I went through like 4 different HDMI cables, very frustrating process but this Belkin cable works flawlessly, they are more expensive but 100% worth it, no static in image or problems what so ever.

Also worth noting that if you are using a soundbar with 4k passthrough, an Apple TV is essentially your only option to get DV content. Xbox one x has this very annoying bug that doesn’t pass through DV when using a soundbar.

Sure, here my details:

1. LG OLED55B7V
   
   
2. Firmware 4.70.85
   
   
3. HDMI Port 1
   
   
4. HDR and Deep color are enabled on HDMI Port 1
   
   
5. I tried using both the official supplied Xbox One X HDMI cable and a new HDMI 2.1 Certified cable . The issue happens on both
   
   
6. No AVR or soundbars or receivers are being used. Only direct connection from console to TV
   
   
7. (Bonus) This is my detailed setup and calibration, if can help.
   
   
   I also noticed that the the issue happens a bit less with the new HDMI 2.1 cable, but still happens randomly after resuming the console from standby and launching an HDR content...

Here’s the link from amazon, but I bought it from the Apple Store

I use this one

1. HDMI Ultra HD Deep Colour is enabled on the 4 HDMI inputs on the set manually from when I purchased it and I have double checked that is still the case. It is.
   
2. In Windows 10 "HDR + WCG" is in the toggled "on" position.
   
3. I was using a bog standard HDMI cable, but I had a spare one of these from when I ordered two for my AppleTV:
   
   https://www.amazon.es/gp/product/B075N83B9X/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
   
   No change in behaviour with the Belkin cable over the bog standard one.
   
   
4. I have not tried MadVR + MPC yet, will see if I can energise myself to try that over the weekend.
   
   Thanks for your input.

I purchased a Belkin Ultra HD High Speed HDMI Cable from Amazon yesterday. It's the cable that Apple recommends for their Apple TV 4k so its guaranteed to be able to play Dolby Vision content. It should arrive by tomorrow. I am going to use that cable as the one that connects the receiver to the tv. So after I swap out the Amazon Basics HDMI cable for the Belkin HDMI Cable this should isolate if its truly an HDMI cable issue. I will update you tomorrow with the results.

Here is the link for the Belkin Ultra HD High Speed HDMI Cable if you want to check it out:

I appreciate the cable change recommendation but I have gone through 3 types of cables including the Vizio OEM cable, AmazonBasics High-Speed HDMI Cable (18Gbps), and finally the Belkin Ultra HD High Speed HDMI Cable (48Gbps). If a 48Gbps cable (at 3x the price) that supports the latest standard HDMI 2.1 (4K/120Hz and 8K/60Hz) can't do 4K/60Hz then it can't be a cable/bandwidth issue.

these are pretty good as well

got it re : refresh rate.. I will move the refresh rate to 30 hz.

AVR : Denoon X4500H : http://manuals.denon.com/AVRX4500H/EU/EN/DRDZSYzvebvotm.php

HDMI Cable (both PC--> AVR and AVR --> TV): Belkin 4K : https://www.amazon.com/gp/product/B075N83B9X/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 so HDMI does support it

​

Looking at the denon, I am realizing that i have set it to standard .. so I will set it to Enhanced. I am assuming that i should keep the HDR setting in Windows 10 switched off.

Side note: I dream of the day when all this is plug and play - SOME DAY

Do you have any other 4K HDR sources you can test with? It could be the cable. 4K HDR signals at 60 Hz require a lot of bandwidth – right at the upper limit of what can be sent over a high speed HDMI cable. The symptoms you’re describing may indicate that the cable is too long or not quite up to spec. You don’t have to spend a ton of money on solid gold cables; an Amazon Basics high speed HDMI cable should be perfect. If you really want to future proof, you can grab a Belkin ultra high speed cable.

Thank you very much for the thorough answer.

So, Goobay, PureLink or Belkin, right? What I found odd is that, looking at the Goobay cable's specs, it says that all versions support YCbCr 4:4:2 and 4:4:4, but only the premium one supports 4:2:0.

I believe my TV has a 8 bit panel, but supports 10 bit HDR, something like that. Anyway, it's an entry model, so I'll stick to 8 bit.

I think you're onto something in regards to the cables...

I went ahead and purchased this one.

It'll be here Thursday, I look forward to testing it out.

It's entirely possible you're right. I've been out of the Home Theater game since 2015 or so and perfectly happy with my 1080p/7.1 setup. I didnt ever think cables mattered and always just ran monoprice cables. And now I was getting all these issues and I found that cable when I was searching/complaining online about my TV not passing the dolby vision test. This is that cable:

They sell this cable at the Apple Store and Apple's website and its supposed to be the 'de facto' cable for people having Dolby Vision issues. its supposedly rated at 48gbps. Its possible that the cable is a lemon, its too late to return them, but I suppose I could swap them out to see if that changes anything.

I've asked about my problem on this and other forums, and everyone is chiming in with a recommendation for a cable that will 'definitely work', so idk, maybe I have to keep trying till it gets resolved. I sort of wish there was a sticky for 'tried and true cables' that work for different brands.

This one’s not cheap, but it works for the couple of 4K devices I’ve thrown at it, to the top standards. I’ve had others that didn’t work and I’d rather pay for it to work. Done with experimenting.
