The colours will be so much brighter...Up to this point the decision was always made for me.
Maybe I should plug in both, that should be twice as good.
As it turns out I did, but that makes sense.I would use DVI. Video cards with HDMI outputs typically have their own sound cards for generating the audio. In an audio workstation you want to disable that audio, if you use the HDMI out the card may try to re-enable that audio and make it your default audio. Better to bypass all of that potential trouble.
