Agreed on dialling back the chroma.
But just having a play this morning, and if I do set chroma to bilinear, and enable the HDR options in trade for performance, I get a slideshow in either D3D11 Fullscreen Exclusive or Fullscreen windowed and D3D9. But if I come out of fullscreen exclusive or fullscreen windowed to just windowed it drops from the hundreds down to 21 ms ish ? Does this make sense ?, should going from windowed to fullscreen exclusive or fullscreen windowed make that big a difference ? I am using nVidia drivers 416.34. |

New 2070s are cheaper then new 1080s here, nevermind 1080 Tis (in which case 2080s are also cheaper).

Just for clarification guys, and maybe to stop me pulling any more hair out.
If I use HDR tone mapping but have to select all the Trade for performance options to on, is this still better than allowing HDR passtrough ? |

https://www.philips.co.uk/c-p/65PUS6...ilight-3-sided I did think I would be limited with chroma, but was a little naive about how much the tone mapping would hammer my 1050 GTX, it was a case of I could get better chroma settings and use passthrough, but was unsure what I would achieve by disabling the trade options comparable to passthrough, as it classed it as dumb on the OSD when you do this with the options ticked, and that used to be options in older madVRs. |

Network latency could also be an issue if the queues suddenly drop when playing certain files. Check to see if the video bitrate is higher with these files.

Pixel shaders might be a bad idea with the limited amount of VRAM you have.

All valid points in the last two replys.
I guess I may just bite the bullet and go for passthrough as to be quite honest I don't even know what to look for, have no idea what my peak nits would actually be. I think now I actually have a 4K TV now, the miriad of options for setting up HDR settings/contrast and colour, unlike setting up to maybe get a comparable ISF setting by reading reviews, there is very little on what HDR should actually look like. I have been following your now updated guide which is very informative, the hard part is a lot of it boils down to what we like to see on our screens, and HDR/4K is still so new to me I do not know what is actually good or bad, I have long since stopped understanding the BETA builds and the testing of madVR for HDR, and maybe I just need to let it go and go passthrough as stated before. |

Hi Madshi,
thank you for your great program, it really improves the video quality on my 1080p display compared to other pc video players, or when using a stand alone bluray player (assuming the source video file is of good quality) Q1) is there a way i can set my display max nits in madvr ? i am using madvr on my win 8.1 pc to play some 4k hevc h265 rec2020 video files, which i output over hdmi to my 1080 display (which is accepting 1080p 12 bit 4.4.4 RGB full) . in madvr settings i am using DXVA2 for down-scaling wich gives me a gpu load of 72% and uses 90% of my 3gb vram (the other custom pixel shader settings like SSIM cause a significant rate of frames being dropped and i get micro stutters) some of the 4k video files are HDR (which i know is not part of the SDR specs), but my 1080 tv display has a spec of 380 nits (compared to most older 1080 displays only going up to 150 nits usually) i know that some of the higher end stand alone 4k bluray players (like the samsung or panasonic) allow you to select a max nits setting when outputting the 4k HDR video to 1080 (for ex on the samsung player i would have been able to set it to 350 or 400 nits iirc) can i similarly set a max nits setting in madvr for my 1080p downconversion output ? (i remember discussion about this taking place in the madvr forum, but cant find the settings) note: i am aware most HDR movies can range from 500 to 1000 nits (or even higher w dolby vision ?), but my display relatively low 350 nits ability would be nice to be able to use for higher luminance detail available from some of these HDR source files Q2) is there a simple way i can save my preferred presets for different resolution video files that i might be playing ? (eg 720p, 1080p, 2160 4k files etc) - for my pc hardware i can use higher quality settings for 720p and 1080p files, but for 4k files i can only just play them and have to dial several settings down Q3) when playing 4k files (with my limited settings ) my GPU reports 72 or 75% GPU load, and 93 % vram used for ex, but my i7 cpu is only at 20 or 25% load. - is there a way i can offload some of the video tasks more to the CPU and then be able to enhance other settings in madvr that are GPU load dependent ? i have tried different "video decoder" selections in mpc-hc, but it doesnt seem to alter this (am using dxva2-copyback as this was suggested by you in an earlier setup guide iirc) pc specs: win 8.1 (64 bit) w most recent video drivers and updates, i7 4770k, 32 gb ram, 1060 3gb GPU using mpc-hc 6.3 with madvr latest version |

One more thing and I am unsure if there is an issue with madVR and my TV. The one easy thing I seem to have is NV HDR is ativated quite easily, which is a blessing on having read back over multiple threads on it not for some people due to drivers et al. But if I select the OSD for the TV once activated, sometimes it says BT 2020 and SMTPE 2084, but mostly only if I change a setting in the settings side of the TV. The majority of the time it will say RGB for colour space and 2160p24, but sometimes it will say 2160p24SMTPE 2084 for video and BT.2020 for colour space. it looks to be getting the right information from looking at the madVR OSD, so is this an issue with my TV not being very clever and I can just ignore it, or do I need to mess with drivers to get this correct information. |

Have a look at this guide for the presets, under profiles. Also the target peak nits under HDR, but would assume you have seen this ? Last edited by madjock; 7th January 2019 at 16:49. |
