console usage?

so you can use your pc via the vga/dvi connection and a hd source into the hdmi connection.

Basically, your GFX card's connection ports affect what connection on your monitor you will use.
VGA - VGA cable
HDMI - HDMI cable
DVI - DVI cable
Or, if your GFX card has a connection that your monitor does not, i.e. GFX card is DVI but monitor only has HDMI port, you can use a DVI to HDMI adaptor.
Really the same but personally, I would always go for HDMI.
I'm running my 8800GT which only has 2 DVI ports via HDMI to my TV using an adaptor.
