I'm sorry if this is a ridiculous question, but i would really like to create some custom grayscale patterns to calibrate my tv. At the moment, I'm just using MS Paint to create a few squares on a 1080p background. My questions is, what RGB values should i assign to each level to get an accurate grayscale ramp from 16-235? My thought is that it would be a consistent step between each, but I'm honestly not sure. There's a good chance I'm also thinking about it completely backwards, so any insight is very much appreciated. It's just much faster for me to skip through slides on a USB than use a blu-ray. Thanks again!
