MadVR in use with LG OLED Thread

[huhn]

Then you don't have to do anything special, just setup a profile in madvr with "if (HDR) ... else ..." and set the 2 3dluts. (madvr requires gamma 2.2 3dluts for hdr2sdr tonemapping).
But you don't want to do this on an HDR capable display, but output HDR all the time, but you will see. :)

3D LUT calibration isn't good enough for me it has to be also calibrated outside of madVR.

for gamut this CX can change the gamut in PC mode but if VRR is triggered it will force auto and i have not yet confirmed if it is wide in this case because the colors are really really off on this device.

if i used 60 HZ 1080 to see how good the scaler is the screen just started to flicker like crazy i'm happy to be not affected by this but i can hardly look at the screen.

PC mode is utterly confusing me with it i can change the gamut setting outside of game preset which is by other TVs needed for "PC mode" but for this TV it doesn't seem to affect input lag and it also doesn't affect 4:4:4 so why is gamut than limited in preset game?

isf expert dark mode is less accurate than game with warm 2.

i'm utterly confused by this device but everything except the 60 flicker issue should be fixable if i take the time the CMS if not buggy seems very powerful.

my first HDR test was very disappointing there is barely any difference between SDR brightness and HDR brightness (with default settings).

the brightness option seem to be the biggest mis engineering i have seen in a while it just rises the black floor extremly on an oled did i get this correctly? what is the point of this...

on the sony TV i couldn't even find a combination of setting where the screen would start clipping black/white levels and the CR will not suffer to much from the settings too this includes brightness 100 and CR at 100.

[huhn]

10 bit RGB and 8 bit RGB are the same in term of banding is bad but shouldn't be to big of an problem.

btw. i'm starting to loose it:

what the hell are you doing?

[oldpainlesskodi]

On my LG Oled, I found that the "Smooth Gradation" option on the set actually caused banding lol (full chain)..so now it's off!

[huhn]

clearly possibile but for testing it needs to be off anyway.

i just found the energy saving thingy turning that off would have given me a much better first impression.

100 nits HDR wasn't impressive at all.

what is the highest none ABL 50% white this TV can do? 260 nits?
the ABL is horrendous as expected. utterly hate stuff like even on FALD i turn the active back light off because it's just bad and this is very similar just in bright scene.

[chros]

the "Smooth Gradation" option on the set actually caused banding lol (full chain)..so now it's off!
Niiice, never used it, it's switched off here since the beginning. As a matter of fact, almost everything is switched off :)

3D LUT calibration isn't good enough for me it has to be also calibrated outside of madVR.
I see, then for SDR you can use different presets of the TV (Cinema, Filmaker, ISF Bright/Dark), so you don't need the bt2020 flag either.

PC mode is utterly confusing me with it i can change the gamut setting outside of game preset which is by other TVs needed for "PC mode" but for this TV it doesn't seem to affect input lag and it also doesn't affect 4:4:4 so why is gamut than limited in preset game?
Good question, LG always did that.

isf expert dark mode is less accurate than game with warm 2.
That's weird, ISF presets should be the most accurate ones (in normal mode anyway).

the CMS if not buggy seems very powerful.
I wouldn't bother with that for SDR: leave factory 1dlut in place, then create a 3dlut and upload it into different presets.

my first HDR test was very disappointing there is barely any difference between SDR brightness and HDR brightness (with default settings).
LG on older sets defaults Oled light to 80 in SDR which is waaay too high. I use 33 (~120 nits) with gamma 2.4 for night, and 39 (~140 nits) with gamma 2.2 for day if it's necessary. (SDR 3dluts on top of these in madvr.)

the brightness option seem to be the biggest mis engineering i have seen in a while it just rises the black floor extremly on an oled did i get this correctly?
brightness yes, use only oled light, leave brightness/contrast on the preset default (that's their bypass settings).

https://abload.de/img/lgemj8b.png what the hell are you doing?
:D For whatever reason Windows reinit your display all the time (hence madvr sees it as new device).

i just found the energy saving thingy turning that off would have given me a much better first impression. 100 nits HDR wasn't impressive at all.
:D Turn off every bullshit setting, at least for madvr in PC mode.

what is the highest none ABL 50% white this TV can do? 260 nits?
rtings measured (https://www.rtings.com/tv/reviews/lg/cx-oled) more in SDR.
You have to specify the mode you use (and LG can even vary between presets in a given mode! Cinema vs Filmmaker)

the ABL is horrendous as expected.
You can turn off ASBL and GSR in In-Start service menu, these are the ABLs (https://www.avforums.com/threads/lg-oled-c8-owners-and-discussion.2162797/post-28296896) that we know about.

[chros]

Guess I have to mess with this too.
I have set up the Saturation (-is) gamma 1.0 3dlut as default, images are stunning, after 2 years watching that crap finally we can enjoy HDR10 again!
Unfortunately this sometimes results in oversaturated skin colors, while fire/explosion are still desaturated.

Then I just turned on madvr's saturation feature at +8, and I tried Absolute again: unfortunately it pushes blue too much in dark scenes, so I don't like this either.
But with this (+8) and "Preserve saturation" (-ims) looks promising after couple of clips, I'll use this as default and if I won't notice anything outstanding then I'll never touch this crap again! :)

[j82k]

Too much saturation in blueish dark scenes is normal for the C8 I think, as I also notice this in SDR and also noticed this when I had the C1 and C8 side by side.
I call it the Blue Plague. :D Still better than the mix of cyan/magenta we had before though...

Perceptual has less saturation in these scenes but it shifts blue too much towards purple.

I found absolute colorimeric HDR to look quite similar when comparing it to HDRtoSDR.

As for gamma, I don't really know. There are minor differences but I couldn't tell which looks more correct.

[biship]

For the C9 & passthrough, is it best to set 2 calibration profiles, one for HDR & one for SDR and set them as already calibrated and BT.2020 & BT.709 respectively?
Or when using passthrough, is there even any need to set any calibration option and just disable calibration controls for this display?
What about disable GPU gamma ramps, which isn't available when disabling calibration?

[chros]

@biship: for passthrough it doesn't matter what you set, nothing will be used.

Too much saturation in blueish dark scenes is normal for the C8 I think, as I also notice this in SDR and also noticed this when I had the C1 and C8 side by side. I call it the Blue Plague. :D
Did the C1 also have this?

I'm not sure about sdr here (since I use 3dlut for madvr), DoVi is fine, but HDR10 factory 3dlut is pushing way too much blue. The amount of blue it has is almost like with the "Absolute" 3dluts +8 saturation in madvr! That means by default LG added saturation to the hdr10 3dlut to make it look way punchier.
Take a look at this sample 04-2160p_23fps_hdr0999-l_s02e01_cyan_error.mkv (https://mega.nz/#F!r9N0VK5R!WnnyYsGqwa7M-v1jckw6iQ) (I think I posted this before somewhere, beginning of Lore s02e01), the blue push is almost everywhere. Just checked out the 1080p version of it (madvr + sdr 3dlut) and there's no such blue in it, it's closer the the Saturation intents with hdr10.

As for gamma, I don't really know. There are minor differences but I couldn't tell which looks more correct.
g2.2 looks good for almost all of them, except for the 2 saturation ones, where maybe even g1.0 is not enough (but it brightens other part of the image more then the rest of the rendering intents: this is how the factory 3dlut also work!).

I found absolute colorimeric HDR to look quite similar when comparing it to HDRtoSDR.
It's way undersaturated compared to factory hdr10 3dluts here, see below.

Perceptual has less saturation in these scenes but it shifts blue too much towards purple.
Yes, I don't like this one at all.
But check out "Preserve Saturation" (-ims) g1.0 with +7 saturation in madvr (I lowered down yesterday by 1):
- by default this one also has the slight purple push, but when adding saturation in madvr, it pushes purple towards to blue
- this one look closest how I think images should look like (due to the lack of reference monitor) without having the blue push, rarely pushes more yellow orange than it should
- fire/explosion/sundown look extremely good, no more dried out grass/dirt, etc.

Try the sample above with this, you'll see a drastic difference :)
And I just watched Lights Out (2016) yesterday with it, it looked gorgeous, check it out if you can! (Video has very clean image, lot of rich colors everywhere, perfect hdr representation, and last but not least I actually liked the movie itself :) )

[j82k]

Did the C1 also have this?


In those problematic blueish scenes, like the lions king, the C1 had less saturation and it was shifted more towards cyan whereas the C8 is shifting towards purple.

I was mostly looking at HDR when comparing them, should've done some SDR too. The C1 is still sitting here boxed up, waiting to get picked up in 2 days. I could unbox it and set it up again but that's way too much effort. :)



I'm not sure about sdr here (since I use 3dlut for madvr)

Funny that you mention this because I just checked my SDR calibration folder and in april/may I did 26 SDR 3DLUTs in displayCal, with all kind of different settings and patch sets, some up to 10K patches. My goal was to fix skin tones + dark blueish scenes. But often the 3DLUT made the dark blues even more saturated or there was a noticeable shift between blue and purple or color banding/posterization. In the end, more dark colored patches would usually mess things up even more.

I guess this could be because of panel drift or because the i1Display Pro being too inaccurate when reading dark colors, or crappy TV processing, I don't know. Some of these 3DLUTs were okayish but I wasn't really happy with any of them. The handmaids tale has lots of blueish dark scenes, this is where I often noticed SDR 3DLUT issues.

Skin tones are easy to fix with a 3DLUT, at least in SDR but getting dark blue colors right is a pain in the ass, at least on my C8.



Take a look at this sample 04-2160p_23fps_hdr0999-l_s02e01_cyan_error.mkv (I think I posted this before somewhere, beginning of Lore s02e01), the blue push is almost everywhere. Just checked out the 1080p version of it (madvr + sdr 3dlut) and there's no such blue in it, it's closer the the Saturation intents with hdr10.

Yeah it's too blue, but watchable. I didn't look at that one with the C1 but I'm sure it would look less saturated and a bit more shifted towards cyan.

Maybe SDR isn't even oversaturated with dark blue scenes and I just have this in my head because of all the messed up 3DLUTs I did. But SDR dark blues are for sure too much shifted towards purple on my C8.


It's way undersaturated compared to factory hdr10 3dluts here, see below.

I mostly did comparisons with darkish scenes, so what you say could very well be the case in brighter scenes or with colored highlights.


Yes, I don't like this one at all.

Still too purple for me, I don't know how much panel variance there is when it comes to hue/saturation but on my C8 for skin tones and brownish-orange colors to look correct I need to set the tint slider towards green.
I already knew that before, but having had the C1 next to the C8 just confirmed this as skin tones looked similar with tint at about G8-G10. I also did this comparison when I had the GZ2000 and back then the C8 also required a tint adjustment towards green to look comparable, don't remember how much though.

Now the huge drawback when setting tint towards green is that dark blueish scenes now look worse because they'd need to have the tint slider set towards red.

So it's either 'dark blueish scenes looking purple' or 'skin tones looking too red', or some of each with tint at default 0.

I tried to fix this with the CMS controls but they do almost nothing to dark colors and barely anything to skin tones even when set to max.


I think I'm done with testing and 3DLUTs for now, at least until something promising emerges... :)

The C8 issues aren't too bad and at least my C8 has no near-black overshoot with black levels set to faintly glow. This tweak doesn't work on the C1 because of the heavy dithering and because it doesn't use the white sub-pixel below 3% or so.

[chros]

...
I guess this could be because of panel drift or because the i1Display Pro being too inaccurate when reading dark colors, or crappy TV processing, I don't know.
:D I can confirm this, I also tried bunch of profiling sessions, I can get a good one let's say 1 out of 10 :D Also ABL can be an issue (at least on mine, GRS). How the hack this works ... :)
I managed to make a good one back in the day, so that's what I use, probably until the TV dies :)

I mostly did comparisons with darkish scenes, so what you say could very well be the case in brighter scenes or with colored highlights.
It's not even with highlights, just normal scene, like sand/grass/tree/etc.

Still too purple for me, I don't know how much panel variance there is when it comes to hue/saturation
It can be, or you know, the used 1dlut can also modify things.

but on my C8 for skin tones and brownish-orange colors to look correct I need to set the tint slider towards green.
I already knew that before, but having had the C1 next to the C8 just confirmed this as skin tones looked similar with tint at about G8-G10. I also did this comparison when I had the GZ2000 and back then the C8 also required a tint adjustment towards green to look comparable, don't remember how much though.
Interesting. Just as you said, it's hard to create 1 that is good for everything :)

I think I'm done with testing and 3DLUTs for now, at least until something promising emerges... :)
Same here as well (probably :)), but with this it's lightyears ahead how it was before! :D

The C8 issues aren't too bad and at least my C8 has no near-black overshoot with black levels set to faintly glow. This tweak doesn't work on the C1 because of the heavy dithering and because it doesn't use the white sub-pixel below 3% or so.
Interesting, thanks for the info. As I mentioned couple of time, the macroblocking doesn't bother me at all if it's present (probably it's not that disturbing here).

1 last thing about 1dluts: do you remember when I uploaded hdr10 1dluts into DoVi presets and said that couple of them destroyed the "neon" color look (I don't know how to describe it otherwise, it's extremely visible when you switch between presets), resulting in pale colors.
Now, since we finally have a clean image with bloody hdr10 as well, I uploaded couple of those 1dluts, and I noticed the same thing!
What's your take on this, what can be the cause? Can it be the misaligned Gray scale balance?

[ashlar42]

Could somebody be kind enough to do a "differences between 1dlut and 3dlut for dummies" for me (the dummy)?

[quietvoid]

I'm not an expert but essentially 1D LUT is for greyscale and whitebalance (brightness adjustments, whitepoint), while 3D LUT is for aligning colors to what they should actually look like.

[SamuriHL]

That sums it up. If you want a deeper look at it:

https://www.lightspace.lightillusion.com/luts.html

That should help.

[ashlar42]

Thanks to both!

[chros]

LG on older sets defaults Oled light to 80 in SDR which is waaay too high. I use 33 (~120 nits) with gamma 2.4 for night, and 39 (~140 nits) with gamma 2.2 for day if it's necessary. (SDR 3dluts on top of these in madvr.)

I think I'm done with testing and 3DLUTs for now, at least until something promising emerges... :)
Then try this one out! :) This is about SDR.

Since madshi said, he won't deal with SDR2HDR for now and we have 0 black (meaning we can raise Oled light to the stars without elevating black floor), I was curious how HLG works (that's the closest to SDR+HDR), that's how I found this doc (https://www.avsforum.com/threads/improving-madvr-hdr-to-sdr-mapping-for-projector.2954506/post-60869970).

If I understand it right, they claim (by visual testing), that the knee point (they chose 80% input signal, ~58nits @100nits White and g2.4) is not that important than the actual steepness above it, and they try to map diffuse white (90%/95% input signal, ~78/88 nits @100nits White and g2.4) to 203 nits and the rest is highlight.
The interesting part is the graph on page 20, they almost follow the same curve until the knee point (they go a bit higher by mapping the 58nits to ~70nits), from there they use different curve until they reach diffuse white, then another one above that.

So, I was curious what options we have to accomplish something like that with our sdr 3dluts. As it turned out not much :)
- we have 0 black, and although faking black/relative/absolute/offset params do work on Calibration tab of DisplayCal (argyll cms), but even with the lowest settings the raised black is getting annoying

That leaves us with standard gamma setting:
- I made this sheet (https://docs.google.com/spreadsheets/d/1-pUyOz1idTL-KhMhc1Kk5yS7Ir4bgWZl2ABCNOHFqis/edit?usp=sharing) to see what brightness we get for different input signals with different gamma and peak settings (we want to compare it with the 100/120 nits values)
- want to use as high (darker) gamma as we can without black crush, because higher luminance range will be brighter anyway
- - the green lines are the gamma that I picked for each peak, by trying to match the 0,05 value to the 100 nit one (didn't get black crush with them after checking it with various scenes)
- if we use really high Oled light (peak) (>271 nits) then even the suggested minimum value of diffuse white (90%) will be really bright (>203 nits), so it's unnecessary

So, I experimented a bit:
- at first I picked the 208 nits peak one (Oled light 70 here) and I used it for couple of months as proof of concept
- later I went for 271 nits (98 Oled light here) meaning 203 nits ~ 90% Input signal, but we drive our panel really hard this way and red/orange color was too saturated sometimes (maybe it was the cause of the generated 3dlut)
- finally I settled down with 234 nits (85 Oled light here) meaning 203 nits ~ 95% Input signal

So with 234 nits (85 Oled light here):
- I created a g2.68 3dlut (and a g2.48 for bright daylight): set Maximise RBG luminance at patch generation!
- it has more than double of the peak of the standard sdr (but due to gamma the increase is way less with lower input signals)
- no balck crush
- 80% input signal (knee) is around 129 nits with this gamma
- no banding/posterization/other anomaly
- no color desaturation (even more saturation)
- brighter scenes are not disturbing during the night either

Due to the increased luminance range, we get higher sharpness, punchier / more lifelike images, while dark scenes don't suffer. Where this really shines (obviously) is with high contrast scenes including lights/shiny objects/reflections.

So, I have set up Cinema SDR preset with Oled light 85 and created a profile in madvr for this g2.68 3dlut.

(I also tried with my original 120 nits (33 Oled light here) profile:
- creating HLG curve from the same profile: sometimes madvr didn't accept the 3dlut, other times it did, bit the result wasn't impressing, I guess due to the peak 120 nits in the 3dlut
)

Note about burnin: these guys made ADL measurements with sdr movies (http://projectiondream.com/en/movie-brightness-adl-contrast-measurements/) (just as we did with HDR10 with madmeasure), and the brightest one (snowboarding doc :) ) had 32% ADL, while the average of the rest is ~10% ADL.
So, although we drive our panel harder with this (e.g. compared to 120 nits peak), but this won't be an issue with standard (low APL) video content (e.g. 50% input signal of SDR with the latest settings above is ~37 nits, while the same with HDR10 at 700 nits peak is ~100 nits).

[oldpainlesskodi]

Ok, I need help.....I'm BLIND!!! lol.

So, after a while of resisting PC mode on the LG because it removed some options that I thought I found useful, I decided, as an experiment to switch to PC mode and make some adjustments, and now I cant go back to 4.2.0 vs 4.4.4...please help me un-see the the light!

Serious note - why hide 4.4.4 that makes it so hard to enable on these panels at a cost of losing other options?

[chros]

)I also tried:
- creating HLG curve from the same profile: sometimes madvr didn't accept the 3dlut, other times it did, bit the result wasn't impressing, I guess due to the peak 120nits in the 3dlut
)
...
Next I'll try out some synthetic 3dlut with HLG curve, maybe ... :)
I did, in short I'll use the settings that I came up with previously (70 oled light with g2.64 3dlut) until madvr has sdr2hdr10 feature:
- synthetic 3dluts doesn't have any colorimetric data, colors are slightly desaturated, it has less impact
- - it was a good test for HLG, the peak brightness has a big impact of the final image (e.g. 250 vs 1000)
- same with the 3dlut I use now with HLG: it only has 120 nits peak, so maybe that's why
- we can't profile this crap at 90/100 oled light due to instability, even then maybe I wouldn't prefer the HLG 3dlut variant

So, after a while of resisting PC mode on the LG because it removed some options that I thought I found useful, I decided, as an experiment to switch to PC mode and make some adjustments, and now I cant go back to 4.2.0 vs 4.4.4...please help me un-see the the light!
So, do you like PC mode with chroma 4:4:4? :) (it's 4:2:2 vs 4:4:4, not 4:2:0) If so, tell @j82k :)
What options do you miss with PC mode?

@huhn, how is it going with your new toy? :)

[huhn]

just finished the first test calibration:
3D LUT: https://drive.google.com/file/d/1GT0hyQbN0u_M7C0GkYWgQ_b46kXUWc7W/view?usp=sharing
22 point ""calibration: https://drive.google.com/file/d/1yq4L-IbGrH76YkNJ1E4TgughskwpIRIi/view?usp=sharing

not my best work but this was a test the manual calibration took me while i did never verified it "only" fixing white point for the gray scale.

i will not play around with the internal 3DLUT yet. i have no real banding issue or close to black blocking thingys lucky bad tests?

but my screen/AMD/windows11 do something very strange 2-6 pixel are cut of the left side and the right side looks like it has space for these pixel...
edit: it fixed it self after a couple of resolution changes

[oldpainlesskodi]

@ chros - thanks for the correction lol.

Yes, I prefer 4.4.4(:!), but it's a shame that all advanced controls locked unless in ISF mode in SDR,.... in HDR mode advanced controls locked out completely regardless of mode (color gamut set to wide, peak brightness etc etc)...

[j82k]

...lots of of words ....

Sorry for not replying earlier. I'm very busy with other things so I'm currently not messing with TV stuff at all.

The C1 is gone and I'm getting a full refund. To be honest I think I would've regretted this TV forever had I kept it. :devil: It's better than the C8 in some regards but worse in others, so I'm happier with not paying a lot of money for a TV that is only a compromise. :)

I wish I wouldn't care about near-black overshoot, because then I would just buy a panasonic oled and be happy but I hate that crap and every time I see it, in my mind I bought an expensive faulty piece of crap TV.:eek: I just can not stand it and I hope I will not buy another oled until this is 100% solved on a hardware level.

About dolby vision:
I have no way of measuring DV and I rarely watch DV. The only thing I did some time ago was measure a 50% DV patch that I found and with the same 1DLUT that I use for HDR it was way too bright... So to me it seems DV needs a different 1DLUT?

[Asmodian]

Are you looking for HDR settings? I just use passthrough on my 48CX. :o

[huhn]

you are not disappointed on these screens HDR passthrough?

did you try to use SDR -Y HDR tone mapping to improve the situation?

[quietvoid]

For 95% of the (current) content there will be little to no difference between passthrough and tonemapping with madVR.

[nevcairiel]

I got a 65G1 today, going to need to break out the meter soon and figure out how all this worked, been a while since i had to touch this for my old trusty 1080p TV.
Won't have it properly mounted on the wall until next week, and going to need to install a 30-series card in the HTPC (which I already have, too) to make full of use of all the HDMI (and the 1060 i had previously is certainly at a limit upscaling to 4K), hopefully i can mess around with some measuring on the weekend.

[chros]

Congrats, Nev, ask any question ... :)

[Asmodian]

you are not disappointed on these screens HDR passthrough?


I don't watch much HDR content in the first place, but in all my testing of various tone mapping settings I found some scenes look better but others look worse. Also, it would look a bit better than passthrough but sometimes it was much worse than passthrough, the upside was smaller than the downside.

I haven't been keeping up with all the beta builds, so maybe there are some settings that are noticeably better across all content. :p

good to know not a an of the current HDR -> SDR situation too.

i don't really follow them to is more about working around the ABL as much as possible

Did you turned off Pixel shift in the TV? (That can do things like this)
I'm not bothered by macroblocking either, it depends on lot of things.
Interesting that you calibrated it at 200 nits. How much did you measure in Cinema preset HDR10 mode with your CX?

anyone have a 48cx setting they can share? like upload the settings.bin or registry , im lost on how to properly set this, currently have a new rig with a 5950x and 3090 wanted to try if thier anyone with a good max settings to try thanks
Take a look at the link in my signature for settings for 1060 6GB. You can crank them up if you like, but I doubt you will see any difference (only on your electricity bill :) ).

I found some scenes look better but others look worse. Also, it would look a bit better than passthrough but sometimes it was much worse than passthrough, the upside was smaller than the downside.
Yes, that's why I disabled DTN in madvr for my default profile half a year ago :)

Sorry for not replying earlier. ... The C1 is gone ...
No worries, me too. I agree, what's the point to pay lot of money for another device with full of issues, we already have one :D

I wish I wouldn't care about near-black overshoot, because then I would just buy a panasonic oled and be happy but I hate that crap and every time I see it, in my mind I bought an expensive faulty piece of crap TV.:eek: I just can not stand it and I hope I will not buy another oled until this is 100% solved on a hardware level.
I doubt it will be ever solved due to the inherent nature of the problem is the technology itself, WOLED :)
Panasonic is not acceptable for me either, unless they fix(ed ?) judder free 23p with chroma 4:4:4, that I doubt ... Let alone, the tools/ecosystem around LG is so well built at this point ...

About dolby vision:
I have no way of measuring DV and I rarely watch DV. The only thing I did some time ago was measure a 50% DV patch that I found and with the same 1DLUT that I use for HDR it was way too bright... So to me it seems DV needs a different 1DLUT?
Can you send me over that patch via pm? Thanks
It depends on the preset you tired: which one was it? (game preset is 150 nits lower here on B8)
I can't tell it now, because the 1dlut I use (Can you send me over that patch via pm? Thanks) produce brighter normal scenes, probably due to the elevated gamma from 30% (which I had to do to don't have fog/veil with factory 3dlut in normal/bright scenes).
So I guess, I have to go back to 1dlut creation and try out flat gamma 2.2 again with our synthetic hdr10 3dlut and DoVi. But it's just so finicky to deal with it ... :)

Did you turned off Pixel shift in the TV? (That can do things like this)
off
I'm not bothered by macroblocking either, it depends on lot of things.
i tested for worse makro blocking not makro blocking if ther eis makro blocking i can't blame the TV. it the TV would do that i would be very annoyed.
Interesting that you calibrated it at 200 nits. How much did you measure in Cinema preset HDR10 mode with your CX?
i did not measure HDR10 cinema because the problem is not the brightness is more than 200 sometimes much more it's the inconsistence that's the problem.

[Asmodian]

so i was hoping to just copy from someone, i remember it can be done by registry or a setting.bin

The third post of the link in my signature does have settings.bin for v0.92.17.

nice test: https://www.youtube.com/watch?v=Qtve0u3GJ9Y

good to see that i'm not alone on the out of the box accuracy.
i disagree with HDR which is a joke in my opinion.

and the screen is sometimes still cut of toggling the screen shift fixes it but still bad design maybe i need to update the firmware...

Do you have Just Scan enabled?
Might be different for new models, it's an aspect ratio setting.

Not sure how the screen could get cut if shifting is disabled otherwise.

[huhn]

i would know if it would over scan no it'S the pixel shift been buggy toggling it on off fixes the issue.

What TV is it exactly? CX, C1, ..
Does size of screen matter for brightness in these model series?

[huhn]

the C1 is supoposed to have a new panel all measurements i have seem show the c9, cx, c1 are pretty much the same.
there are differents but they are very low
they are the"flag ships" models from 2019, 2020 and 2021

If you disable Quick Start+ it fixes the pixel shift issues, at least on my CX. :p

i give it a try.

Any Feedback from the latest madvr build? Is it even worth it to upgrade?

Not really any difference currently, might be worth it when we start getting improvements on the flickering (or rather when we know what values are good)

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

[chros]

guys question, when i play a movie thats in hdr the color is washout when not in fullscreen mode, its only ok if in fullscreen, anyway around this?
Recent nvidia drivers work like this, which driver and card do you have?

Which TV do you have?
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 have C9 and CX.
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?

[SamuriHL]

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.

You can try this (https://www.avsforum.com/threads/madvr-argyllcms.1471169/post-60847806), but there's an issue in this case as the post below it suggests, or you can try to create one in calibration mode.
In short, I didn't like the result, so just ended up using synthetic 3dlut: you can read from here (https://forum.doom9.org/showthread.php?p=1946716#post1946716) (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 (https://forum.doom9.org/showthread.php?p=1947198#post1947198) :)

Thank you for your detailed explanation. I'll check each link and comment about them later.

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.

[chros]

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

[ashlar42]

Ok, I need help.....I'm BLIND!!! lol.

So, after a while of resisting PC mode on the LG because it removed some options that I thought I found useful, I decided, as an experiment to switch to PC mode and make some adjustments, and now I cant go back to 4.2.0 vs 4.4.4...please help me un-see the the light!

Serious note - why hide 4.4.4 that makes it so hard to enable on these panels at a cost of losing other options?
I always forgot to ask about this... I see you talk of PC mode as the way to unlock 4.4.4. And I don't get it. While not in PC mode, if I set RGB full the "mash green button" info panel states that I'm in RGB mode. What you write means it's not full chroma resolution that way?

[oldpainlesskodi]

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?p=1673852&postcount=25082 )
