What does this mean? I don't think C8 converts HDR10 to Dolby Vision.

Thanks for the info. Will look into the 65. Hopefefully it doesn’t look “out of place” in the apartment.

Will the prices of electrical appliance go up after sst? If it’s significant then I’ll buy it before SST kicks in. Thanks

Oled TV prices are expensive, any price increase by % will make the price increase very noticeable as compared to cheaper items. I would advise to buy before SST kicks in

What the cheapest price of LG 65 inch C8 did you find? The cheapest price which I saw is 13999 at Best dengki one utama.

SST does not mean prices will immediately shoot up 10%. Calm down guys.

DTM (Dynamic Tone Mapping) of C8 can analyze the meta data of HDR 10 scene by scene and tonemap the greater difference of mastered display to playback device into something more accurate than typical HDR10. The result is similar to HDR10+ /Dolby Vision



You also missed one word , I said Dolby vision - alike ,of course it is not going to miraculously transform from SMPTE ST 2086 into the SMPTE ST2094 format of Dolby vision.
And the end result ? If we are going to be extremely finicky here , it is not going to look exactly the same as natively mastered Dolby Vision content but it is close enough.



Here is a comparison between a W7 and C8 with Dynamic Tone Mapping on , the C8 is much more capable of tonemapping the area surrounding strong light sources , because most TVs don't usually reach the required nits to display it (4000 cd/m2 in this case ). It is very identical to what Dolby Vision can do.


Left is W7 , right is C8

I misread the statement as Dolby Vision - HDR alike...

2017 models also have dynamic mapping of HDR which is called Dynamic Contrast . The algorithms are tweaked so it's a matter of preference on what is correct.

The thing about tone mapping is that there is no standard on gamma manipulation. There is no wrong or right. There will always be limitations of the HDR implementation of OLEDs as the presence of WRGB pixels instead of RGB is already against how white light is presented. Even though the LG OLEDs can do close to 800nits, colour is not correct past 400Nits due to the W pixel being used to generate the additional nits past that.

I can explain further but it's of no consequence anyway. In this sense Samsung is right about colour volumes of quantum Dot based LED backlit LCDs .

ST2084 vs BT1886 is different as in 1 is relative and 1 is absolute. However HDR is supposed to be used for specular highlights above 100nits so technically if mastered correctly the only difference shd be in those but that is not really happening in these early days. It's improving now but it will take some time to get there.

The ace that the OLED has is that it allows for true blacks so technically the same effect can be had but due to the improper standards it's a mess now.

Thanks for the info guys.

Reporting in with the C8T 65"

Several questions if you guys don't mind

1) Any way to reduce the brightness of the subtitles?
2) The technicolor colour preset is kinda awesome but have to dial down the brightness a little bit? Also, what's the difference between OLED Light and brightness? Seems similar to me..

Brightness shd be kept as default. If it's too bright, use OLED light to control light output.

1) Lower OLED light.

2) Brightness is contrast, OLED light is backlight aka luminence output. For SDR, you should lower your OLED light in accordance to your room's lighting. I've found that having at around 40-60 for most moderately lit rooms seems to be the sweet spot for most users. I personally have mine at 35 because my room is dim most of the time and also to minimize ABL fluctuations (which is much more noticeable in a dim or dark room). For HDR, it is default at 100 and that's where it should be.

Finally home after 6 days on the road holidaying to kota bharu and hatyai having to watch 32inch tv in hotel rooms... talk about torture

now where's my remote

Can I play 4k HDR content on Youtube via Chromecast Ultra or must it be using the app on the TV?

Both shd work. The built in app works fine btw.

Thanks man!

Btw, do I need to like enable HDR in the TV or something? I also assume all the picture settings like OLED Light,brightness would be adjusted accordingly as well?

If the video source do support HDR , it should automatically be turned on .
Most of the time , Cinema & the ISF / technicolor mode are accurate enough , so you do not really need to adjust these settings too muich .



Under HDR settings , just leave your OLED Lights to max .
The OLED Light settings on LG OLED TV 's Dolby Vision mode is a little special , so just leave that @ 50.


Yep , I am aware of that . In fact I have mentioned that on previous page as well , it is baked into the dynamic contrast from last year's model.
But in this case most people shouldn't turn it on , because the dynamic contrast adjustment will cause some of the fine details to vanish.

It's similar to contour banding improvement this year , combined with mpeg noise reduction settings , yet another setting most are hesitate to leave On. I know all the video purist are straying away off it , but we have seen how awesome the smooth gradation from Sony TVs can be . The LG's A9 version is just as capable , if not surpassing it . It does comes at a cost of some little fine shadow details , I can live with that.





I agree with you , being no right and wrongs . But all of us have preference , no ? Personally I just can't get used to the Sony OLED's approach to their tonemapping . Some people are particularly sensitive to graphical details . LG's OLED is just excellent at making these highlight shine , where on Sony's side , the white clipping effects are too heavy , even if the object end up to be brighter.

And sadly it is as you said , color volume does remain a struggle for all the OLED due to the wRGB Panel
But again , human eyes are vulnerable and poor compare to many animals . We can perceive more colors and details in the darker zones than white , blinding highlight area .
Your tools can measure more values at higher luminance , but can the average joe's untrained eyes perceive all these difference ? 500~nits in a dark room , I already find myself struggling to stare at the edges of sunlight on the screen . To actually notice much more details and colors would be quite a challenge . At 1000 nits ? I almost can't tell if the center of that sparkling dot was of white or blue .

I am not saying it doesn't matter because the color difference is definitely there , but how big of a difference it makes with an untrained perception? . Especially when most of these specular highlights that are mastered at high cd/m2 are white lights.

That is also why OLED panels , despite of lacking the peak brightness / color volume of those 2018 QLED , the perfect black level will ensure OLED remain the most impressive HDR experience in the market for now.

There are some points in this post that I would like to rebut and probably some points that I want to hv technical discussions around these to see if I can educate people here and other points that I want to re-emphasize. Will write more when I get to a proper computer.

Most posts here and in the AVS Forums tend to be about how to get cheap displays and how great the pictures look but it's important for people to understand how the technologies work and their limitations and strengths.

Hi, sorry if its a noob Q. But is this true for OLEDs nowadays? That means the resale value also drop significantly?

quote "As for drawbacks, one widely cited problem is that OLED displays don't last as long: degradation of the organic molecules meant that early versions of OLEDs tended to wear out around four times faster than conventional LCDs or LED displays. Manufacturers have been working hard to address this and it's much less of a problem than it used to be. Another difficulty is that organic molecules in OLEDs are very sensitive to water. Though that shouldn't be a problem for domestic products such as TV sets and home computers, it might present more of a challenge in portable products such as cellphones."

Just got my C8, short impression was very good however maybe cos I put too much expectation on Oled it didn’t provide a very big jump (for me ) upgrade over my KS7000. On sports the Samsung does provide more impact owing to higher light output.

One thing though ,when playing video thru USB , those high bitrate files still gives the tv some problem like occasional stutter. I thought better processor power would eliminates this since my Samsung KS7000 also got same problem.
