![Roddy Ricch - Survivors Remorse [Official Music Video]](http://i.ytimg.com/vi/J5IeFzr2GgE/mqdefault.jpg)
Hey everyone! Hope this video was helpful! Remember, ARC and eARC are potentially helpful, but sometimes buggy, quirky in implementation. The key is to keep experimenting! Also, as another commenter pointed out, some TVs (like some Sony models) will get updates enabling eARC as an upgrade from ARC. The spec sheets online may or may not cover that. So check your TV’s audio menu for availability AFTER making sure you have the latest software and firmware updates!
I actually didn't think that the Samsung Q90R wasn't going to get an eARC update, but after following forums and anxiously awaiting, it finally happened.
one thing i am really wondering about as a gamer is input lag (not audio lag). Does hooking the console to the receiver (in my case a Vizio Atmos soundbar), then receiver to the TV,. introduce lag? Do you know anything about that? FWIW I can INSTANTLY tell when game mode isn't on my TV, so I am lag sensitive, and I didnt really notice any lag playing this way, but just want to be sure.
Anyways Finally got my setup working, it's a 2018 TCL 6 series (has regular arc, not earc) and a Series X and the Vizio Atmos bar. I had it wired as Xbox to TV, then TV Arc to soundbar. Wired this way, the Xbox doesn't even offer Atmos etc as options in it's audio output settings. Once I changed it to hooked the X to the soundbar, then the soundbar to the TV via arc, a whole bunch of audio settings on My Xbox including Atmos opened up, and trying with Halo Infinite seems to work great! Also, huge shoutout to MS, they have cool audio setup thing, that will individually fire each speaker in sequence along with a graphic where each speaker lights up as fired. Really cool to show noobs like me that it's working, and that all of my atmos speakers are firing! Fantastic little ease of use feature.
Kinda surprised Caleb that you didn't make any pithy comment about cables specifically marketed as ARC or eARC "certified".
@@burnsyd17 That’s a different video! You just have me a great idea, tho!
I still don’t understand why most tv’s, when supporting 4K120hz, have to include the ARC/eARC feature to one of those ports, such as the tcl 646. The only tv brand, that keeps it separate is the Vizio P series tv’s. I can only assume it’s a cost cutting measure since eARC is technically a 2.1 feature and they want to keep the price of the tv lower while still giving the option of having 4K120hz or eARC. Luckily, it appears the 2022 models are adding 2.1 to all available HDMI ports now, at least the higher end models. Hopefully, this is implemented more in upcoming tv’s.
This guy could easily give lectures in college. Thanks for clarity and level of information shared.
I believe the vast majority of the consumers DO NOT know about ARC and eARC. This is great information 👏
Thanks! I remember when we put out our first explainers on this tech, our headline was something like “the best feature you aren’t using.” I gather lots of folks still aren’t taking advantage.
@@Caleb_Denison they aren't using it because when people buy a TV they don't pay attention to the HDMI specs and only pay attention to size, and resolution. Everything else is an after thought. I don't know a single person in my family or friend group who knows what ARC or eARC is.
I'm mainly the tech heads like us that get into the weeds of specifications.
OMG, I thought you only did TV reviews, and I began looking for other stuff and you popped up !?!? You're style, knowledge, advice makes you my top reviewer on RUclips, hope you get that Million soon, keep up the good work :)
You created this video 48 hours before I needed it..amazing!
This is to be the best explanation on RUclips in example format, for different situations, for arc and e arc… EVER!
I do appreciate your time. Thank you so much for posting.
As other commenters have highlighted, this is an extremely informative and well presented piece. Well done, it helped me as just transitioning to ARC, and he did the best job of capturing subtle potential stumbling points; very succinct yet complete. Bravo.
The best person there is to explain all this confusion. Ty so much!
Great video! Just to clarify for your viewers, “compressed” and “lossy” are not the same thing. Dolby and DTS formats are compressed - TrueHD and DTSHD-MA are lossless (but still compressed). The only uncompressed mainstream format is PCM and LPCM.
Thanks for the clarification. I didn't know there was a difference.
Correct
He’s also wrong about the lag and lip sync with eArc. He’s right in the sense that those are quote on quote “advertised” features of eArc, however since the inception on eArc, certain and TV’s and devices, such as the infamous Xbox consoles and LG OLED TV’s are known to have significant issues with Dolby Atmos and lag/lip sync issues when using that with eArc.
@@TheLazyGamers LG TVs have issues with everything. Whenever I have to set up a Sonos Amp, Arc Soundbar or Playbar on one, it's always been a total clusterfuck. Samsung or Sony, no problems ever.
@@andrewbobucky4612 every TV has its pros and cons. The LG’s are the best when it comes to gaming features and having a high end panel, which for me are the biggest concerns.
My LG G2 can do 48Gbps HDMI 2.1 for 12-bit @ 120hz, and supports all video modes for my series X console without issues. For example Sony TV’s can’t do Dolby Vision @ 120hz, and also has increased latency at Dolby Vision 60hz due to not supporting a DV game mode. Sony TV’s also do not support LFC with their VRR unlike LG and Samsung, and due to not supporting LFC also doesn’t have Gsync nor Freesync Premium/Pro support.
With the Samsung’s they don’t support DV whatsoever so that’s a no go for my series X.
The G2 is the only TV on the market that supports all the HDMI 2.1 features and new console features (48gbps, 4K @ 120hz, VRR (Forum, Freesync Premium/Pro, Gsync) HDR (HDR10, Dolby Vision), ALLM and can reach 1000 nits HDR), and that’s why I chose it.
LG’s biggest issue has always been audio. The audio on their OLED’s is subpar as it is, plus the infamous e-arc bugs that plague the LG sets especially with gaming consoles just makes e arc completely useless on LG TV’s.
While the G2 supports all the picture settings for my gaming PC and series X console, it doesn’t support all the audio modes due to the removal of DTS/X over e-arc. So now I have to plug it into a soundbar directly in order to get all the series X audio formats. Only problem is there isn’t a single soundbar on the market that can do full 48gbps uncompressed, as well as passthrough 4K @ 120hz with HDR (Dolby Vision and HDR10), VRR (Forum, Freesync Premium/Pro, Gsync) and ALLM. The closest we get is the Sony HT7000, but that is limited to 40Gbps not 48gbps, as well as can’t passthrough VRR & ALLM.
At the end of the day, I wish there was a be all end all tv that just supported everything no questions asked, but unfortunately that’s not the world we live in and we have to pick our poison with TV manufactures accordingly. Hell the fact that we don’t even have viable hdmi 2.1 soundbars yet means I’m just gonna have to play the waiting game for the manufactures to step up their game.
This is by far the most simplified explanation on RUclips. It gave me exactly what I needed to know. THANK YOU! +1 sub
This video finally answered all my questions on why my receiver without earc isn't working right so thank you. I've searched for a lot and this is the first video that made sense
Glad we could help!
Thanks for keeping the explanation simple and clear.
Thank you for a very comprehensive tutorial!!!
that was a great video Caleb. you explained everything perfectly. very clear and concise 👍
This is a great video. Will be receiving my first smart TV in a couple of days and wanted to learn how to connect so that I could use both soundbar and TV speaker audio. Thank you for posting!
Thank you very much for your explanation, I have never really thought about this before.
But it's quite relevant to me because I thought I would have to buy a new surround sound system when i upgrade my TV because my current Receiver does not have HDMI2.1. But thanks to ARC and your explanation I now know that I do not have to do that at all.
Earc is still really good compared to arc to remove lip sync issues, or audio delay if you play games
Thanks for doing this. Glad to know I'm not alone on the imperfections.
Awsome video, thanks. Getting a Sound-System for my TV this-weekend. Now, I know what to look for!
Thank you. My system is amazing now. ARC rocks!
Hi Caleb ! love your videos, they are educational and entertaining !
I'm looking to buy a soundbar with only one Hdmi and I was worried I would not be able to use it with my Bluray player or PS5. This guy has saved my ignorant ass again. Thank you!
Thanks, this was extremely helpful in eliminating the lip-sync problem I was having with my Apple tvk and two home pod minis for better sound. Great.
Thank you for the understandable explanation. Very clear and helpful!
This was very helpful, thanks. Your videos are very insightful and I look forward to seeing all that you have to offer with your knowledge. This ARC/eARC video was actually a timely video because I have the Samsung Q90R 82"TV that I purchased 2 years ago and a remarkable think just happened: I just got firmware update that added eARC to my TV! As I'm sure you are aware, that this set didn't have eARC at the start, but now that limitation has been eliminated. I'm gonna go thru everything on my set to see how well it works but with your video, this will answer any questions I initially had about the differences. Thanks again!
Great information, period. No one else has suggested that we confirm that the TV supports sending Dolby ATMOS or DTS X via the ARC or ARC e port. And if not, to connect all of the other HDMI cables directly to the AV receiver. Thank you!
Thanks Caleb...great clarity on something I have, but had no idea what or how it was or worked!
Clear and informative as always.
Thanks for the straight forward info. Much appreciated!
Thank you thank you. Finally someone explained why my tv remote isn’t controlling my sound bar!
Always great to start my Friday by watching your new video :D
Great comprehensive review. ⭐️⭐️⭐️⭐️
Many thanks, Caleb. You're the best and always awesome! You made everything easy to understand the differences of these things.
Hello from Canada. Thanks for posting the very informative video.
I just got a 5.1 soundbar system that supports eARC as does my recently purchased tv. It is my understanding that I need an HDMI cable that supports HDMI 2.1 in order to get the most benefit from these systems. I ordered one on Amazon today and am using the regular HDMI cable that I already had until the 2.1 cable comes in. Thanks for the video, it helped a lot!
You do not need an HDMI 2.1 Cable to use eARC (HDMI 1.4 or better is fine), but if you are passing video through your soundbar you want to use a cable good enough for the video source. (HDMI 1.4 for switch and PS4/Xbox One, HDMI 2.0 for Apple TV/PS4 Pro/Xbox One X/Fire Stick, HDMI 2.1 for PC and PS5/Xbox Series)
Thanks for the explanation. I guess I sort of knew why to use it but did not fully understand. I have the same problem with the amplifier turning back on sometimes, but I found that using one remote over another turns it off with no problem.
Thanks mate. Clear and easy to understand
Thank you Sir!!! .. absolutely an outstanding technical video for not so technical people!!! .. 5 stars!!! .. now I know how to connect my PS5 to my new Samsung TV
Always helpful pro stuff, well done, excellent totorial, subscribed !
So many answers to questions I had. Thank you!!!
I have a 2008 Panasonic tv and I was pleasantly surprised when I connected a Chromecast dongle and the TV remote simulated the Chromecast remote and allows me to navigate the Chromecast menus and control all apps like Netflix. It also controls my receiver and DVD player…. Very impressed with my 14 year old plasma TV tech!
I never thought of connecting all the cables to the TV, I have always plugged all the HDMI cables to the amp. What you say about eArc makes sense and I will give it a try.
Very well done. answers the question succinctly.
I miss the analog days and the programmable Harmony Remote. It was just flawless with my TV and audio components.
Excellent and clearly explained!
Just migrated from optical to arc after a recent tcl Roku tv update. Using a 10 year old Onkyo. Man, the step up from Dolby Digital to DD Plus was noticeable. I don't think my equipment supports earc, unfortunately. But man, I am glad to be done with that optical.
Saving the optical for emergencies like old consoles or whatever.
You know. In that drawer. You have one. With all the other things we KNOW we will need one day for no goddamn good reason but we know where we last had it! :)
That drawer with extra items. I have several. A multitude of cables including s-video. Also a stack of old equipment including a variety of switch boxes. Radio shack had optical switch boxes
I had multiple drawers like that over the years.
What button to push that is in front of my Onkyo to activate the ARC port ?
Hi Caleb.
Thanks for another useful video. 🙏🏻
Thanks for clarifying the difference of both.
Excellent explanation. Thank you very much.
I've been using EARC from my Sony tv to my Marantz av receiver for over a year. For the most part it works really well. It so nice to not dealing with switching inputs.
My LG C7 TV received the full HDMI 2.0 from the PS5 and using ARC to get surround sounds from my aging 2013 sound system which has like HDMI 1.4.
So glad they came out with not dealing with switching inputs.
@@zZiL341yRj736 are getting full DD+ or DTS from PS5? I an ARC 1.4 HDMI not taking the eARC DD+ DTS from the PS5
Well Presented, nicely done!
Been watching some of your old videos and damn you have lost a lot of weight! Keep up the great work 👍🏾
Looking forward to the A95K review
A very interesting explanation. I guess your viewers are not the typical tv watchers. Using the receiver or tv as the switching device has limits because there are not enough inputs so an hdmi switch is required. I still have s-video switch boxes that I use and DVD recorders do not have digital inputs. Normally when you turn off a receiver it stays off. I have a Panasonic CD changer that will turn on and start playing after a power failure. The solution has been to unplug it.
Thanks for helping me understand these things. I’m going to stick to having everything connected to my receiver though. I don’t wanna deal with a million cables going to my wall mount TV.
Thanks for the lesson. This fixed my issue.
Awesome! Great refresher!
Sir Your advice is priceless BUT Sir Your Beautiful voice is a very pleasant for my ears.
Good one! Thanks for posting!
This is great I finally upgraded my projector to 4k. I was dreading spending another $900 just for more 4k inputs. I’ll try using ARC, 🤞🏻
Thanks for the little tidbit about checking the manual, it'll come real handy when I actually able to doing this.
Glad to help!
Wow now I knew the difference with this feature
Super helpful video, Remember the day when it was yellow cable video, white and red for left/right channel audio? So simple. I recently tried hooking up a great Samsung plasma to a Samsung QQ990b and was having all sorts of trouble. The little tip here @6:38 looked for Anynet+ (which I'd glossed over because there was no explanation of what that did), enabled that and bingo!
This is good info I never knew about this very helpful
Insightful video with details that I wish were common knowledge years ago, as I jumped on the new format bandwagon too early. I have a Samsung Q9-fn TV and a Samsung HW-K950 Atmos soundbar, which were highly rated at the time, but the manuals had no mention of the lag and compression issues of using standard Arc. It makes for a hefty investment to upgrade both.
Hi, thank you for the information
Thanks for the clear explanation, keep it up.
Wow! Brilliant tutorial👍💚
Hey Caleb. Your mentioning of CEC helped me resolve an issue that I was having. I have an LG OLED55C1 tv with a Shaw cable box, Apple TV 4k and an LG 4k HD Bluray player all connected to hdmi ports on the TV. I decided to get an LG eclair QP95 sound bar for better sound especially since it supports Dolby ATMOS. The tv and the sound bar both have eARC so I have term connected to each other through eARC. The only issue is that when I power up the shaw cable box is that I don’t get audio for about 45 seconds and while I am waiting for the audio the screen blanks out 3 times and after the 3rd time I see a message at the bottom of the screen that says LG ready and then I get audio. I think that the Tv must be enumerating all of the HDMI devices. So after trying about 20 different settings, cables,ports, etc I decided to look for CEC settings on all of my devices. So first I checked my shaw cable box and found that CEC was enabled so I disabled it and suddenly it went from about 45 seconds and the screen blanking out 3 times before I got audio to 18 seconds and no screen blanking out to get audio. 😅Thanks for the videos!!
Thanks for the explanation appreciate it keep the videos coming.
Unfortunately arc earc stil don't work with my old Vizio Atmos 5.1.2 sound bar. Always have to unplug & replug HDMI cord after I turn the U7G on. Then mostly works all day. A few times the tv switches to tv speaker from arc/earc.
My new favorite AV channel 😊👍🏻
Thanks for your sharing
Your content is by far the most comprehensive, clear and easy to understand. Thanks for all of your hard work. I just bought the Sony A95k 65" and a Sonos arc sound system with a Gen3 Sub and 2 x one sl's for surrounds. I'm just wondering, do I need a special cable to carry the eARC signal from the TV to the ARC? or will any hdmi cable suffice? I'm about to get an installer to come wall mount it for me so I kind of need to get it right haha.
Great question, you need a "High speed HDMI Cable with Ethernet", but that's just about all cables made in the last 10 years, and it should say in printing along the cable that there's ethernet if the Cable has ethernet. HDMI 1.4 cables or better have the ethernet functionality but for future proofing if you don't already have a cable I would buy an HDMI 2.0 or 2.1 cable (with 2.1 being preferable) depending on how long the run is and what your budget is.
Excellent explanation great job
Great explanation, thanks.
Thanks Caleb.
I always have enjoyed your videos
Great, actually got some good info, thanks
very well done and informative
Great video, I appreciate these kind of explanations
Thanks! Lots more of these are coming! Please share with someone who might need it? Appreciated!
All makes a lot of sense!
Love your explanations man! You got a sub from me!
I have a Samsung 55 inch tv with eArc and a Samsung ms650 sound bar that comes with ARC only however i believe the sound bar works as a eArc after my latest update audio quality is so much better than ever. 700w subwoofer and rear speakers wake up more than ever. I listen to music on Tidal Master Audio and ill turn off MQA software encoding and let the soundbar decode everything. It truly sounds amazing! High Mids and lows are super responsive.
This was a great explanation. I have an Xbox series X using eARC to my Atmos compatible soundbar and from soundbar to tv via ARC. Works most of the time, but occasionally I have to disconnect and reconnect the HDMI cable at the Xbox end in order to have it come up on the TV :) was driving me a bit crazy until I watched this. also sometime I get weird turns off Xbox and TV but not soundbar or turns of Xbox and soundbar but not TV.....but hey :P
Nice explanation thanks watching from sg.
Great video, Thanks!!
Great video...thanks
Thank you !
Hi Caleb, That's a clearly described issue with HDMI in certain devices. Let me share my experience how i have connected My LG TV with Sony HTA9 and Apple TV. With eARC (HDMI2)enabled in the TV and Sony HTA9 initially. Once , they are in Sync, I have connected Apple TV to HTA9 . The LG TV has created a sub menu in the HDMI 2 tab with Sony HTA9 to play audio from TV and another tab to enable apple TV to play audio in HTA9.
I have a Sony a80j and u showed me how to get atmos to my sound bar without using a separate device. I can now get dolby vision and atmos. Before I had to choose. Thanks again.
It is very important to find out if a tv has eARC. Almost every tv should have it now but it is a huge deal for watching 4K movies or playing games with Atmos or DTS:X. Thanks for the vid!!
It is not that important.. as hardly any content available with the Tv itself has Uncompressed Multichannel audio..if you play competitively you do it with PCM 2.0.. If you have a dedicated UHD player or Dedicated HighEnd Bluray which will play uncomppressed multichannel audio..
you are certainly plugging those devices directly to the Receiver in first place.
thank you!
Thanks
Thanks now I understand !!
thanks for the video
This actually helped a lot since I have an LG CX I had my 4k player plugged into the TV thinking it would pass the dtsx signal to my soundbar but after watching and finding out the CX doesn't support dts I switched some cables around for it plugging the 4k player into the soundbar
@David Mander crappy? You don't even know what kind of soundbar it is
I've learned about eARC's downfall very early, and the easiest way I found to fix the issue when it stops working is to just unplug the HDMI cable from the television, and plug it right back in, and it'll be back to normal.
Cheers much, great channel
Thanks for the info. I tried earc connected from my Sony A80j and was disappointed with the sound quality. I expected much better. I have it connected to an Onkyo RZ-50. When watching netflix, I compared the apps in my sony thru earc, and using Roku, and there was no contest. The apps sound thru the Roku won hands down.
I just got a new Samsung tu8300. And the e-arc really confused me. So thanks for clearing that up 😁
I wish these TVs would offer an additional audio only out port on TVs, instead of being forced to waste a precious HDMI 2.1 port.
I just use the optical connection for audio, don’t know how good it is but sound great. Keep both 2.1 one for PS5 and Series X on my Sony.
