How to use a non-4k receiver with 4k TV???

Does anyone know how to only use the receiver as audio output (don't care for 4k) and use 4k inputs like Firestick or Google Chrome for the picture?

can the TV take in the picture and output surround sound signal via HDMI out to the receiver just for audio??

hdmi Splitter plug 1 into the tv and 1 into the receiver?
This is exactly what I am doing. My Sony has 4K passthough, but menus are all 1080p. So if you adjust the volume, the TV will switch to 1080p and then back to 4K.

Bought a splitter and done. No more resolution issues.

The only issue is that the splitter will only take 1 Input, and so can't have multiple Input Sources on one splitter

What I do is use my PS4 optical out to my old receiver, and the PS4 HDMI goes into my TV.

You are losing support for the "newer" (2006 or later) audio formats. Optical is limited DVD audio formats (Dolby Digital and DTS) but if you want BD audio formats (Dolby Digital TrueHD, Dolby Atmos, DTS-HD Master...) you will need to use HDMI.

As above. Optical bandwidth is too limited these days for the various new Dolby sound formats.

yeah I am aware of the limitations. Right now my system is still only setup as a true 5.1, so missing a few speakers anyway for the atmos, 7.2 or 11.2.1 or whatever the latest is.
The next big upgrade will be a current pre-pro, a 4k 120hz TV, and maybe a few more surround speakers.

Wow, using a PS4 as an HDMI to Optical convertor. Now that is RFD level frugality :D

Dolby TrueHD and DTS-HS Master Audio fully supports 5.1 so you would benefit from it. Atmos is for for "ceiling" speakers (the last digit in 7.2.4 for example) so you would not benefit from it in a 5.1 setup.

Plug an HDMI to the TV and to the ARC/EARC port of the receiver.

Plug the 4k firestick to any HDMI port of the TV. Set the audio on the FS (or whatever device) to pass through or HDMI.

It depends. Do you have ARC support on the receiver? Or is it too old for that?

This is exactly why ARC exists, but if your AVR is too old it won't support this. If the AVR has ARC the TV will be able to pass the audio from its input(s) back down the ARC input (which you'd connect your AVR to). But standard ARC is basically only S/PDIF-over-HDMI in implementation* meaning you would not be able to get higher res audio if applicable. eARC solves this problem but if your AVR had eARC it would definitely have 4K support so it almost certainly does not.

*Some TVs with only ARC (i.e. without eARC) can pass DD+ over the ARC connection; however, the AVR still would have to support it. There's no TVs that can do DTS-HD, TrueHD, or multi-PCM through standard ARC though, just not possible.

Your receiver has 4K passthrough though, OP's doesn't seem like it does. It's not able to accept or pass 4K at all. Anything handshaking with it will go down to 1080p. HDMI handshaking is based on lowest common denominator so even if you use a splitter, it should see the EDID of the receiver as not supporting 4K and then not outputting 4K regardless.

Nope, atleast on my splitter you can set the port to use. It's not a fancy one either - https://www.amazon.ca/gp/product/B0891L7XDH

You can set the port to use what?

The output device can only output one TMDS stream so even if you split it to two devices and could output the 4K signal, a receiver that doesn't support 4K at all will not receive any signal.

Edit: Okay so here's the thing, that's not a regular splitter. This is an active splitter and scaler. So what it's doing, for a device that doesn't support 4K is it's taking that 4K signal and downscaling it to 1080p (or whatever). The source still thinks it's outputting to only a 4K device, and it is only outputting 4K. It's the scaler (that's built-in), that's accomplishing this.

I wasn't aware that these were available this cheaply these days, as typically something that can do that and scales, is not so cheap. I imagine the downscaling is very basic but that's not really a concern.

Only thing I'm wondering is what happens to the audio in this case...can the lower res output from the scaler receive higher-res audio than the higher res output?

thanks! I will likely use ARC then. The TV and receiver both support ARC. Not looking for anything too fancy in terms of audio. I think DD+ is good enough for most case.

the smart TV will stream netflix, youtube, etc in 4k video and pass the audio to the receiver.

I am also looking to run some 4k movies downloaded - I suppose I can just transfer the file to a USB and plug the USB into the TV?

or I suppose I could connect the laptop to a splitter, 1 to the TV to power 4k, 1 to the receiver to power some HD audio?

Would be helpful to know the following:

1) Model of the Receiver
2) Model of the TV
16'x11' Living Room 11' Cathedral Ceiling. Hisense 65Q8G. Denon AVR-S740H 7.2 setup. Jamo Classic 10 280W Towers - FR+FL; Polk S35 - Center; Klipsch R51M - RR+RL; Klipsch R14M - Dolby FHR+FHL; Polk HTS10 Subwoofer x2. Unlocked Android Boxes from Taiwan x2

This is what I am doing with my FireStick. You can connect anything with HDMI to the input. This is the one I use, and due to it being an active splitter, can auto convert, etc - https://www.amazon.ca/gp/product/B0891L7XDH

All depends on your TV inputs and its capabilities.

1. Plug all your 4k devices into the TV.
2. Have your TV pass-through audio via optical cable.
3. Your non-4k receiver will be bottle necked with the audio optical cable and probably only getting DD/DTS 5.1

If you go with a 4k bluray player, the higher end models have 2 hdmi outputs, one for video and one dedicated for audio. This will allow you to max out your receiver capabilities decoding and possibly get DTS-MA Master Audio for 7.1 from 4k bluray discs. I don't know of any streaming service that does 7.1 or DTS-MA.

Don't ask how I know but it works and hopefully it helps a fellow RFDer.

During boxing week I bought a new 4k tv, but I couldn't find the receiver I wanted online. I ended up using my old onkyo hdmi 1.3 receiver. It was about 12 to 13 years old, bought it before 3d tv's even became a thing. Somehow it was still able to do 4k. You couldn't see the menu's on the tv (just on the reciever), but it was still able to decode the audio and send the video to the tv. I was kind of impressed. Downside was the ps5 couldn't support 120hz, but not many games use that.

I've demoted it to the TV in my office, but I thought it was pretty cool it somehow works with 4k60. I guess i'm saying it doesn't hurt to see what happens if you plug new hdmi stuff into an old hdmi receiver.

HDMI 1.3 doesn't support 4k, you need HDMI 1.4 or later.
Try not! Do or do not, there is no try...
