I went with NGU AA medium/High depending on what profile activated.
Super Res is is an image enhancement algorithm which does the following. Calculate an initial guess (using a different upscaler) Downscale and calculate differences with original image. Scale those differences to the final size Improve guess by: Softening the image Subtracting differences with the original image Sharpening (optional) Removing aliasing (optional) Removing ringing (optional) Repeat steps 2-4 several times. Judge for yourself if you like the results, I've never felt I've required it, especially for chroma. |

Since we are here, can I ask you guys what settings (luma, chroma, enhancement, etc) you use to double 1080p / 720p content? Thanks

Please do your research into chroma before saying it's "not good" the standard and AA variants of NGU are known to be the best chroma upscalers along side Jinc and a few others. Your preference may be sharp scalers.. Personally I prefer natural results.

There are dozens of drivers that "work." Avoid any that don't work for your needs.

Does a 1070 help with that ?

Do have all of the trade quality for performance options related to tone mapping unchecked and highlight recovery strength enabled? If yes, then the GTX 1060 can still do the job (I would guess barely). If not, a GTX 1070 or better would help.

I need help evolving from 'poking at settings' to 'knows what poking at settings does'
Been using MadVR for a while now for HDR>SDR tone mapping on my Projector and I'm wondering if I am missing out on picture quality because I don't understand the settings properly. Windows 10 - 64-bit i7 - 16gb ram - NVIDIA 1070ti madVR v0.92.17 LAV - 0.70.2.81-git - My Calibrated Screen/PJ combo is hitting approx 70 nits with a rec.709.3dlut for Gamma 2.2 and I have this chosen in the calibration section of MadVR. I don't have any other 3DLut files generated. - For HDR>SDR I am using shaders with a target peak of 200 nits, BT.2390 curve, balanced color tweaks and high highlight recovery. I have 'measure each frame's peak luminance' checked but not sure if it works with NVIDIA CUVID decoding. I wondering about how much I 'dont know' and if I'm getting less than stellar results with this config. I 'think' my picture looks good, but without having any other point of reference I feel a bit in the dark. - For my 4k HDR BT2020 content, should I be using a different LUT? - Should I have Gamma processing enabled? - How do I know if I am crushing blacks or if my highlights are right? - How do I enable dynamic peak luminance adjustments? - Why does my cat drink out of the toilet not her water bowl? So many questions. Last edited by griffind; 23rd January 2019 at 23:22. |

Hello,
I've installed MadVR (latest version) and this is my system : HP Pavilion 300-030NB Windows 10 - 64-bit i3 - 4gb ram - intel HD 4400 graphics Latest mediaportal Latest LAV codec - set to dvxa2 copy back Connected to my Samsung UEJS9000 tv ( maximum refresh rate 30hz ( according to the "windows settings page" ) I had setup MadVR, according to what different users of an intel HD graphics 4000 (I have 4400) said, which was to use dvxa2 settings and such. But nothing seemed to prevent my video from not playing smooth/stuttering. I've tried numerous settings and different codecs ( Lav, CoreAvc Pro ), but nothing seemed to give me smooth playback. Until I tried the setting under "Devices - Generic PnP Monitor - display modes" "list all display modes madVR may switch to" The default setting had nothing in it, so I've now set it to "1080p23" and it worked. When I try to use 2160p23, it gives a black screen with audio only ( Lav codec - dvxa2 copy-back ) I guess the 2160p23 gives the same result as when you leave the field blank. So I'll use 1080p23 for now. But that leaves me thinking, now when a video is played, it will play in 1080p on a 2160p screen. So now it's not upscaling anything, right ? So is there any difference in quality now with this setting to "1080p23" between MadVR and the EVR renderer option in mediaportal settings ? I also had almost everything checked on the settings page of "Trade quality for performance". I'm going to uncheck one at a time now and see if quality can improve without performance. Is there any way to upscale my 1080p video's to 4k resolution with this intel 4400 HD Graphics and have smooth video playback? Or am I stuck with the 1080p23 setting for now ? Thanks in advance. Greetings, Soxbrother |

You will have to turn off many of the madvr's features in order to scale 1920x1080 into 3840x2160. Madvr will still give you more color accuracy, but to use higher quality filters like Lanczos, there's simply not enough processing power to do it. If you scale 1080p to 1080p, then that is chroma scaling only, 1:1 luma. the 4400 will do this perfectly fine. You can enable Jinc or Lanczos for chroma. I believe you also need displayport to hdmi 2.0 adapter, because 4400's native hdmi is probably not HDMI 2.0, which is required for 3840x2160 60hz Also, run CPU decode on Lav, do not use dxva, because you want to save as much GPU time as possible for Madvr. Letting the CPU decode the first part is fine.

Check the "measure each frame's peak luminance" box in the hdr settings page. I would also recommend not using CUDA acceleration anymore, DXVA2 copy-back or D3D11 copy-back is just as good or better and as universal solutions they are getting more development.

So... if there are large patches of very bright data, using highlight recovery, this can cause clipping right ?
I noticed some clipping on the helmets in film -interstellar- and near the end black hole escape scene.

This is not how GPU hardware acceleration works: it's a completely separate pipeline. Just use GPU hardware acceleration all the time if you can.

Hi guys,
I'm thinking about replacing my gtx1080 with a Rtx2070 which could be quite affordable money wise. The reason is I use my gpu almost to the limit with all the hdr new stuff and with the "reduce random noise" filter which I enjoy a lot, but uses lots of resources. Would it be a smart move or better get a gtx1080TI? Regards! |
