The built in TV APP's don't test HDMI ports and/or boards related to controlling said ports.

How likely is it that the brand new Apple tV 4k was defective, and the replacement apple tv 4k was defective in the same manor?

If anyone reading would like to chime in about their Dolby Vision experience with this TV and AppleTV 4K, that would be great.
Nobody else is reporting the issue. And the only constant so far is the Apple TV device. I recommend you test another connected device capable of Dolby Vision. If it works fine, then the Apple TV is causing the issue. If it happens again, then you may have a defective display.

What if you go into Network with the Display, select Manual Setup, select the DHCP to Manual then to On (or in Manual, you might have to zero-out all the numbers to zeros - save - then turn DHCP back to On. The Google DNS will come back, but first check to see if this works, then you can go back in and replace the Primary DNS from 8.8.8.8 to 1.1.1.1.

the fact that no one else is reporting the issue (when we know there are likely ten's of thosands of apple tv 4k's hooked to this display) is exactly the reason I think there is something wrong with my TV.

Don't really have "Another Dolby Vision" device in the budget at the moment. No desire for another 4K HDR streamer, and not ready to buy a UHD player yet. Sounds like your suggesting that the expectation for the display to work with an Apple TV 4K is unrealistic.

FWIW, 4K ATV using DV @ 60Hz now works great with my P65-C1 via my AVR and a 50' HDMI cable.

BUT.....I was having similar issues. Tried all the same solutions you listed. Everything worked except 60Hz 4K DV.

In my case it turned out it was the main board of the TV.

If you are not under warranty (or extended warranty) and want to attempt the "nuclear option," inexpensive replacements are readily available online.

The main board of this particular TV integrates all of the AV ports and the SOC (CPU/GPU) onto a single, small board. I paid ~$110 with free shipping for a replacement. The most difficult part was removing, and then re-installing, the several dozen screws on the back of the TV. Once the rear cover is off its a trivial replacement for anybody familiar with modern electronics to swap the board.

If you are not comfortable trying something like this yourself it is a difficultly 1/10 job for a repairman if you supply the board.

I've never tried the 1.1.1.1, only the 8's. Thins were always...weird w/ Google DNS. Name bench put my ISP at the top 90% of the time, so what's the point of not using my own ISP like most auto-configurations do?

For most people, it will be their own ISP's DNS numbers. What they don't know, they don't know. They perform good enough, overall, not to draw attention that there may be a better one to use. They don't know about NameBench or are not tech-savvy to dive into this stuff.

For some of us tinkerers and techies (and Tekies and Trekkers), we can sometimes find better performance with VOIP / InterNet Radio/Podcasts and other streaming, like I did, with a better DNS than the local one. If your local DNS is working for you, stick with it.

The Mobile App from NetFlix Fast is my go-to ISP Speed Checker now. (And on my computer, I go to www.Fast.com to check.)

Before I knew anything about the finer details of DNS choices, I'd be where most others are. Still using my own local ISP DNS, not knowing there may be a better one out there. You have know about it, find it, and use it.

Just for Kix-n-Googles, I'll eventually re-enter my local DNS numbers into my router to see how they're doing. It's been a while since I used/checked them.

Thanks to all of you out there that helped me find out about DNS and how it helped me to find 'the better one'.

Last night I watched a Vudu UHD movie using the Smartcast app and didn't have any buffering at all. This hasn't happened for me in a long time. I'm hoping this lasts and doesn't get screwed up with another firmware update. I had been using the Nvidia Shield but now that device is always buffering when watching Vudu.

I noticed that too with the Shield.... Even just watching HDX.

Vudu has acknowledged that there is a problem and they say they're working on a fix. It's not consistent as I was able to watch "A. I. Artificial Intelligence" the other day all the way through with no buffering but at other times it will start buffering right away.

I tried this last not, changing the Primary DNS to 1.1.1.1 and had no connection. Do I need to change the IP address of the Dispaly?

Anyone have an answer for this? When I go to system information on my P65-E1, either on the display menu itself or via the app, under version it just says 335. I don't see the normal firmware version listed anywhere, have no idea what version I'm on. This is a relatively new replacement, and it's been like this since I received it. Just did another factory reset yesterday to see if it would resolve itself but no dice. When I check for updates it says there are none, and I did get the new Watchfree input.

I wanted you to cycle through the DHCP settings so that with it On, it would auto-fill all the numbers in all over again. You might have to sit on the 'Manual' setting and zero-out all the numbers first - then save, then cycle back to DHCP On. All the boxes will auto-fill with the numbers, including your IP address of the Display. You can test your Apps at this point.

If this solved your problem, you can then go back to the 'Manual' DHCP and try 1.1.1.1 as your Primary DNS at this point.

Just by you saying that 1.1.1.1 is not working for you, tells me there's something messed-up to begin with, hence, the problems you're reporting. After 'resetting' the DHCP in the 'On' mode, how about first using your Router IP as the Primary DNS before using the 1.1.1.1 address in the Vizio.

But, have you first shut-down all devices and done the rebooting of:


  • Modem/Router (wait 3 minutes).
  • Turn on all Network devices.
  • Then turn on Vizio Display last.(Then perhaps additionally, redo Display's Network - perhaps by Factory Reset.)

I've re-seated all the cables, soft power cycled the tv, power cycled all the devices (reset the surge protector), toggled, cec off/arc only/on, full uhd color on/off, and even swapped cables with ones I had laying around.

Anything else I should try before a factory reset?
I'm trying to avoid that since I don't want to have to re-enter in my calibration values for everything.

No matter the brand, it's the High-Speed HDMI Cable Lotto until someone reports a very high and reliable brand is available. I'm not aware of any. Anyone?

The HDMI cable is 'CERTIFIED', yes? 6-Foot? Has it ever been stressed at the cable jacket part going into the connector shell? No bending whatsoever should happen at these points, otherwise internal connections or delicate wires distort or breaking can happen.

Have you flipped/swapped cable ends? (Unless it's a one-direction cable type.)

Swap-out and try other HDMI Cables?

HDMI ports were designed with 6-foot cable lengths in mind. Problems CAN occur with shorter or longer lengths.

Signal testing the HDMI Cable: Ranked Easiest to Play to Maximum Signal 'Stress' Test:


  • 480
  • 720p
  • 1080p
  • 1080p HDR-10
  • 1080p HDR-Dolby Vision
  • 4K
  • 4K HDR-10
  • 4K HDR-Dolby Vision (The first to fail, where other lesser data-rates above can still function, depending on the defective condition of the cable. This resolution along with DV has the most data going through the cable, due to DV having data in every video frame.)

Remote possibility it's related to an issue I have. My aTV 4K (and many other peoples judging by apple support forums) drops its local network connection periodically. It is hardwired, so this is not a wifi issue. For me, this results in:

kicking me back to the main menu screen when streaming music or video from a computer in my house;
screen going black momentarily and quick drop down of the Vizio header display when watching netflix or other streaming service.

If your aTV(s) has this issue as well, it might just be exhibiting slightly different behavior with a DV stream.

edit: I have a P75C1 from April 2016 BTW

Thanks for the input. I did try several cables (even a Monster Cable lol). Basically in the cec settings, no devices are being detected so I contacted vizio and they're sending out a parts kit after some more troubleshooting with them . I'll grab some more "certified ones" to test out later to tonight. I'm 90% convinced it's a main board issue as none of the other cec devices are detected by the tv. The 10% of me still wants to experiment since they pass video and audio to the tv and this occured while I was actually using the soundbar (watching dark knight rises) but the tv just isn't detecting the soundbar as cec-compliant anymore so it wont5 send the audio out to it.

In the meantime I'm just using an optical cable like a pleb for smart tv stuff.

BUT.....I was having similar issues. Tried all the same solutions you listed. Everything worked except 60Hz 4K DV.

In my case it turned out it was the main board of the TV.

If you are not under warranty (or extended warranty) and want to attempt the "nuclear option," inexpensive replacements are readily available online.

The main board of this particular TV integrates all of the AV ports and the SOC (CPU/GPU) onto a single, small board. I paid ~$110 with free shipping for a replacement. The most difficult part was removing, and then re-installing, the several dozen screws on the back of the TV. Once the rear cover is off its a trivial replacement for anybody familiar with modern electronics to swap the board.

If you are not comfortable trying something like this yourself it is a difficultly 1/10 job for a repairman if you supply the board.
Good to know, sounds pretty trivial. Fortunately my set's only 2 months old so it's still under warranty.

kicking me back to the main menu screen when streaming music or video from a computer in my house;
screen going black momentarily and quick drop down of the Vizio header display when watching netflix or other streaming service.

If your aTV(s) has this issue as well, it might just be exhibiting slightly different behavior with a DV stream.

edit: I have a P75C1 from April 2016 BTW

Thanks for the input, however it has this behavior even sitting at the Apple TV menu screen, even the UI has this problem when not streaming anything.

Are the mounting holes on the P75 F1 in the place as the C1?

For some of us tinkerers and techies (and Tekies and Trekkers), we can sometimes find better performance with VOIP / InterNet Radio/Podcasts and other streaming, like I did, with a better DNS than the local one. If your local DNS is working for you, stick with it.

The Mobile App from NetFlix Fast is my go-to ISP Speed Checker now. (And on my computer, I go to www.Fast.com to check.)

Before I knew anything about the finer details of DNS choices, I'd be where most others are. Still using my own local ISP DNS, not knowing there may be a better one out there. You have know about it, find it, and use it.

Just for Kix-n-Googles, I'll eventually re-enter my local DNS numbers into my router to see how they're doing. It's been a while since I used/checked them.

Thanks to all of you out there that helped me find out about DNS and how it helped me to find 'the better one'.

-Well, I've known about other DNS(Google, Open DNS, etc.) and Namebench for several years now.
-I'm tech savvy as far as I set up my own wireless networks, and how to configure the settings in my Evenroute and Apple routers.
-Fast.com was the most horribly inaccurate of all speed tests I've used for my gig connection so far.
-What makes you think that the 1.1.1.1 is a better DNS than that of a major ISP's?

BeeCawz, I'm an Eggzpert!

Better for me, that is. Maybe not everyone.

And 1.1.1.1 is a 'Major' DNS:

The owner of the IP address 1.1.1.1
(1dot1dot1dot1.cloudflare-dns.com - Google Inc.)
is located at (Australia - ).



Really, my discovery was with brief drops and lost connections with Tune-In Radio and my Magic-Jerk calls dropping, and a performance change when using another DNS. That convinced me DNS DOES INDEED have a quality of speed and performance, not just Name Look-ups. I don't know the tech details on why, I just know my own, local results.

Once I started playing around with different DNS address and all of a sudden my VOIP calls and Tune-In Radio held up much longer or don't drop or hiccup like they did with my local DNS, it was 'game' on.

I got my fastest speed with 'Fast' when I changed it to nearby DNS (not my ISP), from a NameBench result. It soon, had gone south for a number of days in a row, and I had 'Fast' speeds on my Vizio Tablet around the upper teens and into the 20's. Too low! Not normal for me.

Once I changed it to 1.1.1.1 some weeks back, BOOM! The mobile App 'Fast' now reports around 40+ of my ISP speed of 60Mbps. 8.8.8.8 wasn't the best in performance, for me, on average, and I think it had 'dips/drops' with my VOIP/Radio streaming. (I'll use it again at some point and check all my DNS entries over again and rank them based on my local experience with them.)

So, I use NameBench and my VOIP/Radio streaming testing to pick the best DNS for my location. 'Your Vary may Mileage'.
