Hello...

When I calibrate my monitor to rec.709 2.2 gamma 6500white (PPRo NOT controlling the color scheme)

Do I set the GPU (Nvidia control panel) to:

a) 0 - 255

or

b) 16 - 235

Final output to disc / watching on HDTV.

Thanks!

Hardware or GPU

I work with and teach colorists ... and one of the main things they hammer is that nearly ALL video is meant to be "video" or "legal" range, and that your system should be set for that also. Including ... that video is set on hardware to video/legal range which is 16-235. And then the monitor will still show it correctly, remapping to a viewed full-range image.

Remember, no monitor ever shows video as within 16-235 if set correctly. It naturally maps 16-235 video media to 0-255.

Setting your monitor output to 'full' in the Nvidia card settings will likely mean your image will have crushed blacks and clipped whites, so you'd adjust by then lifting your darks and lowering whites.

Then when seen on another machine, your material will be lifted shadows and greyed whites.

If you export to blu-ray or DVD the last half of the video might be useful.

So if I read you right Neil..... the answer is GPU settings at 16 - 235 ?

Correct.

And I got this wrong when I started out in video, thought it should be 'full' 0-255. Sigh. It sounds logical, but actually isn't. A colorist demonstrated with Resolve (which has many different controls for user settings for color management) and a basic color bars clip what happens each way. Was a learing experience ... as is much of life. Again, sigh ...
