850-B/27GP83B-B
The LG 27GP850-B/27GP83B-B is better than the LG 27GL850-B/27GL83A-B, but the differences are minor and might not matter to everyone. The 27GP850-B has a slightly faster refresh rate, resulting in better motion handling and a touch less motion blur behind fast-moving objects. The 27GP850-B also has an optional black frame insertion feature, but most people won't use this when gaming anyway.
