Coil whine is very frustrating because it usually only shows up with very specific loads. I have even seen (heard) power supply based coil whine that changed pitch when scrolling the mouse wheel. People sometimes get some 2-ton epoxy or similar and try to lock down/dampen the chokes enough that they stop whining... with mixed results. Manufactures rarely accept coil whine as a reason to RMA unless it is really bad, and even then they are sometimes difficult.

OK I tracked it down to the option to reduce compression artifacts. I can change anything else, turn stuff on, but once that 1 setting is off, the noise stops. So is this a real defect in my sound card or just that this 1 option pushes the card past its intended limits?
Also, I might as well ask. I've been using JINC with reduced ringing artifacts. There's other options like the multiple NGU options, DXVA2, Super-xbr, and I believe in the player I can pick CUDA since I have a GTX 1070. Which options should I use, and if I should use one that has other options like doubling, quadrupling, etc, what settings would be best for my system? Thanks |

Well when I changed the "reduce compression artifacts" from High to Medium the pitch of the whine changed.

It's annoying and I have it too with my 1060. Try using DX11 decoder in lavfilters and dropping NGU quality to high. Should make a big difference. I also stopped using RCA since it helps a bit. I very much doubt you can return the card, but you're welcome to try.

Hey all, I'm having a torrid time trying to get custom resolutions working on my system
I feel like I've tried everything but I always seem to get a frame drop every 4 and a bit minutes. Is this currently just not possible with the latest Nvidia drivers? I'm almost ready to give up getting this to work as it's becoming so frustrating |

It isn't quite not possible, at least for one refresh rate, but it is not easy.
I have had a lot of trouble getting Nvidia to actually USE the custom refresh rate with the new drivers... I found that deleting everything out of Nvidia's custom resolutions, effectively disabling that feature in the drivers, and then letting madVR do everything including adding and changing to the custom resolution worked better for me. Giving up and using smooth motion... is not totally crazy.

Coil whine usually occurs with a specific combination of graphic card & PSU as in another PSU might not trigger the whine at all FWIR.
The funny thing with mVR is that upscales made by HDTV channels look totally facepalmic in comparison but then again I know a guy who does encodes for netflix and he's using the same crappy profile for everything in single pass so I guess HDTV technicians don't care any more than he does. |

Finally got to bottom of it on my setup - just sharing as it may help others with an Nvidia card and a Samsung SUHD set (using HDR+ and colour space to Native to scale up and out into BT.2020 for SDR content, and HDR+ and colour space Auto for HDR content) If I set Madvr to full, I have to set Nvidia to 4.4.4 limited and the Samsung to limited to get anywhere close to correct colours, clipping levels and image noise (for both SDR and HDR). However, the best set up here now (after many hours of testing back and forwards) is Madvr = Limited TV Levels GPU = Full RGB, 36bit for 23hz etc, and content type set to full screen videos Samsung TV = Limited/Low This may, or may not help others with a similar set up to mine.

I'm just very surprised that TV channels still use the crappiest upscaling ever but then again HDtracks & Qobuz do sell some obvious 16/44.1 upsamples to 24/96 for a Premium and not many people complain due to not knowning the 16/44.1 counterparts : http://www.itrax.com/Pages/ArticleDetails.php?aID=32
My point was that mVR keeps evolving and gap becomes larger and larger. |

When using Windows 10 Spring update 1803, Latest GeForce 397.31 and latest madVR v0.92.14.
Nvidia HDR full screen windowed mode is 8bit only. Doesn't matter if starting from Nvidia RGB Full, 422 10-bit, 420 12-bit or default colour settings. In fullscreen exclusive mode 10-bit is working starting from Nvidia RGB full using NV HDR. It's now possible to enable Windows HDR/WCG toggle from display settings when using Nvidia RGB full but this is reported in advanced display settings as RGB 8-bit with dithering and HDR. When changing colour settings from Nvidia RGB to default. Movies still start in 8-bit with dithering even using OS HDR. Setting Nvidia 422 10-bit and OS HDR has working full screen windowed 10-bit but full screen exclusive mode doesn't work. So at the moment I can use RGB Full Nvidia HDR and full screen exclusive and it seems functional but not as easy as before. Last edited by Sideeffect; 28th April 2018 at 20:42. |

Now that reduce artifacts runs for free with lots of flexibility, are there any plans now to allow different strengths of RCA between luma and chroma? I've generally found that luma channels usually look pretty good, but chroma channels can look like trash on medium quality HD encodes. High values of RCA on chroma only might be able to give a similar effect to bilateral or reconstruction. Would there also be plans to allow RCA to run for free on NGU Standard and Soft?

What madVR settings should be used to effectively utilize the 500 nits of brightness on the 2017 iMac's display when playing HDR content? And is video on the iMac 10bit or 8bit?

What's that please? I figured I might as well downscale them before feeding them to mVR somehow.
As much as deringer is set-and-forget and works on anything IME, RCA Medium @1 really destroys PQ on very grainy BD movies Last edited by leeperry; 28th April 2018 at 23:38. |

I am impressed by how well remove random noise works on grainy content, but of course it does smooth some.

debilinear is a downscale filter to create the "orginal" pixel of a image upscaled by bilinear.
there are more than debilinear and you need to select the correct scaling algo and you need to find the original image size to make best use of it. |
