Why is having an 8K receiver important??

Long story short. I recently upgraded my Pioneer receiver from a 2013 model to the 2019 model Pioneer SC-LX704. I also bought a new LG C1 OLED. I have it eARC to the receiver. So the TV handles the video portion(which it should) and the receiver handles the audio portion. Everything connected to the TV the sound will automatically be redirected to the receiver. So it begs to question. For what reason did I need to buy the 2021 model receiver with "8K"/HDMI 2.1 when the TV is handling the video part?? Not to mention 8K is in it's infancy and will be quickly obsolete like the first generation 4K was. I think many people overlook this and what eARC actually does. I just helped someone purchase a soundbar and he was clueless to what eARC is or 4K and 8K It's amazing how clueless the avg. joe ia and these companies take full advantage with buzz words like 8K, Atmos etc. So back to the purpose of this post. Why 8K receiver when you have eARC?

Well, I'm glad I posted this. I figured it would be a good conversation since. I didn't know about the DTS thing. I haven't had any issues at all with any bugs using eARC. Using the TV as the main hub has been very convenient especially with being able to use my TV remote for everything. I'll plug my 4K Blu-Ray back into the receiver again. So using Netflix through my TV I've missed out on DTS programs?

netflix doesn't use DTS. Most streaming services don't. It would be more for local content(rips or discs). And the TV can't pass lossless audio from 3rd party devices. It really depends on what you watch. Since lossless audio is very important to me and I make use of all audio formats the only option for me is to go through a receiver. And I avoid built in TV smart apps like the plague. They tend to be buggier and don't support everything I want to play and don't receive updates for quite as long as external devices. If you're needs are very basic then perhaps it won't matter to you.

Using my receiver and streaming devices I can still use one remote for everything. My ATV remote turns on the tv and receiver, controls volume, and turns it all off. Beyond initial configuration I haven't touched my tv remote since. No need.

Long as they remain backward-compatible, that’s all I care about. Because I’m certainly not going to go on that silly constant upgrade expenditure-chase. I’ll use my equipment til it dies, and only then consider whatever is the new tech of the moment.

For me it was being able to pass Dolby TrueHD Atmos via eARC for gaming. My Series X is directly connected to the tv because unfortunately eARC and full bandwidth 2.1 ports are separated on my TV.. Having this receiver also opens up in the future being able to directly connect the XSX directly to the receiver if need be. My previous receiver could not pass HDR10+, which was also important to me since my TV is capable and Prime Video on Fire Cube uses it, also I have several movies with HDR10+ on the disc. There is also my TV can't pass DTS-X.

I'd stick with your eARC receiver for now. The sad fact is, HDMI 2.1 is in it's infancy. High bandwidth consumer HDMI 2.1 devices (XSX,PS5, AMD/NVidia GPUs) didn't become available until late 2020. That means all 2021 TVs, receivers, etc were not stress-tested during the design phase with real-world devices. This is clearly evident from all the terrible bugs and hardware failures last year. EVERY manufacturer's receivers were broken until late 2021... even now, they only have 40Gb/s not the full 48Gb/s. TVs from every manufacturer had some kind of problem, VRR, audio pass through, game mode, etc.

2022 should be a MUCH better year for HDMI 2.1 devices, now that the sources have been available for testing and debugging for over a year. I suspect most TVs will be pretty bug-free this year. (Heck, Samsung and LG were pretty good last year) but receivers might not have 48Gb/s bug free units until 2023, they always lag behind.

I asked myself a similar question when I got my 4K TV a couple years ago, as the AVR (Denon 2200W) did not have any type of support for it. In the end, I’m happy with my old AVR despite an inconvenience around how the setup and options screens get displayed when I want to change settings. If I were to tweak settings more than I watch content on the TV, it would probably matter more.

With using music streaming apps on the TV (Sony Bravia 900H) vs others sources directly connected to the AVR (Amazon Fire TV 4K, the older AppleTV) or Pandora directly from the AVR, I like best the sound from the TV apps (Spotify, Pandora). YMMV. For other music streaming options, as well as direct use of my lossless audio content, I use a RasperryPI and a good DAC plugged directly in one of the RCA input ports of the AVR.

Your experience and preferences may differ from mine, as well as your own motivation for upgrading the AVR.

The Denon x2200W supports 4K 60hz as it is HDMI 2.0a and HDCP. 2.2 compliant. It also supports Dolby Atmos and DTS:X. I don't know if your unit needed a firmware update but it definitely supports 4K.

I think it's a little harsh to say "It's amazing how clueless the avg. joe is", the avg Joe has a flat screen and maybe a sound bar so 8K and all the other whizzbang buzz words mean nothing to him or her.

Here is another way to look at it. In a perfect world we have perfect information and the time to research it, unfortunately TIME IS EXPENSIVE, not everybody have the time to spend hours after hours in forums like this, so they overbuy for insurance, that's it. If you have the time and it's fun to learn all the ins-and-outs, by all means.

Would anyone with a A90J know what the best way to get HDMI 2.1 from tv from PS5 since I have a HTP-1 that doesn't have 2.1? Would I lose lossless formats if i do this?

many guidance is appreciated

Isn't your TV "only" 4k?


If so, then it really isn't important for you to have an 8k receiver.

I recommend not upgrading a receiver unless and until one needs something that the old receiver cannot do. Even if I had money to burn, I would do it that way, because I don't like bothering with hooking everything up to a new unit and redoing the setup.

You need to have a 2022 (2024) receiver because you want to pass every source through the receiver and receiver manufacturers cant be bothered to pass through the newest video formats correctly.

You need to have a 2022 (2024) tv because you want to pass every source through the tv and use eARC/ARC to pass audio to the receiver and tv manufacturers cant be bothered to pass through the newest audio formats correctly.

What, you want both audio and video with high quality, some future proofing and a low risk of bugs that will annoy you for the next 10 years? Sorry that cannot be done :) Perhaps in some alternate universe, every source will have two HDMI outputs, one for the tv and one for the receiver. The tv/receiver will have 3-10 inputs and we will glue together the two remotes to have simultaneous input switching. Even then I guess they will mess up lipsync...

My LG C9 is hooked up to my apple TV 4k directly (for Dolby HDR and 4k). My old Onkyo receiver is hooked up via ARC to the tv and the user experience is horrible. Popups about this and that, slow switching and generally unpredictable results. My family just watch movies on their iPads instead.

How about worrying about whether content achieves high quality, low or zero compression before worrying about the display system. In the days of CRT, I paid for cable which had HD 1080i and input that to my Sony Wega with 480 I inputs. There was a huge improvement by just upgrading the content. Today’s content still sucks compared to a 65 mm projection on the original IMAX.

Why 8K? Because the manufacturers have to put their children though college somehow...

I'll consider an 8K receiver after I install the rolled up 12' wide 16:9 native-LED 8K display that UPS delivers. Even then, I don't see any point in it since I don't sit 3' away from the screen. I guess if the display device ends up being capable of 8K, I'll match it with an apropriate reciever, but only then.... maybe.
