I prefer this as my primary sharpening process.
I totally agree with this as well... I don't use any other upscaling refinement or image enhancements.

Do you use a 4K display?

No, I prefer NGU Soft more, since not only the picture, but also the hardcoded subtitle looks more natural with NGU Soft, comparing with NGU AA.

I don't think NGU Sharp is too sharp when you upscale 1080p to 2160p. Any reason why NGU AA would be better here?

There is no right or wrong, the majority is down to personal taste. It is the same with people asking for settings for a certain video card, there is no point. Some like a sharper picture, some say that in itself creates issues, so whatever you like is what matters.

If you are rolling in money, why don't you just upgrade your GPU? The GTX 960 is getting old. I don't understand the argument that an OLED will improve image quality but a GTX 1060 - 1080 won't. You aren't using the maximum settings. They aren't meant to be a placebo.

Also, there are still no 4K displays with HDMI 2.1 or any that can display an HDR image up to 4,000 nits without tone mapping with an infinite contrast ratio. 4K HDR is still in the early adopter phase.

a lot of this is getting into general territory and spamming the thread a bit, if people genuinely want to thrash this out why dont you go to the general thread.

- remember MADSHI has to read through all this, its just a waste of his precious coding time

Some time ago madshi posted this

Is it still up to date to prefer Windows 8.1 and NVIDIA?

For the moment I'm testing with AMD RX560 and Windows 10 1809 Enterprise and KODI DS 17.6, but sometimes the screen gets no signal after a movie finished and I must reset the PC.

ive had that myself and still get it with 3D movies. (no longer crashes PC though)

As a test - Do you have Full screen exclusive mode ticked, try that. Also remove any 1080p display modes from MADVR if you are upscaling everything to 4K, or use refresh rate switching on you video player instead

Are you sure its crashing the PC, try RDP on to check its not just lost HDMI link.

I have no success to enable FSE. It's enabled in madVR und Kodi.

Indeed, it's no crash, only lost HDMI-link.

ok then, turn off refresh rate swithing in MADVR and turn it on in KODI, see what happens. Make sure you've also got FULL SCREEN WINDOWED enabled in KODI DS as well.

one other thing that might help, create a batch file you can run from a key press or remote, put this in it, run this when you lose HDMI, it should come back but in 23hz mode, then create another batch file for 2160p 60hz, you could try going straight to 46k 60hz but this doesnt work for me, seems to be a bug in driver or MADVR.

So its me again I have now to ask for tomorroe cube measurement for 3d lut creation. I have a 3d lut for sdr with 100nite gama 2.4.
I will create tomorrow a lut for bt2020 sdr. Maximum nits 310 I can get without hdr flag. So 310 are my max nits on TV b7 with an apl25 window. Will this two LUTs work for doing the tonemapping hdr to sdr with madvr? Htpc control will be meassure then Friday my files so I can enjoy testing between hdr pass-through and hdr > sdr by madvr.

Just a quick poll for you guys:
- What nvidia driver version do you use on Windows 8.1 and with which card? (you can see mine in the signature)
I'm mostly interested in pascal cards but others also can be interesting.
(I'm not interested in Win10 users , we already know a lot about it.)
Thanks!

On my 8.1 HTPC I always just use the latest from whenever I updated it last. They don't usually break 8.1 drivers regularly, the repeated breakage is only on 10 since MS keeps changing things and NVIDIA is catching up.

Cheers, that's what I used to do as well, until: I noticed (by accident) that they changed how the different power states and their corresponding voltage work for my card with > v36x drivers. Hence I got back to v355.98 and never wanted to upgrade it again.

hello to everyone, return after months to ask for a review and advice, and if I can improve the quality of vision, as a test bench I always take the tv series "the walking dead" because it contains video noise, the file is 1080p, my settings are:
artifact removal-reduce banding artifacy (active)
default debanding strength (low)
strength uring fade in / out (high)
reduce compression artifacts -2-quality MEDIUM
all the other in default.

chroma upscaling: NGU -sharp, medium quality - everything else in default.
image upscaling: NGU standard-algorithm quality medium- everything else is "let madVR decode".
upscaling refinement - all in default (here I do not understand the functions)

I must say that with these settings of mpc + madvr have improved compared to vlc or kodi17.6, a little better there is, but no more, you can still improve? any suggestions / advice?

310 nits can work for HDR -> SDR, but the image will be too dim.

Your B7 can reach 768 cd/mē with HDR output. You are probably giving up too much brightness. You want to avoid tone mapping the SDR range (0 to 100 nits), and you usually need around 500 nits peak to do this. The HDR -> SDR image will be dark and flat when it doesn't need to be.
