I was quite surprised by the result I got. However, the xbox one at RGB FULL showed the exact same problem that I got when I set madvr and gpu to full. Quite depressing as I don't see this issue with 2D playback, hence why I think I want to try a profile and set it to limited only for 3D. Very strange but at least now I know what's going on with it.

1) I wanted to find a way to rule out the HDR metadata, so I used the Vertex to capture the full metadata sent by the GPU when the OS is set to enable HDR (here it is FYI, with the header: 87:01:1a:b0:02:00:c2:33:c4:86:4c:1d:b8:0b:d0:84:80:3e:13:3d:42:40:a0:0f:32:00:e8:03:90:01). I then set the OS back to HDR off. 2) I placed an Integral between the AVR and the Vertex and I used the Integral to inject the exact same HDR infoframe (the OS was still set to SDR). I was able to switch the display to HDR without any magenta issue in 4K60p RGB 8bits. So as expected, this is NOT a metadata issue or a bandwidth. It's something else done by the GPU. I discussed this with HD Fury and they have identified the issue as being caused by the AVI Infoframe. They are working on it. I'll keep you posted when I have some news, but I thought this interim report might be useful, in case it helps you to figure out what the nVidia API is doing wrong when you call it. This is purely intended to provide you some feedback, I've followed your suggestion and am using profiles to disable metadata when fps is above 30, so from a user point of view I'm sorted for now.

I don't have any details yet, I'll let you know when I do, but I don't think they have a JVC.

I also had to change the 'hdmi black level' setting -which is an option for 16-235 or 0-255- from full to limited. Or else I would get washed out blacks. Now it looks great. Thanks for your time. |

I use a 1920*1080 full hd monitor, and mpc-be. Zoom settings in madvr are configured to move subs to the bottom.
I tried with ISR, VSFilter and XySubFilter but subs are not showed in the black bars, but on top of video. How can i solve? As i can see (using xysubfilter), the subs are on top of video for a portion of time, then go in black bars, then returns on the video area... don't know why...

The HDMI RGB Range has 3 settings: Auto, Full, Normal. For some reason the TV means "Full" = 16-235 and "Normal" = 0-255. This is an inconsistency which I never really noticed since I always used "Auto", until recently that I started fiddling with NVIDIA's CP output and madVR's settings. The TV's "Normal" (0-255) will force a 3rd black crushing level when activated which is slightly more unnatural than the black crushing NVIDIA's CP / madVR does when set to their equivalent "0-255" - as if there is a loss in quality. Auto seems to almost always use "Full" (16-235) or Limited for everything else, and this is what it defaults to when receiving signal directly from the blu-ray disc or any signal in general, in all my tests it never switched to its 0-255 levels. This mode does nothing when YCbCr signal is sent. |

Hi guys. I noticed that in recent madvr versions image upscaling and doubling are now on the same page, most guides i checked was on older versions, so i am wondering which option should i choose.
I have a GTX 1070 and was using dxva2 on most options, very low render time but i read that i was losing some image quality. So which settings are considered the best to use on a good gpu? Also if i have a good gpu, is there a reason to not use dxva2 on image downscaling? Isn't downscaling only used when the window is not on fullscreen? Edit: I use a 1080p display. I also notice how little resources dxva2 uses. I put every possible setting on dxva2 and only chroma upscaling on nnedi 128 neurons gives me 0,3ms render time, gpu is almost at idle. I already tried some settings but it seems that it doesn't make much difference. I tried one that uses NGU and other settings enabled that put my 1070 to really work hard but not really sure if I saw any difference. I tried with 720p and 1080p sources, all with high bitrates.

If you want more 'pop' I think it'd better to sharpen with madVR (because it can be adapted to the content being played using profiles) rather than with the TV's Content/Sharpness settings. Quote:
(sorry but that's rare to see a Panasonic plasma owner say the THX mode looks like complete crap, it's the most accurate factory mode! ) Quote:
I think I know what's wrong here: as can be seen on the first screenshot of your TV settings, it's on Dynamic mode. That mode uses non-defeatable dynamic contrast which means you can never have any consistency in brightness levels as the TV will always try to artificially boost contrast by crushing blacks and/or clipping whites. So if you want consistent levels you need to use another mode than Dynamic, sorry. If you absolutely want Dynamic then you can forget about any accurate brightness levels setup. Your best chance is to manually copy all the settings values from Dynamic mode to the Custom one. This should give you a picture closest to it but without the dynamic contrast that messes up the brightness levels.

I would tend to agree. My custom settings aren't TOO far off the THX settings for my Panny plasma. It's definitely all subjective but I would venture something's not configured right somewhere if it's that far off.

It is fine if you want to keep using the other modes but do understand that they are much more inaccurate and have very blue white points (>8000K) when the standard is 6500K. This is why it looks yellowish to you, your perception of white adapts to blue=white so white=yellow to you until your perception of white adapts again.

Ive always used a little sharpening as I find I need some with BDs and DVDs upscaled to 4K on a 145" dia, scope screen. Enhance detail is what Ive been using for sometime. However Ive been recently experimenting with adaptive sharpening after reading the definitions, as I wasnt too happy when I saw that enhance detail also sharpens artefacts. A very tiny amount of Adaptive sharpening with NGU AA Very High, looks spectacular on my large screen with the JVC X9500. Below are the definitions: Enhance detail: [1.0] Sharpens textures like skin or cloth, also sharpens artifacts. AdaptiveSharpen: [0.5] Tries to sharpen medium sharp edges the most, it avoids sharpening near flat areas and very sharp edges Do any others use Adaptive Sharpen, or what are your thoughts? |

I'm a big fan of Adaptive Sharpen, use 0.5-1.0 on pretty much everything. |

On the TV they always look yellowish to me (and pretty much everyone else), and you never get used to it - maybe it is the model, but THX modes definitely do not look right under any circumstance, it seems as if RGB and whites are not properly calibrated, using "Normal" mode with less brightness and "Warm" colours looks very similar to THX modes, this does not seem right to me, even the colours look washed out in certain situations in comparison to plain old "Normal" mode. When we first bought the 2x 4k Samsungs we cross-referenced with the plasma and another 1080p LG for comparison. They lacked the THX modes (or we did not find them) and they looked absolutely fine on their Normal or Movie/Cinema modes. If I remember correctly, one of the Samsung's also defaults to "Warm" on its Cinema mode, but it is a calibrated Warm, not the same as switching to Warm on Normal mode which is what the THX mode looks like on the plasma. Now, I know the dynamic mode with "Normal" colour settings is far from correct, but its image is closer to the other TVs and the movies look closer to what we saw in the cinema - something far from true when we run Panasonic's THX modes. |
