4k Upscaling vs Passthrough
Hey guy's, first post on the forum. I'll try to make a long story short. I'm about to purchase a 4k ultra tv, specifically from samsung UN65HU9000. Looking to buy a new receiver to match up with my 4k tv, but somewhat confused on something. I'm noticing some receivers say they have 4k passthrough, and others having passthrough and 4k upscaling together. I've done some research on the web, reading articles and even some posts on the avs forum and still confused on exactly what the difference is between them both and if i need one of them in my receiver, or both features in my receiver to pair with my 4k tv.
I'm aware that some of new receivers this year have HDMI 2.0, which I will definitely make sure the receiver I eventually purchase has it. But as i read the specs of some of these new receivers, some of them have 4k passthrough only, while others have 4k passthrough and upscaling. I'm very confused if my receiver need one of them, or both.
From my understanding, 4k tv's have the ability to upscale, so why would my receiver need to have 4k upscaling if the tv already does it...If so, then I would assume 4k passthrough is only necessary to pass the native 4k content to my tv, while my tv does the job of upscaling. That would lead me to believe you only need a receiver with 4k passthrough only.
Then i was thinking what if I get a receiver that has the capability of doing 4k passthrough and upscaling at the same time. If my 4k tv already does the upscaling, and a receiver does it as well, I'm worried that the video transfer will be messed up because the receiver and my tv is upscaling at the same time. Again, this is scrambling my mind to no end lol.
Sorry for the long post guys, i'm just really confused on this certain feature and just wanna make sure i'm well informed to make the right purchase for my receiver. 4k is new, so I guess we're all in the same boat. Looking forward to hearing what you guy's think and to get some concrete information about this issue. Thank You.
