recently bought new HP laptop with HDMI capability late 2008. first time i tried hooking up laptop to my plasma via HDMI output, it worked perfect, my plasma took over the main screen on laptop - thus letting me use windows media player to watch movies/games and pictures via plasma. However after first time, i have been unable to get control on plasma. my screen saver screen goes on TV / Plasma however everything else will not pass over to plamsa. i can get my mouse/curser on plasma but only thing i can do is right click on mouse on nothin comes up besides view/arrange icons etc. when i go back laptop and click on window media center is opens on laptop but plasma remains just my screen saver, it sounds like sound is going threw, but for past 4 month i cannot figure out how to get control and use plasma via HDMI, i even changed HDMI cables and output on tv but didnt work any help appreciated?
