Netflix Dolby Vision brightness keeps chaning - is there a setting to st

Endless.Riffing — Thu, 21 Nov 2019 07:43:15 GMT

Netflix Dolby Vision has always been fine on my Android TV until Oreo. Now the picture keeps changing brightness / colour temperation whilst watching. For example "The King" seems to be dark then when the camera pans to a slightly lighter angle the screen brightness increases for the whole picture like a "wipe". The colour temp also changes from yellowish to bluish. All ok again when the scene changes. Are there any settings to stop this?

Are you sure it does not depend on the Advanced Contrast Management setting on your edge led tv?

By design Dolby Vision being dynamic can adjust the picture setting scene by scene, but it should not so visible...

I'll try that and see. I really never go into anything in the advanced settings. It wasn't doing this before oreo and now it is. BBC iplayer UHD has no problems.

I just gave up with Netflix 4K in the end and downgraded to normal HD subscription. I got fed up with the fact neither Sony nor Netflix were interested in sorting out the garbage Dolby Vision picture. The HD picture is actually better.

In fairness to Sony, I suspect it's Netflix who are the problem as 4K on Amazon Prime all is stunning... This suggests it's either the Netflix feed or the Netflix app that's dodgy.

I'd encourage everyone to downgrade or cancel their Netflix subscription if only to shake them up.... You can bung it back on anytime within a year and your profiles/faves are all saved. Blindly paying them every month is lazy and encourages their slackness.

Oddly enough this has just started happening with my KD-55XF9005 TV. No setting changes will stop it happening. From what I can gather it seems to be a Netflix app issue with Dolby Vision.

It's just started doing it on my XG9005. Either that or I've never noticed it before.

Fiddling with the settings is futile. I should say that I marginally improved matters by hardwiring my TV to router via ethernet cable. The telly is virtually next to the router and I have good/solid/fast WIFI so I cant believe it was some sort of "signal" issue but, using ethernet the picture improved from shocking to very poor.

Also, Disney+ use Dolby Vision a lot - you could look at that to compare DV pictures?

I read elsewhere that a soft reboot (hold power button down on remote) cures it.

It worked for me, as just rewatched scenes which were changing in brightness and colour temperature and it's fine again.

Looks like a software issue in this case maybe the DV gets its metadata messed up on Netflix.

Edit: well it's pretty rubbish actually as the next thing we watched started doing it again 😞 so rebooting while temporarily fixing it doesn't seem to stick for long.

As an aside Adv. Contrast Enhancer doesn't help even if switched off.

I honestly wish there was a way to disable Dolby Vision on Sony Android TVs.

I honestly thought I was bonkers having experienced exactly this problem. Just add it to the pretty crap Sony experience of a multiple thousand pound TV.

I swear to god, there's something untoward going on with these Sony TVs and throttling I reckon.

Some days there is content available with Atmos, some days not. Disney+ Atmos content is just starting to filter through but, not everything, not everything via the TV's built-in app that has it available elsewhere.

And now this varying experience of DV via Netflix. Not any other app or any other component attached that utilises DV, just Netflix.

Hey CyberWoogy, what's the model number of your TV?

I have this issue as well.

I have the KD-55AF8.

The colour/brightness changing is driving me insane!

Hi andhas, have you tried adjusting the brightness for each source separately? https://helpguide.sony.net/tv/faep1/v1/en/08-02_04.html?hl=brightness

It only happens when I stream Dolby Vision with the apps (Netflix/Disney+) in the TV, so no external sources.

I have tried to disable all the "enhancing" featuers and setting all settings to default.

I have not done a factory reset, I do not want to have to redo all the account settings and so on.

It disappears for some time after I do a reboot.

I guess a factory reset will solve this issue since you've tried all the steps mentioned on the above links already.

@PiscieA factory reset does not solve the issue. It's very unusual behavior and particular to Sony it would seem.

And it isn't limited to the Dolby Vision Bright setting, it also happens on Dolby Vision Dark... why Sony? Why is the brightness not a constant on Dolby Vision?!

This is just the straw that broke the camels back for me, my A90J is going back to the point of purchase to be replaced with a JZ2000.

I've never paid so much for a TV or ever been so unhappy, as well as frustrated, with a purchase of one.
