Acer AL2051W changes it's contrast

[harobikes333]

I was playing some counter strike and all of a sudden i couldn't play longer that 15 mins because my eyes hurt so bad.

I closed out of the game and realized my monitor was flicking to different brightnesses. It will dim and then get a little brighter. It's not very noticeable unless you are READING anything.... >_<

Any help would be greatly appreciated.
