For example, just connect to my TV and then stream Netflix with 5.1 sound, or is there anything else to consider?
That's fine.
Of course you have to take a cable which supports that. Eg an optical
Okay, I have logically even inquired before. That means my TV needs either an optical connector or an HDMI with Arc support or are there other possibilities?
Often there's also a coaxial connection. Personally, I find the optical easiest.
One last question, then I would be happy, what exactly means if there's FullHD, or 4K upscaling? As I understand it means, but if I connect my ps4 pro for example to the receiver and then s.den TV is only a Full HD Receiver in 1080p. But I can also just connect the console s.den TV directly from the TV s.den receiver or not?
This means that if you connect a Full hd device to the Receiver and a 4K TV, he has then artificially trying to get to 4K (upscaling).
That may be true but the audio quality via HDMI is better.
You will hear 100% no difference. And you will not have any audio interruptions or interference
Yes, I hear that because I do not have the usual discount scrap and even the Yamaha will sound audibly better in direct comparison via HDMI. With a Bose it would not matter.
If you think.
