“A friend of mine suggested I could use my HDTV as a monitor for my Mac. How can I connect my Mac to my HDTV to watch movies and browse my iTunes library from the couch?”
Connecting your Mac to your HDTV is surprisingly simple. All you need is the right cable and you’re most of the way there. Depending on how new your Mac is, you’ll need to get one of a couple different adapters. All recent Mac hardware uses either Mini DisplayPort or Thunderbolt for external connections. The adapters are available directly from Apple or can be found on Amazon.com. Older Mac hardware includes support for connecting a monitor via DVI.
HDTV screens occasionally offer DVI as a connection option, but more typically rely on HDMI for making a digital connection to set top boxes, game consoles, and other hardware like your Mac. The big decision you need make is whether to get a cable that already has one HDMI end and one DVI end, or whether you plan to purchase an HDMI cable and HDMI-to-DVI adapter.
The best way to get the cable and/or the HDMI-to-DVI adapter is to find an online retailer because local retailers typically only carry overpriced HDMI cables. More details on how to avoid overpriced cables.
