if your PQ curve is incorrect with a proper SDR calibration than the calibration is not the problem it'S the conversation.
so changing the calibration to get better PQ is the wrong way to look at it what you should look at is the conversation. |

You can pick any gamma you want with MadVR, but with a standalone player gamma 2.4 is recommended as it’s the likely target for the conversion.

@huhn: BT.2390 standardizes the mapping AFAIK, and there are only 2 more options to choose from for tone mapping, "clipping" and "arve curve", the latter I'm not familiar with...and I really don't like the cliping approach even if the rest of the curve is prefect

Hello.
I am not sure it is the best place to discuss on evolution request and if there is a more situable/dedicated area, please let me know. The subject is linked to the syntax used in the profile rules to execute an external program when a profile is activated. The goal is to launch a programm depending of the aspect ratio AR of the movie. This program will modify the position of the mask of the screen to fit the aspect ratio of the movie. Today , with the actual behaviour, is it possible to add a variable in argument with the program to execute. This variable would be , of course, the value of the numerical parameter AR If it is possible, what is the correct syntax ? for example the line command to execute could be : c:\mask.exe AR or c:\mask.exe Value(AR) If it not possible today, is there a possibility to implement such behaviour to be able to use some numerical value managed by madVR into an external program ?

Today I took a few hours, the Godfather Blu-ray and played it on the OPPO 103 and MadVR.
I tried every upscaling shader and ended up using NGU AA very high. Still, the OPPO seemed better with less noise. But I think I found a way to make both images identical, there's a noise reduction setting on nvidia control panel, if you set it to 30~50% the sharpned grain by MadVR becomes less noticeable and the noise patterns are almost identical. I know the newest MadVR have denoise feature but since I'm using Jriver and I use BD and UHD BD menus I can't update. Tried MadMax UHD recently with the newest MadVR and JRiver and there were subtitles only if the pop up menu was open. (not blaming MadVR, just commenting). I would like to ask you, since MadVR is doing all the upscaling do you guys use Cinema mode with your display? I believe Game or Graphics/PC mode would give you a more raw image but since MadVR is dealing with it, is there a point in using it? |

(this is assuming Cinema mode does its processing in 4:2:2 while PC is 4:4:4 or RGB, which is common)

The BT.2390 curve is converted to an SDR gamma curve, so you are really attempting to track an SDR gamma curve with an input that is too bright.

Noise with madVR's upscaling has been mentioned a few times recently. It is surprising the Oppo is less sharp or it is using some type of denoising filter. The HTPC shouldn't be creating noise not found in the source. Have you tried sending a limited range signal instead of a full range signal to see if your display is doing a poor RGB conversion? Combining NGU Sharp with the free version of reduce compression artifacts can sometimes help but will soften titles with film grain.

On my previews TV when 4:2:2 mode were on I could barely see the text, so I'm not enterily sure. https://ibb.co/ges2n8 https://ibb.co/cYvcLT crap cellphone pictures from the screen but I believe it's possible to have an idea. |

ges2n8 looks like 4:2:2 to me.

That's what is recommended by rtings review of the Sony 900E. Actually, setting sharpness is quite dificult to do with 4k because you can't spot on the right point where noise starts to be added. I'll stick with graphics/game mode from now on. |
