Question: How do I connect my computer to my TV screen?

#1
I have a 42 inch HDTV with HDMI and a laptop with HDMI. What do I need to connect to my TV and use it as my second monitor? What besides an HDMI cord? Anything else?

All you need is an HDMI cable and getting all of the settings correct on both the computer, and the TV. I've tried it. When set up correctly worked great for watching video, but not real good for web browsing. I my case it was just used that way for a short period of time to convince other family members that we should cut the dish bill, and buy a Roku.
