Calibrating the picture using advanced settings is a somewhatt tiresome process, having to jump in and out of the adjustments to be able to see the full picture. The controlbars for contrast, light etc. are often covering the grayscale bars and other external reference images used for calibration. It would be very nice if the various controlbars were smaller, moveable and could easily be turned on and off. What I would prefer the most though, is the ability to adjust the advanced settings using the smartphone app "LG TV Plus", while showing the full picture without any annoying controlbars on screen. The settings for contrast, light etc. should only be displayed on the smartphone during adjustments.
