Well that sucks, so what your saying is MS uninstalls nvidia and then re-installs a fresh clean version? What the hell, lol. I'll wait to see if anyone else is reporting this issue before I upgrade.

I can't get HDR switching to work in 1709 after upgrading from 1703 + nVidia 387.92 (was working last night). I tried a clean re-install of the last nVidia driver (385.69) and made sure my settings were nVidia color, but still doesn't work.

I'm going to rollback to 1703 unless someone here can confirm it's working for them.

It seems nvidia 3D Wizard is working now after upgrading windows 10 Fall Creators.

If that follow what I did is open PowerDVD 17 with 3D movie, it said your 3D hardware only supports the viewing of 3D movies in full screen mode. so I forgot 3D was not enabled, I get inside nvidia control panel and enabled 3D , it opened 3D wizard and didn't crash while powerdvd was still opened. so that's it. maybe it was Windows issue eventually lol..

Madshi,

For film sources, I think AS linear light can be removed. From my ISF calibrated display, it boosts the contrast and could cause eye strain on prolong staring at the screen.

Try 385.41 - working here with the fall update (1709) for HDR (windows HDR slider off, and entire chain set to Full).

There are sources between good and bad.. I find 1 and 2 to be likely the only strengths I'll ever use.

I don't really see >6 being too useful so how about middle-ground steps between the current 1-6 to go 1-12 please? Or go 1-24 if you must provide highest strengths to Vaporsynth users.

Yeah I got that but unchecking blurs the picture IME, even @1.

While we're at it, I kinda wish mVR would use proper chroma alignment for MPEG-1 but I guess it's very low priority so until then I gotta force MPEG-1 to use ffdshow and output RGB32

- change the nvidia power setting to adaptive, same thing...shuttering
- checking GPU-Z if the PCIe speed is at least x16 2 yes, but when play all gpu ram is used, maybe this is the problem?
- reduced the render queue to 6 and 4, same thing...shuttering


if someone confirm that my hardware is ok, i'll continue to try, if no my hardware need an upgrade!
maybe "EVGA GTX1060 Scheda Grafica da 6 GB" + "new CPU and motherboard"!


PS:
On my tv, lg 65b6v i set "HDMI ULTRA HD Deep Colour" option
when HTPC start is already in HDR mode.
When mpc-hc start playing UHD HDR video, using madvr in window mode it say "HDR", but when i double click and use full windows/exclusive mode, the "HDR" vanish, go out, bye bye.....this is normal?
I try with madvr, native, copy back, etcc...same thing.
If i dont use madvr, then HDR is used in full windows/exclusive mode too!

Same with powerdvd.



suggestions?
thx all for your help

The type of blocking its designed for is not quite common with HEVC. HEVC is more likely to blur on low bitrate encodes then block. Of course you could transcode a low-quality mpeg2 source to HEVC, but you only have yourself to blame if you do that =p

That is not exactly unexpected when installing a OS upgrade like the FCU.

[ttnuagmada]

Forgive me if this has been discussed.

How would I go about creating a 3dlut for 4K HDR videos, that would take advantage of my SDR television's (panny st60) native color gamut? I have a colorimeter/spectro/calman and have played around with it some, but i can't figure out what the correct way to do this would be. Any ideas?

no question. HEVC and AVC both have a very effective deblock filter and both will rarely if ever generate blocking at least in the hands of an "good" encoder. that doesn't change that AVC broadcast has usually blocking in it don't know if the professionals that disable the in loop filter for broadcast are to blame or if it comes from signal errors both should apply to HEVC too.

never underestimate the skills of a professional encoder I can show you a relative new BDs with ~20 mbit that has unbelievable blocking in it and no they are not using mpeg2 and i can show you even worse things on older discs...

set it to native gamut. try displaycal with the setting "video 3D LUT for madVR HDR..."

Im sorry, i should have explained; I have no issues with generating 3Dluts for MadVR using Calman Enthusiast. It created an excellent 3Dlut for SDR content. I am just confused on what what my targets should be for HDR, should I be trying to created a 3dlut for rec 2020?

I have used DisplayCal in the past for 3dluts, but it seems to have trouble with nailing down near-blacks on a plasma. Calman does a better job, i am just not entirely sure how this all needs to be configured to get a 3dlut that will take advantage of the extended gamut for HDR videos.

[huhn]

i don't know if calman supports a HDR -> SDR conversation 3D LUt.

madVR support both HDR -SDR 3D LUT and HDR-> HDR 3D LUt's.

but what i know is selecting a different target is not enough.
edit: well you could create a SDR bt 2020 3d lut and run this but madVR can do better HDR->SDR 3DLUT.

hi @madshi

there is a crash report here

v0.92.7 & v0.92.6 crash

v0.92.5&v0.92.4&v0.92.3 unknow，not test


crash step：
1、play a movie file
2、full screen
3、pause play back（don’t touch anything，just stop）
4、auto close screen（by power management setting）
5、wait 1 minute more
6、open screen（move mouse or touch any keyboard）
7、you can see crash now

other info：
win10 x64 15063、mpc be x64 v1.5.2、lav x64 v0.70.2、16G ram、i7 4760HQ、iris 5200

there is a crash report and settings.bin

madVR - crash report.txt
settings.7z
i hope this information is useful for bug fix

I've been struggling with several combinations the last week, since (all of a sudden, probably a TV FW upgrade) switching to HDR resulted in a purple video image. I can work-around this problem by toggling the TV OFF & ON again.

Here's my results with several drivers on Win 1709 with an 1050Ti card:

378.92-desktop-win10-64bit-international-whql
No HDR option in windows, unusable.

382.33-desktop-win10-64bit-international-whql
Toggle HDR ON/OFF on Video Start/Stop works fine, but purple video / wrong colorspace

384.76-desktop-win10-64bit-international-whql
Toggle HDR ON/OFF on Video Start/Stop works fine, but purple video / wrong colorspace

385.41-desktop-win10-64bit-international-whql
Toggle HDR ON/OFF on Video Start/Stop works fine, but purple video / wrong colorspace

387.92-desktop-win10-64bit-international-rs3-whql
HDR doesn't turn OFF after video stop, but this is the only driver that gives me good colors. Unfortunately unusable because it doesn't switch HDR ON/OFF properly.

So i'm sticking with 385.41 for now

As a sidenote: After installing the 1709 update, my desktop colors were really dark. I got this solved by running Display Color Calibration.

Other tips:
- Try reducing your decode ('CPU') queue too. When using DXVA Native, the decode queue is kept in graphics RAM, so setting it lower could help. Hardware decoding on the Pascal cards is so fast that you don't really need a very high decode queue anyway, it fills up nearly instantly. Try something like 10.
- Close all other programs when playing a movie. Any open program uses video RAM for its application windows textures.
- If it still doesn't work, try this with DXVA Native: Present queue 4, Render queue 6, Decode queue 8.
- Did you try Windowed mode? It works quite well on my 1050 Ti on Windows 10.
(Edit) - Probably not linked to your issue, but I see you have not enabled VP9 hardware decoding. Is there a reason for this? Your 1050 can decode VP9.

What do you need to change? What is becoming worse? I find audio decopding to be pretty bulletproof these days.

As huhn suggested, you don't have to do anything else: leave your native gamut 3dlut configured in madvr and it will take care of the rest!
Thanks Madshi!

I assume you are using Nvidia Control Panel to change colors right?

You change color in Resolution tab?

I wonder if none of you had trouble trying to switch from RGB to Ycbcr before?

I needed to do some weird rituals for the drivers to assume RGB FULL color. Restarting OS. Changing other options in Nvidia Control Panel. And as i never trust this driver i always check if RGB Full is selected on my Nvidia Control Panel before i watch a movie.

I remember AMD was worst.

My tip is if you get a driver that works wonderful for what u do daily u should avoid any updates. And as for windows 10 updates i have it turned off by default on services.msc. When i remember i turn on. See the info about the update and Update or not. Then OFF again.

It depends. Dolby Digital Plus from amazon prime streams is awfull and very badly mixed most of the times.
