Hello, Macrumors world! I recently thought hard about getting an Apple TV, but it really isn't worth it because my iMac is only around 20 feet from my TV. I would like to get some kind of cable that I could connect to my TV so I can easily watch movies and play games (in HD) on the big screen. This is my iMac model: http://www.everymac.com/systems/apple/imac/stats/imac-core-2-duo-2.16-24-inch-specs.html and my TV: http://www.amazon.com/Samsung-HPT42...1?ie=UTF8&s=electronics&qid=1212941842&sr=1-1 Now, what kind of cord would I need to connect these two at the highest possible quality and resolution? (Keep in mind, it needs to be at least 20 feet as well) Any help would be greatly appreciated. Thanks in advance.
