Is there a guide or standard settings used for displaying HDR content on an SDR PC monitor? I've got a film to look pretty close to a 1080p SDR version by using:
- Convert HDR content to SDR using pixel shader math - Display's peak nits: 100 - (All other settings default) But it's still a bit washed out. I assume there's no "perfect" solution to this?

Hi,
Im testing the new DXVA11 native decoding with madvr and lav filters. I use Intel HD620 GPU, this is working. I used to use DXVA2 scaling for chroma and image bc this sufficed. With DXVA11 decoding the chroma and image scalers used are Bilinear. Is there a way i can get DXVA11 decoding with DXVA2 scaling? |

Refer to the release notes for the limitations: https://forum.doom9.org/showthread.p...91#post1815291 Hopefully madshi finds some time soon to resolve those limitations, so we can recommend D3D11 decoding without reservations.

Ok, so after matching refresh rate with movie rate by adding 23p and 24p to the string, i had time to watch few HDR movies like Lucy and Star Wars i noticed cpl issues :
1st im getting framed drops and repeated frames, which when i had refresh rate at 59hz never happened. 2nd thing now i have frame repeated every around 7.30min, when on 59hz i had around 44min. Clock deviation is on 0.00000% Didn't check yet any 1080p movies so can't tell if there will be same issues, so far only those 2 movies in HDR So my question is why after matching tv refresh rate to movie such problem started to occur? and steps i should i do to try make this sorted. btw. i have smooth option off if does matter or not in this situation, but from what i remember when i had on, there were issues with smooth playback what i notice as well that : - decoder, upload, render, present queue cant stabilize, i can see every few seconds changes there cheers Last edited by maxkolonko123; 30th March 2018 at 21:50. |

At 60Hz each refresh is less than half the frame time so you do not get repeated frames reported even if madVR needs to hold a frame for an extra refresh. The same with displaying a frame for one less refresh, every frame normally gets at least two refreshes so even if madVR needs to drop a refresh to resync the frame is still displayed, just for less time, so no dropped frames are reported.
With a matching refresh rate any need to resync the video to the audio will result in dropping or repeating entire frames. You need to use the custom refresh rate tab of madVR to optimize your refresh rate to match your audio clock. Do not pay attention to the clock deviation reported in the OSD to judge this, the reported dropped or repeated frames are more accurate indicators. Small fluctuations in the queues are normal, as long as none of them have a 0 it should be fine.

If you are using reclock and still getting dropped or repeated frames something is wrong somewhere.

Setting a very low 'peak nits' value will make the picture brighter and with more contrast but with lower dynamic range as highlights will be clipped (Edit: compressed) more severely. Do you know the real max brightness of your monitor in cd/mē (nits)? If yes then try setting the backlight of your monitor to its highest possible value (or better make a profile for madVR HDR if possible), and then set the 'peak nits' setting to your monitor's maximum light output value. Many PC LCD monitors can easily get to 300-350, which is blindingly bright for native SDR but useful for madVR's HDR downconversion.

Stop using Reclock and use smooth motion with 60Hz (disable display modes) or keep Reclock and use a matching refresh rate. Check your Reclock settings if you are getting reported dropped or repeated frames watching 23p at 23 Hz. Ignore the "1 frame repeat/drop every X minutes" in the OSD when using Reclock, Reclock messes up madVR's predictions because it is constantly adjusting the audio speed to prevent dropped or repeated frames (edit: except when the video frame rate is too far away from the refresh rate, like 23p at 60Hz, in which case it does not do its adjustment).

When you play at 59Hz, all is not good. You have judder and motion problems unless you use 'smooth motion' setting which helps.
If you have a native 60hz display, use that old setting with smooth motion on. If you have a native 120Hz display, use how we are trying to explain to you for best results. Is your display native 60Hz or 120Hz? Google 'refresh rate' for your model.

is there a way to enable upscaling refinements only when a certain level of upscaling has taken place? I like to have various enhancements enabled when upscaling SD DVD content to 1080, but when I watch stuff which is already in HD I get dropped frames unless I disable them, and I don't really need the enhancements enabled then anyway
I'm running MadVR on a HTPC so I don't really want to be fiddling with settings every time I watch something, ideally I want one setting that works all the time (which currently means I have to keep some of the enhancements disabled) also, is there a way to choose a basic upscaling algorithm other than Jinc when a doubling algorithm is selected? I have xbr selected for doubling, with Lanczos3 for "if any (more) scaling is required", but when I watch 4:3 1080 content with black bars zoomed 50%, it scales the image using Jinc AR regardless |

When i was using smooth motion with 59hz they i had really stuttering playback, that's why now is off. Do you think that my issue might cause of Display 23.97852hz composition 23.976hz Would this small difference matter? Reclock showing : refresh rate 24.000hz DDR, while in nvidia planel is 23hz insted 24 like it says in reclock, but dont know if this matter Last edited by maxkolonko123; 31st March 2018 at 00:26. |
