With the same driver, I can't create custom resolutions, either with madVR or nVidia tool. It doesn't let me add custom resolution because it considers I already have a 23 & 24 resolution. If I delete 24 in my EDID, I can add a custom resolution, but only 23 and not 24 (since the 23 is considered a 24, old bug). So in case I had a 24fps video, I wouldn't be able to play it correctly. So I gave up and use nVidia new standard 23.976Hz (resulting in 1 frame repeat every 11-12 minutes). |

After reading you guys talking about the 23p situation on nvidia I tried to see if I could fix it on my end.
I'm on driver 398.36 and I'm using Horizontal: 1276 + 88 + 416 Vertical 8 + 10 + 60 pixel clock 301.58 mhz. In the OSD I get 23.97670hz but the composition rate changed to 23.978 instead of sticking to 23.976xx Also in the optimized timming parameters I get 1 frame repeate every 4:40 minutes and it seems it doesn't matter that timing or pixel clock I choose. Every time I change the current timing it shows the same 4:40 minutes, even if I use one of the optimized pixel clock that show no frame drops/repeats after a reboot it shows 1 frame repate every 4:40 minutes. Also, I'm trying full screen exclusive now and while in FSE I get composition rate 60hz? Is that a bug or something? The display is at 23.976 Last edited by veggav; 26th July 2018 at 20:17. |

Can someone please explain what the composition rate is and why it is different from the osd refresh rate. (I asked this question earlier in this thread but I think my question got lost in a couple of other questions I had in the same post.) Cheers, Peter Sent from my SM-N950F using Tapatalk |

The composition rate is the Desktop Window Manager which controls when screen updates actually happen. It is pretty good in Windows 10 (though Windows 8.1 is the best one according to madshi), and it is required for proper playback.

Last year I reported a bug, never got any feedback, but then it was fixed in the next driver branch. No idea if it was luck or if me reporting it helped.

Is the composition rate anything to take into account when trying to set custom refresh rate or is it what it is. Is the Composition rate something that can and should be changed. For me I have different refresh rates showing in Nvidia, Win 10 composition rate and in Vertex. Again, thank you for sharing. This is s very interesting topic. Sent from my SM-N950F using Tapatalk |

I would not worry about small differences in the composition rate, but it will cause trouble if the composition rate is 60 Hz while the refresh rate is 23.976 Hz or drastic mismatches like that. The composition rate should be close to the refresh rate, e.g. Windows 10 will set it to 24.000 Hz for a 24 Hz refresh rate or 23.977 Hz for a 23.976 Hz refresh rate.

My composition rate is set to 23.978 which sounds about right for me. Sent from my SM-N950F using Tapatalk |

No, but your GPU has to support 10 bit and enough bandwidth for the resolution and refresh rate. HDR does not enter into it.

Only via some motion interpolation (in which case just use your TV, apparently Sony is the best in this area) I did suggest the idea of sharpening only the blended frames some years back to madshi to combat this, but I guess it wasn't that great an idea.

I have W10 build 17134 with i7-7700 integrated Intel HD630 on a Asrock mini-itx.
I also did a 3d-LUT with displayCal with MadVR. I get random crashes with BlueScreen (first screen freezes, then becomes black, then audio get crazy, then BOD) when playing video with madVR enabled, using MPC-HC or Potplayer. When I disable madVR, i.e. with EVR all is fine. BOD Error VIDEO_SCHEDULER_INTERNAL_ERROR Can pass also 10 days with no crash, but sooner or later... Generally I get the crash when scrolling the wheel to jump forward or backward. What can I do to solve this? |
