Yeah I tried the loading the profile as well. Does not do jack.

I can also keep posting that setting frames presented in advanced to 1 fixes it for me but it's obvious it does not work for everybody.

Curious. What do you mean fully? So it helps? How? How not?

You need to convince a splitter/decoder dev. If you find one who's interested in implementing DV, I might look into it, too. But without an interested splitter/decoder dev, there's literally nothing I can do.
Let me try barking up that same tree from a different angle.

-> I would like to use madTPG with CalMAN to calibrate the DolbyVision mode on my TV (LG C8).
This shouldn't need any decoder/splitter support other than some collaboration with Spectracal.
Given the ridiculous price of the external signal generator boxes (which support both CalMAN and DolbyVision), I guess some us would even be willing put up a modest donation.

By the way, I personally prefer HDR10 for several different reasons, especially for videogames (since DV12 always uses 4:2:0 chroma sub-sampling, at least in it's current implementations while even HDMI 2.0 can handle 4:2:2 in 2160p60, let alone HDMI 2.1 which is on the corner). But I can't force the built-in Netflix app to ignore DV and fall back to HDR10 (while the Windows version which is limited to HDR10 has it's own unrelated issues) and most of the HDR capable games I played (or plan to play) looked much better with DolbyVision simply because the HDR10 mode is clearly implemented inproperly from a picture quality perspective (near-black shades look very similar in SDR and DV12 but look obviously too bright in HDR10 -> and no, this not a display issue, it's the game... try it for yourself with Mass Effect Andromeda. This doesn't happen with movies, only EA Frostbite games.)

Edit: Although... https://www.avsforum.com/forum/139-d...l#post57995516

Hey, I just realized we probably don't even really need a DolbyVision capable signal generator to calibrate the DV picture modes of the 2018 LG TVs. Isn't it only required to validate the results?
I am not sure since I never saw the full DV process but if it's anything like the HDR10 calibration then it's all about calibrating the panel to D65 with gamma 2.2 while most of the HDR-related processing is temporarily deactivated. I guess we could even simply copy-paste the 1DLUT between HDR10 and DV modes. And I guess the DV related "parameter upload" is also based on the native gamut measurements, so there is nothing we really need from a DV signal generator.
Or is it already suppose to work now with madTPG (picking HDR10 mode but selecting the DV workflow) and I just overlooked it?

Same here. I'm currently testing with frames set to 1. Seeking on the file succcks now though. Only been able to test ~ 15 min of viewing, but it's okay thus far. Still debating putting my 1060 back in though.

Can any experts here speak to the advantages/disadvantages of using DXVA copy back and setting advance frames to 1?

DXVA copy back has no practical disadvantages as long as your decode queue still fills up (older/slower systems can't keep up with it especially in UHD). It uses a bit more power and system resources as the decoded frames have to be transfered back to system RAM but it's negligible compared to the power needed for rendering.

Presenting only 1 frame in advance increases the possibility of having dropped frames. It all depends if your system and GPU is highly stressed or not.

@ katodevin, put the 1060 into another computer, and use that to watch movies until 20xx gets more fixed.

w/ gpu decode, should only require ~dual core sandy bridge era

The only difference between 2060 and 1060 for now, would be 2060 can do slightly higher chroma ngu for 4KHDR, WHICH makes very little difference in the end result

Hmmm, I dont have issue seeking nor with dropped/repeated frames.

What specs are you running? I am running at 4500mhz (500 OC). 16GB of ram. Stock clocks on the GPU for video watching 2000mhz/15000vram(7500) for gaming. Preemptively speaking yes I have tried running stock everything to fix stutter, didnt make a difference, even tried underclocking.

Just to be clear Set frames in advance to 1 in Madvr not Nvidia CP, you can Nvidia CP and it will work but the audio will be 300ms off and require a -300 offset. And to be honest I have not tried D3D11, it could be fine too, I just say DXVA2CB just because it worked Ill try next time I watch something.

[QUOTE=tp4tissue;1873144]BEFORE Madvr graced us with 3Dlut support, the only way to get calibrated was to buy $500 lut-boxes.

You've convinced me , 2 weeks ago , I've bought the X-rite i1Display Pro

A new adventure (and probably a lot of frustrations) starts !

Has madVR development ceased? I see the latest release is dated back in September 2018, quite a stretch when compared to the other periods between releases

You could've done a quick search to find the answer to this.
madshi should have a new release sometime this year, who knows when at this stage, the man is busy with other things.

The benefits and usefulness are immense.

All the monitors in your residence will be accurate for conceivably the next 10yrs.

Also, never loan tools to ur friends, they'll probably break it.

The lens is acrylic so treat appropriately.

haha ,no they expect me to do the work as well :-)

I have high hopes, after your extensive praises !

Planning to go for bigger OLED as well later this year (B965") , With the calibration , planning to start this weekend and also wanna dive into the MadVR Measurement thing, as well. (Have the latest beta and also a special version for ISO/BD folders, hopefully it also works on disc-burned MKV's)

Already amazed what MadVR does to 1080P and UHD files so far , took me quite a while to learn things from this thread and on AVR MadVR threads how to configure optimally. Had great help from Asmodian , Warner306, Huhn and ryryzn, very grateful for the great contributions on this thread. MadVR is pretty complicated , but great fun as well !

What I find weird is that I don't have many of the reported problems about studdering , banding and such and I am on WIN Insiders Fast Ring , plus I never do the DDUcleaner ... any other folks with a RTX2070 with similar behavior and chroma on NGU AA High, Image downscaling on SD 2 50%, image upscaling on NGU sharp > doubling High?

I think my settings are pretty high, no ? it renders usually at 25ms

I did OC my GPU with MSI afterburner, but no VOLT or MEM OC,need to redo this

One of my first thoughts was that older quad core cpus in combination with the newer rtx cards on madvr are not playing nice together, stutter. For example in games the cpu relays to the gpu and if the cpu cant do it fast enough you will get a bottleneck. I was thinking this because changing prerendered frames or frames presented in advance takes care of the stuttering for the most part for some people. There is a relationship there, although I do not know what it is.

Nvidia has pretty much locked overclocks. It is limited to power and thermals. The clocks are gonna do what they want no matter what you do in afterburner. You will get the fastest clocks at 50-59c then 60-69c and will get worse from there. Pretty ridiculous that it will throttle around 60c. I think Gamers Nexus has a pretty good explanation if you care to search it out. Basically keep it under 60c and the mem can go up to +1000 offset or so.

Since you guys are talking about CPUs... I have no issues with my stock-clocked 1st generation Core i7-920/X58 chipset combo (ca. 2008) Goes to show how very little the CPU matters.

Do the PC monitors first, once you understand certain setting behaviors and develop a workflow, then tackle the Oled.

Oled is slightly more complicated due to ABL.

Good Luck Sven. You will be impressed with the OLED from what I've read. Calibration is also a rabbit hole of sorts. Once you see it, you can't unsee it, lol.

3DLut + Madvr = Magical . !

It's not just a rabbit hole, every animal agrees, it's a very nice hole.
