If you don't want to get into it too deeply I suggest you set white point and brightness to native, tone curve to BT.1886. Black point compensation on for the first try, off if that calibration is not good near black.
This method doesn't try to fix the white point but white is relative for humans and without a lot of testing and doing it right HDTV calibrations are generally better without targeting a white point, IMO. You sacrifice too much to sort-of fix white. I suggest you look at the Display Calibration thread for continued discussion of this topic. There is some good information there and it is nice to avoid clogging up this thread with display calibrations.

The rest of your questions depend on what you're trying to do or are after. After you generate a profile of your display you can generate a 3D LUT over and over changing the options however you want. That only takes a few minutes per 3D LUT and doesn't require any remeasurement. |

It's a bit softer, though, which is corrected well by SR.
SR also corrects some of the bloating by super-xbr without A-B, but this is mainly limited to bloating of dark areas since SR in GL has kind of thinning effect for dark lines. The ringing/bloating of bright areas by super-xbr isn't corrected as good, that's where super-xbr A-B comes in. |

I also had dropped frames. I've tried to disable deinterlacing, but I still also noted dropped frames, despite using bilinear basic filters. Maybe the problem is with hardware. I never took time to test with DVBViewer.

Guys i need help, i aways used madvr in tv levels and the gpu on full range... My tv cleary don't suports full range, all other aplications turn darker and saturated...
But i downloaded avschd patterns and when i play the black clipping pattern all the bar are flashing so i tried others And the only that keep 16 black and 17 flashing is madvr 1-255 and gpu full But how this is possible? If i can see cleary on other aplications that the tv don't support full range, also on madvr full range the movies are darker and oversaturated...i really don't know what is happening Its possible to be a Intel driver bug?

are you getting a different result here?
https://www.youtube.com/watch?v=9TI9f1zxucw +-1 level scaling can make more levels visiable. is DXVA scaling used? |

This was more apparent because when I turned on forced deinterlacing in madVR or forced it off there's no dropped frames. At first I thought it was video mode/film mode detection and that may be responsible from some dropped frames too but its best stuck to video only for TV. It might help to understand how the auto detection works to try figure out why madVR keeps switching deinterlacing off/on. Edit # further testing confirms the same behavior in mpc-hc. Never dropping frames with deinterlacing off. Keeping deinterlacing off in madvr and forcing it on in lav such as enabling yadif once again means the occasional dropped frames. The same occurs when using hardware deinterlacing in lav and forcing it on. How the hell can I work out how to solve this?

Is Very strange if i set madvr to tv anda gpu to full 1 to 25 all flashes Ir ser madvr full and gpu limited i get 19 to 25 flashing but with madvr full and gpu full almost the same happens... I found that madvr 1-255 and gpu limited works but i don't want Intel dithering...

edit: btw your results are not strange at all, that is exactly what you would expect to happen. Picture information is 16-235, so when set to full madVR expands 16-235 to 0-255, clipping 0-15. If set to limited madVR outputs the untouched 0-255, which includes the blacker than black 1-15 bars which you incorrectly see. The GPU setting simply compresses 0-255 to 16-235 if set to limited and outputs the untouched 0-255 if set to full. The GPU always assumes it is 0-255 so if you set both the GPU and madVR to limited you get double compression.

I aways used madvr on tv levels and gpu on full levels But when i run the patterns the resulta are strange Lets show you: Madvr: 16-235 gpu: 0-255 = all bars 1 to 25 flashing similar to limited limited But with brackground more darker Madvr: 0-255 gpu: 16-235 = 18 to 25 flashing Madvr: 0-255 gpu: 0-255 = 19 to 25 flashing If i set madvr 1-255 any range on gpu flashes 17-25 But my tv don t have hdmi black level option also don't have any levels Options, and with gpu to full all colors on desktop and internet and everything else become Very darker without any shadow detail and oversaturated on reds... I really don t know more what levels use... With thats situation i tried 3dluts with all settings and only terrible results

The only other option is madVR 16-235 and the GPU full, but this clips your desktop. These are the only two options if your TV does not support full range. But it sounds like your's does if you can see all the bars with madVR 16-235 and the GPU 0-255? Maybe you can recalibrate your TV for full range input? I know some TVs I have calibrated did not have an option for blacklevel but I could change it by changing brightness and contrast. Set madVR to 16-235, GPU to Full, usually you raise brightness to bring lower numbered bars visible and lower contrast to bring higher numbered bars visible. Sadly sometimes the manufacture has 'brightness' and 'contrast' change different aspects so these adjustments might not be right or even involved in the black or white level. You want to adjust until you can see 1 and 254. If you can adjust so all steps are visible you then change madVR to full range and you should only see 16 and 235 (and the desktop should look correct).

When set to 0-255, madVR clips 0-15? This is news to me. What about 236-255? Also clipped?

Just wanted to thank madshi and guys over at LAVfilters to help enable MVC playback. Just one thing: sometimes madVR does not switch to 3D stereoscopic mode and resolution when I play back an MVC video. That's a problem because I'm outputting at 4k and thus the video is played back in 2D at 4k. Maybe having some kind of 1080p23@3D display mode would do the trick. Right now I'm using two profiles, one with 4k resolutions and one with 1080p. Using 1080p display mode always ensure that 3D stereoscopic mode is activated. Using 4k display mode don't.

In case anyone is curious to know, a 2-core Broadwell cpu with Intel HD 6000 can upscale 1280x720p to 2048x1152p using NNEDI3 16 neurons for chroma and Lanczos 4-tap with anti-ringing filter for luma without frame drops. Render time is about 20 ms on my computer. Picture quality is quite good for this combination. and noticeably superior to DXVA2.
NNEDI3-16 chroma however, cannot be selected to upscale 1920x1080p to 2048x1152p or just chroma upscaling by itself (normal size) without lots of dropped frames so you still need to use a different chroma upscaler like Mitchell-Netravali. I am not sure why because I thought the jump from 1080p to 1152p would be less intensive than the jump from 720p to 1152p. Is there a mathematical pixel limit for the scaling or something else? |

What about super-xbr100 + AR + Bicubic150 (downscaling) + SuperRes (1) for 720p sources?

I never liked the "look" of jinc on luma though. Didn't test the second combo, but I'm sure it would be fine as well. |
