The only thing that seems to be fixing this is lowering my settings under scaling. I don't understand though, how could my previous settings work, but I have to lower them after updating windows and Nvidia drivers?
Edit: Fixed it. All the updates reset my overclocking. Last edited by toki; 28th May 2020 at 14:24. |

That would be this thread:
https://www.avsforum.com/forum/24-di...projector.html madshi hasn't checked in on doom9 in a very long time, but he does every once in a while at AVS.

quick question.....
is it normal for GPU´s to have coil whine when using MadVR? i had an gtx670 and had coile whine when using MadVR, and 2 days ago that Card died while watching a movie... Im pretty shure that MadVR DID NOT kill it, it just gave that old Card teh last push i guess... The Card had it coming :P Anyway.... i now got an GTX970 and its exactly the same thing^^ When using MadVR i have coil whine... the higher the RAM/GPU Clock, the higher the screetching sound... I did now mod my bios a bit and lowered the RAM just a little and the also the max TDP, now its still there but way better then before... Has anyone else experinced this? How DID YOU fix this? Is that common? And one more question to the advanced Techis here, is it bad for the Card? (i mean, i have at least one Card that died while "doing" it :P )... i mean i know what coil whine is and how it works, but im still wondering.... It could also be dirty energy? i forgot how its called, when the PSU isnt that good and gives a not so clean signal, wich the GPU / Hardware has to counter and then u can also have Coil whine.. is there a way to test if its my PSU? I know, i know, those are some more techy questions, but i hope you guys have still something to say Best Regards.. |

madVR is more likely to cause coil whine. It is a very spiky load, once the queues are full the GPU renders one frame and then idles until it needs to render the next frame. At a 70% load with 24 fps video this means the GPU is using a lot of power for 29 ms then very little power for 13 ms, and repeat forever.
But a GPU does not have to whine with madVR, my last two GPUs have not whined while running madVR but I did have a GPU that had a louder whine with madVR than it did normally. Whining is not dangerous for the GPU.

Yes.
You can´t really fix it. Some cards are affected, some not. It depends on the coils, their design and quality. No. It´s annoying, nothing more. Quote:
The current "quality" should be sufficient for all PC components and it should not have an impact on your GPU´s coil whine. The PSU itself can be affected of coil whine as well (independant of the described problem). So no need to test or change your PSU. |

That should be easy to determine, press mute on remote of AVR. If the whine sound is still there, it is coilwhine, right? Do you know what is causing this noise from speaker under load, I think there was something here in the past already, but I can't really remember.

Coil whine unfortunately can be ALOT of things rolled into one.
It could be a coil/ capacitor/ chock/ resistor/ inductor, etc etc, anything that creates friction(resistance) for electricity can exhibit the piezoelectric effect. Plugging in different components _TOGETHER_ often changes the situation of how the electricity drains through the device, so it can cause whine that wasn't there if those components were seperate. This is primarily why OPTICAL is still the cleanest option for PC sound output as it's a form of galvanic isolation. GPUs/CPUs are resistors, therefore, given the right circumstances, they screech as well.

Thank you for all the informative Answers.
@tp4tissue yes, i did recently change my Hardware.. (upgraded) @Asmodian Quote:
--- Also, i know what Coil WHine is and its coming form the GPU.. NOT the speakers. Like i sayd, when downclocking the Card, the Coil whine is allmost gone and cant be heard under 40cm... --- i know what you guys mean about the speakers. i checked them and they are all grounded and do not touch metal with metal, etc etc.. Its only when the GPU is used.. And Coil whine is still present when i unpluged my sound system completly. (also in Hardware Manager disabled).. I have another GTX980 here, but i need an 6 to 8 pin adapter first before i can Test this Card also.. If it does not have coil whine im gonna keep the GTX980 instead of teh GTX970 STRIX (wich from looking on the Webz, coil whine is kinda common, teh whoel 9series from what i was reading). @clsid Quote:
I allways thought that the NGU scaler would be one thing that is causing it, and shure enough, when i tested it, NGU did make more noise then Jinc, superXBR did.. So i also settled for SuperXBR for the moment and do not quadruple anymore, since this also caused more noise.. --- But yes, in teh End it looks like thats just the way it is and how a coil/ capacitor/ chock/ resistor/ inductor, etc etc. work... What i found out, at least for my GPU, is that lowering teh GPU RAM Speed did really help.. So i edited my GPU BIOS a bit, i do not need an OCed Card, so no Biggy for me.. Thanks for all teh Answers here, some good information..... Best Regards Last edited by BetA13; 31st May 2020 at 22:25. |

Color space metadata
Hello,
My display (Sony) calibration was set do "disabled display calibration". When looking HDR content with MADVR the display (Auto detect settings) correctly switched to Bt.2020 and HDR. But, I recently watched a video that is Bt.2020 non HDR. The Tv Color Space stayed at BT.709. I never noticed that my tv color space didn't switch automatically to the correct color space as 99% of my content is Bt.709. Is it normal that Madvr doesn't sent color space metadata unless HDR. Had to change my calibration to "diaplay is calibrated to BT.709". Doing so, MADVR translate the color space from BT.2020 to BT.709 loosing precious colors during the process but at least the display show accurate color. Could switch the tv manually to BT.2020 but nobody wants to do that, right? |

SDR does not have metadata, so there is nothing for madVR to send. You can keep your display in DCI-P3 and set madVR so it coverts BT.709.

Who know anything about future of madvr? Will tonemapping be fixed in future? I can't uncheck "compromise on tone & gamut mapping accuracy" to activate two disabled options in "hdr" section. With unchecked "compromise on tone & gamut mapping accuracy" picture is reddish and unrealistic (I can not imagine who like it).

And yes, I think most people would choose the second one. Last edited by Alexkral; 2nd June 2020 at 18:04. |
