I have an HDTV and it’s fucking fantastic. But understand, 90% of my TV’s use is for video games. Given that I have a PlayStation 3 and that those were designed to be compatible with HDTV’s…games look like shit on cathodic TV’s. I played for more than a year on a square TV with my PS3, and you can hardly read text…it’s terrible. Plus all the options in the PS3 to alter the picture or better fit it to your old TV really don’t help at all…the best thing I had found got my picture stretched vertically, and it sucked. I am SOO happy with my HDTV, and how great my games look on it. Being that I love role playing games, you have to be able to read text without straining your eyeballs. Plus even if there is little text in a game, they look so much more grand on an HDTV.
As far as movies go though…were I not a video game player, I would never buy an HDTV. I don’t see much of a difference between BluRay/HD movies and normal, older ones. I mean there is a difference, HD looks better, but nowhere near enough to warrant an 800 dollar purchase.
Mind you this from someone who loves video games and has no choice but to adapt, but you don’t need to do that with movies and cable TV though, at least not so far, unless you’re real picky. Not in a way that, if you did not, would badly impede on your enjoyment due to how deformed the picture looks, like it does with video games. In fact, I often rent movies digitally from the PlayStation Network, but I always take the non HD version. Costs less, and there’s barely a difference between that and the HD version, anyway. :/
TLDR; fuck 3D. Makes my nose feel weird.
