“TruMotion, a feature used for motion smoothing, offers the usual soap opera effect-inducing settings plus a User option with separate De-Judder and De-Blur controls. The User mode also includes a Motion Pro setting that uses black frame insertion to reduce blur. While Motion Pro can be effective, it also serves to dramatically reduce picture brightness.
Image retention isn’t as significant a concern with OLED TVs as it had been with plasma and CRT models. (Image retention isn’t a problem at all with LCDs.) It can occur, however, so LG provides several features designed to reduce the risk. The most unique of these is a Logo Extraction Algorithm designed to slightly tone-down the brightness of stationary objects on otherwise moving images, such as scoreboards during baseball or football games. Its effectiveness appeared to vary with source material, but in my testing the decrease in brightness averaged about 40 percent.”
