So changing brightness from 50 to 54 after autocal is normal?

You should not have to change anything. Leave Contrast at 85 and Brightness at 50 before and after the calibration.

When I perform the DDC reset the brightness visible shifts and crushes. Autocal doesn't fix it.

This is not the same as your Vizio. Leave Contrast and Brightness at their defaults pre and post calibration if you are going to use AutoCal. It is required, not optional.

Huh? Autocal doesn't fix the crushed blacks when I leave it at default. You are saying this is normal? I don't see how this is normal because I can see the crushed shadow detail with all content if I do not raise brightness to 54 after autocal is completed.

Prior to DDC reset the brightness pattern shows the default of 50 is correct. Flashing Lines 17 and up are visible. Shadow detail in content is visible.

When a DDC reset is performed with brightness at the default of 50. I can visibly see the shadow detail crush. Bars 19 and lower become invisible.

Then after performing autocal with brightness left at default of 50 the shadow detail remains crushed. Bars 19 and lower are still not visible.

Watching content I can visibly see all shadow detail is lost being merged with black. Is this normal? Everything I have learned about calibration tells me this is not normal.

I don't require you to repeat what you already said. I'm only looking for answers to the questions I asked.

OLED panels take fairly large number of hours to gain sensitivity to the lowest input signals. You have the tools to repeat the calibration after about 200 hours of normal use. (not test patterns) At that time, most of us see low signal sensitivity improve. If is not up to your standards at that time, you may still be in your return window.

Maybe I'm not explaining things clearly.

The native picture modes uncalibrated out of the box new setup without any modifications.... Phew. Is not crushing blacks. Shadow detail is perfectly visible as is shown by a brightness test pattern. 200 hours will not make this look any better.

Are we on the same page?

Now when I go to calibrate my TV with autocal the instructions state to leave settings at default when performing a DDC reset. A DDC reset is required to perform an autocalibration. The act of performing this step immediately deteriorates the shadow detail performance of the TV.

We good so far?

Following the rest of the instructions perfectly. Completing the autocal without changing any settings does not remedy the shadow detail lost from performing the DDC reset. My only 2 options at this point is to raise the brightness manually to 54 or factory resetting the picture mode to the defaults. Resetting to default should not be an improvement over a properly calibrated TV, but yet in this case it is.

The information I'm giving does not indicate a panel aging/breaking in issue. It's either an issue with the TV, Calman or both. Brightness and Contrast are not being adjusted by the autocal after being broken from the DDC reset.

D-Nice didn't answer my question and gave me redundant information while implying I wasn't following the directions when in fact I was.

You do understand that nobody is required to answer your questions. After reading your comments regarding D-Nice's attempts to help you, I can't imagine others will be lining up to do so.

I never stated anyone was required to answer my questions. I willingly help many people with useful information on these threads without any expectations in return.
Please explain how D-Nice attempted to help me? He didn't answer my questions and gave me redundant advice. I don't know about you, but if I walk into a conversation and don't understand what happened, the last thing I would do is give my 2 cents that is redundant to the subject at hand. Help is useful, not redundant.

Wow, I don’t understand the responses here. This certainly seems like an issue if the Calman Autocal process produces black crush where as the factory defaults do not. skschatzman was merely asking why this was happening and provided a clue that raising the brightness level to 54 appeared to “fix” the issue. They were wondering if this was something that should need to happen or an obvious clue something was wrong. Nobody seems to be answering that question and repeatedly staying, “please don’t change the value from 50,” doesn’t help since leaving it at 50 produces an incorrect result.

I do agree the value should definitely be left at 50 during an automated calibration. The brightness value likely isn’t “the problem” but just a clue demonstrating that black crush is occurring.

I'm glad someone finally understands what I'm saying. Was beginning to think I was getting dementia. Still waiting for Tyler to respond. I may also try calling Portrait/LG tech support.

We have not seen any reports of this behavior on the 2020 CX. Which firmware version is the TV running?

I can't count how many times I've been the first to discover new issues in all kinds of tech. I swear I'm being stalked by gremlins.

I'm down for any suggestions you may have.

What happens if you do a PM reset, not a complete factory reset?

Resetting the picture mode returns it to it's factory settings. The crushed blacks issue goes away, but also removes the required changes by the DDC reset. Performing another DDC reset brings the issue back. It's a back and forth game with no end.

Tyler is having a look at it and will keep us posted. I'll just enjoy the stock settings for now. The TV looks amazing. I was fortunate with no detectable uniformity issues. Hope I don't have to replace it.

So you are checking brightness after DDC reset in the middle of a calibration? Why? That pust the set in an abnormal state, right?

Not exactly. The first and second time I performed a calibration I did not insert a check stop. After the calibration was completed is when I starting using verifying methods. One of those methods is checking the Brightness and Contrast accuracy. This is when I discovered the issue. Then I backtracked my steps to find out when this first occurs. Checking after performing a DDC reset was one of those steps and where I discovered the cause of the issue.

I've not seen this yet. I know you did a pixel refresh correct? This usually fixes and or improves this problem but what you are describing is something where the 1DLUT many not be loading correctly and again i've not seen this. Let's see what Tyler comes back with.

Update: SDR crushed blacks autocal issue.
Tyler reached out to me to confirm my findings that LG was able to reproduce. SDR auto-calibration(at least for my model. lg-oled65cxpua/FW:03.00.60) is not viable for now. The good news though is HDR-10 and DV auto-calibration worked flawlessly. I verified my results with mascior test patterns.

Tyler says more information will come after the holiday weekend.

If they, LG and PD, were able to reproduce the issue, why would you be negative that they wouldn't fix it? Send to be a major issue for anyone owning a CX.

I know you're not new, so I'm surprised you need to ask. Experience over the last two years with similar pledges in the past. Also I was not negative, I was BALANCED. That's why I said "We all hope it'll be fixed".

Every problem I have experienced was fixed. Some have taken time but it was fixed. That's my experience.

I have to jump in here.
So if it's a CM related problem then i agree, they fix most or all of the bugs eventually. But if it's something to do with the TV then we need to wait for the manufacturer to fix the problem on their end and that doesn't always happen.

My personal take on this is, and i have no "inside" information, i think some of the problems we see like the slightly raised blacks in HDR that you need to see a with jeweler's loupe might not be easily fixable without messing up the totally of near black processing on the older sets which is why we might not be seeing a fix. You always have to weight benefit vs risk when making a change.
