LG 42-inch OLED

I returned my 42 C2 in the end. The screen was amazingly good, never used anything like it. In the end, with my 60cm depth desk, it was just too big for both gaming and productivity. I have gone back to a 34" ultrawide LG IPS which is ideal for work, but I do miss the fantastic screen quality of the C2.
I Love big monitors - I still remember when I got one of the first big monitors that ever came out it ... think it was a dell 2407 oh big 24" widescreen. Cost over a grand back then. I got one of the first chinese knock off of the philips 40" monitors (wife actually uses it now for her work) - and I had been using the philips in my sig for is it 4 years now~? (really nice monitor). This 42inch c2 is actually 1 inch smaller then my philips so im actually a bit concerned its too small. But like the screen a lot so keeping it. The screen reminds me of my old catleap monitor (no or very little screen coating which in essence was a glossy screen (and probably the best glossy screen you could get ... ever.) But it has a dvi connection and it seems only old cards have those (so can run it off my old 970gtx) ...

anyways :) ... Im trying to figure out a way to run my c2 and philips on the same desk (which isnt that big).
 
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 :D

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?
i've been reading up on this more this week, and watching the "classy tech calibrations" video. While the actual method for doing a 2 point calibration manually seems straight forward enough, i have a load of open questions that it seems hard to find answers for! So much conflicting info scattered all over the place. i dont know if you've seen answers to any of this?
  1. The detailed explanations and technical detail from Ted in the links above were back from 2020, i have no idea if things have improved since with newer TV's, firmware, Calman software. they've had some pretty major updates to their colour engine since for instance

  2. some people are suggesting that the 1D LUT is fine in AutoCal, and it's the 3D LUT (Matrix LUT) that is the supposed problem, yet if you follow the 2 point manual process as per that video, that's only really adjusting the 1D LUT /colour temp part. which is apparently, the bit thats ok?!

  3. If it is the Matrix LUT that's the problem, that step doesn't apply to DV calibration, so why are some people using this method for DV instead of AutoCal?

  4. Have you seen any explanation for how a user would even establish they had a problem with AutoCal in the first place? i see comments like "it's a lottery", but whats that based on? what are the symptons? what are some decent tests to see if you have an issue? I've never experienced any noticable problems with HDR or DV AutoCal on my LG CX, or C2.

  5. Any idea why in the Classy Tech Calibrations video he sets a custom white point with coordinates of 0.3107 and 0.322 instead of selecting D65?!

Wish I had bit more Calibration knowledge to answer properly I just carried out my 1st calibration last week and even that is not so right:)

1.No improvement from what I can tell, people were commenting about this colour issue back in 2020 all to way to just 3 weeks ago, so from well known Tv calbrators to home users they quickly knew PD was not addressing it or unable to so just went the 2 point method work around fix.


2. Yes I believe you are correct, its the Matrix LUT during HDR and DV calibration that causes it but again this colour issue occurs in random movies,
its that randomness that again makes it difficult for people to perhaps report it or replicate it, that latest Blade runner movie and DiCaprios The Revenenant are good choices to trigger the fault. Not many would flick between an uncalibrated picture mode vs their calibrated mode always so perhaps this is why it was hard to detect.


3.I don't know about this one but good question, not seen any direct mention or reasoning behind it, I have seen many say they do 2point for hdr and dv, but then you see a post like this but then a bit more confusing afterwards reply which was days posted. So yeah confusing to say the least.


4.I think it was Miguels post of that scene during The Revenenant that opened a few minds up and people compared it the following few pages, while he was not posting it as a comparison he was just using it as a reference to show the colours are incorrect since he has another TV next to his calibrated TV so he spotted the colour issue right away. An example though would be The Revenant time stamp: 13.48 roughly. Also someone asked Dark007 same query but if you don't have that game he said it occurs in these type of scenes in hdr movies.


5.Another good question but sadly no answer, I thought he said in the video he would not target D.65 due to mannerisms?
Edit its not Mannerism at all lol I believe he said Metamerism, he discusses D65 and Metamerism in this video

Do you think its worth posting directly on AVS Calibration section on your own separate thread, that you are the author of the TFT Central Calibration guide and you have been made aware of problems within PDs AutoCal Process (HDR colour bug), 2 Point HDR and possibly DV work around fix, SDC possibly issues, DV issues etc, if you ask the community directly, pretty sure they will help out or at least openly discuss any issues there you could have course mention you are improving your own guide and will try to keep PD informed so improvements can be communicated and catalogued.

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 :(
Just found the final piece for this as if you did fulscreen it still stretched, you have to go to the Nvidia control panel and change the scaling option to no scaling, keep the scaling set to display, that way it's all handled by the TV.
 
So, I moved to windows 11 on a new pc. Text now looks absolutely garbage, like a slight doubling. I have windows scaling at 100% and increasing it doesn't make a difference. Cleartype doesn't make a difference. This wasn't an issue on windows 10, unless theres a setting I forgot to change. Anyone know what I can do about this?

edit: disabling hardware acceleration in chrome fixed it, funny thing is, I enabled it again to compare the difference but the problem isn't there anymore! wth... This is including edge which I didn't touch at all. Why would chrome setttings affect edge =/

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!

I managed to fix my SDR calibration with the 2nd and now 3rd attempt, you really have to double check the test pattern and 10 hour sdr videos black level is set to limited, for some reason when I did it first time it was set to auto so gave me errors with black pattern test pattern nearblack 16-27, now I just check picture settings are correct, even making sure energy savings is off and its on the right picture mode to prevent this.

Speaking of picture mode, I found filmmaker SDR does not work my end at all with 2022 series and Autocal, throws up calman errors when reaching the end someone else just confirmed to me he couldn't get filmaker mode to work either he uses isf dark/bright which is also the only modes I could get to work, and Cinema for hdr/dv. Did you have any success with SDR and filmmaker mode?

I can also confirm Autocal and HDR does not work for 2022 C2 series, tried it several times it just gives wild amount of errors and colours in the final pre/post graphs at end so I will need to do that 2 point for HDR/DV next.
 
never got round to doing the rest after doing SDR and HDR so never touched the filmmaker modes sorry.

Happy enough for the moment since I use my screen exclusively for the PC.

Good to know, yeah SDR is the main one for myself also. I also tried doing 2 calibrations one with sdc done and one without, both display the same imo showing no real benefit or difference, guess though no harm to do the extra shadow bit if you want:)

Id say 60-70% of my content is still SDR with Tv series and movies, but I am prepping on doing the 2 point balance for hdr and dv, I will be sort of using keepitclassys video and also tftcentrals hdr/dv settings and hopefully it will somehow work!

If it works ill post my own mini guide here for you.
 
2 point calibration on HDR was easy and went without a hitch following the video guide.

Yeah looks easy enough but I noticed keepitclassy is using different settings for his sessions like meter>Raw XYZ(Generic CMF) and Whitepoint>Custom,
I think TFTcentral guide is OLED TV WRGB instead and whitepoint D65, even the whitepoint targets are slightly different. Also not sure one has to do all
those other settings with DDC and source.

If you just used keepitclassy settings exactly in his video and it worked guess its ok, but I was thinking of somewhat merging tftcentrals modern hdr settings to it, guess its not too much still and just RAW XYZ to OLED WRGB and D65. Maybe @Baddass could chime in some ideas.

When you have a decent AutoCal SDR result and it took 3-4 hours the last thing you want is to redo it as you know :p

From memory i did both D65 and the custom one in the other video. Personally I couldn't see any difference much so personal choice I suppose.

HDR 2 point took way less time to do than the sdr autocal and worked everytime so didnt bother me to keep trying different things. Like you on the SDR, I spent hours so once I got a good result and nothing had gone wrong, I left it at that.

ahh good to hear, I am also trying to figure out a tool not sure you or @Baddass are aware of it its called bscpylgtv it has the option to back up your SDR & HDR calibrations and restore them but I have yet to figure out the proper command lines to do it properly, it uses that old school DOS type commands or CLI linux type commands.

If anyone figures it out should save all valuable time in future in case we mess up the TV :D

Not heard of that before but long term it probably doesn’t have much value as the panel will age and drift and you’d need to run the calibration again really. For short term accidental resets or something it could be useful though :)

Several full TV resets I am more then intrigued to learn how to back up the calibration data :cry:

I think it would be pretty cool if you could also upload different calibration sessions and compare results, sure good idea to re-calibrate properly after that drift though.
 
G3 is looking impressive with the MLA tech

but not on the C3 series and I think its not possible to put MLA tech on 42 and 48" due to size of pixels sadly.

hdtvtest recently mentioned they may have removed the TPC and GSR feature on the G3/C3 from the service menu since he saw no option on his pre model, maybe
LG ditched it finally.

Which would be a major shame for those wanting to use them for Pc use
 
Its disappointing for new G3/C3 owners for sure, it also effects just regular home TV users watching TV shows, movies that auto dimming algorithm is so hit and miss so sometimes scenes just go pitch black I guess they can't account to track dark scenes for every new tv series/movie that pops up every minute.

Lots of people over on AVF/AVS community are looking at the C2/G2 again. hdtv has released a new video since everyone moaned its a review unit not retail unit so he should not have shown tpc can't be defeated, but in vincent fashion he has corrected them and confirmed its not available on his retail 42C3 unit and G3 unit.

I watched that earlier, haven't LG now fixed the auto dimming on the c3? He demonstrates it in that video. If so you wouldn't need access to service menu anyway, I assume.

Be nice if they did that for c2 also

No you are totally right, but how does it work with TV shows or other movies other then Dune bluray disc remake, also what about the PC use.

Also I am left wondering why have LG not fixed this for auto dimming issue on C9-C2 series, the issue has been there for many years which is why people went LG since it had the option to disable tpc/gsr, VT does mention he hopes its available on other previous C/G series TVs.

I think we have to wait and see how real world varied sources perform with this new firmware or auto dimming algorithm, I would have preferred the option just to switch it off vs trusting LGs algorithm to perform correctly but if its a real improvement then its ok.
