So any news on fixing exclusive mode in windows 10. Or any windows 10 hidden setting that might be in the way of allowing madvr or any 3d app to control the Full Screen???

Exclusive mode for me is the only thing tha gives me the best PQ and performance.

It is also likely the 1080p channel is 1080i, the 720p channel is 720p and the 480p channel is 480i. The performance requirements placed on madVR will be very different depending on the channel, so it is good to make separate profiles under scaling for 1080p, 720p and SD...
I'm in USA using Comcast cablecard. Looking at my tv channel frame rates using CTRL+J:
1080 @29.970
720 @59.940
480 @29.970

Not sure how to identify if it's interlaced or progressive?

I am quite happy with my RX 480. The only thing I am hoping for is that the performance of NGU will be improved for AMD.
out of interest, are you outputting to a 4k HDR tv?

Sorry, I didn't read your initial message carefully enough, so my last two posts were not as clear as they needed to be.

The 1080 @ 29.97 is likely a 1080i60 broadcast. The interlaced field rate of 60i is equal to 29.97 fps. The interlaced field rate shows two half frames, which combine to make one full frame. madVR should deinterlace this by matching each half frame with a new frame to make it 59.94 fps progressive.

The 720 @ 59.94 is a 720p60 progressive broadcast. I thought madVR might read this as 29.97 fps, as it is 29.97 x 2. At any rate, no conversion is necessary because it is a progressive signal.

The 480 @ 29.97 is likely a 480i60 broadcast. The interlaced field rate is deinterlaced by matching each half frame with a new frame to make it 59.94 fps progressive.

For the interlaced channels, the OSD should report deinterlacing as "on" and show a movie frame interval of 16ms (which means it is outputting 59.94 fps) as well deinterlacing should show in the rendering section at the bottom.

huhn recommended using YADIF deinterlacing in LAV Video. I'm not sure if you have to disable deinterlacing in madVR. Deinterlacing can be done by the decoder, video renderer or display. LAV Filters is probably the best option here. With LAV doing the deinterlacing, madVR should report the frame rate as 59.94 fps.

In practice, the output frame rate will always be 60 fps, so this shouldn't impact your madVR performance too much from source to source. You still might benefit from creating separate profiles for your content.

Here are some profile rules if you want to use them. I wrote them in a way that accounts for non-standard resolutions.

Create these profiles under "scaling":

if (srcWidth > 1280) "1080p"
else if (srcWidth <= 1280) and (srcHeight > 720) "1080p"

else if (srcWidth > 960) and (srcWidth <= 1280) "720p"
else if (srcWidth <= 960) and ((srcHeight > 540) and (srcHeight <= 720)) "720p"

else if (srcWidth <= 960) and (srcHeight <= 540) "SD"

Set the desktop to 3840 x 2160p, 8bpc, RGB Full. Set madVR to 8 bits. Set your display’s HDMI black level to full range to match the GPU. You could also try toggling smooth motion and see if you like it. As stated, NGU low to mid or super-xbr are good choices for scaling.

Mclingo,

I know from here and on the dsplayer forum, you have had both color mapping and clipping issues, as I have (hdr and non-hdr).

After much hair pulling, I managed to get to the bottom of it on my set-up.

I always thought that the best setup was Madvr Full Range, GPU RGB full range and Tv set at full range.

However, on my Samsung 4k suhd ks8000 set, this resulted in the wrong color mapping and clipping in blacks and whites, for non-hdr, which was further amplified for hdr material especially,

On my set up, what fixed my issue was changing to the following settings -

MadVR - Full Range

GPU - Limited ycbcr 4.4.4 at 12 bit for 23.976 (custom mode, ycbcr 4.4.4 8bit at anything above 30hz) and NOT rgb full range.

TV - HDMI Black Level set to Low/Limited (I can only assume that, as with my Samsung set, once it is receiving ycbcr 4.4.4, the option to chose between Normal/Low or Full/Limited is disabled).

This may, or maynot on your set up help (along with one of my previous posts regarding disabling the windows color management system).

All the best,

K

And BTW, before anyone gets all elitist on my backside (which, I am ashamed to say, is prevalent is this forum), I was the product/firmware tester for the Tomacro limHD200i when we were trying to figure out how the hell to get MKV's to play on a hardware device, and I cracked it....Madshi was on that forum back in 2007....

In the way back time machine, I sold all my VHS tapes and went Laser disk with a Pioneer CLD-D925, and had an issue about how to get true AC3, and by going on a forum. I learnt I needed an RF Demodulater...

Forums are there to share experiences, and learn - the moment anyone is slapped down (or worse, treated with disdain) by someone that consider's they know everything, it all falls apart.

I love what Madshi has done for the AV community that care about PQ quality - he has done (along with Nev) some amazing work - if everyone knew all the answer's, do you think MadVr or Lav filters would have been coded?

Anyways, onward and upwards.

thanks for the update but I fixed mine the other day by installing an older driver, then dropping back to a newer one, 18.2.2, i'm staying on this driver for now as my PC is just for movies and internet as I'm never chasing newer drivers for gaming etc.

As it currently stands everything works as expected with no need for custom res or funky setups, however i'm currently in 4:2:0. Ill be going back to 444 permanently when I'm fully happy my system is stable.

The reason Im not using 18.3x drivers is that they cause my PC to hang intermittently and randomly.

ive not noticed any clipping in HDR though, my only issue was the blown out reds.

yes I am, to a Samsung 49KS7000 and a JVC X5000 4K projector. I use HDR only for HDR movies.

I just exchanged my GTX 1070 from my Htpc to my gamig rig. My RX480 is now back in my htpc.

Is there anything I need to know in regards to madvr? I know that it is not as powerful as the gtx1070 with NGU.

What about automatic switching with hdr files? does this work differently with amd cards?

Hi, do you have FSE and use DIRECT3D11 unticked in MADVR?

Is your TV in PC mode or Bluray/media center mode?

FSE unticked and Direct3D11 ticked.
You need the latest LAV filter (nightly build) for Direct3D11 to work.

TV is in default HDMI mode with Full-RGB HDMI signal. I think PC mode works fine as well.

Hi, what do you mean you need the latest nightly, DIRECT3D 11 has been working for ages on my system, its required for HDR to work.

What does it fix?

Hi, there are a few used RX580 cards now on ebay for around £200 so prices have come down a little, they are all 4gig though, I currently have a 4 gig RX 460, can anyone hazzard a guess how much more MADVR grunt i'll get from this, roughly as a percentage, trying to work out if its worth selling the RX460 and getting one.

You should be able to run NGU high plus some artifact removal at 1080p -> 2160p. But I haven't heard from any RX 580 owners to confirm. AMD Polaris still struggles with NGU image scaling.

At least for SD that's most definitely not my experience. I find yadif results really subpar.

No, 4GB of VRAM is just the right amount.
