Dd+ will work even in normal hdmi arc connection ,only Dolby Atmos requires eARC/hdmi 2.1 portAnd nowadays I researched, DD plus also pass through via if the device have EaRC out. Other wise we get only Dolby digital audio. So guys if , who are interested in audio side, buy the TV with Earc HDMI port. (Note: in interest don't change your TV immediately. In future)
