The quickest and easiest way to hook your Ubuntu computer to a TV is by following the simple steps here:
A few clicks of the mouse... desktop or laptop, old tv or new tv, cable type and it recommends what is needed to get your computer onto your larger tv screen. Perfect for playing computer games, watching Youtube videos, internet movies, or whatever you would like.
As seen ther photo below, I hooked up a little Acer AspireOne netbook to our bedroom TV. The Ubuntu picture on TV is very clean and crisp. I watched a documentary on Youtube the other night. Much better than being huddled over a computer screen.
