The problem is not exclusive to just C9 .


It is a " problem " for all of the OLED screens because the OLED pixels response times are near instantaneous .
This caused the pixel which has finished transition to stay on the screen for longer than LCD TV , hence causing the stutter effects you are experiencing .

Normally it shouldn't be a problem for stuff like Car races or Sportshows which are mastered at high fps .

The movie and TV shows industry are still getting stuck at the good old 24P .

We have had several experimental ones such as Will Smith's Gemini Man but it was poorly received since most people don't really like overly smooth effect especially when they are watching it on LCD screen .

Which is why I think it is acceptable if OLED owners want to turn on frame interpolation features on their TV . Ya ya I heard Tom Cruise asked you to turn it off but for LCD TV it is simply too much ( fake ).

Try this one .

Not 8k now but 8499 .

Not at 5000 hours , no .

I have measured a 5000 hours + C7 before , not very much of a difference . If anything it was a wee bit brighter .
The organic material will change but as long as the aging of the whole panel remain uniformed there isn't anything to worry about .

The main problem with buying second hand OLEDs is you don't know what they were playing on that TV , they could have randomly downloaded some crappy youtube HDR videos with a lot of watermarks and leave the TV looping on that .


Supposedly LG claimed that the panel will lose 50% of its brightness after 100000 hours of watching but that was many years ago . The subpixel structures have been improved several times after that .
Unless we are talking about the 77 " where they have been using the same screen for years .

Unfortunately , Sony MY told me they are not interested in the " smaller " market for premium TVs .

If you are interested in checking out the smaller display they have plans to bring over the more premium FALD in smaller sizes like the X90H which can reach a peak of 800-1000 nits .

We also have a new HDR king in town from Samsung this year , where that 65" of Q95T can reach a whooping 2300 nits . (1500 nits for 55" )


Isn't this an LG OLED Thread ? Though it is kind of going offtopic thesedays and this thread has become premium TV discussion place in lowyat .

Between the entry level models it is decision of picking your poison. Just pick whichever that appeals to you really .

So , not much of a good news . LG has just confirmed to me they will NOT be releasing smaller size (49") of CX in MY . They will proceed to launch the rest of the line up in Q3 .

Same goes for Sony .

Those numbers are for reference only .

Every TV has its own variance despite being the same model , which is why you have to take its measurement before you start calibrating .

Yes .



Rtings always put emphasis on price vs performance first .


An addition of 200 cd/m2 of headroom on a self emissive screen , is a worthy investment .

Remember you are on an OLED TV , everything start from 0 .
The dynamic range shifting between pictures also have a stronger impact than LCD .

More brightness , less tone mapping needed . Less tone mapping needed , more brightness and textures are preserved .

This post has been edited by Convael: Jun 18 2020, 09:43 PM

No .

For HDR10 perhaps . How do you use customized Tone mapping with Dolby Vision ?

The stutters are not that big of a deal , it is something that happens to every OLED TV ( Including Sony's OLEDs ) during the scenes of panning shots .
Panning shots are not exceedingly common in movies or TV shows anyway .


OLED screen as a whole work really well with high frame rate content .
I have seen both TVs yes but comparing them side by side no .

Sony will always have the best motion performance in general .
How big of a difference comes down to if you are using those motion features , as long as they can do 5 : 5 pull down at 120hz correctly it shouldn't be a major concern .


High end LCD with 120hz refresh rate is taking it a lot easier because they don't have to render 24p movies @120 hz since LCD is based on hold and display , a.k.a active matrix .

They can do do 24 hz for 24p which is basically the same . That means these 120hz lcd shouldn't have much of a problem with judders assuming the engineers know what they're doing .

White points can be subjective at times , depends on the room condition .

D65 being the most common one we used under most circumstances .






There is no perfect white point , even with D65 there are still some inaccuracies in the way we perceive colors , which led to LG changing its white points in technicolor mode while ago .

This post has been edited by Convael: Jul 7 2020, 08:52 AM

But the "warmness " of WHITE is always closed tied to the white point you calibrate the screen to , so they are actully kind of inseparatable , subjective or not .
And when you said " deeper " , I assume you mean depth of the pictures . Again , another aspect that is closely related to the gamma values .

It is hard to talk about the two without mentioning the other two , especially if you are on the perspective of calibrator .

Except that channel is about as reliable as China telling you they are not stealing your private information

Use OFF , scale down OLED LIGHT to around 40 for SDR .


Peak luminance controls the amount of light from the white-boosting subpixel .

Typically with peak brightness ON , you should get a range of brightness up to 330~400 nits from 0-100 [OLED LIGHT] in SDR .
OFF , you still topping out at 250 nits , more than enough for everything in SDR .

This post has been edited by Convael: Jul 9 2020, 06:03 AM

If the peak brightness setting is on , it will typically hit 100 nits at 20-30 .

If you leave the peak brightness setting off , the range of luminance will be decreased so 100 nits will likely land at around 40-50.

100 cd/m2 is what the typical SDR TV shows are mastered at , 120 cd/m2 if you want a little bit more highlights and pops .

This post has been edited by Convael: Jul 8 2020, 04:28 PM

On = max of around 400 cd/m2
Off = max of around 250 cd/m2

Low / High = somewhere between 250-400.


Who is this " everyone " you speak of ? And how do you know which TV model they are using ? B9 ? C8 ? C9 or CX ?

I am not saying you should definitely be using the exact same setting . Obviously you also have to consider the factor of panel variance here .


The C8 used to be able to hit 400 cd/m2 in SDR mode but a patch landed last year cutting down the peak brightness in SDR to around 300 cd/m2 .
B9 is quite a bit dimmer than C9 and CX as well.

My C8 is calibrated to 100 cd/m2 at 32 OLED lights , I don't have a C9 but I have calibrated one at around the same number too [Peak off].
It is what it is , I don't measure peak brightness in SDR mode either .


If you are that obsessed with hitting the exact number you should be getting a colorimeter then .
Without that , the best you can do is only from estimation . Else , the range of 20-40 should be working fine for most people .


The peak brightness setting is unnecessary for SDR mode anyway , since SDR content is only using the colors within the rec.709.
The OLEDs should be more than capable of covering the color space of rec.709.

Jeez , you must be new here .

How did I conflict WITH myself ? I am giving you a suggestion .


I might not have owned a C9 , but I have measured a C9 way before rtings published their numbers .

Since You don't have a method to measure the numbers , so if we go by my estimation of 100 nits - 32 on an OLED , with PB Off the numbers should have spread even further .
Therefore I was giving you a suggestion of setting between 40-50 .

The peak brightness numbers have never been changed in the past 3 generation for LG OLEDs , so I don't see how did I conflict myself .
If we go by your logic , I must have " owned " the same exact model as you to know what I am talking about , then I assure you many of these TV reviewers will be jobless since they never actually own most of the TVs forever .

Not saying saying your dear calibrators from whatever forum you are reading is wrong .
Who knows if they are getting that special snowflake unit ? Which they often are , like the one rting got for C8 which can get up to 1000 nits ? But mine is " only" peaks at 760 .

The key here is figuring out what is the max brightness you can get on your TV in SDR mode . Peak brightness off deduct the overall brightness by roughly 33% .
Please , do use the numbers suggested by your friends in the forum . I have already explained the reason behind my suggestion , in great details and I standby that .

But if you are so desperate to get the numbers to land exactly at 100 cd/m2 , you need to get a colorimeter . Even if it is the same model , your numbers may end up to be higher or lowers than the others .





I used to rent a Klein K-10SF (older model ) and K10A from BSM , a deposit of RM15'000 is required . Or you can import them for around RM30'000 .

I am also using X-Rite i1Publish Pro 2 which I am still using for monitors and other colors related project , cost around RM10'000.

Which is completely worthless .


You have to make sure the phone camera accuracy is of the reference settings ( which I can assure you it is not , far from it ) to get any decent results from it .

Since there is almost no way to calibrate your Phone's Camera using conventional method , this is not really better than people trying to guess which colors are accurate with their eyes .



This post has been edited by Convael: Aug 20 2020, 01:23 PM

What do you think they are calibrating the white balance for ?

White balance affects the COLORS temperature . Once you get the white balance correct , the colors will mostly fall into line . After that you will proceed to finetune the 6 colors .

How do you think the phone app can magically " tell " you the reading ? via Your phone camera of course .
Since this process is completely dependant on your Phone Camera , You ought to realize how accurate your Phone Camera is before you can calibrate anything .

A calibrator tool should be of the reference settings . If not the process should not be called calibrating , it is called guessing .

As for the APP you are showing me , that THX app merely provides calibration patterns for your display . It doesn't REPLACE the colorimeter / spectrophotometer .
You would still need a colorimeter to read the numbers . The color grab app , however is trying to replace the spectrophotometer with your phone camera .

Apple TV app should be launching on LG's webOS very shortly .


Update : the app is already available on LG's content store.
