Wow forced the normal brightness pixels to become dimmer, meaning every 2000 hours the oled tv will be become dimmer leh
*
Not at 2000 hours .

Rtings have conducted a burn-in test awhile ago and as you see from the graphs the brightness still remain at the same levels even after 10000 hours .
The color gamut , however has degraded a little but we are talking about 10000 hours of torture tests here .

And they probably have ran hundreds of pixel refresh cycles , manually .


I am sure there are side effects if you are trying to abuse the feature .

Just don't do it if you are not having any problems with the PQ , the TV should be doing everything for you automatically .


Another thing is keep in mind is , don't turn off the power plug of your OLED TV instantly after watching a show .
We do that with our traditional TV but not OLED TVs . The TV needs to be dormant but with power on to run pixel compensation cycles .

I suspect a lot of ppl who had sudden burn-in issues are guilty of this .

Is keeping the power plug on overnight more than enough?

30 minutes should be fine .

The short version of the pixel refresh cycles [which happen roughly every 4 hours the screen has been turned on] should only take about 5-10 minutes .

If the TV is going to perform the long version [ for every 1500-2000 hours] webOS will inform you via a notification window before you turn off the TV .

And what I can gather are:
1. Floating black can be solved by lowering the Brightness setting. In this case, I assume it can be fixed with later firmware update?

*
Lowering brightness directly will also crush near black details and mess with the gamma .
No ideal solution until the engineer release a patch .


QUOTE
2. Near black flashing. I read Sony is worst in this aspect and Panasonic the best? So LG in the middle? Possible fix with firmware update?



Panasonic simply has a more advanced 3D L.U.T which can adjust color (hence the gradient transition ) in real time . It isn't something you can just patch in with firmware updates .

I have ran my signature video - GOT S8E3 on an A9 before .
Overall I find LG TV being the worst in this regard out of the big 4 ( not by a large margin and that is despite of what HDTVtest says )
My reason is simple , LG's solution to near black artifacts has cause dithering to become too obvious , it has made the pictures look too noisy at times .
On Sony's TV there are flashing tiles but at least I don't have to deal with the grainy gray .

I actually watched that entire episode for the 300th times on a CX recently . There are less flashing artifacts but the graininess is too distracting .



QUOTE
3. I read Panasonic is the best in this regards. How does the Sony compares with the LGs?
AFAIK Sony's engineers don't seem to be acknowledging the so called black-flashing issue at all , they are putting the blame onto the content's creator .

But most of us are aware , Sony's TV allocates a large amount of CPU power into picture processing , which is why they need a separate chipset for picture processing beside the S.O.C .
( Side note : the latest X900H don't have this separate chipset )

The X1 ultimate chipset upscales picture to higher color bit depth which helped a lot to deal with the fuzziness of dark scenery .
The smooth gradation feature is also far more effective on Sony's TVs than on LG where the effect is too subtle .

There are still major black flashing effects but I find the overall picture cleaner than it is on LG's .
But it is something you can agree to disagree .


LG 's engineers do have a commendable working spirit , who knows if they will work out another patch to iron out the problem ?
My C7 and C8 are still getting firmwares updates from time to time .

Thanks for trying to clear things up for  me. Much appreciated.

Allow me to ask a hypothetical question.  Between the Panasoinic GZ1000 and LG CX. Which would you choose and why. No gaming.
*
Probably the LG CX .

TV bumps into issues from times to times , and I like how quick and responsive LG's team are at tackling problems .

Again that is assuming you are buying the C ( or above ) . I heard the B8 has yet to receive the black-flashing improvement firmware from 2018...

You using the CX?

I read with the LG, you can use the Calman autocal to "improve on' the 3DLUT. Will that solve the problem?

Regarding the graininess. I suppose if you don't sit too near, the graininess is less obvious?

Regarding smooth gradation. I read the C9 have effective gradation but not the CX. You think LG will fix the CX with a later firmware update?

The Panasonic doesn't have this smooth gradation feature, right? And they don't need it anyway and still get the job done?
*
It will not solve the problem , LG simply doesn't apply that much of post processing work in its TV .
There are side effects to come from heavy post processing . If you look at Sony TVs they almost always have higher input latency .


In general most people don't use auto-cal much because it can cause Posterization sometimes among the gradation of colors .
Manual calibration allows for more customization and better finetuning ( and more time consuming ) .

They are mostly used by people who need a large amount of fairly accurate display in a short time such as a conference / event .

The CX has the same smooth gradation as C9 but it was bugged before . AFAIK the issue has already been resolved on the CX series .

Panasonic TVs didn't actually have smooth gradation but they don't need it . From what I know , their HCX engine can do color correction in real time , hence there are less room for errors going from 1 shade of color to another .

HZ2000 winning TV of the year , again . Not exactly unexpected .


Glad to see Samsung is at least getting notable mention in other categories like DTM and video processing , compare to previous years .
So the Q90T [Q95T in MY] isn't just another bright HDR TV .

Try running a manual pixel refreshing cycle . If not you will have to replace the entire panel .

Okay so , we are having another flashback episode of " FULL OF SHIT " here .




Let's see , fitness enthusiast turned " TV calibrator " overnight , checked .

Accusing industry professional , including Darko from CalibrateHD who is ISF certified , a scammer , checked.

Youtube URL links you to his shortenURL website loop so he can makes money from you clicking endlessly on add ons and pop ups , checked .

About the only " good " thing he has done , is riding with the bashing group on Quantum Apotheosis and FOMO [ whose TV Reviews are as good as typical mother ranting on Miley Cyrus Music videos . ]


Personally I would suggest you stay the **** away of these people from light years distance .
There sheer amount of bullshit may wreck your nerve system if you are not careful .


P/S : And friendly reminder , OLED TVs are product of mass production . Thus , unit to unit variance exists and don't bother trying out his WB settings because it may work for him and never work for you .

Just from that picture alone , I would say your tinting issues are pretty mild .
But that is just me looking at picture captured by your Camera , it may look different in real life .

As long as it doesn't distract you in real life watching experience then it is mostly fine .


You can't exactly fix tinting problems but for the mild issues we usually calibrate the screen to slightly above or below the 6500K depends on if warmer / cooler hues are showing on your screen.
But this is not very effective and only serve to mask the issues , it is not a perfect solution .

It is finally here .

According to AVCesar , LG will release its very own version of " professional OLED panel " which can achieve 1000 solid cd/m2 peak brightness like the Panasonic 's HZ2000 in 2021 .
At the same time , Sony and several other brands who bought OLED PANEL from LGD will also be using these screens for their 2021 flagships .


Don't expect the B series to use as it has been nerfed down to the drain in the last couple of years .

It is , the professional here means the OLED panel has extra work done [customized heatsinks] to more quickly dissipate heats generated from OLED pixels .

Question on screensaver

With build in Netflix apps, if we pause the streaming for 2+ minutes, the screen saver will come on.

But if streaming Netflix from a Fire Stick and pause, the screen saver will never come on.

Anyone know why?
*
The screensaver is meant to work only for apps and stuff that are built within the LG TV .
And in this case , the Netflix apps installed in webOS fall into the same category .


Everything on an Amazon's firestick is considered external source therefore the screensaver is not going to be triggered .

Because the source (in your case the Firestick) doesn't go into low power state when left idle for x amount of minutes. As far as the TV is concerned, it's still receiving a polling data from the source that it's still active thus the TV must not engage screensaver mode.

Nothing to do with the TV, it's just how source players don't care for idle power states.

There , the more precise answer .

At first, I thought was just some mild image retention and so I just run the "pixel refresher" feature in the TV. Manual pixel refresher didnt start or couldn't start even after leaving the TV off for overnight.  Error message was the same "TV was switched on before pixel refresher could complete". This bugged me for couple of weeks as I suspected it was faulty and the auto run feature too which eventually exacerbated the issue. The image retention is not noticeable on a total black or white screen. Only noticeable on other colors. Finally decided to call LG and booked an appointment and will incur a RM150 fee. Oh well, I agreed to pay, else what can I do?

Technician came and confirmed what I dreaded most, it's a burn-in. The burn-in was caused by watching Hearthstone gameplays over youtube but no longer than 1hr a stretch as most YT clip only lasts about 10-15mins and I do watch accumulatively a few hours a day of such clips at HDR "Strong" settings and in betweens, ASTRO, movies, channel surfing other YT contents etc.




The techinician noted on the hours used on the TV.  It was 6.7k hours usage and he said this "Sir usually about 7k hours time to change panel." I was shocked obviously. I asked him are you sure about this????? Nevertheless I didn't believe him but he did add that this is the most common issue - burn-in after 7k hours of usage.

I dont know how much pixel refresher could actually fix if it was able to run in the first place, however i doubt pixel refresher could do much as burn-in = change panel.

I did ask the technician about roughly how much to replace the panel. He said for 55", it's about RM5k not sure about 65".  He lost me after that, I lost myself later...

Well I do understand the "fragile"-ness of OLED but but but.... ahhh nevermind. Some might argue that I asked for it for watching too much Hearthstone game plays then again thats not the point is it? Point is, with OLED, you can't watch anything that has static picture e. g Hearthstone hero frame, if you even call 15mins clips long. Speaking of that, I watch ASTRO for hours on end too. The channel logo doesnt cause this burn-in as far I can tell. Why does watching 15min clips of Hearthstone hero frame does?

As much as I love OLED TV, I won't be buying another or even get my panel replaced for RM5K (minimum, as I haven't got the replacement quotation). Probably look at QLED intead.
So let's get a few things straight , C8 is a 2018 model .

Given that you have 6000 - 7000 hours , you have been watching this TV for 8 - 10 hours everyday ?

Within this period , your TV should have ran at least 3 major pixel compensation cycles according to the system. Did you get the notice ?

One more thing and please be honest because I knew a lot of people had accidental burn-ins lie on this . Do you turn off the power of your TV everytime after you watch it [Instead of leaving it on standby mode] ?


The wRGB OLEDs are actually one of the more resilient organic pixel vs burn-in and has suffered color saturation because of that .
Even with 6000-7000 hours watch time , which I can certainly tell you have been using it a lot , You still shouldn't have experienced this .

It is like SSJben suggested , you must have done something to trigger this .

Either leaving the TV to maximum brightness 24/7 or forced HDR on the SDR content , either of which is a silly thing to do .
Or your TV have been skipping pixel compensation cycles since it couldn't complete it before your TV was turned on and off .

I think the Sony's A9J series are going to be a more attractive upgrade than LG 's C1 atm since they have the extra layer of laminated aluminium sheet for heat dissipation.

These professional OLED panel will light up all 4 of the WRGB pixels to increase the brightness compare to 2 from the previous OLED , so it should have better pixel efficiency and color volume as well .



The A9 series are slightly cheaper than the LG's G series in MY .
Also has tendency to drop its price faster due to its popularity (unpopularity) , its 77" A9G went on sale for less than RM16k during 11/11.

The question has been answered several times , the short answer is NO .


If you are that desperate to get an OLED screen , just wait for a little while .
There should be a number of budget OLEDs with downgraded specs available at even lower price this year .



Keep in mind these new gen of watered down OLED will be quite a downgrade from the flagship .

Like someone who sold their 65" C9 to get a 65 " BX , which is silly .

LG G1 Evo is the new keng one?
*
A lot of competition this year in the TV bracket , between these native 12-bit Mini LED quantum dots which has almost 800 dimming zones and the more affordable 60hz OLED .


The new A90J from Sony [which is using the same Pro-panel as G1] ends up to be rather disappointing despite of all the 1300 nits hype [Vivid mode only] .
Post calibration put the A90J down to 750+- nits , still amazing[for a Sony OLED] but probably not worth the extra $$ .

Kind of silly because these Samsung can reach 3000 nits in these oversaturated , over-processed viewing modes , nobody should take these numbers seriously to begin with .



G1 will like launch at May~June with some really outrageous price . We are not getting a 83" , 77" nor the 55".
MY is not a TV key market for LG even if OLED TV is selling pretty well in local since the past two years , they will remain out of reach for most people .


Considering that the cost of production for OLED TV have also dropped in the past few years , I have a hunch LG will eventually use these "pro OLED panel " in their " C " series so you might just want to hold your horse yet .


I don't know if we will be getting 48" this year but I have been pressing my source for answers .
With establishment of 8.5 FAB in China , perhaps they will have quota from the left-over . The bad news is that I was told that even if they are to launch 48" here it will not be much cheaper than the 55 " .

You are right, they don't have 83 " for the G1 yet .

83" is for C1 and Z1 only .
