I have a Samsung HL61A750 and a mac mini 2.53 with 4gb ram. Going to use it as a HTPC and have a question about connections. On my samsung i have 3 hdmi's(which all are being used) and a rgb pc connection that i'm using right now with a htpc that displays 1080p(samsung detects 1080p through my pc connection). My question is will the macmini display 1080p through the pc connection or do i have to connect the mini through hdmi. Also, what is the proper cable to use for 5.1digital.
