HDMI eARC connection test no.2 – LG TV, Denon AVR and Panasonic UHD BD

My second HDMI eARC test in which I am actually testing it in proper way. Test conducted with Denon AVR-X1600H A/V receiver, LG 55SM9000 TV and Panasonic DP-UB450 UHD BD player.

My first test (only ARC connection tested):

eARC stands for Enhanced Audio Return Channel and it is an improved version of the original Audio Return Channel introduced 10 years ago with HDMI 1.4. EARC is part of the most recent HDMI 2.1 standard. The main improvement is the ability for the TV to send out uncompressed 5.1 or 7.1 surround sound as well as high-bitrate and object-based formats like Dolby Atmos or DTS-X to the external device, using HDMI cable with Ethernet functionality.

    I have a question and I'm hoping you can help with your knowledge. I have a nanocell 90 which has eARC and I have a Yamaha rxv485. I have ultra high speed HDMI cable from tv eARC to receiver eARC but my problem come when I switch to just the Netflix app on the tv I get picture but no sound would you know how to fix this? Thanks in advance.

    Do you have to use an hdmi 2.1 cable to connect 2 earc device? My sony xh900 has 2.1 earc on port 3 and soundbar q70t soundbar has earc but i think no hdmi 2.1 so why need a 2.1 cable?

    Guys, anyone ever tried the LG's internal player with an ATMOS/DTS X movie on a USB HDD for this setup ?

    Can LG TV (SM9000 for example) passthrough the ATMOS/ DTS X signals to the AVR ?

    Any ideas ?

    Everything is Connected EArc or WHATEVER and Sounds and Picture Works Great, Just No TV Input Showing! YES I Did the Direct Connection From XBOX to TV and Yes I Seen it, But I Can't See it Through the Other Connections ,Like the Rest???

  5. Michael Burton

    Hey Can U or Someone Answer this 1! Why Can't I See the XBOX input on My LG CX TV Input, Like I Do All of My Other Devices ( Yes Everything is Connected to My X6400H Denon AVR But the Xbox Not Showing Despite All) on the LG CX Inputs

    this is all so confusing!
    I have LG CX OLED with Apple TV 4K hooked up to HDMI 1. I have Denon 4500H hooked up to eARC. With eARC turned on and streaming Atmos program from Netflix on the ATV, I see Dolby Atmos on the receiver, but only DD+ when streaming from the Disney + app. On the other hand I get Multi Channel audio from the inbuilt Netflix and Disney apps in the TV. With eARC turned on, I also get all sorts of cracks and pops as the source changes.
    If I turn eARC off, then I get DD+ across all apps internal and ATV and no cracks and pops. Really confusing

    Watching this in May 2020. I'm looking for a new TV as my 8 year old Pioneer Plasma 50" TV has, um, run out of plasma! 🙂 It comes on when it pleases, and not when I want it to! The 2019 and newer LG and Sony have eARC so I'm looking at those. Looks like the latest Samsung TVs do not have eARC. I'll be matching the TV I get with a Bose 500 Soundbar/subwoofer which features eARC. Have to wait and see what happens.

    Does Earc need hdmi 2.1 cable?

    Dear, does Earc demand hdmi 2.1 cable or it’s compatible with Hdmi 2.0.

    Is there any difference between a soundbar that already supports Earc and the soundbar that supports Earc after a firmware update from Arc to Earc?

    Is the earc a hardware or software issue?

    hey there, I can't set the receiver to get the audio from tv with hdmi. I use my pc on tv and it works fine but, if i open the apps (netflix/prime) on tv i don't have audio, just images. can you help me to set this config, please?

    This is awesome. Completely removes the need to use an AV Receiver as anything but an audio component. This means any receiver with eARC is future-proofed for the foreseeable future. We can simply use our TV for a component switch, bypassing all the complications we have with video and AV receivers.

  11. Lucky Luqa

    My tv has no eARC future but only ARC and planning to buy 4K passthrough soundbar with atmos and dtx.
    My question is if I will be able to enjoy atmos and dtx if I get this connected to av 4k reciver?
    Or there is any way around it?

  12. Sebastian Forero

    Thanks for The video, i wonder if are any changes with the latest LG TV Firmware updates, regarding The Transmission of lossless Audio formats in the in apps of theTV? DTS HD MA, Doldy True HD and others

    Hi I wonder if you can help me… I just bought a LG 86SM9070PUA Nano 9 Series 4K Ultra HD LED (2019) TV. I have a Denon X7200W receiver. My Sony 4K projector blew up from a lightning surge so I bought the TV – The projector worked great. Anyway, I have the TV connected through HDMI1. I get horrible signal transfer from the Denon to the LG. Sometimes it transfers a signal and accepts a source — sometimes it does not and just keeps the LG screen "No Signal". Any thoughts on how to make the handshake between changing sources from the Denon so there is no lag or no connection? If I fiddle enough back and forth from sources and go back to either CBL/TV or Media Player sources — it will finally work but — that's stupid. Help?

  14. Nick Morris

    Thanks for the test. Question: which app are you using to test the input signal to the AVR? Thanks Also, i see you are using an 18Gbps HDMI. Do you see any reason to go for a (more HDMI 2.1 compliant) 48 Gbps cable?

  15. Void Toast

    One other problem with LG 9 series eARC is that they do not support PCM 5.1/7.1 over eARC, this makes HD audio for games consoles useless as PCM 5.1/7.1 is their main output for games & the best quality you can get. If you connect to a receiver then you will lose VRR and ALLM rendering the whole point of eARC useless, really sloppy work on LG's part.

  16. NAGARAJ T.S.

    I appreciate your efforts. Keep going. Effect of these new format's, with old receiver only with arc maybe tested like this confirm when to upgrade to get benefits of new format's. And also is it worth to upgrade
