Thanks for the update.
I have actually turned my contrast enhancer off and I still see the issue present...
The subtitle ligtht bloom issue, not the light fluctuation issue I reported?
I tried all the changes in pictures modes I could do but the problem persists. The 2 unique things that slightly improve the light fluctuations with subtitles are:
-Change the subtitles color to yellow or dark grey
-turn local dimming to low
Tomorrow I will do a remote assistance with Samsung. I'll keep you updated
On the issues I've been talking about where I've been seeing light fluctuations & flickering on some scenes, I've found that it's made a lot better by setting Local Dimming to Low, and Contrast Enhancer to Off. This is for non-HDR content.. if I try to watch HDR with those settings it's waaaay to dark. Nothing back from Samsung Support.
I own a Q7FN and it is suffering from the same issues. I was considering upgrading to the Q9 because of that but now I see it is the same :(
I also tried the above picture settings, but as you said, dark scenes become extremely dark in these settings.
I don't understand how this is not top priority for Samsung tech to resolve.
It's not top priority because reviewers of those TVs never mention such things and people keep buying it.
But I believe Samsung intentionally implemented it that way in order to "cover" other issues and that's why it's not easy/possible at all to be fixed. I wouldn't hold my breath on a fix. Just make sure to let your friends/forums know about your experience so that Samsung start taking people's feedback seriously.
Started to look at whether other manufacturers, like LG, have had similar issues & came across this article; https://www.forbes.com/sites/johnarcher/2018/10/15/lg-oled-tv-owners-driven-to-distraction-by-latest...
So it's not just Samsung who are having issues balancing the light output. I'd like to hear from Samsung on the issues we've raised here. Feels like they're not bothered.
Some updates here
I contacted with Samsung and they accesed my TV remotely. They didnt see any problem. Although I have to say that when they accesed, my TV showed a bright icon at top right (to make sure they are remotely there) so the local dimming stayed "bright" and did not make those abrupt changes.
They told me that they could ask the technical service to come to inspect the television but "I would have to pay for the transport expenses of the technical service if the technical service after the inspection said that my television worked correctly" with what I did not agree......
I contacted aswell with HDTVTest (Vincent Teoh) and i showed him the video with my problem. He said its a normal behaviour because the local dimming and the bright HDR content (these problems are reviewed in his videos with the q8dn/q8fn (FALD), q9fn, x930e, x900f etc...)
So I'm sorry guys I didn't get any solutions
To improve the problem with HDR content try to:
- Change local dimming to low (if the image is too dark after this change try to change contrast enhancer to low or high)
- I have tried dimming low + contrast high and the image is similar to dimming high + contrast off and I have less problems with subtitles...
- Change the subtitles color to yellow/grey
- Change the size of the subtitles to small/tiny
- If the app lets you put a black box around the subtitles
