i am running leopard on a 12 in pb 1.3 gh computer. i just bought a 40 in samsung lcd tv (4061f) and would like to be able to use the tv as a monitor... so i am using a mini-dvi to dvi converter and a dvi to hdmi cable to hook up the computer to the tv. when it switch the source to the computer, though, i get an empty desktop with a mouse arrow, but no desktop icons, menu bar, dock, etc. i don't think it's mirroring - there is no mouse on the pb screen to try to see what the settings are.... help please!!!
