Of course. But subtitles should work well with local dimming on too.

That's the point. Disabling local dimming is a fix (it's possibile, but not easy), not a solution.

The real soloution is a local dimming algorithm which doesn't process on-screen overlays, such as subtitles, with the main movie. It should be simple, but apparently is a common mistake in other vendors too. And it's almost unbelievable.

Someone give me their settings to try this out, I’m still not seeing this issue on my screen. 

 

Also the local dimming is AI powered from what I’ve read, there’s a substantial FW upgrade coming that includes airplay coming soon, maybe Samsung will improve it with that update?

Harsh man, I don't know all the ins and outs. All I know is that I've never seen it improve a picture in LED tv

If it’s an edge lit led tv then yes local dimming can cause issues from input lag to a un uniform display so your partially right.

 

On a FALD (Full Array Local Dimming) display though they literally have hundreds of lighting “zones” that helps give you those deep blacks on LED tech and can give a more uniform looking display, along with prevent clouding from a display better (that was a big issue on KS9000 tv’s) although this subject is moaning about clouding / overly harsh backlight issues behind subs.

I have a FALD model and the situation with the Subs is horrendous. Hence yes, local dimming is potentially a good feature, but if I had the option between switching it off or watch the screen light up and down like a broken lamp, I'd turn it off in a heartbeat.

Someone started a petition for this matter: http://chng.it/Pb2t7TSxwM

Help spread the word.

Don't see how this topic can be marked as solved as the problems still very much exist. Firmware version 1251 tried to tackle this problem but now we get a black flash in the subtitle region. This is even more annoying imo.

It seems that now (UE65NU8072, 1251) the brightness of the subtitles varies depending on the maximum brightness in the scene, so it should not brighten the image - but sometimes it looks weird. But I do not understand why the subtitles must be so glowing, if the user could choose gray as the color of the subtitles, it would solve all the problems...

It seems I am not able to re-open this again. I would suggest you to create another one if you want to make it more visible. I have been tracking the US forums myself and seen that Samsung does not even react to the forum posts so I don’t think it makes a difference really.

Them not answering is a scandal. We paid thousands of dollars or euros or whatever to get the best QLED of 2018 and we get treated like this.

This is infuriating.
