I'm trying to use 0-255 in MadVR but it doesn't work correctly, it is making everyone blacker than black same as a TV with no support.

What is the easiest test to check ?

x7007, you use the Nvidia settings mode and select "Full 0-255" in the Nvidia Control Panel Video color settings panel, and likely also want to set the Video Image settings to use Nvidia tuning options, and then adjust the other tuning settings to fit the need. It takes time and is easiest with a color sensor and calibration software - which I assume is what you are trying to do :)

I set my control panel to show you the setting location/option, but since I don't need to have that kind of control I keep mine set using video player settings most of the time.

Here are the 2 modes for the Video Color settings - Nvidia and Video Player - you set 0-255 in Nvidia mode and leave it there for effect, and a view of the other panel you may need to adjust, the Video Image settings.

Hey, thanks.

But what about MadvR there is a setting there to change.

changing from nvidia panel doesnt seem to have any effect the last time I check.

This monitor should be 0-255 but if I try to use it in the video MadVR it just make everything blacker than black.

There is Lav Video Filter too I don't know which one to choose. Usually they say it's the best to do the convert from the Lav Filter and not from the Renderer which is MadVR.

x7007, the Nvidia setting is for the output to the screen, the conversion is to set the format for the file converted. I don't know what else to tell you except keep experimenting, and/or try posting in the MadVR forums - or another support forum that covers MadVR for help.

This is a bit old, but maybe it might lead somewhere useful, look for google hits like this:

When you find a fix, please post it here and in the MadVR forum :)

Two other notes from your screen images above, some complaints about MadVR and using CUVID on Nvidia - to be avoided, and make sure you have the input set to Video range and all outputs set to 0-255 to be consistent.

Look here, 0-255 just ruins the picture if you try to use it, a lot of the details are gone.

x7007, it is operating correctly :)

RGB: Full vs. Limited - Reference Home Theater
http://referencehometheater.com/2014/commentary/rgb-full-vs-limited/

Read the whole article, but also note this later Q/A:

"Q: When I choose limited, I get a washed out image. When I choose full, shadows are crushed. Which is correct?

A: If you are on a TV, then Limited is still correct. The washed-out image is caused by your brightness setting being too high. You should use a calibration disc, like the free AVS 709 disc, World of Wonder, or Spears & Munsil, to set this correctly. Then your black levels will be correct in limited, you will see shadow details, and it won’t be washed out."

The subtle effect of filling in missing data is working as expected. I prefer the crushed blacks obscuring "details" vs. the washed out "details"

You can correct by adjusting the additional Nvidia video controls for contrast/brightness to bring out the details.

There are other tabs/settings - Gamma is important - play with it to get 0-255 to do what you want.

The video encodes 16-235, games / pc apps 0-255 - the conversion can't extract detail that isn't there, and the correct as you can see with the encoding app also can exert it's own influence.

Start by setting the Nvidia Control Panel "0-255 Full", Apply, go to all the other tabs and select Nvidia and adjust the settings, Apply.

Explore all the Nvidia tuning options, Apply, and if needed reboot to make sure it is taking effect.

If you can't bring out details, they aren't there, the washed out areas give contrasting areas in contrast to the "details" - when properly placed in the black scale they can "merge", people get paid big bucks to tune this stuff, it is an eye and talent you will gain over many hours of adjusting.

Everything is working correctly, you just need to learn to tune it all for your enjoyment :)

x7007, color balance is likely different. The Nvidia changes should do something, if they aren't changing the video image, then check your player settings - try other players too, don't get caught up in a rut - if it ain't working, move on to something that does work, change things up till you find something that works. Then you can circle back to the tools you want to use knowing that it can / should work, and you can focus on finding the correct flow / settings.

Try MPC-HC and VLC, among others.

If you haven't already found it, this article talks about settings for potplayer, MadVR, MPC-HC.

There are lots of other good links near the bottom.

This one looks interesting, with a check for proper MadVR 0-255 conversion settings:

http://www.ezoden.com/htpc/49/tips

"madVR

1. There might be a conversion problem (16-235 -> 0-255) with madVR. To verify that the conversion is done correctly download the pattern "2-APL Clipping.mp4" of this pack AVS HD 709 - Blu-ray & MP4 Calibration that comes from this site Avsforum (the pattern is in the "Basic Settings"). "

That's a subset of a much larger treatment of setting up an HTPE

I can't change other player from pot player, it is the best one to use and easiest with all options to choose. I'll check the the things you said, it seem exactly like they say , but I see more black than normal. so 0-255 shows what it should be shown from their test.

Can you post a screenshot from some movie you have and we'll compare ? How can I take a screenshot with the effect of 0-255 and 16-235, because sin potplayer there are Source Frame and Screen Frame. or there is other way to take a screenshot ?

x7007, sorry, I can't help you out, but I am sure if you go to an AVS Forum like these, you can get into it for a nice long discussion.
