So I prefer to play games the right way, without an advantage and whatnot. I can't seem to figure out the correct brightness setting for Fallout NV. I just recently hooked it up to HD with the HDMI cable (Which looks freaking amazing) but the darkness is all screwed up. I have the setting all the way down but I can still see fine in Sierra Madras dark streets. Should I be able too? Is there a way to adjust it so I know exactly what darkness it should be on? Can I just adjust the game darkness setting or do I have to adjust the TV and game? Answers would be greatly appreciated!

I think that's probably fine, the streets are fairly well lit. If you go down to and can easily see everything, then it might still be a bit too light and you may have to adjust your TV itself.
