He guys I have a question. I got new Samsung 8550 65 inch uhd. Also have a new Yamaha a/v reciever with 4k pass through. I have it hooked up this way and it works fine just want to know if I am loosing any video uhd hd quality? Satelite box is going straight to reciever, Blu-ray is straight to receiver. Then though the arc output from the reciever to the back of tv to the arc hdmi. THis way it looks great but just don't know if I should go sateite box straight to back of tv. And just have the reciever to arc....hence to separate hdmi instead of just the arc connection. Should I keep them separte or just use the arc for everything? THanks in advance. JB

You only need ARC if you are using the internal apps from the tv. Best and easiest way isIke you have it. Run all devices into your receiver and out to the tv.

Since the 1's and 0's in the HDMI Digital Stream are NOT being converted to a different resolution, the digital content is the SAME whether going thru AVR or NOT.

Wouldn't that depend on the AVR setting though? Some of the 4K AVRs will scale 720p and 1080i/p to 2160p which will change the resolution, and at that point the quality difference will be decided by whether the UHD TV or the AVR have the better upscaling implementation.

Upscaling vs Passthrough is usually a receiver option. I have my Onkyo set to pass through - but I know others have theirs set to convert to a fixed resolution.

So DON'T DO THAT....deinterleave, adaptive motion & other algorithms in UDTV can be designed with KNOWLEDGE of how the different algorithms interact within the particular design of the UDTV, which are NOT all the same.....
