Hi,
This is my 1st posting since joined 2007. lol. One thing I am interested in is applying madVR 3d lut to LG OLED in PC HDR mode and wonder if it's ok if I create 3DLUT SDR DCI-P3 via displaycal or Calman and apply it to madVR for HDR? (I have Calman and K10 meter btw.) I've tested SDR DCI-P3 3D LUT in 4K projector via madVR pixel shader and it worked well. But LG OLED SDR mode does not boost up to 700 nits giving only max 400 nits so HDR-to-SDR via pixel shader does not give higher impact. What solution do you advise to get a calibrated HDR in PC? no 3d lut solution for madVR HDR and just HDR calibration via Calman? Thank you Last edited by freebits; 18th July 2021 at 09:27. |

We had problems with 2018 LG TVs, that's why we tried/use synthetic 3dlut with hdr output. But if you don't have any issues with the factory 3dlut processing of your TV then just leave it as it is, or can calibrate the TV with calman.

I'm fine with HDR 3d lut for my 4k players via Calman matrix lut but for GPU & madVR, I don't know how to create 3D LUT for PC HDR mode. I can do SDR BT2020 lut via madVR's HDR-to SDR conversion but it won't work effectively for LG OLED TV since SDR mode is not brighter than HDR, right? neither HDR BT2020/P3 lut is possible since measuring madVR's HDR is unstable, no? Is it successful for you when you do HDR 3D LUT via madtpg? |

Well nVidia RMA'd my 2070. We'll see how that goes. I've not been able to secure a 30xx card so hopefully I can at least get myself back to where I was and get testing again.

In short, I didn't like the result, so just ended up using synthetic 3dlut: you can read from here (2 pages) So, if you are satisfied with 3dlut of the TV then no need to create one for madvr, unless you want to experiment with it. And that's how I watch SDR

Hey chros, I haven't been on this thread for a long time, but I was one of the people complaining about really bad cyan/purple color bands in HDR last year.
I skimmed through the new pages in the thread and it seems like you might have found a fix for this problem (yay!). But there were over 50 new pages of comments so it's a lot to go through. Is there any specific comment that has the instructions for implementing your fix? Would love to be able to watch my local HDR content again. |

Just read my quoted post above yours, the link is there and follow the 2 pages discussion. Which TV do you have?

Yeah, only PC mode displays 4.4.4 (check here and download the image and open in paint3d to test - https://forum.doom9.org/showpost.php...ostcount=25082 )

Does this matter for video playback? Isn't all video content available encoded at 4:2:0? Is gaming your worry or is madVR affected somehow?

I don't game, my rig is mainly a HTPC. Does it matter for video playback via MadVR? - that's down to the eye of the beholder I guess, but MadVR does an upscale and conversion from 4.2.0 to 4.4.4.
For me, I notice a difference, even at normal viewing distance - even did a blind test with the wife, and she picked up on it. But, YMMV.

TV shows and Movies, but like I said, let YOUR eyes be the judge.

I'm much more sensitive to movement imperfections.

LOL... we all have our own deal breakers... I personally don't like the jitter of OLED and as such I use TruMotion with a 2/0 setting. Another for me is banding in HDR, so I do NOT use PC mode. I hate not having 4:4:4, but the other two are literally deal breakers for me.

these screen should be burned for the terrible coating.
even the much better CR on these display levees me cold compared to a static 5 K CR display is it better no question but whatever. the test ufo is just an work of art on these displays while it is not the sharpest it has zero over drive or other issues it's absolutely clean i may even say better than CRT. the screen uniformity is is also unmatched. |

OLED tests
Anyone with newer models (2020/2021) feel free to test these (can be done in 1 hour), thanks.
A. Prereq: - for near black testing scenarios use pitch black room and let the display warm up for at least 10-20 minutes beforehand - presets on TV: use Filmmaker/HDR10 Cinema (not home) for HDR10, and Cinema (not home) for DoVi - - reset the used preset, disable all unnecessary processing, leave brightness/contrast/oled light at their preset defaults, set D65 color temp (if it's not set) and adjust black level to your settings (low/high) - for HDR10 use PC mode (chroma 4:4:4) - - during testing pause playback, and switch between normal and PC mode to see differences - PC output for HDR10: RGB Full 10/12bit output in nvidia panel + madvr set to 10bit or higher (@24/25/120Hz) - - use passthrough in madvr for HDR10 - with DoVi test: you can switch between TV-led or player-led of you have an Oppo (needs a restart, more info) - - you can also use Plex app and plex server on PC to play DoVi files back on the TV, or via USB, or any capable external devices (but all of these can behave differently!) - - I don't have chroma 4:4:4 with DoVi with my B8, not even in player-led via Oppo, but it triggers the usual PC-mode issues here! B. HDR10 in PC mode (chroma 4:4:4) 1. what about banding in HDR10 PC mode? test it with Mehanik's HDR10 test patterns ("03. Grayscale\02. Ramps\01. Diagonal Ramp 400nit.mp4") 2. near black posterization in PC mode? (last part of this post for sample and description) 3. black clipping in PC mode? (use "01. Black level\01. black-level-v1.mp4" from Mehanik's HDR10 test patterns) 4. bt2020 color processing issues? (more info, you need Netflix for this test to be able compare it.) C. DoVi 1. does DoVi have raised black and still crush near black at the same time? use Stacy's profile8 single track version (original profile7 dual track version), (or alternatively DoVi samples from here), more info - look for elevated black level (there's no true black on 2018 models with DoVi!) - look for "glowing" black: if that's the case then the underlying 1dlut is responsible for this D. A possible answer: - B1: "Not much difference between normal and PC mode, PC mode shows a bit more banding" - B2: "I haven't noticed much issues, except for @03:25 part that has posterization in PC mode" - B3: "all blinking above 64 in PC mode" - B4: "I don't have Netflix" or "I don't see any difference" or "hdr10 looks green/way worse" - C1: "Using USB + internal player: there's no true black (the whole thing is elevated) with this pattern, >=72 are blinking, plus there's "glowing" in the middle of the screen"

That's correct, I copied it from an older post, sorry Yes, I/we have 2018 models, that's what I compared to. (Just edited the post.)
