Thanks alot my friend! i have got the 750 ti and the 960 on test

Now please help me with the settings :P

Here is what i got at the moment, what i can change for better results in playing of 4K H264 video > downscaled to 1080p?

You have to select 'auto' in the colour space option to get the correct HDR colours. With 'auto' it looks 'kinda' washed out, or better described: it looks like SDR. In contrast, the desktop looks super saturated and vibrant with colours. But it must be something about my hardware since nobody seems to have any trouble here. oh well.
Hi, if you manually put windows in HDR mode does you TV switch to HDR automatically? or do you not have a HDR TV and you converting HDR material to SDR using MADVR?

Hi, turn off artefact removal completely, you wont need this unless your material is or horrifically bad, this will make a real mess of a 1080p / 4k print, I've only ever used this once or twice ever.

Yes, it does. I have a HDR10 TV. It's not great (KU7000), but it supports HDR. Watching the same content with the TV player, colours look much better and vibrant.

I use madVR to watch some of the clips i shot with my S8, does this count or i should still turn it off? since when im into a bit darker parts, there is noise/artefacts, thanks

do you have your TV set in deep colour mode on you PC HDMI port?, is your PC setup as 4:2:0 10 bit, if not drop it into that mode for now as a diagnostic step.

Make sure FSE is off and Direct3D is ticked in MADVR in rendering, you should also set MADVR to passthru for HDR.

might also be worth a clean driver install, I think people have suggested HDR is now fixed with they latest drivers.

you can set this up on a key to toggle off and on, set it off by default and turn it on if your clip is very bad i'd say, i'd be suprised if they were that bad though, I have an S8 and my clips are really quite good in SDR and HDR.

This is not true. I.e. many HD sources have banding artefacts ...

perhaps we should look a this a different way, perhaps Just treat this like we would if we were choosing the card for gaming, just get the fastest 4k capable card we can for the money we have, no more discussion then required

What I mean is they are all capable 4K cards but you get diminishing returns the more money you pump into them, in my opinion so just decide on a budget and stick to it.
i agree but i'm using a 1050 with 2gb and memory is always full
Maybe with high memory i can get better results
i need also to upgrade CPU and motherboard on my htpc, i have a i5 950 with a good asus motherboarth with 6GB of ram.

anyway thx for your reply

HD streaming rips can be quite bad I know, some movies like snowpiercer also need a bit and where this does clean up the some of the mess it cripples the overall sharpness of the image so I stand by my comments, off by default, on when you feel its required... but try and avoid it.

have a think about what you want to achieve first, I have a much faster system than you but my GFX card is slower, I'm really happy with my picture quality just using NGU sharp medium, you may find after spending a crap load of money and pushing MADVR to the max you dont see that much difference in PQ, is it worth the outlay?

If you play everything well enough with the kit you have and you're not getting dropped frames perhaps just keep what you have.

With my GTX 1080, when I try to create a custom resolution for a "23hz" mode in madvr everything works nicely except that it also automatically creates a custom "24hz" mode in the nvidia panel. Unfortunatly, it is not possible to choose 12bit with 24hz in the Nvidia panel so i have no other choice than to stay with 8bit when I want to use madvr custom resolution
Is someone know how to fix this Nvidia bug ?

you are playing a 23,976 movie at 60 hz so this is why you are getting frame repeats. if you arent bothered about that and you are reffering to the screen going black intermittently i'm not sure, does your receiver screen or TV suggest there is a hdmi handshake loss?

if you change the renderer back to the standard instead of MADVR does it play normally?

I usually don't get dropped frames, except when I move the mouse cursor on the seek bar. In that case I get dropped frames, glitches and the screen goes black intermittently.
I think it's because of the last Intel video driver (23.20.16.4901 - Intel HD 520) but I'm not sure.
All the renders works good except for madVR.

yeah sounds like it, drop back to an earlier driver then to test Also, i'd set up madvr up properly, get 1080p23 into display modes in MADVR so it plays the movies at the correct rate.

Same result with previous driver 23.20.16.4849

EDIT:

It works good with driver:
21.20.16.4550 (11/2016 - from windows update)
22.20.16.4718 (09/2017 - from HP)

They are fixed! HDR works perfectly for me now, madVR turns on HDR automatically but Windows' HDR mode doesn't turn on. Ideal.

Linear light / gamma correction for upscaling needed

Hi, madshi. madvr currently has two gamma correction problems.

Please consider adding gamma correction / "linear light" to all upscaling modes. It's really a basic thing that should be available for upscaling same as it is available for downscaling.

The Jinc interpolation with the anti-ringing filter is an exceptional solution for natural-looking results with very highly reduced "aliasing" and a relatively very low amount of processing power. The problem is that in upscaling, it's largely ruined by the lack of gamma correction.

For comparison, here are upscaling results with similar, catmull-rom filters:

original image

madvr-x2-catrom-sigmoidal-off
madvr-x2-catrom-sigmoidal-on
imageworsener-x2-catrom

Sigmoidal light even makes the gamma-related "artifacts" worse.

Currently, only NGU has gamma correction for upscaling, so I'm comparing with NGU Soft, luma doubling and chroma "very high", quadrupling disabled.

madvr-x2-ngusoft

This is the same effect as what happens in downscaling, but it's much more disturbing in upscaling, because...it's upscaled. Since ImageWorsener, ImageMagick, GIMP and a few other programs give better results that are similar to each other, then I guess it means madvr just has a different, more "lenient" gamma correction implementation, but it's not better nor as good.


Example with downscaling:
madvr-x0.5-catrom
madvr-x0.5-catrom-nocorrection
imageworsener-x0.5-catrom
imageworsener-x0.5-catrom-nocorrection

Without gamma correction, pretty much identical. With gamma correction, as mentioned above, the "artifacts" are more visible in madvr.

I'll just mention that the problems are not limited to this single image. I've compared using other images, and madvr's gamma correction is always worse. I'm just using this test image because it's the best for easily showcasing the problems. I'm sure you could easily improve the gamma correction and enable it for upscaling as well, and thus make madvr not just the highest quality video renderer, but also the best video and image scaling software available. On that note, I'll just add that a custom width/height box in the screenshots menu would be very useful.
Thanks.
