Gamma/BrightnessFollow

Does a command exist to change the brightness/gamma? My monitor is set as bright as it can go, but at night it is extremely dark. Yes, I have the torch on. :p Maybe it's the game design, but I can't see jack at night...I find myself waiting for daybreak to level, and that plain sucks. Please help....

I had the same problem until I downloaded Power Strip at http://www.entechtaiwan.com/index.shtm
Works great, I couldn't play the game without it.
Good luck.
