laptop to tv by hdmi not responding

[rastapus]

hej i've just got my first laptop (acer 7738 with vista home premium) and i am trying to connect it with our LG 32" plasma television (50PG60).
I am using a hdmi-hdmi cabel for connection, but when i'm trying to find an extern monitor in the mobilty center it can't find anything.
so - what's the problem here?? me or the laptop
