My TV is, I dunno, about 26 years old. It works fine. I just can't justify the cost of buying one of those big screen things, which I would never watch anyway.
I like my sports on a 32" LCD...so I don't have to sit on top of the set.
if you got one of those things, you might want to view your smartphone through it. I find these LCD screens are great with graphics, but the colors don’t look too natural. I recently got a cheap 32 for about 250. It has a 3 or 4 hdmi connectors, and most people will have these screens in a few years. Not suggesting anyone replace their tv to see their smartphone.
