Uhh, yeah, I think we realize that contrast = white level, and brightness = black level (you did know that, didn't you?), but the problem is that with the contrast jacked all the way up, on virtually all monitors, it will cause damage. Most monitors and TVs don't have an adequete power supply to maintain a high contrast level, so you will get geometric distortions as well. And yes, I calibrate all my monitors and TVs, and I've never had the contrast setting need to be over 50%.
