I'm thinking of getting a mid-size LCD HD television set. For now, it would be used only with cable TV and a DVD player. I haven't had much interest in using a TV as a monitor or to watch photo slideshows or movies from my Mac, since my Mac monitor is big enough for that. But... I might change my mind. I'd like to know what technical considerations I should consider now to let me play with computer-TV connections in the future, e.g., resolution, other specs, having enough inputs of the right types, and so on. I buy a new Mac every few years, so I'll have whatever hardware and software Apple sells, but not a specific model I can name now. I've read this thread about the Mac mini, but I'd like to understand it from the TV-purchasing side. What TV features should I look for?
