Im connecting my MBP 13" 2.53GHz to my LG TV with MDP to HDMI adapter and its working really good, as soon as i connect it to the TV, the mac recognize my TV and its working perfect. few days ago i notice that when i disconnect the adapter (after i close the TV), the mac think that the TV still connected, even when the TV is off and the adapter is out (when i connect and disconnect the TV, the mac screen "blink"), and i can move windows outside my screen (so they get lost....). all so when i open the system preferences\display, it still show me one window for the mac display and one for the LG TV ??? as far as i know, when i disconnect external screen\TV, the mac should automatically recognize it, and move back to the original setup... in the old Tiger OSX you had to press F7 to change it (for what i remember), but with the new Snow Leopard you dont have this option. maybe somebody here had this problem before and know how to fix it ? , or maybe its software\hardware problem ?
