I am starting to see more and more of these mini computers. As a matter of fact, I currently use one as my daily computer (ACEPC AK1 Mini PC) and have not experienced any issues thus far; and, have been quite pleased with the performance.
Today, I noticed Amazon has a mini pc deal ($30 off the regular price) that you may want to take a look at (CLICK HERE). If I were buying this, I would research it out further; but, for the price and for what you are getting, this may be a good computer to hook up to that big screen. As I mentioned, I currently own a mini pc (similar to the one on sale) and I have it connected to my flat-screen TV (32 inch) in my garage. — Rick @ What’s On My PC
