Seeking advice on how/where to set video parameter while watching 4K movie. As far as I know the setting can be found under Display tab in setting mode with just three picture to choose. Unfortunately video playback will stop whenever I enter the setting tab. What I really want is to set the video parameter on 'the fly' with the video playing. I will really like Zidoo to enable more setting like adding 'sharpness' setting. Thank you in advance for all the advice & guidance. Have a very nice day to all.
