HDR is not a color space, it's a brightness ratio. WCG is color space which compliments HDR.

Aiya, too fast tell the answer, I just want to guess myself. Haha!

perhaps next year OLED 4K or 8K will face the real price war from Samsung...

LG came with new panel today.
after change still not perfect, still got dead pixel and misalign pixels of the left.
only notice my old panel banding so badly, new panel clear from banding.

LG will order another new screen and come and fix again

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

Do ppl use peak brightness setting for SDR? I am asking cos the TV installer told me to set to high but it seems like that just make the picture unnecessarily bright??

Standard sdr peak brightness for dark room only need 100nits. From bright room, you can increase the brightness suit your environment. I use auto brightness setting to let tv automatic adjust brightness .

How will I know what OLED light value to put in to get 100 nits for dark room?

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 .

Will try 40 OLED light in bright room preset setting.

I did read on AVSforum C9 calibration thread that most people get 100cd/m2 at around 19-23 OLED light though depending on panel variance? Isn't 100 cd/m2 the reference for SDR movies?

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 .

I am getting conflicting info seems like. Almost everyone in the calibration thread says to turn off peak brightness and set OLED light value to 20 - this gives them 100 cd/m2.

But you are saying you can only hit 100 cd/m2 at that OLED light value IF peak brightness is set to ON? but if it's ON, then what setting should that be at? Low or High?

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.

Damn.. I was really looking forward to the 48" for my pc... I guess QLED is the only alternative..

I'm really disappointed by my IPS ultrawide because I have it next to my 55 C7 and the quality of the picture is so different

The C9 calibration thread at avsforum. So they are all talking about C9 model. I am aware there are variance in panel, that's what I wrote few post ago.
You are the first person that is saying OLED light between 40-50 only give 100 cd/m2 if peak brightness is set to OFF. But now you conflicting yourself again saying your own C8 which is not C9, you have it set at 32 and is already at 100 cd/m2. You did not mention you are using C8, so all the settings you said is pointless for me then.

I want to ask what colorimeter you use? I want to buy one.

of course if you compare IPS vs OLED
OLED not suitable for pc static images unless you always have moving pictures like movies or gaming

no choice, you need to wait for microLED or samsung quantum dot oled tvs

If you can buy Calman Home for LG software &　 Calman Compatible Meters which list down in website，you can use software to do auto calibration. You can automatic get accurate white balance ＆　color space . More than correct oled light.

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.

Yeah..I was so close to ordering the new Samsung G9 Odyssey..until I saw it doesn't have FALD. Don't know what they're smoking claiming HDR capability withouth FALD haha..and the two monitors available with FALD are all around 10K+.. LG OLED tvs represent the best value right now as long as you're not scared of burn-in (which I don't)

Hey guys, planning to change my old LED Sony tv(2011 bravia models) for the upcoming PS5. Personally I do a lot of gaming and netflix while my family watch astro most of the time. I've found an attempting deal for 55B9@Rm5499(+10%cashback voucher). However, I've noticed that some pro in this thread mentioned that B9 need a lot of calibration works which I don't think I'll put effort on it XD. So my question is will you guys take this deal or wait the price of C9 drop a little more? Besides, does anyone noticed why there're so much lesser C9 deal found online lately?
