I've had a new LED display since Christmas, and it's been perfect thus far. Until about five minutes ago. About five minutes ago I noticed it shift color, as if it was switching a color profile. It was faint but definitely noticeable. I watched it and kept surfing for a few minutes and noticed it shift back and forth arbitrarily several more times in a five minute time span. The monitor is plenty warm in the bottom left behind, as it's been on for about 4-5 hours now. I've never noticed this effect before. Anyone else noticed this, and does Apple know about it?
