Hi! I have recently purchased this magnificent grand OLED TV and have been enjoying for the past 2 weeks. When watching Netflix (mainly) I noticed from time to time the colour changes to what looks like Sepia-ish or tri-tone colours. I had no idea what to do at first and definitely certain it is not a Netflix setting issue.
I found that all I had to do was to just to exit the "Action Menu > Picture" menu by clicking "Back". A few seconds later, it will switch back to normal colours. I have not done any changes to anything doing this. Really strange!
In addition to other people's comments I can add that mine does it when flicking between CGI imagary and none CGI. But it happened for the last 20 minutes of Avengers Infinity War. And has continued for Endgame. Watching on Disney+
So I may actually have a solution to this even though it only happened yesterday. Poor internet! I double checked and for 4k/IMAX Enhanced stuff a speed of 50+Meg is recommended. Are all of you using WiFi? Or hardwired? What's your broadband speed?
This is a bug in the TV software that Sony can't be bothered to fix. Has been happening to me for about a year now. The only thing that fixes it is a hard reset. Some of the ideas posted here like clearing caches and resetting to factory settings are obviously nonsense and infuriating. Sony need to fix it and nonsense suggestions are just a distraction from that fact. There is a bug in the TV (or Android OS) handling of dolby vision colour profiles (and the way they interact with apps) that Sony just need to own up to and fix.
TV is a LG C1 65". Device is a CCwGTV 4k, updated. Connected to an HDMI port that says eARC (seems to be different). Display settings are exactly the same between inputs. TV is updated, device is updated. I'm watching the same episode over Netflix. CCwGTV is set to use Dolby Vision, 4k 60hz. When I play a Dolby Vision media, my TV shows a little pop-up saying Dolby vision or something. This happens on both native and CCwGTV.
I much prefer using Google TV than webOS, even though webOS gives me a cursor with the remote. However a dead color/brightness is an absolute dealbreaker, as it completely invalidates my investment in an OLED TV.
I tried my best to make a good recording. As stable as I could, dark room, tapped to auto adjust focus and brightness on a still frame on the native Netflix app, then locked it. Played a bit of the episode, then paused the recording, switched to the CCwGTV, opened the episode over there, jumped to about the same spot as I recorded previously, then restarted recording.
I've googled a bit (5 min or so) and it seems to be a recurring issue, and that Apple TV devices aren't affected, so it's definitely a Google device issue. I'd love to provide any info needed to solve this, for me and everyone else suffering from this issue.
Quick question: have you checked if the same issue persists when watching a video content from a different app? Please go to the Chromecast with Google TV (4K) setting > Dynamic range format preference > Color format > Choose your preferred color format. Check if it will improve the image or video quality when watching a video from Netflix.
Just checking in to make sure that you've seen my response. Please let me know if you still need help or if you have other questions or concerns as I will be locking this in 24 hours. Feel free to start a new thread and we'll be happy to help.
I'm having an issue with Netflix on my new Stream puck. Whenever I watch something that streams in Dolby Vision the colours go super bright and everything looks really red/orange. It only seems to happen on Dolby Vision, standard 4K seems fine. The bright colours then remain when I go back to the Sky menu system and I can reset them to how they were before by watching something that's not in Dolby Vision (e.g. a TV channel stream).
@PDiddle how your TV renders the Dolby Vision signal is down to the TVs setting and its capability the Stream only passes through the signal it receives Netflix Dolby Vision renders well on most TVs.
Looking at your TV's manual it recommends setting the HDR Plus setting in the Advanced Picture Settings to on - you look to be only able to do that while the set is receiving a HDR signal. Most TVs including yours will save a different set of picture options for each input for SDR and HDR content. Normally using a preset like ISF mode is the most accurate. Avoid modes like HDR vivid unless you feel your retina's need a suntan.
Thanks for the reply @Chrisee . This does seem to have (mostly) done the trick. The biggest difference was actually changing the picture style from one of the HDR settings (e.g. HDR Personal) and changing to Dolby Vision Bright/Dark. All the Netflix content is picked up as Dolby Vision so HDR settings weren't available. I had to stream from Amazon to find something detected as HDR and open up the HDR settings, but I think BBC iPlayer UHD content comes through as HDR too. The TV actually handles HDR itself really badly, but I'll need a better TV to resolve that one.
Once I'd changed to Dolby Vision Dark/Bright I still had to reduce colour down by about 50%. It looks reasonable now though, so hopefully those settings will stick. All quite strange seeing as Dolby Vision streaming from the TV's native Netflix app was totally fine.
Most TV's should detect when a Dolby Vision signal is being received and switch automatically to an appropriate Dolby Vision picture mode (normally Dark or Bright) so you shouldn't need to use any other HDR setting.
@PDiddle to clarify High Dynamic Range content is delivered through different systems or codecs. Your TV supports standard HDR10 - a basic version widly used by apps like Prime, HLG - a specialised system used by broadcasters like BBC and Sky and Dolby Vision which is considered the best as it is dynamic. When TVs detect a programme in HDR they switch to a different mode - most noticeably they get a lot brighter - and then decode the incoming signal using the appropriste codec. You can set the TVs HDR settings only while the TV is in HDR mode shouldnt matter which codec.
People's tastes in picture quailty varies grestly and TV makers chuck in a lot of different controls to allow personalisation. Real nerds pay professionals to calibrate their TVs using complex cameras and equipment. However for most of us a preset like ISF day or night is the best place to start as the ISF setup is used by the industry while preparing the material. Philips have a good rep for picture quaility. Movie mode etc are similar doesnt matter which you use as long as you like the results.
Thanks @SlenderRobert . When I was streaming Dolby Vision from Netflix the TV was definitely set to an HDR picture mode. Perhaps there's a problem with the TV not automatically detecting it, but now I've set it to Dolby Vision myself it seems much better.
On the UHD issues, I thought it might be something to do with tone mapping . it's an old TV and was pretty cheap when new, so I'm presuming it's not the best. I say this as I can't get the image to look any better, no matter how much I crank the settings up.
Maybe check Philips for software updates in case it needs a Dolby Vision profile update. Does the Netflix app on the TV itself show the Dolby Vision logo beside the programme description or does it just say HDR? The Netflix app usually detects what formats are available dependent on the capability of the TV so should show Dolby Vision and select the correct picture mode.
@SlenderRobert So when playing Dolby Vision on Netflix TV shows a message of 'Dolby Vision', when playing HDR on Amazon and UHD on BBC I get the message of 'HDR signal'. So it seems to detect it okay. I've tweaked the HDR settings to oblivion, but it still ends up looking washed out. This is why I think maybe the peak brightness isn't up to much, but I can't actually find any reference to what the peak brightness on this TV is. I can crank up the brightness to make it reasonably watchable, but a result of that is that the blacks end up looking quite grey.
