I am looking for the PERFECT and FULLY OPTIMIZED picture settings for UHD 4K videos in general. It is a common issue that the blacks, especially in dark scenes/faces to not be distinct, and are thus blended too much into the dark, losing detail that should be in 4K. What are the settings to optimize and perfectly calibrate my Samsung UN55HU6840 for ALL material, so I do not have to keep adjusting and changing? This is supposed to be a so-called "Smart TV" afterall. Any suggestions are appreciated. If we had the not yet released 4K UHD blu ray players, we could have the 4K test and calibration discs. Doing it personally by eye is not optimal and you can have the settings not optimal.
