Not much else to it, we've been doing it this way for years with madVR and MediaCenter, not sure what an "installer" is going to do any differently. Why does the "installer" have access to the machine, but you apparently don't?

I have learnt all the settings in madvr which he doesn't know as well as I, its just the install stuff/updates I need him for. |

However, I still have a concern. I was using the Calibration Tester not to reset the LUT but to check the status of the LUT. I did this testing on three systems with different GPUs – Intel, AMD and Nvidia. In all three systems there was no ICC profile used and there was no application manipulating the LUT. In this condition, the default state of the LUT was found different than it was when madVR reset the LUT (through “disable GPU gamma ramps”) as you would have seen in the Comparison that I posted. So by default the LUT is set as slightly non-linear. Yesterday I also observed that if in Nvidia control panel -> Adjust Desktop Color Settings -> “Use NVIDIA Settings” is selected, the state of the LUT changes to linear from the default slightly non-linear state. Similarly, if in AMD settings -> Desktop Color -> “Reactivate AMD Color Controls” is selected (with default gamma 1.00), the state of the LUT changes to linear from slightly non-linear. I was wondering if there is any implication of this slightly non-linear state of the LUT? Could it be that the GPU driver doesn’t do any processing of the LUT when it is set in this slightly non-linear state (the default OS state)? |

Incidentally, while writing my own little program to keep my LUT loaded (a lot of games disable it when they go fullscreen), I saw a lot of problems on an Intel GPU. The LUT would get reset by various events (by Windows security dialogues and the like), but the GPU would be convinced that the old LUT was still loaded - and loading it again would do nothing. I eventually solved this by setting the LUT unconditionally, and quickly switching back and forth between two imperceptibly different LUTs (the actual LUT, and the same LUT with all 16-bit values increased by 1) once every few seconds. Thankfully doing so didn't seem to cause video playback glitches, but having the GPU just flat-out lie to you is pretty annoying. Quote:

Many thanks aufkrawall and Asmodian for explaining the downscaling light options! Indeed, I got it wrong so now I have linear light enabled only with UHD -> 1080p scaling (I've shot a lot of UHD stuff on my Samsung Note 4). I always use SuperRes along with doubling though, so best to settle for gamma light for the other profiles then.
BTW, speaking of Samsung Note 4 and its variable frame rate clips: am I dreaming, or can LAV filters affect how smoothly VFR vids are handled in madVR? It feels as if dropped/repeated frames seem less jarring/glitchy as of late. It seems to me this happened after updating my Kodi DSPlayer which had the most up-to-date LAV package (the player itself is no longer being developed). I would think a dropped frame is a dropped frame though, so maybe I've just grown accustomed to VFR's inherent glitchiness, dunno... Last edited by Uoppi; 12th May 2016 at 14:21. |

If you're using SetDeviceGammaRamp, this may not be enough for fullscreen (D3D) games, because the APIs allow for different video card gamma tables in desktop/windowed mode and fullscreen (exclusive) mode where the latter can only be influenced from within the actual game process (or via DLL injection, there's a small utility called ColorClutch which uses this method). |

I do not watch any anime, so I assume enabling both - 1. the new De-Ringing + 2. Reducing Dark Halo's improves image quality in films. What causes that ringing to begin-with? Does it affect specific Scaling Algorithm methods, like NNEDI3, Jinc, etc. ? Before this new De-Ringing, there already were Anti-Ringing features. Did these original features fail at removing ringing and dark halos? |

I just came across this link about bypassing the LUT for 10 bit output from AMD GPU on Linux. Below is a quote from there:
“The hardware lut's only have 256 slots for indexing by a 8 bpc framebuffer. In 10 bpc scanout modes, framebuffer color values would get truncated to their 8 msb's, thereby losing the extra precision afforded by a 10 bpc framebuffer. To retain full precision, bypass the hw lut in 10 bpc scanout mode.” I do use 10 bit output in madVR on my AMD system, and reading this made me shiver.

I like linear light downscaling because it preserves small bright details, like stars in a night sky, much better. After doubling all these small bright details are twice as big so linear light downscaling does not preserve their appearance any better but it does have more ringing and aliasing.

Slightly off topic (and perhaps me being a bit thick) - Anyone use a 1440p monitor here?
I had a 4K monitor at the backend of 2015 (27" Acer S277HK), but the grainy/hazy screen did my head in, and quite frankly I couldn't even see much difference when a high quality 1080 vid was played next to a high quality 4K vid, so I passed it on. I have read 1440 is a bad screen size for watching films/tv shows/streaming as it doesn't have a 1:1 scale like 4K would from 1080, only that it benefits games. Have a 980ti so I have the graphical grunt for MadVR but just wondering whether it's worth moving up screen size from a 23" 1080p monitor to a 25"/27" 1440p one. I'm presuming there are no adverse affect with MadVR too (besides being able to use less settings at the higher res)? |

Using madVR to watch 1080p on a 27" 1440p monitor is excellent. Image quality is better than 1080p on a 27" 1080p monitor because at 1080p the pixels are too visible and madVR's upscaling is very good. A 980Ti has enough power to run quite high settings even when upscaling to 1080p to 1440. (e.g. NNEDI3 64 luma doubling is easy)

You could probably try removing dark haloing for anime if your sources are high enough resolution. I feel like the halo detection is per pixel, which means that any dark lines won't get confused as long as they're sufficiently thick in pixel count. I tried it for clean 720p cartoon encodes, and it doesn't do any damage at the very least (or benefit much either, because they're so clean to start with) |

BTW, is there any easy way to play retail encrypted .m2ts files with mVR & Reclock? Can't really waste 40GB per movie remuxing them.

1080p with ringing is a total waste when you can get such natural looking deringing in realtime, who needs 4K no more Turns out it seems to work stunningly well with SuperRes LL@2 + AB@100 so please don't remove AB from SR anytime soon, still playing around but I certainly like what I see in combination with vanilla 100% LL SSIM2D & vanilla sxbr(whose main problem was amplifying existing ringing as I understand it). Outrageous results really, hats off |

What percentage of video content includes source ringing? Is this more or less common than banding with 8-bit sources?
