Connecting mac pro to a Plasma screen.
I need some advice with connecting my Macbook Pro C2D to a 42inch Pioneer Plasma screen via a DVI - HDMI lead (which I have). I'm having trouble getting the screen size correct on the Plasma. When I look in system preferences I can't get find a correct resolution that displays the whole of my desktop. Is there any 3rd party software I need to download?
Thanks
