Is the DB-15 port on the back of my flat-panel TV digital?

I am going to use my Samsung 46" flat-panel TV (1080p) as a monitor for my MacBook laptop and I'm not sure about something. The route I'm taking to do this is using a mini-DVI to VGA adapter on my MacBook then running VGA into the "PC" port on the back of the TV. A guy from my job tells me VGA isn't digital, it's og. This is strange since a DB-15 port is VGA (at least I think it is) and it's on my bran-new 1080p flat-panel. I wouldn't think Samsung would mark an og port "PC"... Anyhoo, is the DB-15 port a digital input or should I use something else? I don't know if anyone makes a mini-DVI to HDMI adapter.... Please advise, thanx.
