So I have my Apple Thunderbolt Display set up on my desk where the sun hits the screen for an hour or two each day. I'm typically never around those hours the sun hits it. Until this week. I came home and saw this huge spot on my screen: It disappears shortly after the sun has stopped hitting the screen. Will this exposure damage my screen? Unfortunately it's pretty much the only spot I can place the monitor, due to glare issues etc. Thanks for any insights.
