I want to show a PowerPoint(PP) presentation on a TV. I have connected my MacBook Pro to 3 different TVs, i.e. Plasma, LCD and a 15 year old 32" Sony. I used the DVI to VGA adapter that came with the MacBook and then a VGA to S-Video/video adapter. I also went VGA to VGA on the LCD. I only get the MacBook DeskTop picture on any of TV's, even when I have the PP presentation on the Macbook screen. Can someone tell me what I need to do to get the PP pictures on any of the TV's ?
