Ah-ha, thanks for all these long explanations. I think I am starting to get the hang of it.
1) This is one of the test images from Spears&Munsil. It should look like this (almost all white blocks are visible, a thin white stripe at the center, small darker square inside colored squares):
2) With my current setup, it looks like this (white blocks are mostly gone, a thick stripe at the center, colored squares have no small dark square in them):
3) When I switch madVR output from 0-255 to 16-235, I get this (whites and blacks are greyish):
So I am starting to understand what you are saying, that my levels are already correctly setup, and both pc and tv are set to 0-255, which results in image #2
. Calibration wise it is correct, but I loose the extra information in the video signal, but gain similar colors for desktop and videos.
If I want the best quality video and retain BTB/WTW information, I need to keep nVidia at 0-255, switch madVR to 16-235, and switch TV to 16-235. This should keep give me 1), but desktop color will be crushed.
I assume madVR output and TV settings should always match, right? So I can also try:
nVidia 16-235, madVR 0-255, TV 0-255
nVidia 16-235, madVR 16-235, TV 16-235. <- I suspect this could give me similar desktop & video colors, and I won't lose BTB/WTW. Any disadvantages for doing this?
