Hi,
This may sound like an odd question.
I have the XMC-1 which of course does not support 4K (YET!). I have it connected to my 4K LG tv with HDMI and optical. The reason for optical is that the ARC does not seem to work correctly, as I cannot get any sound out of the HDMI when using the tv's apps. So when I watch Netflix, I use the optical settings to get the sound.
My question is:
When I watch 4K on Netflix, when pressing the info button on the XMC-1, it writes "1920x1080". Is this because it cannot detect that it's 4K or is it because it's NOT 4K?
If it's not 4K, what is the reason for that? Is it because the tv is also connected to the XMC-1 via HDMI?
Hope you guys understand and can help.

If you have an early XMC-1 with the original HDMI board it cannot pass protected 4K content. Can you connect your Netflix source directly to your TV?

Hi Geebo,
Sure I have not explained good enough. The Netflix content is directly from the tv (smart tv), so it's only the sound (hopefully) that's run to the receiver. But that's where I'm unsure.

That's the resolution of the XMC-1 GUI. If your Netflix is native to the LG 4KTV and you have Netflix's 4k subscription you will see 4K on the LG TV. When you select the fiber optics or TOSHLINK input to get sound from the TV, the XMC-1 will display 1080p on its OLED screen, but that is just its GUI resolution. Emotiva did a horrible job implementing ARC --hopefully, it's fixed on their new board. Hi Geebo, Sure I have not explained good enough.

Does the tv say it's in 4k? Usually there's a display mode that will let you know. Also netflix will have a 4k word option there.

It's because you can never select JUST the optical input. You're selecting an HDMI input that has been programmed to use audio from the optical input. So, whatever HDMI input is selected is sending a 1920x1080 signal, even though that's not what you're viewing on your TV. Or, if there is no HDMI source connected to that particular HDMI input, the XMC-1 is still expecting a 1920x1080 signal. |

if you can see tags like hdr or ultra 4k with the tv shows or movies that you will have it also on your screen.
I have an nvidia shield with netflix app connected to my xmc-1 and can not see those tags, but when I search the same tv show or moovie directly from the netflix app on my tv (also connected to my xmc-1 thru hdmi) I do see them

You would want to hit the info button on your TV to see what video resolution it is displaying, not on the XMC-1.

I have that exact setup on my LG OLED - Send optical out from the TV to the XMC-1 (I call the input "LG TV").
When I'm watching the smart TV video, the XMC-1 is only processing the optical audio signal. Everything else is handled by the TV.

To get ARC to work I had to;
turn on CEC (yes I know, what has CEC got to do with ARC, but that's how it was).
use the HDMI port labeled ARC on the TV.
use a HDMI cable that specifically said that it was ARC enabled (mine also has ethernet support, they seem to be common in HDMI cables).
Cheers

Cheers Gary Yes ( I had to do the same thing) and a side effect was that when I wanted to watch TV with sound from my MC-700, my BR player would power up and take over the HDMI input. The further solution was to disable CEC on my Blue Ray Player..... Now it works as desired. |

Has anyone been able to get ARC working with an XMC and a LG OLED tv?

Has anyone been able to get ARC working with an XMC and a LG OLED tv? Yes, my daughter has one and my list above refers to what I had to do for ARC to work. It was slightly different to my Samsung, but the same principles applied. I thought the CEC thing was just Samsung, but it seems that others are just as illogical. What the hell ARC has to do with CEC I have no idea  Cheers Gary |

If you're watching 4k Netflix directly on the TV, the XMC-1 has no idea what resolution it is (because the video is not going through the XMC-1). The XMC-1 is showing you the resolution of ITS video input.. HDMI inputs provide both a video and an audio source to the XMC-1. When you select an input on the XMC-1 that contains ONLY audio (like Optical).... - the audio source switches to the one you selected - the video source remains set to whatever it was before (assuming the previous source has a video signal) - (this is considered to be a feature... for example, it would allow you to leave a nature video playing while listening to a CD, or watch a ball game while listening to the calls on the radio) So, when you select the Optical input, the XMC-1 continues to display video from whatever source was selected before you changed inputs. So that 1920x1080 is the video resolution of that source.... (And, I believe, if there is no video source, or it's turned off, the XMC-1 will default to 1080p.)

Thank you guys!!
This was really informative. Lots of help.
Now, like the rest of you, I'm eagerly waiting for the new HDMI board to be released. Hopefully this will help with the ARC problems.

Okay, I feel dumb. I was snooping around in the input settings and finally found ARC as an audio input on input 8. I was trying to get ARC to work with input two and HDMI 1 as the audio input. Seems obvious now, switching to HDMI 8 and selecting ARC as the audio input did the trick. DOH!

ARC and the way it works with CEC is a pain, but it's the game we have to play with a Samsung Smart TV.

If you disable CEC on the XMC-1 the TV should no longer be able to shut it off. You'll find that setting under Setup | HDMI-CEC on the menu. If you JUST uncheck "Power Off" it should prevent other devices from telling the XMC-1 to turn off. If you uncheck the Enable box you will disable all CEC functionality (which includes ARC) I have a sony 4k tv and it also doesnt now allow me to use arc and i know use optical for netflix from the Tv..however my ARc DID WoRK for awhile and then poof did not ..also when i connect the xmc1 to the tv via hdmi since im running my 4k blue ray player into the xmc shutting off my tv also shuts off the xmc1 which is not good if i want to listen to music after watching tv..had to take out the hdmi cord didnt see any settings on the tv and i dont have it connected any other way |

Just for the record..... ARC is an AUDIO ONLY input source. The actual ARC audio signal enters the XMC-1 through the HDMI output connection to the TV. (The ARC audio signal is sent "backwards" through the HDMI cable connecting the output of the XMC-1 to the input on the TV.) ARC relies on CEC to work.... and will not work if CEC is totally disabled. Also, TVs generally only support ARC on ONE of their inputs.... so you have to use the right one. Okay, I feel dumb. I was snooping around in the input settings and finally found ARC as an audio input on input 8. I was trying to get ARC to work with input two and HDMI 1 as the audio input. Seems obvious now, switching to HDMI 8 and selecting ARC as the audio input did the trick. DOH! |
