GM204 GTX 970

i tested this heavily now for 4K nothing above Lanczos4 makes really sense here Realtime.

And Lanczos4 Performs also really well on Nvidias Shader Compiler, it shows really great and stable Render times and a visible improvement over Nvidias default DXVA.

So all in all it has a great overall Balance that really works out well

under 5ms most of the times super nice latency




PS: Yes after suspend Refreshrate shifted again to 60

Hi,

I would like to ask a question:

I've tried a 10bit pattern on madvr to understand if my tv supports 10bit output and seems it is.

Activating 10bit output in madvr produces a strange effect on 8bit videos, their colors become over-saturated (exclusive fullscreen 10bit), if i go to windows mode (8bit) they are ok.
The question is: is that normal ? it is not possible to play 8bit content correctly if output is set to 10bit ?
It happens both with mediaportalp and mpc-hc.

thank you for any answer.

that is bot normal and color saturation shouldn't change.

try a level test pattern judge from that result and stick to 8 bit.

It recommended that setting to use for 4K film I have a 1080 gtx card

I did one with a xrite i1 on my benq w2000. It appears that a 3DLut on a DLP projector isn't more efficient than a regular calibraiton. In my case I couldn't see any color difference between 3DLut calibration and the factory REC709 calibration. So, in my case, I disabled my 3DLut profile in madvr, as it ate a bit of luminosity overall.

could you please be more specific? what pattern do you suggest to try? do you have a link ? thank you

We are on a trend that mostly every avg Consumer Device now reaches REC 709 pre factory perfect, professional calibrators thus start to concentrate on P3 and above and even P3 is pretty nicely hit for a relatively nice price pre factory, great times

Not only REC 709 Mastering quality reached AVG Consumer but also P3 is pretty fast on that way future content is dictating it it goes pretty fast now

Wow, I did'nt know this topic is dedicated to 3k$+projector members

P3 is not reachable on my cheap projector, as far as I know.

[CruNcher]

Projectors will obviously take longer more bucks to be made with other Price Category

thank you for the answer, but i don't understand what you are suggesting, i've wrote that I've already tested with gray bars if my tv is supporting 10bit, and they are correctly displayed in exclusive 10bit mode . the problem comes when i try to play any 8bit video (also the very old calibration video you liked above) in eclusive 10bit mode , i get over-saturated colors. If i switch to windowed 8bit mode colors became ok. Also seems that color&gamma proprieties are not applied by madvr, so recalibrate for 10 bit output is impossible. Could it be a issue of Amd Apu gpu driver ? or am i missing something else. Thank you for any help

Guys, I'm having problems with getting HDR to work.
I have an HDR capable TV (Panasonic dx780) and I have set madVR to passthrough HDR to my display but the colors are washed out and HDR mode isn't triggered.
I'm using HDR demos and they work when played through USB. What am I doing wrong?

[dipje]

As far as I know, you're not doing anything wrong.

You can't 'trigger' HDR mode as you say it from a PC (or MadVR can't yet). You need to manually tell your TV to enable HDR processing.

Written as someone who does not have an HDR tv so I'm not up to speed on all the latest HDR-developments.

[Damien147]

It's written in the settings that you have to enable it manually(from tv) for now.I also get washed out colors too but I thought it was because I have ''pseudo'' hdr.

Regarding this:



when watched on 720p projector.

Do you have any of the black bar options enabled? maybe madVR is detecting a black bar of 1-2px at the bottom and zooming it away.

Ok. As madVR detect "touch windows from inside" try enable "disable scaling if image size changes" to some high value (and completely disable hard coded black bars detection to debug). And then try to view movie in natural size.

There are no black bars zoomed away and the "disable scaling if image size changes" setting only works if not doubling the movie.

In the meantime I have found out (I hope so) what´s going on.
In madVR´s OSD the movies are shown as 640x360. In MPC HC´s movie properties within the mediainfo part they are shown as well as 640x360. But in properties - details part the movies are shown as 641x360 (movie of first screenshot) or 640x361 (second screenshot).
I think I can´t handle this problem with the given setting possibilities in madVR at the moment. I can crop the borders within madVR, but only ALL borders at the same time. So 641x360 -> 639x358 ; 640x361 -> 638x359. They are doubled then. 639x358 -> 1278x716 ; 638x359 -> 1276x718. And then scaled to 1280x720.
The "disable scaling if image size changes" of course works when displaying at 640x360 and no scaling at all. But this doesn´t work with first doubling and do further scaling afterwards.
Of course my hardware is a little bit oldschool being 720p, but the problem will be exactly the same when e.g doubling 1080p to 2160p and having movies with not exact 1920x1080.
Maybe I have overlooked a possibility within madVR, maybe "misusing" certain settings that aren´t originally intended for doing that...
So what would be needed is an option for cropping single borders. If I could crop the single line or the single additonal horizontal pixel before doubling, then everything would be fine...

READ the page you set madVr to "passthrough" HDR.

this question come about every 2 weeks and everything you need to know is written on the setting page.

the major difference between 8 bit and 10 bit madVR output is that the high bit deep data is dithered to 10 not 8 bit the rest is the same.
so the same gamma settings are applied same scaler same everything.
so what do you understand under "over-saturated colors".

AMD high bit deep output works totally fine and madVR isn't doing something special either. so this leave you with your TV. so what TV is that and be aware that nearly every TV out there even the HDR ones are 8 bit.

'washed out colors' is a cleartale sign of the wide-gamut colorspace of HDR content being interpreted as 'normal'. In other words, it's not interpreting the video signal correct and handling it as something it's not (like, it seems it's thinking it's a 'regular' bt709 signal while you're sending bt2020 data).

The thing is I don't have any option on my TV to manually enable HDR.

Doesn't change much about what is said, right? I think 99,99% of us are not using a PC to play HDR content, because there is no real support for HDR on PC yet (not in the video-api world). No standards to 'flag' the HDR data, so no support yet.

but question is where it is implemented

1. Definitely, problem is inside streams
2. AFAIK, ffdshow or avisynt will help

Hey guys,
I've found the source of my problem, i was using lav in native and not in copy-back, now (cb) it is possible to use color & gamma setting to adjust 10bit output mode.
Thank you now all is perfect
