I was doing my due diligence and learning various shortcut keys. I was surprised to see that there was a shortcut key for contrast settings - namely, ctrl+opt+cmd+"." or ",". I started changing the contrast without keeping a mental check of how many ticks I was going up and down. Now I don't know what I had set it at before. I thought I'd just go to my color settings, change the profile to something else, then change it back. However, doing that didn't change the new contrast setting. In other words, if I turn the contrast wayyyyyyy up so that it's practically white and black, then change the color profile, then change it back to my standard, the contrast was still tweaked wayyy up. Any advice?
