because the OSD is a powerful tool.
first of all deinterlancing is on but not used. why i don't know. so i have to ask more things. what GPU and driver is used. the next odd thing is the input file it is just NV12. is ffdshow or something like this min the filter list? a copy of the filter list may help. a sample would help but i guess this is a totally normal DVB mpeg2 or h264 PAL stream right? @AbbeKoenig a blind guess from me try to disable g-sync if active. |

Roger, but I thought as per https://forum.doom9.org/showthread.p...16#post1271416 , madVR doesn't use G-Sync?

I just realized that deinterlacing does work at startup, but only as long as I don't switch to another channel. |

I experience this problem with my TV when the data rate is too high for the cable. This is why AMD added a cable check in their latest drivers. A good cable solves the problem, or stay within the bandwidth of the cable. I had same issue with my Pioneer DVD player in the past. A new cable fixed the problem. The problem starts over again with 4K via older HDMI cables. Anyway, I have no issues with my XFX RX 480.

the cable check is uesless i even talk to AMD and ask them why this check doesn't do anything and they didn't even know what this thing does. depending on the driver used you will never get the image back until you unplug it. there is something big broken. and most important why doesn't this happen with nvidia. is there signal better so it works on older cables constantly? i'm through 5 cables and a PS4 pro sending the same type of signal using an AMD GPU with no issues.

you should be able to force deinterlancing with control+shift+alt+d better than nothing i guess. defaults should be fine. Last edited by huhn; 11th June 2017 at 12:16. |

I'd like to revive the conversation about the noise NGU generates in GPU, at least in my 1060. This weird ticking/clicking noise? I'm not complaining or hoping for a software fix, but as a phenomenon it feels very curious. I thought it was just a power issue, but running NNEDI256 doesn't cause that sound. Did we ever find a reasonable explanation? At NGU high the sound is basically inaudible and I'll just bump up other madvr goodies to compensate But still, it's facinating.

I use 1080p, 10 bits, 4:2:0, 60hz on a 12 meters cable between AMD RX 480 and Marantz receiver. This works fine. Higher bit rate causes glitches and screen goes black for seconds. True, the check does not improve the signal. It is added to tell you if the cable is not ok. This seems not to work. HDMI uses power steering at peers end of the cable. HDMI is sensitive to the HDMI implementation of the devices. It may happen that there is a mismatch between the devices and cable. A solution is to use a HDMI repeater. (HDMI 2.1 is bases on repeaters for long distances) Beside a good cable, check updates of the TV. My new samsung KS7000 got an update to improve HDMI connection with some UHD players. |

Hi guys,
is there any boolean value to apply a specific "profile" to hdr content with "undefined hdr"? I created a profile with the boolean value "HDR". Problem is, I have some videos which doe have HDR but somehow with hdr flag resulting in this "HDR: undefined" instead of HDR: 4000 nits for example. And in this case the HDR boolean value does not recognize the profile as being HDR. @madshi: would it be possible to extend the HDR boolean value to hdr undefined? @all: could I maybe filter with with a bollean value like "REC2020"? Or maybe H265? Thank you! |

and BTW. 1080p 4:2:0 is not part of the HDMI spec. 2160p60 4:4:4 is fine with my nvidia cards. |

The limit is 2160p30 4:2:0 on 12 meter. 30 Hz ís a too low frequency for Windows on the TV. With 2 meter cable 2160p60 4:4:4 works fine. Perhaps I should try a HDMI repeater and see if I can get more out of the 12 meter cable.

Hi I have been trying to get HDR working on my tv but with no luck. I use the passthrough option with both nvidia and win10 api, and neither one managed to send hdr signal to my tv, I suppose it's because the metadata was not sent, what could be the reason? I am using a dell inspiron 15 7000 series 7559. Also, not sure if it's related but I never got the hdr switch on the display page after the win 10 anniversary update

a 12 meter high speed cable has to be able to do the same as a 2 meter high speed cable or it is not high speed. no need to discuss this in the madVR thread. |
