Are you playing a HDR file off a USB stick when using the internal TPG? When I used that, nothing was plugged in. If using an external TPG, yes, plug in directly otherwise pattern may not be perfect.
Never hung during calibration for me, but I plugged Ethernet directly. Didn’t use Wi-Fi
So where was the HDR file stick being plugged into. What device as source you guys normally use
Oh yes, I must mention the unit that got hung was using wifi. U r right. I never experienced that at home , in my case, even running 17 point grid was perfect, no issues
5 hours plus just for the 3D LUT grid 17, crazy long. But colours look so natural post calibration. The aurora engine’s improvement I’m seeing now is with skin tones. The skin tones look so natural !
Yes the patterns were loaded through Oppo 205 and connected through the PJ input hdmi , no issues they were all on the same network. Calman is able to communicate with the projector to trigger the Oppo to playback “XYZ” pattern
Don’t need to use any external pattern generator when calibrating the LG
Skin tones look very natural, very nice with this aurora engine…
Damn ! Should have done it last year ! Better late than never
So big improvement with the 2022 update for projector owners
Oh yes, and I must mention my laptop is still on windows 10. I dare not upgrade to windows 11, later this not working that not working 
… so far on windows 10 all seems to be working , including rew etc etc
The skin tones really very nice, well worth the time recalibrating with the aurora engine feature . Very nice indeed
I think I see the benefits of calman over chromapure. I can never achieve this type of quality with the chromapure…there is quite a big difference between the two
So for this calibration, we’re you using the Feb 2022 Calman or the latest version?
The Projector’s USB port. When you do this, nothing needs to be plugged into any HDMI port as the LG’s internal pattern generator is being controlled directly by Calman over the network. The files for the usb stick were downloaded from Portrait.
Later I recalibrated with an external pattern generator. One key advantage of this is you can generate a pre/post calibration, which you can’t with the internal pattern generator. Also, according to some AVS folk, the LG pattern generator is not bit perfect so you get a better calibration with an external pattern generator. As I’ve done it both ways, I think LG’s internal PG is good enough.
Feb 2022 version. I didn’t go with the newer versions 2023…. There is no improvement made for projector but OLED owners… sometimes when they fix one issue they brick another in the process… so since this Feb 2022 edition was updated specifically for projectors owners, i keep to this version… best … so far I’m seeing a lot of improvements over the 2021 version…
Didn’t compare the 2023 version
We must use the source that’s connected to that hdmi, not the usb port on the LG projector. That one has a different picture profile by itself
Did u use the Pj usb port when calibrating ? If you did that, it’s only calibrating for the profile of the built in application, ie playback of media & video through the Lg usb ports or playback of Disney +, Netflix through the native built in app on the pj.
If u r connecting an external player like Oppo, zidoo or Xbox, u need to calibrate through these devices hooked up
U must plug the pattern generator into the Oppo 205. Choose the correct picture mode and hit reset, then u need to set brightness and contrast using test patterns before u start calibration.
Also u need to change black levels to high and disable all processing and set energy savings to medium or max depending on your room ambient light. U can change this later post calibration. Then set iris to the correct number( this one very important as it changes colour temperature)
Your Oppo is part of the video chain, so u want to calibrate your display with the Oppo in the chain…
Sure, you can use a HDMI port to put the projector into SDR or HDR, but that’s all it does - put the PJ into the appropriate mode. When I was calibrating initially with the internal TPG, I found it convenient to run the USB stick to put the LG into HDR or SDR. LG’s internal TPG is like a RGB overlay (similar to the on screen display) so it doesn’t matter which input the signal is coming from. What’s important is that the display switch to that mode so the RGB internal TPG can be run as an overlay over that mode - SDR or HDR.
When you run Autocal on Calman, 1D and 3D LUTs are uploaded internally, bypassing the factory LUTs for that specific picture mode e.g. Cinema. These newly created LUTs apply to that one specific picture mode across all inputs automatically. So it doesn’t matter if you use the USB input. After Autocal, there is only one 3D LUT for all inputs including all the HDMI inputs. However, each input has separate specific picture processing, such as dynamic contrast, iris etc. So they will look different unless you make all the picture processing settings the same.
I initially thought each input had a separate 3D LUT because I was coming from BenQ, where you could have a different calibration for each input. I was corrected by @Foodie who has been autocalibrating his LG OLED with Calman for some time. I checked and he was right. When I did an Autocal, it was applied across all inputs. If you observe any differences, its not from a different calibration, but from different picture processing settings that are still unique to each input.
That is not the case. I’m observing it to be different. Based on what I’m seeing, the inputs are not the same. It “Does not” automatically upload the LUT to all the inputs. That is not true.
The above is the calibrated expert dark on input 2. It is using power gamma 2.4 calibrated with iris 0
Above is previously calibrated expert dark with gamma BT1886 using hdmi 3. They are greyed out and u cannot change this . It has been locked down for that input. Observe this one has the greenish tone to it because it was calibrated with iris 8.
So it is not correct that u calibrate through the usb port on the Pj and it automatically applies to all input. This is not correct
Even if u try and apply it to all inputs, it doesn’t, because it is locked down for that particular input only .
Are you sure @Foodie is doing something similar ? Or is this possible now with thr newer oleds ? That’s why he mentioned it.
As far as my test goes, this is an incorrect method for calibrating the Lg projector
Remember you have to set the exact same picture processing on each input. Hence, if you are locked out and can’t set the picture processing settings e.g., Gamma are different for whatever reason, then you will not get the exact same picture. But the 3D LUTs uploaded by Calman are the same for each input when you do an Autocal.
I am actually very sure about this, not just from my observation, because I also had the same discussion on the LG projector with ConnecTEDDD and Liberator72 (now 9404744) on AVSForum and they were the two who confirmed to me how LG worked exactly as I was having an issue with PGenerator. ConnecTEDDD is the creator of Lightspace and is extremely familiar with these things, as is Liberator72, one of the key PGenerator people.
Anyway, no worries, when I visit your place, I believe I will be able to show you.
Currently my LG is mostly calibrated using an external TPG via a HDMI port. However, I left a mode - Expert Dark - calibrated using the USB port and internal LG TPG.
Yes it is exactly the same picture mode, expert dark. U can even observe one has more greenish tint to it… that was the old calibrated iris 8 version on input 3, the same expert dark on input 2, is calibrated with iris 0 recently. Nothing is updated automatically. The input 3 is still with old calibrated profile. And u can see one has gamma 2.4 another BT1886. I’m very sure they are not uploaded simultaneously to all the inputs , 100% sure about it …
What I know is when the readings from the meter takes place, it is updated to the Look up table live basis. So let’s say u have calibrated to 3000 points and the electricity tripped, when u turn on your Pj again, it will contain the info up to the 3000th reading loaded into the projector. But this update, only takes place in that particular single input 2, not across the entire input 1,3 or 4
It’s following a pattern whereby it reads, upload setting, read again upload settings …
You might wanna check again, see if the input is showing correctly for gamma across different inputs…
I know this because Input 3 is used for daylight watching with BT1886, and input 2 I use it for night mode with gamma 2.4
Bryan, are certain both of your shots are in the same mode i.e., SDR or HDR?
For me, HDMI1, HDMI2 and HDMI3 are exactly the same. Both Color Gamut and Gamma are greyed out. From what I recall, I only calibrated with the USB file running for Expert Dark and Gamma on all inputs were greyed out after I did the calibration. Using the USB file were Tyler Pruitt’s instructions. He even provided a link to download it. It seems that some modes lock Gamma and some don’t. My only possible explanation as to why you are still able to adjust Gamma on one of the inputs is that you have an early firmware. Mine is .37 and I’m using a newer version of Calman.
Yes absolutely sure, also calibrated another LG projector last week, same.
The reason I know is because I’m using gamma 2.4 on input hdmi 2 and BT1886 for input 3. Very sure the autocal update only does it for that specific input only, not across all the hdmi or usb ports . Even after calibration u apply settings to all input, it will not be updated. It is locked down for that hdmi input only , which is kind of silly from LG. It should apply to all inputs to make life easy for the calibrator
Tyler’s instructions were for OLED TVs , he was still playing around with the projector at the time . I suspect it could be the case for OLED TVs where all are updated, not sure . Don’t have an OLED calman capable tv to confirm . Like u have mentioned foodie confirmed it. So it could be the case with OLED TVs . But for Projectors, confirmed not the case
Since Gamma for inputs I never calibrated are greyed out in Expert Dark SDR, it’s not the case for my particular LG HU810. Perhaps it’s different for AU810s? Or the firmware, or the version of Calman. I also recall, when you reset DCC in Calman, it restored all inputs to the factory LUT
Yea, when DDC reset is done, it will clear the LUTs on the pj for that particular input only, it doesn’t clear for all the inputs simultaneously
Does it clear everything on yours ? Meaning u hit ddc reset and it clears the LUT for hdmi 1,2,3 simultaneously?
Mine doesn’t do that
It clears all inputs on mine. Perhaps the HU810 has only one LUT memory, whereas the AU810 has 3? But it resets only that picture mode. Not all of them
