I made all the recommended Settings in (NUC + MPC-HC + madVR) i Follow guide in (AVSForum)

But I have a problem When you open a movie

Small screen madVR working Good But when you show the Full screen

The image is abnormal I fell Like too too much Judder

look at this

https://www.dropbox.com/s/poel13lspo...D9%A5.mp4?dl=0

This problem appears when used madVR

When using the default Filter , No problems .

I dont think you system has the power to run MADVR at whatever settings you have it set to maybe.

A few things to check.

- Are you outputting in 1080p or 4k?
- try setting all scaling to lanczos
- Make sure you've got your display modes set correctly, if you are not
using 4k try just putting 1080p23 down in the display modes.

Also, play a movie and press CONTROL+J and take screen shot (F5), post the results.

So whats the difference between NGU Sharp high and NGU Antialias high?

NGU Antialias still the best chroma or Sharp is the real deal?

[ryrynz]

AA is for lines and jagged edges it's much softer than sharp.

Keep with AA for chroma it's probably the most natural and offers fast performance for low/medium and high settings. Very high is imo a waste of resources with chroma and offered little benefit.

Just wanted to say thanks for the help/input everyone.

This is one of the reasons why I'm still with 385.28, as it's the last version that fully works.

I posted this about a month ago in my guide. Thought maybe I was the only one. Thanks for the 385.28 tip. I've been on 385.69. Before I install it, any detriments? I remember around that time there were 3D inconsistencies and if so I'll forgo the custom res until a fix.

Windows version:
Windows desktop resolution:
Pixel: eg, 4:4:4 Full rgb or 4:2:0 YBCR
TV details, 4k?
HDMI cable speed, 18gbps?
Madvr colour space setting, 16-235 or 0-255
Graphics card model:
Graphics card dynamic range setting:
do you use a receiver or is the PC connected direct to the TV?
Do you have a 4k bluray player, does it do the same thing using the same cable and HDMI port?

Pixel 4:4:4 Game Console or HDMI 1 Inputs tv setting Full RGB Set in TV settings ( Black Level LOW) , Nvidia set Limited
TV LG OLED 4K 3D 55C6
HDMI Cable tried 2 Monoprice Premium HDMI cables 1.5 Meter and also some brand that cost 38$ which is Highest possible, the same.
MadVR 0-255 which has the issues but HDR looks amazing, 16-235 the white dots disappear but the quality is lowered by 50%.
INNO3D 1080GTX Default Color Settings
No Reciever, Straight to the TV HDMI1 , I tried also HDMI2 , it's the same.
Don't have Bluray Player, downloading movies from the internet.

This is what happening for me in movies. but this guys posted for his PS4 , it's the same issue.

EDIT : found the Issue and the FIX
I think I've found the issue..

I need to change the NVidia settings from Default Color to NVidia Color Settings then choose YCbCr422 12bit Limited . Then the HDR movies works perfect with 0-255 on the TV. When using the Default it uses automatically 12 bit RGB ... so it does some weird conversion in the mode which causes issue with white pixels . I need to choose every time I watch HDR to put 12 bit YCbCr 422 so it won't try to use RGB.. is there any other way to that ?? so many manual things to change.......

With the PS4 it's the same thing. I don't have PS4, but from the youtube video I can understand the issue so it's not standalone part to the TV.... the TV doesn't go into the right mode properly . but there it's a game, but still you can play games with 12 bit RGB . HDR needs to be YCbCr 422 . so I think that's the issue in mind.

Maybe I was not clear (english it's not my language): the HDMI output (both audio and video) goes from the graphic card to the external DAC, that process only the audio (decoding all the formats but dolby Atmos) and leaves the video untouched from its HDMI output, but with the resolution limit of 1080p.

So, (assuming that the DAC is able to perform a downscaling from higher resolutions, otherwise the next part is nosense) I can't connect a 2k or 4k display to his HDMI output without having an upscaling from the display processor (worst than the one madVR provides) after the downscaling of the DAC.

In few words: GPU 2k (or 4k) -> DAC 1080p -> display + upscaling.

Using the second HDMI output I can go directly to the display at its maximum resolution and to the DAC just for the audio, without using its HDMI out (loosing, as said, the exclusive mode in madVR).

However, the DAC (I should had say preamp) is an Optoma AVP18

yes, you need FSE on Win8 for 10bit, and it only works with new path not the old path using dx9, and using dx10.

Use another HDMI cable!! Your problem is a typically HDMI cable problem. The data transfer it too high for your HDMI cable. Everything tweak that lowers the data speed will fix your problem, but this is not what you want. Try another cable.

No downside as long as you don't need a more recent driver for games or whatever reason. For 3D, you need the workaround I posted earlier in the thread. That's the only way to get 100% reliable 3D playback with nVidia as far as I can see. 3D also needs FSE, at least here.

You have to enable 3D manually before every playback to be sure it's on. I use a batch file launched from my iPad when I select the 3D button in iRule. It enables 3D on nVidia using MCE Controller and selects my 3D calibration on the projector. The register file added by Madshi after we had this discussion isn't enough for me, but it might work for you.

@x7007: You are wrong.
HillieSan is right.

What you are seeing is a very common issue with HDMI cables that can't handle higher bandwidths. Try another HMDI cable.

btw for best quality, you should set your TV Black Level to high, nvidia and madVR to full 0-255 and then calibrate brightness and contrast on your TV.

Hi, I did say a while back I also got white dots when there were bandwidth issues, this is one of the reasons I run my HTPC at 4:2:0, I dont play any games on it so this I find is the most convenient option as I can just leave it as this and it works well for everything without having to change any settings depending on what i'm doing.

Glad you got it sorted.

[mclingo]

I dont think the white dots is the cables, i'm using these decent cables end to end - https://www.ebay.co.uk/itm/JuicEBitz...53.m2749.l2649.

I get these sometimes when playing HDR movies at 4:4: 4k@24hz, if I drop to 4:2:0 its fine.

I guess it could be an issue with LG 4k TV's maybe, or my AMP but they both should support the current HDMI 2 specs.

Don't guess, try a few cables.

[el Filou]

The thing is, if it was a problem with the TV processing it would manifest itself in a more consistent way than random white dots. For instance, if it was a problem with processing brightness values or something, it wouldn't be random white dots it would be whole zones of the picture affected and it would not flicker even on a fixed image but be stable. Truly random white dots has been a symptom of bandwidth or signal integrity issues since HDMI 1.0
Even if it persists after trying many cables, it could also be an issue with the TV's inputs or the graphics card's output. Did you also try other HDMI inputs and outputs (and multiple cables on each)?

it is time. We need Dolby Vision support more than ever!

Do we really? I would argue that madvr can already make an image better than some of these pre processed Dolby vision tv shows by processing non Dolby vision video.

The issue is Dolby discs, I have a few Dolby Vision UHD blurays and they don't look as good as they could.

There is a second video track included in the stream, it is only 1920x1080 and black and white. It looks like extra information for shadows and highlights but nothing we have now can use it. They still look pretty good in HDR10 fallback mode though.

I have been unable to get HDR content to look as good in SDR mode as it does in HDR mode, at least on my OLED TV. It can look pretty good but putting the TV into HDR mode does improve highlights, shadows too but highlights are the biggest change.
