4K On An Old Receiver?

6685 Views 9 Replies 6 Participants Last post by  jon512
My old Yamaha RX-V575 is still going strong, but the devices around it have upgraded. I have media players and a TV that support 4K at 60Hz and HDR.

Is there a firmware update that can make this old Yamaha passthrough ultra HD 4K with HDR, or is it best to buy a new one? Surprisingly, the manual actually says 4K compatibility but only at 30Hz, no mention of HDR which did not exist when this receiver was made, but I hope there's a software update so I don't have to spend hundreds just to get full 4K passthrough.

Unfortunately no, the 4k mentioned is faux 4k, a way to do 4k over HDMI 1.4. At this rate, you can potentially rely on ARC if you have a compatible tv, or an HDFury AVR key which splits a 4kmsignal into one for your tv and one for your receiver. But you're also looking at $150 or so.

The other option is to get a 4k splitter and send the audio to the receiver and the 4k video directly to the projector bypassing the HDMI 1.4 limitations.
This switch should work It has 4 inputs and 2 outputs. One you can use for sound to the old receiver the other to the video display. You also have EDID settings to change if you run into issues.

Thanks, worf and rwestley!

Yes, this is a great idea and much cheaper than buying a new receiver!

If this thing splits 4K 60Hz HDR with 5.1 audio to 2 outputs (TV and receiver), will the receiver's HDMI 1.4 input be happy with pulling just the audio from an HDMI signal that includes a 4K video?

My player is an Nvidia Shield TV (2017), which supports Dolby AC3, Dolby ATMOS, Dolby TrueHD, and DTS X in passthrough mode via HDMI.

Only way to do it is to plug your device(s) directly into the TV, then run an optical cable from the TV to the AVR.
Either ARC or an optical cable but none will support lossless (Dolby true HD, DTS HD) preferably ARC as it should support DD+ where OPT won't. None of your streaming apps are better then DD+ lossey anyways. Only if you have locally stored lossless files will the Sheild play lossless so if that is the case only a splitter like an HDfury will work if you want lossless, better investment is an AVR upgrade in that case.

I totally agree that a new receiver would be a better investment than the HDfury. I suggested a switch/splitter as a way to use the old receiver even though you will not get losseless audio or Atmos.
On a 5.1 system, realizing the limitations, it is a low cost option.
This help has been amazing. Thanks.

I did not know about ARC. Since that has better support, I think I will try connecting my AVR to that.

My TV is wall-mounted with one old HDMI cable in the wall now, so I'll add an HDMI 2.0 cable in the wall. So I'll connect the Shield to the 4K HDR TV with HDMI 2.0, then ARC-HDMI to AVR. If I have issues, it's good to know that an HDMI splitter device is an option.

So happy there are cheaper options than buying a new AVR.
I recently went through this with my rx-a810 that was limited to 1080p. I replaced my plasma with a a9g oled. I was able to connect a 4k bluray player to the tv and use ARC to send sound to my old AVR. On my TV I had to make sure to set audio to passthrough for that input. An added bonus to ARC, you also get remote control through hdmi. The TV can turn on the AVR and adjust volume or control your bluray player.

I have sense upgraded the receiver to RX-A3070 that has 4k and eARC. I added 4 more speakers to get 7.2.2 and it is a world of difference. Start saving for a 9 or 11 channel AVR. Even 5.1 non Atmos movies sound much fully with Yamaha DSP.
ARC success! Surroundsound with 4K HDR.

I am having one minor issue. Audio works, then when I power off the TV or Shield then back on again, the AVR's audio does not come on even though the AVR is on and tuned to the correct input. Seems like no audio is reaching the AVR. I can get the audio back by changing the AVR's input to something else, then back to ARC, which seems to do some re-syncing and the audio signal comes back. Not sure if it's a Yamaha AVR issue or a ARC CRC problem with the TV, so I'm going to keep playing around with ARC and CEC settings on the TCL 55S405 Roku TV and Shield.

Anyway, ARC is working and now I have 4K HDR on the TV plus surroundsound on my old AVR. TV's volume does control the AVR's volume, which is nice.

Total investment was two new HDMI cables. I decided to remove the old HDMI 1.4 cable in the wall, and replaced it with two HDMI 2.0 cables and one Cat-6 ethernet cable. Shield's HDMI is connected directly to the TV, and the TV's ARC HDMI to the Yamaha AVR's ARC port which is its HDMI output port. Figured out to tune the TV to the ARC HDMI and use the on-screen controls of the Yamaha AVR to set up ARC mode. The Cat-6 cable is for the TV's ethernet for better remote control reliability & latency than wifi.
