In calibration section, I set colorspace to BT.2020 and select "report BT.2020 to display. MadVR should remap BT.709 HD bluray to BT.2020 , and the switch should put the PJ into BT.2020 mode automatically. With HDR content, if set to "tone map HDR", the passthorugh of BT2020 should also be automatic. |

thx for pointing to the poor "presentation time" as an indication of my poor video play, i can monitor that variable also now when searching for solutions when i switch users on my win 7 install to admin user and play the same video files everything seems to run fine (using default mpc-ht and default madvr settings) see image https://ibb.co/fFq7m9 this would at least suggest there is no hardware issues (ram etc ) or bios setup problems etc, also the current win7 install works ok when run from another user account to. anybody know what else i can look at to find the cause of my high frame drops and poor render times? (as seen here https://ibb.co/eQ0VZU) to me the current poor video play seems to behave as if some crumbs from a previous madvr installation might still be interfering somehow with my fresh madvr and mpc-ht re-install and their default setup Last edited by zapatista; 13th October 2018 at 17:33. |

It's definitely DirectCompute related. Edit: it's fixed in madVRhdrMeasure10, just wait for the new release. (Although my laptop doesn't have enough juice to use both "compromise tone & gamut mapping ..." unchecked and "highlight recovery" at the same time )

have you set your panel to 10 bit or higher in MADVR?
In devices / properties at the top.

Khaled, use FSE Full Screen Exclusive.

Khaled, if you have anything open like right-click mouse and menu, it will be 8-bit until that menu is closed. If nothing is open, and it's still 8-bit, try rebooting. If you still have issues, try reinstalling the video drivers.

sending bt 2020 to a screen that is not bt 2020 is not ideal in my book. the screen needs to do heavy processing. this is totally different if you run a screen in native mode and 3D LUT correct the image. on projector it's an even bigger problem. |

Also, someone told me that the TV is better at scaling these resolutions to 4K, than Madvr, which is not the case, right? |

So I spent some time testing the dynamic tone mapping on my LG B7 OLED and the latest pixel shaders for HDR in the test version 9 (with saturation boost +15, peak 750 nits, output in HDR, and measure peak). Overall, both the dynamic tone mapping and the pixel shader attempt to do the same thing, except for one key difference. The dynamic tone mapping appears to affect the whole image, while the shaders mostly impact only the highlights or sources of peak brightness. I'm not sure if this is the way it's supposed to work, but it's what I see. This is even more effective where working with a 4000 nit master, which the dynamic tone mapping helps with, but no where near as accurately as the shaders. An example of this is the bright green spear cut that is one of the test shots. For 1000 nit masters, the impact on the highlights between the two is very similar. I did see some instances of color tone changes with the shaders, but again I can't tell what was supposed to be correct in the image. Regardless, either would look normal if you didn't switch between passthough and shaders. I've only tested a few movies, but so far this is very promising and enough for now to try using the HDR pixel shaders for general usage.

If you're using a dedicated gpu then that can matter for file decoding performance but not for madVR but it can depend on age and core count.
I used a gtx 960 for a good long time and it did well. I'd recommend anything similar or greater performance to get the most out of MadVR. There are good quality scalers used today on the latest 4k tvs but nothing that can match madVR's NGU in real time built in to any consumer display or readily available device. |

It really helps with shadow detail in dark scenes. Often times madVR is simply too dark compared to LG with active HDR turned on. You can use madVR for tone mapping and still turn on LG active HDR, but then you've got kind of a double tonemapping situation where the tv is trying to dynamically adjust brightness and highlights after madVR has already tone mapped. It doesn't quite look right IMO. Often times it will just make the highlights even darker. |

Switching HDR through Windows Display settings results here in madVR too dark black clipping. Since NV 416.34 madVR is able to switch HDR by himself again (Windows>Display settings>HDR off) - black/white clipping ok now.
