yeah, we've taken up far too much of this thread with this apologies.

I wonder how I could further improve picture quality on my 2018 C8 oled with madvr. PC mode on lg oleds only work in 4:4:4 in 60hz mode and only when input is labeled "PC". in 23/24hz mode it wil not work in 4:4:4 RGB. That they are only 8 bit in RBG is new to me. My setup is GPU RGB 4:4:4, madvr 0-255 and tv set to Blacklevel high. Maybe I should try ycbcr, but that should be one more conversion step... I tried to find a good solution for hdr files. Experimented a bit with the new .16 build but couldn't find a good setting for now. If there are more oled/madvr user, maybe we can open a new oled/madvr thread were we can exchange settings and impressions...

another thread I think if people want to discuss this further, i'd be interested to know how ive managed to get rid of ABL on mine with my OLED light at 60.

New thread here, if it gets used enough it may get sticky.

What leads you to believe that? Industry insiders claim it's niche only and will stay niche, they will never be able to bring LED subpixels down to the size required for smaller screens at marketable price...

So we have 4K smart phone displays in 5", and 4K TVs in >50". Maybe it won't work in smartphones, but TVs is quite another ballpark entirely.

there is a physical limitation in size that micro LEDs can drop to apparently as they currently have to installed one by one by robots and according to some sources this just isnt possible at the small scales to produce at 40-65 inch main stream TV, have read that a few places.
maybe they will find some way of 3d printing them. https://www.tomsguide.com/us/micro-l...view-5282.html

The nit value to use into the "target nit" box in madVR should be exactly the amount of the nit value the TV is capable of, am I right?
Does exist some sort of conversion table of that value for PJs, due to the fact in this case we are talking about Lux and reflecting screen, not of emitting display? Or even an aproximative suggestion? If I well recall, the madVR default is 200 nit for PJs and 400 for digital display: are this for a correct calibration according to the HDR standard nit target?

I'm pretty sure the default target is 200 for TVs/monitors as well if you "let MadVR decide"...I don't know of any table for lux to reflected nits conversion but it surely should take distance to screen and screen gain into account as well as other factors specific to different projectors, which is a stretch, so you'll have to assume nit value of a typical projector with the given lumen output, a couple of tens of nits of difference are really not that impactful, IMHO.

Please no more discussion here about MicroLED, ABLs etc, unless it's really madVR related, thanks!
Not really. Pick any value which looks good to you. Lowering the target nit will make the image brighter, on the cost of losing HDR highlights. |

Great work on the HDR -> SDR work, looks good across a range of screens (JVC x7500, LG OLED, Sony LCD). Also tested and working well with a range of GPU's (a lowly iGPU (NUC), 970, 1070 using some preset settings.bin that nev just added over at JRiver Media Center for various "levels" of GPU).
Thanks to Madshi and all over at AVS. |

Just an FYI. I got really frustrated with Winows 10 having so many issues recently with nvidia drivers. I switched back to Windows 8.1, to tell you the truth, with the latest nvidia driver, playback of 4K HDR is fantastic without even a single glitch. I have correct composition rate (In Windows 10 it was always 23,980). HDR- SDR conversion is also working great. Really happy with the results. Thanks madshi for his nice work.

when i change the gamma in calibration it changes the image.
this is unexpected behaviour because if i calibrated a screen to gamma x i expect madVR to honor this and not change something related to the image. example why this is a problem. when i put 2 screen next to each other one with gamma 2.4 and one with gamma 2.2 than i expect an image that is mathematical different with a gamma of 0.2. but this can't be true because if i change the gamma setting under calibration the image changes and to get this results madVR has to send both screen a bit identical image. the gamma of the image should not be change just by the calibration setting it should only be changed in conjunction with "color & gamma -> enable gamma processing". that's assuming it is just a gamma setting and has nothing todo with internal HDR calculation. if it does something different in HDR calibration well... than this is not the correct place to do that. edit: this is an issue with HDR-> SDR conversation. SDR is working as expected. Last edited by huhn; 29th September 2018 at 05:48. |

@huhn: but you need to be able to tell madvr the target gamma of the tv, and you can set this independently for each screen , also HDR-SDR conversion is also some kind of "gamma processing" as under "color & gamma" section...
Here I would like to point out that addition of the option for BT.1886 would be in order for TV's with non-0 blacks Sent from my GM 5 Plus d using Tapatalk Last edited by mytbyte; 29th September 2018 at 07:57. |

if madVR changes the image than your gamma is not your gamma anymore it is something else. Quote:

On the first point - still don't understand why you think it's not honored? There is nothing to be honored - HDR processing needs to know the TV's gamma, while SDR video has no gamma defined and gamma setting has no effect, but you need to manipulate HDR gamma.

for what do you know what type of gamma a TV has? and why should you instantly change something. change means you don't get your "gamma" anymore.
the HDR -> SDR conversation produces an SDR image. if you tick the default setting "disable calibration controls for this display" you will get on a gamma 2.2 calibrated TV a relative gamma of 2.2 on a 2.4 a gamma 2.4 you know what i mean. because every screen gets a bit identical image and everything is working as it should. but as soon as you select "this display is already calibrated" with an option that is not 2.2 you will get an altered image. so the 2.4 calibrated TV doesn't get an 2.4 gamma relative to a gamma 2.2 calibrated TV. HDR or not this is incorrect if 2.4 is not 2.4 relative to 2.2 it is not 2.4 it's that simple. don't change the image by just setting a gamma at this option or user don't get there "gamma" of choice. |
