For most purposes you don't need "perfect", you just need "good enough", which even for long movies is probably like ~3 hours.

That's something that has to be improved, especially 3D (although I'm aware that 1) this is primarily nVidia's fault and 2) that's not going to be easy/possible in 3D).

Even without madshi's tool to make custom refresh rates easier, I've been setting up custom rates with only NVIDIAs control panel for years with 2+ hours of drop time. Its really not that hard.

my acceptance criteria for the safe side is above 10 hours before the first drop/repeat occures and i do not care about smoothing problem. In this condition, enabling Smooth Motion function does not give any added value. The last (small) flickerings that are still existing (especialy on vertical travelings) cannot be removed by SM but only by the smooth feature of the TVs or Projectors if there are equiped with.

If the scan with custom modes function does not give you the expected good timing (or blank screen) , then, a simple calculation based on the displayed data "1 frame drop/repeat every :..." helps to manually calculate the good settings for back porch H/V and pixel clock This is what i do since custom mode scanning does not always give me a good result. With ATI graphic display board, no issue with the driver. Last edited by Polopretress; 30th May 2018 at 14:39. |

But phrase "we have [tens of] minutes exact video and only few seconds changed" sounds as good as with hours Some people are very sensitive to repeats/drops. This thread is good example. That's why this discussion take place. P.S. "as high as possible" is the madVR slogan, isn't it? |

Well if you have a 3-4 hour drop interval, you're not going to see any drops unless you actually watch a movie that long. So in this case while higher is of course "better", it doesn't really benefit you either.

@madshi
Is there a way in MadVR to force resolution to switch from 4k/24 to 1080p/60 when 3D mkv is played? Right now madVR upscales all videos to 4k/24, which is what my desktop is set at and because of that 3D does not work. |

Hey guy, we were not talking about the fact of a drop/repeat frame that can be seen but the impact of this settings on the smoothness of the video (and the need or not to use Smooth Motion function)
Of course 40min of drop/repeat is not really an issue to lose or repeat a frame but the impact on the fluidity of the video is more visible when timing is not "perfectly" or "near perfectly" set Last edited by Polopretress; 30th May 2018 at 14:49. |

Unfortunately that's not the case for many of us, especially with projectors. I do agree though that if I could get 3+ hours in both 2D and 3D then I wouldn't be looking for anything more. 50-60mn in 2D is close enough, if the shot is mostly static when the 2-3 frame drops happen I won't notice them. 3-5mn in 3D sucks and makes it close to useless to those of us sensitive to frame drops though, and there doesn't seem to be a way to improve this, sadly.

Yea, the drops in 3D on nVidia is very noticeable. If there's a way to improve that, I'd be all over it. Lately I can't even get a 2D custom res to work all that well for my panasonic plasma. sigh.

Does someone here knows the root cause ? If you have also problem with 2D , it is probably because even if you modify and create a custom resolution for your Pana, it does not take into account and keep using his EDID settings to display. In this case, 2 solutions : 1. modifiy the EDID instead of creating custom resolutions 2. create a multiple of your frequency but apply the settings of the real frequency.(and , of course, modify this setting in madVR by replacing for example 1080p23 by 1080p47) in that case, you "turn-around" the system lock. On my Pana plasma , i apply the second solution because i prefer to avoid to modify the EDID file. Quote:
I have already spent hours and hours with one JVC of my friend to try to make it accept a new setting without blanck screen.... Sony and Epson are really more flexible ! Last edited by Polopretress; 30th May 2018 at 16:01. |

There is only one custom refresh rate setting that works with the JVCs (at least mine) with my 1080Ti and it's the EDID/CTA. That's the one that gives me 50-60mn between drops in 4K24 (2D). There is no need to "train" MadVR for 30mn, just select it and apply it. I haven't tested any other res/refresh rate as I don't really care.

Thanks to my great Nvidia driver contact, I managed to get a fix for 1080p23 timings into newer driver versions. So stock 1080p23 timings should be much better now with newer drivers, probably also for 3D. I know, the newest drivers come with their own problems, so many are still using older driver versions. But JFYI... |

I hope they'll solve the levels issue at the same time, that's the main problem with the latest drivers. And good luck with your commercial work
