LG 42-inch OLED

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.
Nice no auto dimming? - did you have to err get the special remote to get that to work, also are you worried that youll burn in a picture without having auto dimming? - also what settings or video was most helpful in this regards - I know theres the tftcentral video anything else you recommend?
 
I bought the remote and turned it off as explained in the videos.. I have the pixel shift function on and taken all the precautions.
There was a post with several videos... let me dig out.

E: Let me make a disclaimer that whilst I like this monitor I know there are a lot of monitor experts here who go the full length to calibrate their monitors to get the settings just right, Im a novice compared to them so please bear this in mind :)

Thanks for that - I feel like I could get this monitor looking and functioning better.
 
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.

That's odd. In situations like that it might be the software gotten confused and is not uploading the adjustment properly. It's only very minor changes usually, and so i wouldn't be too worried if i hadn't done it at all tbh, it's not the kind of thing you're likely to see much difference with, if any, in real use. But for situations like that i would probably recommend trying:
  1. Un-tick "enable calibration" from the DDC menu, then re-tick it and try the shadow detail correction (SDC) again. See if that re-connects it and makes the visual changes when you move the slider. If that fails...
  2. Disconnect the display from the Display connect tab at the top, then re-connect it. You would then need to make sure "enable calibration" is ticked in the DDC menu again, then try SDC steps. 0
Having experimented with it this morning (in SDR mode at least so far), doing this will not mess up the 1D or 3D LUT calibrations, as long as you remain within the same workflow. If you were to close the software, or close the session and go back in to it, ticking "enable calibration" later would reset your 1D LUT so that would mess up what you've done so far.

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.

Leave it on "auto" on the TV. in Windows and your graphics card settings you should be set to 0 - 255 full RB range as normal. In the Calman software you need to leave that set at "video (16 - 235)" in the gear icon in the top right (workflow basic options section > luminance levels), which should be set automatically from your workflow anyway as you follow through the steps. You shouldn't need to change anything else. i expect if the SDC slider is not having an impact when you press "commit", it's because the session has gotten confused and somehow disconnected. But try my suggestions above if it happens again. i've found sometimes Calman can produce some odd results, that never seem to be fixed no matter how many times you run the stage. usually an exit and system reboot fixes it though, and it works fine again after a PC reboot.

So long as you dont want a super bright desktop screen (who does?) this works a treat
 
Actually another possible reason why SDC was not making any visual changes for you which I came across earlier today…you need to double check that the mode you are calibrating is active when you go to the usb stick and view the shadow details patterns! It might not necessarily be on the same mode via the menu that you’re changing! Caught me out earlier :)

That sounds like it could be it! so does that mean if I selected say filmmaker picture mode to calibrate during calman then when I play that medialight shadow video I have to make sure its on filmmaker picture mode also?

I will try this and the other suggestions, thanks.

Absolutely. But when you go to view the shadow detail test patterns it won’t necessarily be in the same mode you were calibrating. Very likely to be the issue. I’ll add that note to the guide :)

Wow! Doh! I reckon that could be it!!!! Why didnt i think of that at the time?

watched the video he suggests not to use hdr in windows? - didnt catch why thats the case? - If using my computer for web/movies/games wouldnt it be better to set hdr in windows? or? ...

Meant not use HDR for general day to day usage. It messes things up. I only switch it on when i am about to game or watch hdr content. Normal desktop in sdr

"Windows key + alt + B" toggles HDR on/off in windows. Best tip ever IMO as finding it buried in the settings each time soon becomes annoying!

for those interested, i had various convos with Portrait Displays and did loads of testing and experimentation this week on the Shadow Detail Correction stage of LG AutoCal, in particular trying to answer two discrepencies between my guide, and some advice on AVS forum. you can read my findings and feedback here (posts 16, 17)

Glad you are posting down there, I should have posted earlier there were other TV calibrators and users over on AVS community that mentioned the SDC wasn't all that important, certainly did feel not many down there even bothered with SDC really but sure Tedd has replied to your post, he is very good with TV calibration and informative, I believe helped develop the Raspberry Pi test patterns, has his own Colourspace calibration software he's a top dog respected member over there.

Still left wondering since I think he is suggesting to avoid SDC in his last reply?

Also D-man replied to my query about black level/Video Range either Auto or Limited/Low before calibration he suggested if you trust AutoCal and LG software leave it on Auto if not cover your backside and set to Limited/Low, I guess that is one way to reply :D, no choice given Calmans track record, Low/Limited I might have to try next, but I think I may skip the SDC part all together if you feel it best... I guess I can always re-run it again and compare any differences also.
 
Personally I use SDC still. I’m happy with the results and my panel has some crush near black otherwise. I know Tedd doesn’t rate it, but Tyler always did and he also certainly knows his stuff. At the end of the day it’s prob minor minor differences in real content and use anyway :)
 
Ps you’d soon know if the range was off, I’m sure it would throw up weird results and an odd image. I’ve never had a problem with that aspect of it myself on any calibration

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 can't be sure but I think the SDC or perhaps something else does cause me some weird results, I have an existing black test pattern and it throws up a strange error like incorrect blacks/missing sections on it. So having just read Mr Tickles recent reply, I think my issues might be what he is discussing with Raising the black floor or potential picture oddities.

When I had my TV calibrated 6 months ago by a professional TV calibrator it too threw up the same exact error no less with the same black test pattern so I think he might have tried that SDC part also.

If you can its this test here called Near Black 16-27, if you stick it on a usb flash and connect to LG TV and run it off the inbuilt media in a dark room you should see it look like this ie all the boxes on display apart from the row or white line of black boxes:

raised-image-so-should-look-similar.jpg


This is how mine sorta looks currently with that Nearblack 16-27 test pattern, that's with a tv factory reset+TFT central SDR calibration only section done:
DSC-0114.jpg


Actually if @Greebo if you wouldn't mind running the test, might help solve this riddle.


Editing this post, you have to make sure after you turn on and enable test patterns and even the 10hr SDR video, that black level is on "Limited" not Auto, also good time to double check its set to right picture mode and all other settings are spot on otherwise you get errors like I did above.

Been saying it for a while it really is a big beast for a daily desktop user, I struggle with an 80cm and still 50cm back. I believe LGs newer smaller OLED monitors the 27 and 31" are not 4K though but might be decent options in the future.
