Funny, when playing 4K movies in prime, when set to auto, it plays at 2160p and HDR. It seems, the Netflix app wont switch to the proper resolution when playing 4K movies within the firestick.


Is anyone else having this issue. If so, did you find a fix, or is the workaround the fix.


Thanks!
It has never switched resolutions. That is normal. Set it to 2160P output.
And if you turn on frame rate sync, it will switch framerates with Amazon video , but not with Netflix.

Mine does the same. I assume this occurs because the B6 does not support DoVi @ 60 Hz, but have never confirmed.

Correction - We have ours set to Auto ((up to 4k Ultra HD). But I don't think it is a issue with the Stick. We just finished the latest season of Jessica Jones and every episode played just fine in DV on our LG OLED65B7A. Honestly we have never had any issue with shows playing in either HDR or DV.

Our settings under Display on the Stick are:
Video Resolution - Auto (up to 4k Ultra HD)
Match Original Frame Rate - On
Color Depth - Up to 12 bits
Color Format - YCbCr
Dynamic Range Settings - Adaptive

Hope that helps.

I have an odd video playback quality issue when I'm watching things on my Firestick whether it's netflix/prime streaming, or playing files off my network through plex. The best way I can describe it, is that the image (usually background) is very "wavy" instead of just a regular clear picture. If I play the same movie file for instance just straight off my TV's media player, the picture looks normal. I wish I knew the exact terminology for the visual distortion I'm talking about, hopefully my description will make sense though. Any ideas?

I discovered this same issue with the Netflix app the other day. Forcing the FireTV stick to 2160p results in HDR10, and no DV. Setting the FireTV back to Auto gets you DV, but only 1080p playback in Netflix. In fact, the Netflix UI only indicates "HD" on titles that are UHD when played from other devices (like the TV's built-in apps). My guess is that the FireTV Netflix app simply doesn't support UHD, and the FireTV just upscales it (without DV) when forced to the 2160p setting. Amazon Prime Video 4K titles play just fine in UHD, so it's not the FireTV stick. It's the Netflix app.

My settings are the same, except, I have color set to auto. It will play DV; however, it plays it at 1080p, when set to auto, not 2160p.

Yeah, I think it's the netflix app within the firestick because, when I use the netflix app through the LG TV, it plays DV at 2160p strange. I used the LG TV Plus remote app to verify this, since there is no info button on the regular LG remote.

With settings as I posted it plays DV at 2160p for me (just checked S3:E13 of Jessica Jones). IIRC, you indicated that you were using a B6? Maybe that’s the difference since I’m using a B7?

I’m not seeing this behavior at all with the NetFlix app running on any of my FireTV Stick 4k’s (I have 3 of them). They play DV at 2160p just fine. I posted my settings back a few posts.

Edit - in going back over some of these posts this looks like it may be an issue with the B6 not the NetFlix app on the FireTV Stick 4k. The app itself plays DV at 2160p just fine.

I wasn't able to get any responses when making a seperate thread, so I'll try here again. During 4k playback of any app (netflix, prime, plex) on my firestick apparently I get a ton of "banding". In the attached picture below you can see when looking at the sky what I mean hopefully. I've tried my internal apps on the TV, and my 4k UHD disc player, and neither have this issue so it's not a network speed issue. Can this be an issue with the fire stick hardware? Any ideas on how I might be able to troubleshoot this?

It's more than likely a settings issue with either the stick or your TV. First check the settings on your TV for the specific HDMI input you are using for the stick to ensure that deep color (or whatever your TV calls it) is turned on. Remember that on most TV's the settings for the HDMI inputs are independent and need to be set for each HDMI input. Second check your video settings on your stick. They should be like this -

Video Resolution - Auto (up to 4k Ultra HD)
Match Original Frame Rate - On
Color Depth - Up to 12 bits
Color Format - YCbCr (note - auto should work here as well)
Dynamic Range Settings - Adaptive

Yes, I have the LG B6.

When I use the Netflix app via the LG TV, it plays DV at 2160p; however, when using the Netflix app via the FireStick, it plays DV at 1080p. Within the FireStick, I have to set the resolution to 2160p in order to get 2160p in Netflix, and then, it displays the picture in HDR, not DV.

This leads me to think it’s something with the FireStick when set to auto, it doesn’t switch to the 2160p resolution for Netflix; however, it does switch to the 2160p resolution for Amazon Prime 4K and HDR movies.

It’s just weird.

This is not an issue with or a limitation of the FireTV Stick 4k. This is apparently an issue with the LG 6 series HDMI inputs (which is why it doesn't occur when you use the internal TV app, see post 1112 several posts back). I can't personally confirm since I have never owned a LG 6 series and have never researched them but it is consistent with what other owners of the LG 6 series have reported here.

The B6 will not accept Dolby Vision at 4K60 from an external source (Fire TV). The B7 will. This is why you are seeing a difference.

The Fire TV Netflix app does not automatically adjust frame rate like Prime does (even if you enable frame rate switching in the Fire TV setup). Netflix is always locked to 60 Hz. Thus, when the Fire TV queries the B6 to find out if it's OK to send Dolby Vision at 4K60 from Netflix, the B6 says "no," so the Fire TV sends HDR-10 at 4K60 instead.

If you set the Fire TV to automatically select resolution, it prioritizes dynamic range over resolution. (Again, this applies only to B6.) For apps other than Prime, the output will be 2K60 (1080p) and the Fire TV will switch to Dolby Vision or HDR-10 as needed (assuming range switching is enabled in Fire TV setup). For Prime, the frame rate, resolution, and range switching are all supported, so the output switches to 4K24 Dolby Vision or HDR-10 as needed.

If you lock the Fire TV output to 4K60 (2160p) in setup, the frame rate will also lock to 60 Hz for every app and every format - including Prime and Dolby Vision. Since the B6 cannot accept Dolby Vision at 4K60, Dolby Vision output from the Fire TV for every app will be disabled and HDR-10 will be sent instead (if available).

It's quirky the way Amazon decided to set this up in the Fire TV, further complicated by the B6's atypical limitation of only being able to accept Dolby Vision up to 4K30 (this is due to the B6 being a very early generation Dolby Vision display). It's complicated, and I don't feel like I've explained it very well; I had to type in a hurry on my way out the door.

Hope it helps!

That is a good explanation and hopefully clears up the issue for those using the LG 6 series with the FireTV Stick 4k.

Yup those are my settings, not sure what the issue could be. I even did a factory reset on the firestick to see if that helps anything. I've attached an image of just the background sitting in the menu, I'm assuming it's not supposed to look like that and just be a smooth colored background?

Menus are not a good thing to look at. I'm curious as to where that menu is though. The background on my settings menu is black not blue. Is this a FireTV Stick 4k (not a FireTV Stick gen 3 aka pendant/dongle or FireTV gen 2 box)? That background looks much closer to my gen 2 box connected to a 1080p tv although even then it's much blacker than that pic. Anyway, like I said, menus are not a good place to judge as they are normally rendered poorly. Check using some good known quality content.

It is a fire tv stick 4k, got it about 3 months ago now but didn't use it a whole lot for the first while. Going to play around with TV picture settings to see what things can be done, and I'm hopefully getting the TV professionally calibrated next month.

When I use the Netflix app via the LG TV, it plays DV at 2160p; however, when using the Netflix app via the FireStick, it plays DV at 1080p. Within the FireStick, I have to set the resolution to 2160p in order to get 2160p in Netflix, and then, it displays the picture in HDR, not DV.

This leads me to think it’️s something with the FireStick when set to auto, it doesn’️t switch to the 2160p resolution for Netflix; however, it does switch to the 2160p resolution for Amazon Prime 4K and HDR movies.

It’️s just weird.
The B6 will not accept Dolby Vision at 4K60 from an external source (Fire TV). The B7 will. This is why you are seeing a difference.

The Fire TV Netflix app does not automatically adjust frame rate like Prime does (even if you enable frame rate switching in the Fire TV setup). Netflix is always locked to 60 Hz. Thus, when the Fire TV queries the B6 to find out if it's OK to send Dolby Vision at 4K60 from Netflix, the B6 says "no," so the Fire TV sends HDR-10 at 4K60 instead.

If you set the Fire TV to automatically select resolution, it prioritizes dynamic range over resolution. (Again, this applies only to B6.) For apps other than Prime, the output will be 2K60 (1080p) and the Fire TV will switch to Dolby Vision or HDR-10 as needed (assuming range switching is enabled in Fire TV setup). For Prime, the frame rate, resolution, and range switching are all supported, so the output switches to 4K24 Dolby Vision or HDR-10 as needed.

If you lock the Fire TV output to 4K60 (2160p) in setup, the frame rate will also lock to 60 Hz for every app and every format - including Prime and Dolby Vision. Since the B6 cannot accept Dolby Vision at 4K60, Dolby Vision output from the Fire TV for every app will be disabled and HDR-10 will be sent instead (if available).

It's quirky the way Amazon decided to set this up in the Fire TV, further complicated by the B6's atypical limitation of only being able to accept Dolby Vision up to 4K30 (this is due to the B6 being a very early generation Dolby Vision display). It's complicated, and I don't feel like I've explained it very well; I had to type in a hurry on my way out the door. [IMG class=inlineimg]/forum/images/smilies/redface.gif[/IMG]

Hope it helps! [IMG class=inlineimg]/forum/images/smilies/wink.gif[/IMG]


Thanks, yes it does. I guess I need a new OLED, lol.

It's likely a pain; typically, framerate is set to native of panel. But you might have some results with fixed frame rate, like 24 or 30 for Dolby Vision for Netflix. Unless Netflix did the Fire devices like it recently did the Roku with framerate.

I do wish the app developers would be more mindful of auto framerate as a feature users want. After all, the feature can be disabled if users don't want it. But Netflix recently limited Roku to 60 Hz refresh rate because users were complaining of framerate switching for auto play previews.

Hopefully the Apple TV 4K won't be next. But somehow that device isn't doing framerate switching so much that I've seen except for content. Maybe it would for a TV app with commercials that framerate matches? I dunno. What I've seen with Roku, it doesn't handle this so well, on my TV, it changes framerate prematurely, really hacks commercials and never got Hulu right with framerate switching. Maybe that's why Amazon limits this to what it can control?

It's my understanding that the native frame rate lockout was a Roku decision, not Netflix.

Could be. I didn't mean to take a side. Disappointing though.

Very.

Hi there!

Thanks for the notes here. I followed up with our team, and it looks like this is the current intended behavior as of OS 9.1. The 'Auto-adjust display refresh rate' feature no longer applies to the Netflix channel at this time.

I apologize for any confusion here. I'll continue to provide any further updates here if there is any additional news to share.

Thanks,
Tanner

Here in the UK I'm having the same problem with the UHD HLG Wimbledon tennis on the BBC iPlayer. On Auto I get HDR/HLG but only at 1080p.

Need to manually set it to 2160p 50Hz.

Yes, you can side load the VUDU app. You will have to use another platform to buy or rent titles but once you do they will appear in the app on the FireTV device. And it will support HDR/DV with ATMOS.
