Does anyone know what kind of scaling can be done by a GTX 1050? I'm interested in that card for the 2160p60 10b HEVC decoding, although I'm not sure whether the extra VRAM of the 1050 Ti would make a difference for madVR?

@Patrk G
Could you make screencaps of from your Pioneer of Samsungs "Journey of Color" Demo like these ones You could also use the Pictures just push them on the Pioneer with full light intensity Calibration and Sharpness Setup are very important here

Recently I changed video card (upgraded to a GTX1070) and used again dispcal to calibrate the TV, I set it to 2.4 gamma with 6500K white point... question is...should I recalibrate it to BT2020? Now madVR is set "calibrated BT709 with gamma 2.4", if I change it to BT2020 I see that the video is like losing colours, with DCI-P3 I see it like a middle way, while BT709 is the one more colorful (even if with some video sometimes faces look a bit too red but not with all of them so I guess is also related to the way has been shooted). Can anyone give me some opionion about this? Please :-) thanks ! |

For example, upscaling chroma with bilinear but preserving 10-bit is not better, IMO, than using jinc, NGU, or NNEDI3 for chroma scaling and dithering to 8-bit. Actually, for display 10-bit is fairly unimportant if the dithering is high quality. Dithering doesn't live through compression so 10-bit is very good for source material and processing in >8bit is very important so errors don't build up but for final output and display madVR's 8-bit output with ordered or ED dithering is indistinguishable from 10-bit.

Source: UHD HDR bluray remux GPU: 1070 Cable: HDMI TV: Samsung ua65ks9000 Would you recommend 60Hz 4K 4:4:4 8-bit, or 60Hz10-bit 4:2:2 or something else? Thanks. Kiwi Sent from my SM-G900I using Tapatalk |

I would strongly recommend 4:4:4 8-bit, madVR's chroma scaling is great and 10-bit isn't important with good dithering.
I don't really like the temporal dithering used by FRC displays but madVR's spatial dithering is excellent. The RAM isn't too important for madVR, you can use smaller buffers, but the extra cores/shaders can allow the use of the higher end scalers, etc.

Please what ? A Spatial noise Patern is indistinguishable from a Temporal Approach ? No noise at all the clear Signal that is what you aiming for neither Temporal Noise nor Spatial Noise But you never gonna see the benefit unless you see it on a total 10 bit Chain in and out in Motion And you would need to see the Processing side by side so MadVR vs TV Chip (Signal Chain) anyways (did you do such a test with a 2016 TV out of the Premium Line ? ) And internally you never do any PP in the native 10 bit but above it same the new TVs seem todo Sony Processing it seems upto 14 bit internally (depending on the price you willing to pay). This Scene of course will band extreme in 8 bit and the closer you are calibrated the more visible it will become and a simple spatial patern wont rescue you here in motion. Not sure where these 1 Pixel error comes from in this Demo you can see very small red Pixel in various frames maybe the Sensor had issues, GPU Processing or left Path Tracer artifact

Might sound redundant but could it be possible to add a profile management layer on top? Currently my use of profiles is ridden by nature of source (res, fps, etc) and display (monitor or TV), the issue is that more and more often source content defines the settings to be used, specially when comparing those for anime or real life content, in this regard conditional profiling doesn't apply, and profile hotkeys are disabled since I already have some conditionals...

why not go 23.976Hz 2160p 4:4:4 10bit and get both 10bit and 4:4:4... |

madVR outputs RGB so having the GPU convert to YCbCr and downscale the chroma has always looked worse to me then the VERY subtle noise from dithering in 8-bit. Most people cannot see a difference between dithered 10-bit and dithered 8-bit even with specific test patterns but blurring the chroma is (relatively) obvious in specific situations. Of course 10-bit is nice for the reduced dithering noise but only if you can maintain RGB at the same time, IMO. I can distinguish temporal from spacial dithering, pixels have a minor "shimmering" to them which is more noticeable to me then the static noise from madVR's dithering (I like madVR's dithering without color or motion). Edit: Some TVs might do as good a job at chroma upscaling as madVR, do all processing in at least 14-bit, and maintain 10-bit to the panel but at the same time you cannot say quality is only 10-bit v.s. 8-bit.

The thing is as nice as it sounds to put the PC to the TV it is blasting inefficient on every side just for that small gain especialy with NGU wasting so much energy that is sorry crazy. All TVs currently are Highly Efficient ARM Platforms Partly with their own Processing SOCs and you Put a PC to that todo Chroma upscaling with a Discrete GPU ? If you use that TV as a PC Monitor you should take advantage of this and not use the PC at all anymore for Media Playback only for those that ARM System is to weak for or doesn't support, and merge both in a efficient way.

DLP Checkerboard output?
I was wondering if madVR has ever considered including DLP Checkerboard as an output format?
I have an old Samsung DLP that will do 3D if the input is in Checkerboard format. The MVC builds of Kodi can actually do this, but it currently has some trouble with some of the MVC MKVs that I've made. I know that madVR handles these MKVs just fine, because if I set madVR to display side-by-side, it shows the files properly decoded. madVR just doesn't do DLP Checkerboard output. I'd prefer the simple combo of madVR with a simple media player anyways. I know that this is an old display. I would just like to use it if I could. There was a thread on Kodi's forum when this was asked about a few years ago, before Kodi implemented it. The developer of Bino3D chimed in, as they had implemented DLP Checkerboard in Bino3D. Maybe the information in this thread would be useful: http://forum.kodi.tv/showthread.php?tid=196827 Thanks! |

In my case, Kodi isn't properly displaying the MVC MKV files that I have. (I will attempt to work with the Kodi guy to get that problem resolved, but that's a separate thing.) I know that madVR can decode the files correctly because it can display them side-by-side.
Having madVR have the ability to output to DLP Checkerboard would open up madVR to be used in this instance in all the places that madVR can be used, which is a considerable benefit to madVR. Thanks. |

Yeah the 1050 Ti is more powerful but I'm not sure if the difference is enough to actually allow any better madVR settings to be used. The price difference is pretty big - a jump from £110 to £140.

True but unless I'm totally out of the loop, you can only use madVR within Kodi when using DSPlayer, which is no longer updated. It also doesn't work properly with live TV (at least when using the MediaPortal TV Plugin), whereas using the default Kodi video player works fine.
