As another poster stated, VID card with hook up, HDMI, ETC. You said SLING cable from your parents house, are we talking from a distance? Just curious and if so, what kind of distance are we talking about.
I currently own a basic laptop unfortunately it doesn't have an HDMI port and TV I have doesn't have an VGA input. I'd like to purchase desktop in which I would mostly use to view media using slingbox. I plan to sling cable from my parents house. I was someone could give me a recommendation to a good desktop for these purposes and/or specs I should consider in making this purchase. Thanks for your help!
