Problem solved, at least for me: i've returned the 55Q9FN and got a Panasonic TX-55FZW804 OLED. Good choice so far!
I liked the design, the remote control, free sync for gaming over Xbox and cable management of the Samsung Q9 and miss this features a little bit. But the picture quality is improved dramatically! And thats what it is about, isnt it? No subtitle issue of course, absolute black and a lot more control / settings for the tech nerds. No TV+ and commercials in the menu, yeah! Sound of the TV is much better too.
I hope Samsung will fix the problem some day and the TVs will work as intended.
A week ago I bought the QLED 65 8curve and have the same problem with local dimming. It is happening at Netflix with a dark bar at the bottom. The color of the subtitles goes up and down from white to blue-gray. Is annoying for a TV in this price range and its a real problem that playing world wide. Hope Samsung comes quickly with a update/solution for all the loyal buyers of these QLED TV´s.
I have bought the 75” q6 about 3 weeknd ago, and the second day i noticed this problem right away.
I have talked with the samsung support and sent them the link to this thread and also a couple of youtube clips and other forums about this issue. And i sent them a videoclip of my tv when this problem shows up.
So samsung is saying there is nothing wrong with my TV and basiclly i just have to live with it. This is crazy, i have tried every setting to make this issue go away but it dosent. I have set Netflix subtiles to the smallest and choose the yellow color for it, and that does help.
But i see this issue even without there is subtiles, when there is a dark scene and some light appears in the scene.
Hi guys. Have the same problem as i have said before.
Do do you experience the same issue on other sources? Like, other streaming platforms or Xbox or so?
On HBO for example it is not that big problem, is it because of their subtitles or is it because it’s not that good 4K/hdr quality?
So unfortunate to be hearing about these dimming issues on these televisions; my NU8000, which is the step just before getting into the QLEDs, exhibits HORRENDOUS flashlighting/blooming/dimming when watching in a dark room, and it's almost to the point of being intolerable...however, I learned only AFTER I purchased this set that edge-lit designs is what makes these issues worse, and I'll tell you this -- I'll NEVER buy an edge-lit LED again.
But the QLEDs don't use edge-lit designs, do they? The fact that these units are exhibiting terrible dimming and blooming without utilizing an edge-lit protocol is a bit offputting...
I have the same problem with my recently purchased Q65fn 55 inch, it's really annoying when watching movies thru a USB thumb drive or Netflix. SAMSUNG you should know how expensive these TVs are..., start looking into a solution...
Same problem with my brand new NU8500. And the other issue that i have is with the color of the subtitles, watching Man of Steel, BvS and Braveheart (the three in 4K) in dark scenes are grey, in scenes with ambient light like the moon or an explosion are white. Unveliable, Samsung.
