Do I need 4K pass through?

[william273]

I had everything set up wrong but after talking with Samsung tech support it's working but I'm wondering if I need 4k pass through...the picture looks ok.

My tv is a 55 inch Samsung MU6300 4K TV...LG UP875 4K blu ray player and a Samsung HWR550 2.1 sound bar with rear speakers. The blu ray player is connected out from the HDMI to HDMI in on the sound bar and from the HDMI ARC from the sound bar to HDMI ARC on the TV. I'm just using the sound bar for watching movies on the blu ray player. I use the TV speakers when watching TV...I have no cable or Netflix so don't need the sound bar for TV...only for blu ray player.

I hear talk about losing resolution if you don't have 4k pass through but the picture still looks fine and I don't think any of this equipment has 4K pass through but it still looks 4k and not 1080...as far as I can tell. My concern is now I'm running my player straight to the sound bar instead of to the TV HDMI and was using optical from the player to the sound bar. Since everything is running to the sound bar via HDMI and ARC and ARC to TV...do I need to worry about 4K pass through or am I ok as is?
