Well, I just did a search of your posts and the last comment I could find that you made regarding your calibrator was on 01-08-19. You've changed your signature indicating you are no longer waiting for a calibration. It was supposed to be done a couple weekends ago, right? But unless I've missed the update, you haven't said boo about the results. Were you sworn to secrecy? I am curious how much difference the calibration has made compared to out of the box or personal adjustment to settings you'd found satisfying. If you have indeed remained silent on the calibration, I can only presume it's because it made no significant difference. What's up with that?

There is nothing broken in the newest firmware plus there have been updates to give you a better overall experience.

Really no reason not to update.

I don't think he meant search his posts, he meant use the search for this forum and you will find a lot of setting suggestions.

Basic setting suggestions & actual calibration are two separate things. Always wait a couple of hundred hours before getting any pro calibration done.

As for basic menu settings, there are plenty thoroughout the thread.

You can also check YouTube. Donnie Darko & rtings.com have some good videos for that.

Ultimately it comes down to what you prefer in various situations. Do you watch in a dark room or bright room or combo of both. Then there is SDR, HDR, Dolby vision, then cinema, Technicolor, isf bright/dark, game mode.

It's just that the same info has been posted over and over here and it seems that when someone new jumps in, they just ask for the same thing to be posted again. Using the search feature can bring you all the info you may be looking for without members having to constantly repost

I agree. My receiver is the hub of my system and I just have it pass the video thru, untouched and unmodified to the C8, and let the C8 do the upscaling.

I never trust an atom, they make up everything.

Unfortunately he never made it over to the Magic City last weekend, we have missed connecting a couple of times now since the beginning of the year. It would be a safe bet to assume if he had visited I'd be sharing my thoughts with all of our fellow owners. Whenever it happens there will be a couple of posts in the respective threads. No secrecy

I just pn'd back your pm to me. Sorry to hear of your frustration.

I am so happy with my personal adjusted settings in Technicolor Expert I use for SDR. I have never seen a better SDR image on any tv before. Absolutely gorgeous. And the Cinema for DV and TE for HDR OTB default settings are of course even better that I am almost certain that a pro calibration would offer negligible results anyway. So no loss, if your personal efforts have been as satisfying as have mine. The LG C8 is truly pretty near perfect as is!

When I play from netflix app a video that support Dolby Atmos I can see on the upper right side the Dolby Atmos logo, but when I check the video info the sound source writes 5.1 instead of dolby atmos. Is that a normal behavior?

I don't know the cause but it sounds like you already have the work-around: just use Cinema mode.

You mean "is broken". As explained several times now with proof, your TV was supplied to you with firmware which has a very serious bug, which was not fixed until version 4.10.15.

All firmware versions between (at least, but probably before) 3.00.63 through to 4.10.10 have this brightness fluctuations problem.

If you would prefer to keep the buggy firmware, that's up to you of course.

You need 4.10.15 or later to fix the problem. End of.

You can try both ways but odds are the TV processing is better.....

I always thought that Quantum Dots were various sizes of crystals. The size of the crystal dictates the color. They are applied to a screen with some type of liquid binding agent. They basically make brighter colors and more intense colors using less light from the exciter source.
Something along these lines.

Well seems like it is the elevated black issue after all. Now I notice it too in Cinema mode, and across all dolby vision movies. I didn't notice it before because this mode is dimmer compared to others. And it is not just elevated black; the screen is filled with greyish lines running across the screen in a pattern. I think someone mentioned this issue in the elevated black thread. Reducing brightness from 50 to 49 seems to fix the issue at the cost of crushed black, or there is another way which is to reduce contrast from 100 to 99, but I need to do more testing in a pitch dark room, because this issue is incredibly hard to notice unless there is absolutely no light in the room. This happens with both c7 and c8. I'm starting to feel very frustrated with oled.

So many other equipment threads (Denon, JVC, etc) have some reference post which collects together basic answers on settings, firmware, known issues, etc. So it’s a little surprising given the popularity of these OLEDs not to see it here. And searching for recommended settings returns over 170 hits.

Thanks for the other suggestions, though.

I have this issue as well and I noticed in on multiple movies with DV (2001 and Avengers: Infinity War). It goes away when I lower contrast from 100 to 99 as well. The lines run across the screen even when the content is paused.

Well I'm both glad and not glad I'm not the only one noticing this. There still seems to be so many unfixed issues with oleds it makes me start wondering whether true black is worth it (well we can't even have true black on our oleds anymore)

Does reducing contrast to 99 crush black levels as well?

I first noticed this issue when I watched 2001: A Space Odyssey. The movie started with an overture set to a black screen, but the screen was not completely black. I disabled Dolby Vision output from my player and the problem went away, so HDR10 does not have these issues.

I still think OLED's issues are not as bad as the shortcomings of the previous TVs I've had.

Has any one else noticed that the way the image shifter woks is by moving the image left or right a bit, thereby making the black borders slightly wider on one side or the other. If you turn it off, it re-centers.

Also, it is the case that the fireworks screensaver will come on if any of the onboard streaming apps (VUDU, Netflix, Amazon,ect) is paused?

They are still LCDs!

That's interesting. I always thought the difference between LCD and LED was that LCD tv's used CCFL as the back lighting and LED tv's used LED's as the back lighting. Apparently it's not as simple as that. AVS is always a learning experience , even for us old guys.

Heh. Yeah. You have described the difference between an old-style LCD, and an LED-backlit LCD.

The problem was Samsung calling the LED-backlit LCD "LED TVs.". They aren't!

As far as I understand it, the "rules" are, the thing that produces the light coming from the front bit is what the technology it's called!
Hence, these are all correct:
  • LCD - liquid crystals with either a CCFL or an LED backlight. The LEDs could be on the edges, or in a Full Array Local Dimming grid.
  • OLED
  • Plasma.
  • "LED TV" is a TV with the front made up of LEDs, you see these massive screens at concerts and in stadia. Get close and they look bad; perfect for what they are intended for though!
  • "Mini-LED TV" - See CES 2019 reports
  • "Micro-LED TV" - See CES 2019 reports
  • QLED - real emissive Quantum Dots producing the display; still several years away. May be swamped by Micro-LED!

These are all on a scale between misleading, wrong, and lying:
  • "LED TV" (actually meaning an LED-backlit LCD)
  • "QLED TV" (actually meaning an LED-backlit LCD with Quantum Dots, available from 2015/2016/2017 onwards in the Samsung JS/KS/qled models)

Both the above were invented by Samsung's marketeers...

Does reducing contrast to 99 crush black levels as well?

I first noticed this issue when I watched 2001: A Space Odyssey. The movie started with an overture set to a black screen, but the screen was not completely black. I disabled Dolby Vision output from my player and the problem went away, so HDR10 does not have these issues.

I still think OLED's issues are not as bad as the shortcomings of the previous TVs I've had.
Reducing contrast from 100 to 99 doesn't seem to affect the picture perceivably. However, this trick only works with Cinema mode. In other modes like Cinema Home or Game, reducing contrast to even 0 still cannot fix the elevated black, and lowering the brightness from 50 to 49 is the only solution.

Something along these lines.

Yep, this is true. However in the Samsung JS/KS/QLED use of QDs at the moment, they are only used at the back, in front of the backlight, to make its output "perfect white" and far more efficient. This enables far better colour accuracy and gamut for the Liquid Crystals at the front of the panel.

This is the best explanation I've found:


Today's Samsung (and TCL, HiSense etc) TVs which use QDs are all the Photo-enhanced (QDEF) type - he confirms it in the interview and it's still the same today


Future TVs using QDs can be Photo-Emissive (still not ready):


But what everyone really wants is Electro-Emissive, where the QDs produce the light, and the LCD is gone completely.


Each year, Nanosys is at CES and gives updates on how close they are getting to be able to do this stuff economically.

ps. A bit off-topic but this beats FAQs and lies about dimming issues
