I know this topic was discussed many times before all over the internet. however, rarely if at all I saw any reference on two uses cases that are in my interest. so i am hoping to get an answer here:\n\nUse case 1: Stereo 2.0 content with a 5.1\/7.1 speakers layout\nUse case 2: rather to use an upmix on 5.1 content in a 5.1 speaker layout.\n\n1. what’s different about Dolby Surround and Neural:X on my specific use case? i.e. Which one works better with Stereo 2.0 content with a 5.1\/7.1 speakers layout?\n\n2. if I have a 5.1 speaker layout, is there any added value using the Dolby Surround upmixer \/ DTS Neural:X upmixer for a 5.1 content (e.g. DD \/ DTS)?\nand if so , which one would most likely result best (5.1 content on 5.1 speaker layout with what upmix mode\/technology)? would it enhance anything?
