I do have a have a serious disappointment related to HDR content - especially Netflix while using subtitles. I do have firmware version latest. I've put local dimming to Low but even with that not very happy with the result. I'm afraid there's no solution. This problem has been around since models and they do nothing to fix it. Return the tv if you're still in time and get a different brand.

I don't notice your problem. But, I have different settings.

Samsung Q90R Dark scenes in dark room issues.

I think my settings include Movie mode. I found recommended settings at ratings. I have The exact same problem, and its super annoying.

Why dont just let us choose on or off?

Fixed [Solved]: Samsung Smart TV Brightness changes with subtitles

Im thinking of returning mine but i just hate The hassle of doing so. I think is related to Netflix mostly and the way they draw the subtitles and just to norrow down the issue - on my native language if I choose the language the subtitles are way too bright. If I choose French - are more acceptables. I think the issue is not specific to netflix. That combined with high contrast titles prompts the tv to make changes to brightness. Their tv apparently don't have this issue. I set my dimming to low, and have now watched both The Witcher and The irishman and havnt noticed any dimming problem whatsoever But when i watch Lost in space and The new "Harry Potter" movie i notice it in many scenes, Its very different movie to movie it seems.

But i agree, very tempted to return The tv right now if no fix is in sight. Westmere avx dont know if this was done in post processing or it is somehow as intended but not really enjoyed this season. I Will post a video that shows The problem, its very obvious in this clip. Sign In. Turn on suggestions.

How do quantum dots work? Check out our deep-dive into the technology for all of the details. The LCD panel β€” essentially millions of tiny shutters that open and close too quickly to see β€” in conjunction with color filters, create the picture you see by letting just the right amount of light and color escape and reach your eyes.

Instead, it refers to the fact that every single pixel in an OLED TV is also a teeny, tiny LED light β€” but one that is incredibly thin and can produce both light and color in a single element.

There are several advantages to this design, but most would agree that when it comes to OLED TVs, the biggest advantage is the superb black level that can be achieved. When the pixel is off, it emits no light and no color, making it as dark as when the TV itself is turned off.

It sells those panels to its sister company, LG Electronics, which uses them to build some of the very best TVs you can buy. The result? Contrast is the difference between the darkest part of an image and the brightest part. But is it noticeable? Because they use separate backlights instead of relying on each pixel to create its own light these LED backlights can be made incredibly, achingly bright.

OLED once blew all the competition out of the water in this section, but the use of quantum dots in QLED TVs have allowed it to inch forward in terms of color accuracy, color brightness, and color volume β€” according to Samsung, which claims that a wider range of better-saturated colors at extreme brightness levels are an advantage. Response time refers to the time it takes for a pixel to switch from one state to another.

The faster the response time, the crisper the image, especially during fast-action scenes. Though there is likely a speed of response time beyond which the human eye is incapable of telling a difference, we know from standardized measurements that OLED TVs are way faster β€” orders of magnitude faster than QLED TVs. Input lag, on the other hand, refers to the delay between taking an action say pressing a button on a game controller and seeing the result of that action on-screen.

Moreover, the amount of input lag you experience has little to do with one display technology over another, but more to do with how much image processing is happening on your TV behind the scenes. Refresh rate is another category that will inherently matter more to gamers than casual viewers. Under normal circumstances, a TV will use a refresh rate of 60Hz or sometimes doubles that β€” Hz.

With QLED screens, the best viewing angle is dead center, and the picture quality diminishes in both color and contrast the further you move side to side, or up and down. OLED screens, for comparison, can be viewed with no luminance degradation at drastic viewing angles β€” up to 84 degrees.

OLEDs have come a long way. When the tech was still nascent, OLED screens maxed out at 55 inches. OLED, on the other hand, is, but you would have to be extremely unlucky for it to happen to your TV, even if you left a static image on it all day and night β€” repeatedly. That occurred when the phosphors coating the back of the screen glowed for extended periods, causing them to wear out. If you burn a pixel long and hard enough, you will cause it to dim prematurely and ahead of the rest of the pixels, creating a dark impression β€” but you would have to essentially abuse the TV to achieve this result.

Go too far, and your irritable eyes could eventually lead to sleeplessness, which itself can contribute to a whole range of health problems in the intricate workings of the human body. S market. QLED comes out on top on paper, delivering a higher brightness, longer lifespan, larger screen sizes, and lower price tags.

OLED, on the other hand, has a better viewing angle, deeper black levels, uses less power, and might be better for your health.

That is, of course, until the next generation of display technology comes along. But microLED is still a very expensive technology, and only useful for those seeking mammoth display sizes of inches or more. How to figure out what size TV you should buy.

This setting changes the brightness of the picture depending on what is being watched. When going from a program to a commercial β€” or vice versa β€” the brightness level would noticeably change.

This setting automatically dims the TV based on the ambient light in the room. When the sun started to set, and the room started to darken, the TV also dimmed itself. There is a shortcut solution that can save you a few steps. Please note that you will need to go through this process for every input on your TV, including when you are using the Smart TV functions and apps.

With the government mandating lower and lower energy consumption for all electronic devices, manufacturers need to find ways to meet the standards. Not only is the government mandating changes, consumers are looking for and basing buying decisions on the Energy Star sticker. To satisfy both the government and Energy Star requirements, manufacturers are devising creative ways of claiming lower energy use. Lucky for us, there are ways to defeat the more invasive features.

This was a hard way lesson for the tech that did this install. Hopefully, the pain he felt will mean an easier time for you. Happy Viewing! About Brian Hill Brian Hill is a home theater enthusiast who has an extensive background in sales.

Under Picture mode, Dynamic shows clean blue color, Movie is yellow murky tint; all 4 Dynamic, Standard, Natural, and Movie; energy star logo next to Standard, but all 3 are affected by auto-dimming, except for movie. This cheats customers out of quality. So all Samsung tvs and all UHD on display in store are fake and illusional because of energy star.

When Smart tv are no longer samsung stupid when its IQ reaches 50, they should sell better. I suggest setting the TV to operate in this mode. The settings can change depending on which input is being used. Once you have verified the picture mode setting for each input, then double-check to see that the eco settings are set to off in the picture mode. Do this for each input being used on your TV. The settings sometimes appear to be off but only in the picture mode being watched and for the input being used.

I got the TV a week ago. And recently noticed all movies netflix in dark room look too dark. We watch alot of movies in the dark and this is a huge dissapointment, not only that, but if I increase the Local Dimming to "HIGH" then the subtitle gets too bright which gives a darker effect to the whole scene when the subtitle appears. Like wtf samsung?

And it's even worse with HDR content on netflix and youtube. These are apps through the tv itself. I've tried all settings and i cant hide the issue if i dont take Backlight to MAX, but i cant do that since it will make me blind in the dark whenever i pop up the tv Menu. Any fixes? Miles C Musket Active Member. The backlight needs to be on the highest setting for HDR to be displayed correctly. Foster Well-known Member.

Are you only having this issue with HDR material? Or even on SDR?Couldn't agree more. This dark flash in the subtitle area is very annoying apart from the fade-in effect in terms of brightness. This makes me want to sell the whole set and look for another brand. Please Samsung take a look at this issue. This is not something you would expect from a flagship device q9fn 65". They have their own dimming "problem". Kind of like what the plasma tv's had. I would dig a little deep before making any decision.

Only found the dimming issue from last year that has been fixed within a month with new firmware. OMG What a difference Its a few levels up.

No more dimming problems, the picture is more accurate and the motion is far better. For any of you that still can return your tv, do not think twice! When you switch off Local Dimming in Service Menu you dont loose brightnes option. Will be still active and working.

QLED vs. OLED TV: What’s the difference, and why does it matter?

You lost backlight control. Will be locked arround and when you be want brighter or dimmer screen, not be working anymore. I have at the moment my backlight level to 50 watching tv.

Backlight setting is active as it was and lets me tune it as i wish. Turning off local dimming from service menu it solves the problem with the brightness auto changing when watching mainly movies with subs in HDR. The Local Dimming menu item disappears when you turn off the local dimming from service menu and that's the only thing that disappears from the menu. All other options are still enabled. I did it yesterday and everything i say is exactly as i wrote in first message. At least for my Tv.

Did you mean:.The problem is all this QLED goodness comes with a lofty price. So what can you do if you fancy the inherent benefits of QLED but don't have the necessary readies?

That's where the Samsung Q70R comes in: it has those metal-clad Quantum Dots for purer colours, it has a direct backlight and local dimming, it has the AI chipset, and it has the comprehensive smart platform. If you're thinking there has to be a catch, you're right: the Q70R uses fewer dimmable zones than the more expensive models, meaning there can be backlight foibles, and it also drops the Q90's filter, thus viewing angles aren't as supreme.

There's also no One Connect box to separate the connections to a separate box, so if you're hoping to wall-mount then other options in Samsung's QLED range might make better sense. Still, for the budget conscious, the Q70R offers heaps. The Samsung Q70 goes for a minimalist and unprepossessing look that is commensurate with its lower price point.

There's essentially no bezel around the screen and a simple black trim around the outer edge. It still reflects Samsung's degree design ethos with a ridged rear panel that adds a bit of visual texture. The build quality is reasonable, but relies heavily on plastic for its construction.

On the plus side it's lighter, which makes wall-mounting easier. The panel otherwise sits on two metal feet that simply slot into holes on the underside. The feet are quite far apart, so bear that in mind when installing the Q70 - since there's no One Connect box all the connections are at the rear of the panel.

There's also built-in Wi-Fi and AirPlay 2. You don't get the classy metal remote found higher up the range, but you do get two controllers in the box. There's a standard zapper with all the usual buttons, and a stripped-down wand that is more ergonomic in design - it has all the main buttons, plus a microphone for voice control, along with direct access for Netflix, Amazon and Rakuten. The Samsung Q70 might not boast all the new features found further up the range, but it does include the new Quantum 4K chipset with AI enhancements.

The processing is optimised for 4K resolution xand applies machine learning to upscale lower-resolution images.

The Q70 analyses and processes images using a database that's periodically updated via machine learning algorithms. The processing doesn't just upscale lower resolution images to match the 4K panel, it also enhances them by applying detail creation to improve the texture of objects, and reduce image noise where necessary. There's also an edge restoration feature designed to remove jaggies and create lines with precisely-defined edges.

This is combined with about 50 local dimming zones - which might not sound like a lot, but Samsung's local dimming algorithms are so good that the results are often very impressive.

This suggests it can reach 1,nits of peak brightness, but we actually measured it at nits maximum. The Samsung Q70 might not have the black filter and wider viewing angles of the more expensive models in the range, but these omissions can be mitigated with some sensible installation choices. It might seem obvious but avoid nearby windows and that lack of a black filter is less of an issue.

The same goes for the viewing angles: if you sit towards the centre then it's no big deal, and who watches telly from steep angles anyway? Another tip is to pick the best picture mode.

Fixing a Samsung TV Dimming Problem

The default Standard looks good in the daytime, with its bright and punchy images, but the Movie mode is designed for night-time viewing.I bought the Q90R on Black Friday and just yesterday I began noticing a darker cloud spot in the top middle right of the screen. My wife and I watched last night and even she commented that it looked like a storm cloud was approaching. Not only this, but there is a noticeable flicker to this spot when showing brighter scenes.

I already have the eco mode disabled and always have it in movie mode; so I'm not positive what else could be done. Does anyone else have this issue? Pretty upset the top of the line Samsung has this sort of issue. I'm sorry to hear that, does this occur on all sources?

Also does this occur during the picture test? If this still occurs after a restart then this will require service depending on the warranty of the TV you have two options if the TV is out of warranty you can use the link below to find a service center in your area. Or if the TV is still in warranty you can send me or any of the other moderators a private message with your full model and serial number and we can get you set up for service.

Yes, it unfortunately occurs on all sources and also occurs in the picture test failed all 3 tests. It should still be under warranty as it was purchased 4 months ago.

I love the tv, but it's a little ridiculous to shell out that kind of money for the top of the line product and have these issues. I'll DM you the model and serial numbers. Sign In.
