Brightness glitch?

The default setting in Reach, 3, and ODST, for me at least, is very annoying to play on (if I play on default brightness then I have to keep my night vision / flashlight / VISR permanently activated). So then I increase it to “Higher”, but the next time I power on the Xbox I find that my brightness setting always gets reset to “Normal”. Can anyone help?

Try adjusting the brightness and contrast settings on your tv maybe?
