MacBook Pro Display too dark for movies

This is a deliberate duplicate to MacBook Pro Display too dark for movies, which I'm creating because I had the same problem, and the answer didn't solve, and I think I landed on the same setting the author had vaguely remembered, and it solves the issue.

Original issue description:

***

How do I adjust the MacBook Pro display/screen to view movies/TV properly? I view Netflix, I might play a DVD, or use iTunes. The screen brightness does not accommodate darker scenes. It was working for a while; the contrast(?) changed when the onscreen toolbar appeared and disappeared. Then, the darker scenes appeared viewable.

Apparently, I stumbled on the adjustment at some point, because the screen adjusted, but I don't remember what I did (boo-hoo).

Your help is greatly appreciated.

What solved this for me: adjusting the Contrast. I was tolerating my MacBook Pro with this set way too high for a very long time, making dark parts of videos, games, etc., unusably dark.

It solved it to simply return the Contrast to "Normal" position.

Contrast is found at Apple > System Preferences > Accessibility > Display > Display contrast (http://osxdaily.com/2014/10/22/increase-contrast-mac-os-x-yosemite/). It took me forever to realize this, and that it didn't relate to the primary Displays section.

I'm stoked to have my dark video / game scenes visible finally, and wanted to share in case someone else ran into this. As I mentioned, I tried the steps recommended in the issue-raised that I am here duplicating (resetting the SMC and NVRAM), and there was no change; the problem was in Contrast all along, just as the original author suspected.
