As I've described here, v05.25.09 / v05.20.09 doesn't fix the current critical vulnerability (to my current knowledge). Which doesn't mean it might not fix other security vulnerabilities.

You are among the first to receive this update. LG is not yet rolling out the update on a large scale, which is expected to happen in the next few days. M

I have always had to download the file to storage previously if I wanted the upgrade early. Update: My C9 is now NOT offering me that update to 5.20.09. Have LG changed their minds or something? Very strange. I didn't upgrade it earlier today as I was waiting to hear more info about what it did first. Im still on 5.20.07 9

The automatic update search performed by the system and the manual update search are two different "channels". I.e. one might offer you the update, the other might not. There's nothing to worry about, you will eventually get the update (again).

Are you able to find out exactly what 05.25.09 contains/fixes/updates ?

Strange: once the notify is up the update is visible on his menu... maybe you turned off tv after that notify? Aniway I'm on last fw 5.20.09, nothing seems changed

mrtickleuk said: It's exactly as @HiFi4Vision said. The LG OLEDs with Alpha9s have 33x33x33 3DLUT slots for SDR rec.709 and SDR rec.2020, for the 5 SDR PIcture modes supported. All picture settings are stored separately. In even more detail, here is the list of the discrete Picture modes which have 3dlut slots. rec.709 SDR Cinema rec.709 SDR Game rec.709 SDR technicolor Expert (Filmmaker on later models) rec.709 SDR ISF Expert Bright rec.709 SDR ISF Expert Dark rec.2020 SDR Cinema rec.2020 SDR Game rec.2020 SDR technicolor Expert (Filmmaker on later models) rec.2020 SDR ISF Expert Bright rec.2020 SDR ISF Expert Dark Just as with switching in and out of HDR10, HLG and Dolby Vision, you can only see and use those Picture Modes and change their settings in the TV's menus when feeding the TV the correct signal. Sadly, LG doesn't give them different names in the Picture Mode menu titles in the way that it does with HDR10/HLG and Dolby Vision. Click to expand...

For various reasons I haven't taken the time to figure out ffmpeg (as mentioned by avernar) in order to set up an SDR rec. 2020 source. However earlier today I was reminded by a post elsewhere in this forum that my Oppo UDP-203 has the capability of converting HDR-10 to SDR rec. 2020 output. I had forgotten about that capability after getting an HDR capable display. Using that capability I found that my OLED65C9AUA DOES display a "BT.2020" indicator in the info banner when it detects rec. 2020 input (first image below). However the picture mode while in rec. 2020 does not appear to be isolated/independent from rec. 709. All of the user picture mode settings when playing rec. 2020 are identical to what I have set for and appear for rec. 709. In the Cinema SDR mode while rec. 2020 is active, Color Gamut, Gamma, and White Balance are grayed out indicating the installation of 1D & 3D LUTs, although I've never installed them for rec. 2020. That mode is 1D & 3D LUT calibrated for rec. 709. This at least gives the appearance that rec. 709 and rec. 2020 are served by the same LUTs. Testing in uncalibrated technicolor expert and ISF Dark modes, any change (including Color Gamut) made while in rec. 709 is carried over to rec. 2020, and any change made in rec. 2020 is carried over to rec. 709. I know this isn't conclusive, but it sure seems indicative that there is no isolation or independence within the same picture mode (name) for rec. 709 and rec. 2020. Maybe I'm missing something. All three images below were captured while rec. 2020 was active. No changes were made to the user settings displayed while in rec. 2020. OLED LIGHT 28 is my SDR rec. 709 setting for the SDR Cinema picture mode. No change was made to these settings while in SDR rec. 2020. Grayed out/inaccessible settings while in SDR rec. 2020: 9

Even if it's not what you specifically asked: there are no major changes in v05.20.09 (DVB) / v05.25.09 (ATSC) compared to v05.20.07 / v05.25.07. The biggest change has been to the LivePick service. Otherwise, you should not notice any changes. I can now at least definitely confirm that the current security vulnerability has not been fixed. 9

The input-dependent (HDMI1-4, TV broadcast, apps etc.) picture settings that can be changed by the user are not isolated in this respect. We did not refer to these settings here. What I described are uploaded LUTs which are not dependent on the input, but on the picture mode + color space in which the TV is working.

No, as described, this is not the case. I am not speculating here, I am telling you exactly how it is specified and implemented by LG. You can easily test this by uploading a LUT for a Rec.709 picture mode that e.g. intentionally displays false colors. Then play a Rec.2020 content in this mode and you will see that the colors appear correctly because the uploaded Rec.709 LUT does not apply. I hope this clears up any confusion on the subject so we can wrap this up. If not, I would suggest discussing this in the calibration related threads, where all calibrators will confirm what I have just said. 9

@HiFi4Vision is, of course, absolutely and categorically correct. When it was first reported to us that an uploaded LUT was not applying to certain inputs (namely the Comcast Infinity X1 Cable STB), it took us literally just 10 minutes to find and isolate the reason why, and implement a method to upload a Rec709 and a Rec2020 SDR LUT to the same picture mode. After testing several times to confirm repeatability on several model years of LG OLED, the method was released within an hour of discovery. This is not speculation, it is fact. But I agree with what was said above, this is quite a bit off topic for this thread, so I will leave a link to the post containing the proof below for everyone to see for themselves.

AnderC9 said: Tested: when you select HDR and then back to sdr the black level crush the tunnel test (for example), after 5/10 seconds it back normally or at least accetable". The thing is that: before 5.0. firmware the black level it's handling correctly an we can see all gradiation as far as 0.5% in sdr with just 1 or max 3 over 50 in bightness adjustment. Now with lastest firmware we do over 57 to see all gradiation, going to break the absolute black (pixel off). Click to expand...

Hmm interesting the gradient test Image I'm using doesn't return to normal, it genuinely looks like it's skipping gradations steps in near-black, this is with 4k60/120hz and 10/12bit selected.

I tested it on isf expert (low light) with uhd signal 60hz 8bit / 10bit (HDR) on ted's tunnel... no pc input.

Both are connected to my Denon AVR 6700 which in turns feeds the signal to the C9. It’s been intermittent over the last few weeks, seemingly since I updated to the latest LG sottware. I ordered new cables to see if it was a cable issue, though I haven’t received them yet. Last night was much worse, seemingly every few minutes. Tried a different input on the LG, from HDMI 2 to 1 and it didn’t do that anymore. Had it on for 30-45 minutes but need to check it again today. Can the port “go bad”? Never had an issue before. I know cables sometimes do but changing ports with the same cable didn’t duplicate the issue.

Thank you for attempting to clarify. This does however leave me unclear what you were referring to as "picture parameters" in the statement below.

HiFi4Vision said: For example, SDR picture modes have separate LUTs and picture parameters for Rec. 709 and Rec. 2020,... Click to expand...

I am not going to make assumptions about who you are and are not including in "we," but in case you didn't read them, there were also statements made in the relevant discussion (which I quoted in my previous post) regarding all picture modes being stored separately, discreet picture modes for rec. 709 and rec. 2020, and only being able to see & use specific picture modes and change their settings when feeding the TV the correct signal. I was understanding the combination of these statements to suggest that there was or should be some user observable isolation/independence in the C9's behavior between SDR rec.709 and SDR rec.2020 beyond the difference in image display resulting from the uploaded custom LUTs themselves.

HiFi4Vision said: I am not speculating here, I am telling you exactly how it is specified and implemented by LG. Click to expand...

If LG has provided publicly available documentation specifying this implementation that I have missed, then I apologize. Otherwise I consider it worthy of discussion in these forums until they do.

For anyone: There is a possibility to avoid black crush with fine tunes dark area" even in no allm settings? let me explain: the fine adjustment of the dark areas from what I have read should only affect the graduations close to black without affecting the whole screen but, in my case the option appears only when ALLM is active (and consequently it must be supported from the device sending the signal). Wouldn't it be possible to have the option on all other signals as well?

If not, why like there are downsides to this? Also: Quick update: 05.20.07 bug out my C9 standby mode. My Tv no longer put in standby mode using quickstart+ anymore and also power button on the remote. Any1 has this issue? Thanks!

1 - Quick start is a sort of cache to wake up tv at last state you leave it (example: if you press power button when netflix or other apps running, when you turn it back on you will return to the same screen in which you left it) 2 - Under 0.5W (technical sheet of 55" model, quick start consume more power to garantee a "Quick" wake up) 3 - You can put timer to turn off your tv or select min 4 hours to go in stand by if you don't touch any button or can select forced" stand by after 2 hours. 4 - I think you want to not consume any power when you don't use tv, and to do so you only have one solution: unplug power cord, BUT if you unplug the power cord or switch off any multi socket, the function to preserve the panel like the small compensation cycle can't run without current so the advice is to NOT unplug or minimize your stand by consume disabling functions like quick start+ OR unplug when the 4 hours cycle is done (you can safely disconnet power cord AFTER 5/10 min. when you hear the click of the relè) 5 - you can't turn off your tv? is this bug" you mean?

Thanks for reaching out to me! I actually want to put my TV into Standby mod all the time though but using either remote or quickstart+ still put my TV to Off instead of standby where I hear a click sound (not crack) after 1 second when the screen is off while standby = no sound effect

If you hear the "click" immediatly after turn off your tv you didn't reach 4 hours of cumulative usage so it's ok your tv is aniway in "stand by". If you turn off the tv by remote or the button under the screen you're always in "stand by". let me give you some advice: disable quick start+ and turn off tv simply with the remote without unplug power cord, you'll only lost the last task you do and you can be sure that the panel does what it has to do to maintain image quality and low power consumption. 2,561 - 2,580 of 3,072 Posts 1 129 of 154
