LG 42-inch OLED

[sgavan]

Cheers. Ive gone with the video which keeps the ABL off.
Incidentally what colour temperature do you set yours to?

E: Just installed the companion app. Genius, it works!
Incidentally, I assume I have to have the software installed on every device that is connected to the panel if I want it to wake up ? (E.g. I have a laptop I use for work and connect to the panel, I take it, it also needs to have the companion app in order to power up the TV?

E2: Any idea why the text in some installation boxes appears blury?



Ive turned adjust sharpness down to 0.

E3: just one more question please I tried the UW mode but for some reason when I run some games at 120hz at UW 3840 x 1600 the screen stretches. Any ideas?

Hi not sure if resolved but I noticed in the new update it tells you the resolution the game needs to run at, any higher and it goes full screen 16:9 3840x2160, 21:9 3840x1600 and 32:9 3840x1080. You can run a game fullscreen at these resolutions. I use the 21:9 for racing and flying but not strategy games. It would be great to be able to have a hot key to change this or customise the game optimise menu to haveit there, you can edit it but not put all options there just what LG provide

Actually @Greebo found a better 2 point white home video, was done on the LG C1 though and he also did it for DV and HDR through manual calibration mode on Calmanhome. I think it looks simpler and quicker to do also, which at this point is most welcome lol

I believe @ViRuS2k was looking for a video perhaps doing similar.

Starts at 30 minutes into video but its well worth watching whole thing to get an idea.

Thanks.Going to attempt it this evening.

My C2 arrived this morning and games looking great on it although havent done much in the way of set up yet apart from setting it up for 4k 120Hz and PC input - will take a bit of getting used to the size!

Windows HDR calibration tool and the advice/videos/links in this thread. I can't imagine a better way to game now.

@Baddass, not sure if I mentioned this a while back but was just reading through the TFT central calibration guide, end of SDR section while doing the extra shadow level detail bit. Someone on AVS community is advising not to follow that part saying its inaccurate, did they do something that maybe updated it and you have yet to update the guide?

I don't agree with some of the advice in that post, and in fact it's contrary to advice and guidance very knowledgeable people at Portrait Displays gave me. I'm not sure why he's decided to just label my guide as "wrong", it doesn't seem to be based on anything other than the below differences, but actually I believe he is wrong on these areas. My understanding (based on long conversations with Portrait which I'm pretty sure he won't have ever had) is different to his, but i will contact them again to double check the advice.

1. He's suggesting to do the shadow detail correction (SDC) after 1D LUT (greyscale) but before the 3D LUT (colour and gamut). This is ok if you want to, but having quizzed Tyler Pruitt at length on it before, his recommendation was that it would be optimal to do it after both steps - as per my guide. Tyler worked at Portrait for many years and is super technical and knowledgeable on this stuff, but he's unfortunately now left and moved to a new company. He used to post quite regularly on AVSforum too, you will see him on there in some of the older discussions.
   
   
2. He's suggesting that before you observe the SDC patterns you should untick "enable calibration" because, as he puts it, "if this setting is ticked, the Gamut will not be in the correct state to view the pattern."...if true, this is probably another reason to do the SDC AFTER the 3D LUT stage as well I could see that perhaps having some small impact if you were calibrating to SDR gamut (sRGB) from the panel's native as you'd want the gamut to have been corrected first (so do the 3D LUT step first!!), but I doubt it really makes any real difference either way as you're only observing very dark greyscale detail here. The main problem with this is that if you untick that "enable calibration" here, it will end your session. Ticking it again later to upload the SDC, and then unticking, re-ticking etc as he describes will mess up the 1D LUT calibration. Tyler specifically told me that it was very important to NOT untick that until you'd finished everything. It will mess things up, so i would strongly recommend leaving that ticked, doing the SDC and only once you've finished everything should you untick it to end your calibration session. I will check with Portrait again on this to be sure, but that's what Tyler told me.

Thanks, its certainly a confusing one I actually also asked about the SDC in general and another popular calibrator member who is both on AVS/AVF communities told me its nothing special and just an re-upload of your custom 1DLUT.

I think I need to start taking up drinking

it's not vital, but it can make some minor differences. It was designed to help handling of near black detail on OLED panels primarily, but we're talking very small variations in the darkest grey shades, that you're probably not going to see unless you're viewing very dark content, in a very dark room (i.e. reference OLED viewing conditions). I'd think of it as more of a nice-to-have, but if you didn't want to bother, or forgot to do it, it wouldn't be the end of the world

@Greebo any joy with HDR and DV with manual 2 white point method?

I figured out how to search within single threads on AVS and can see lots of post on why many switched to doing it manually 2 white point method. Technical explanation here and here, its an issue I believe for LG 2022 TVs this is why there might be some confusement.

hdr 2 point worked a treat. not had chance to do the DV yet.

Awesome and hopefully it was quicker and with accurate colours at least!

 

[Baddass]

Some of the posts you guys have linked to for the 2 point calibration and the problems people were reporting are from May 2021. Without reading endless threads on AVS, are you sure these are still the same problems?

Portrait have told me there are still issues with 2022 displays and the IPG, which LG are very close to fixing apparently via a new FW so it could be simply down to that.AVS isn’t the easiest to follow and navigate!

I have been slowly reading the last 200-300 pages of that mega thread past few months, I think that HDR/DV colour issue might have started around 2020 actually not just just 2022 LG TVs with LG Calman, so that is why someone referred to autocal in hdr as a lottery. It was Miguels post 2 weeks ago that openly said in plain english Autocal HDR is a waste of time I understood that english part

This is dark-007s post last week and again his April 2021 post, you can see even under that last post Wifi-spy/Tyler was still around posting but I don't think he addressed this bug or colour inaccuracy issue but even below that people are playing games and films and spotting the colour issue.

Even Connecteddd has mentioned his own software has issues with HDR calibration so was mentioning manual or 2 point method. And I believe people still had the same issue when using external patterns via that Rasperberry set up so went 2 point/manual way.

d-mans post to Miguels who done a 2 point calibration also here confirming his 2 point is correct to his own calibrated TVs at home, also Keepitclassytech who shows he does the 2 point in his C1 calibration video, if you read the YT comments 1st post by Dario P and the 5 other replies even Ninjacian TV calibrator also does the 2 point.

I think its a blink and miss it thing like Miguel mentioned in his post so perhaps most people that ran autocal for HDR/DV do not see the incorrect colour issue unless they compare it to another uncalibrated picture mode or correctly calibrated TV or just OOTB TV. But surely 3-4 calibrators and the biggest community are right here. It does not sound like LG and Calman can fix it also since its been this long of an issue, but maybe you might be able ask PD about it?

Would there be any reason for my computer to start to 'hang' since upgraded to this monitor and using hdr in windows? - cant quite figure out what my issue is and havnt done much else with my computer. Windows and AMDgpu drivers up to date.

 

[Greebo]

Awesome and hopefully it was quicker and with accurate colours at least!

Super quick and easy and the test afterwards showed less than 0.5 delta in the colours so leaving it at that. I'll do DV at some point as well.

Went back to redo the sdr properly again as I wanted to do the dark details extra option this time round. had a nightmare. The autocal kept throwing up stupid results all over the shop. Took me about 5 goes before I got sensible figures again. So wont be doing sdr autocal in a hurry again!

Good to know HDR gets good results,

I tried my first calibration, but I must have been doing something with the shadow dark details part wrong while following tft central guide, using the OLED shadow detail slider and pressing commit on/off button there was no changes on screen at all to my medialight shadow detail video test and I tried moving the slider back and forth to random points several times and also playing the video and pausing it.

But since 64 was black and 65/66 black also and rest of boxes as per the guide details I just left it and finished off the SDR calibration.

Since you at least got some results that must mean I did something wrong setting wise, but since its my 1st attempt ill re-try this.

Were you pressing “commit” after each change to upload the new setting? And did you check you still had “enable calibration “ ticked in that same menu?

 

[Greebo]

I must admit I had the same issue as R3X. Clicked commit every time and had enable calibration still ticked but moving the slider changed nothing that i could see. I even moved it almost all the way over to the right and I had the same pattern on my screen to put it back at 320 or whatever it was set on and left it there.

Yup had enable calibration enabled/ticked always, I tried moving the slider to random points and clicking commit to see if anything changed on screen, must have tried about 7-8 different points with commit button each time but no difference at all. I noticed on the guide it does not mention to set black level/video range to Limited or Full or Auto, I left mine on Auto on the C2 while on PC source (4K, RGB full, 8bit) do you reckon I should have put it to Limited on the C2 that way its matching Calman. Maybe this could be the reason I saw no difference but unsure.

Oh so you had same issue as myself, glad I am not alone did you notice the blocks are actually fine with 64 being solid and 65/66 black also?

This is why I just finalised the sdr calibration since everything appeared spot on to the guide anyhow, it was as if the calibration did all the hard work earlier or as best if could either that or I made a mistake with not setting the C2 Video range/black level to limited before calibration.

I just wanted to report back about this monitor having owned it for a few months.

Short version: The best monitor I've owned.
Long version: After putting the settings as per the advice in some of the videos which have been linked to by some kind OCUK folks, I do not witness any more autodimming, the brightness is spot on and playback in games, video, desktop is just outstanding.
The real estate is phenomenal, I was worried I wasnt going to get on with it, but to be honest when I go to the office and use my twin 24" screens, the difference is day and night.
