Calibrating the LG AU810PB projector with calman

Nope, not that i know of. Once you have calibrated, it will load in the values into Gamma Module, White Balance 2/20pt and colour tables and upload it to your LG projector, you cannot change those values except for CMS module. on the calman version i was on, i am still able to make micro adjustments in the Colour Management module on the LG. You can try using the manual colour cal post auto cal, to adjust 75% saturation and 100% luminance targets on SDR, see if that works better. I prefer to get these spot on for 75% saturation. They look very good on SDR

i dare not touch the calibration anymore, because i am also worried i have to re-do all over again all 4 profiles, very time consuming. that is why i didnt explore with the new software, because im very happy with the post cal results and after verifying with various video content, i prefer to leave it alone. im also worried one wrong button and it goes haywire and i have to reset the PJ. So im careful to make sure it doesnt go there.

If you need to test, use another profile. Expert mode seems to be best for SDR and Game mode is best for HDR… ive tried the few different profiles… i ended up with those as my main profile … and yes do not turn on Tone mapping when calibrating the PJ for HDR. That has to be turned off , its turned on by default. So becareful there.

I just build a PGenerator pattern generator out of a Raspberry Pi to calibrate my 2018 Panasonic OLED. I had previously calibrated my HU810 with the internal pattern generator, but was unable to do a pre-post comparison because, if I recall right, LG’s internal pattern generator couldn’t do it. Wonder PGenerator can do post measurements and comparisons. Will be trying in a few days time.

Hope it is able to. :slight_smile: Think sdr shld be able to.

I meant HDR. The standard Calman Home can do the pre/post in SDR, but not in HDR. I’ll take a short break after this project, but after that, will redo the LG HU810 calibration with PGenerator. There are some who argue on AVSForum that LG’s internal pattern generators aren’t bit perfect, particularly those from 2020 and older. The HU810 uses their older stuff, hence the inability to do pre/post

Just to close off this discussion, I did determine that with Pgenerator, you can do the pre/post on Calman from Home in HDR.

@Abhuj887, Replying u here as this is the more appropriate thread /post for your qn.

If u are using autocal on calman on this PJ, the calibrated picture mode’s 1DLUT and 3DLUT shld populate to the other sources including the built in apps. (LG PJ users - pls jump in to verify if I’m wrong here)

If u are using manual calibration, then it wont and u will have to hit “apply to all inputs” to make it happen.

Got it. Thanks Foodie!

The Greyscale and the CMS calibration is applied across all HDMI inputs and Netflix, USB etc, but the other parameters are unique to each input or mode. So each input or mode has unique contrast, brightness, dynamic contrast, black level etc. Setting contrast in HDMI1 will not, for example, copy over to Netflix or playing files from USB

What I learnt was (to be) always on the safer side… that is after each calibration, to disconnect the PJ, meter and close the calman program entirely, reset the mode in the PJ, then connect all and select SDR or HDR to begin calibration.

17points (it took just 3 hrs in my new computer, much faster)

The grayscale is great. But color gamut not so good
Any ways to improve it? or I did anything wrong?

Colours does look off. Are you calibrating for HDR ? If it is, it uses matrix lut for hdr, should not take 3hrs !

nope.
I am calibrating SDR BT2020

can someone please post your SDR 2020 post calibration result?

thanks

It should all fall into their respective dots post calibration like the above with delta errors <2, otherwise it’s not good enough. And it takes like 6hrs for SDR !

Yours seems like quite fast coming in at 3hrs only?

I did try calibrating for SDR2020 at the early stages for SDR content, somehow it didn’t look good post calibration

I sticked to REC709 for SDR, only HDR10 with BT20202

the above screen was just BT 709
yes I can do it with about 3hr since the computer is very fast .
I was using an old laptop that is super slow… Take 11hrs.
So I switch to a new PC and it become much quicker

I think Sammy said he did SDR BT2020?
