Gamma Overriding Moniter Settings

[Anonymous2343]

I was playing Amnesia earlier, live streaming it, so I had to turn the gamma up so people could see. Well after I was done, I turned it back down to my regular playing setting, which is 1, but when I closed Amnesia, my desktop still kept the gamma 2 setting, and now it's very bright. I tried to change it on my moniter, but it didn't change. When I started Amnesia again, it went back to 2. This has happened before, and it just fixed itself, but if there is another way to fix it, I would love to know.
