I was just wondering what you pw(d)7 owners have the contrast and brightness settings set at on your screen. I have just passed 100 hours and decided to calibrate the screen using the set up your display option found in ms media center edition. After going through this my settings for brightness and contrast are still both set below 0. Is this normal. Why does the screen let the user put the brightness and contrast so high up when it can cause damage to the screen?
