So I buy a new 55" LED HD TV with 120Hz refresh rate. Groovy. I get it going at the pad, and notice everything coming in is at 60Hz. Settings on the TV are set to max, yet I still get incoming 60Hz. So I call Direct TV, and they tell me EVERYTHING anybody is getting (whether via cable satellite, etc) is sent out at 60Hz. The higher rated TV's convert to 120 or 240 (to some kind of extent), but the signal coming in is at 60Hz.
So.....what's the point in 120Hz refresh rate if you aren't receiving that to begin with?
One, you're ready for when they DO start broadcasting at higher refresh rates and two, you can now attach your computer (and, possibly, other devices like Blu-Ray?) and use the TV at the higher, better for the eyes, rates. :)

By that time he'll need a new TV anyway. ;D ;D
I've got a 46" LG with those same specks. This is my first decent flat screen and this is news to me. I just figured it was a 120sig already. ;D
It's been 60Hz for a very long time. If your TV does some sort of awesome smoothing, it can interpolate between frames. Essentially comparing frame 1 and frame 2, and creating an intermediate frame that bridges the gap between the two, smoothing out motion, making everything a little more fluid. In a 240Hz TV, there are actually three frames between each incoming 60Hz TV frame, so this smoothing *can be* even better. In reality, I haven't seen much advantage to this, but I'm no videophile. However, 60Hz is right at the "flicker" boundary, where you can start to see a screen flicker. 120 is probably a let less noticeable in this regard.
Of course, time code gets weirder--film, until digital film, was shot at 24fps, modern TV is shot at 60fps, progressive scan, and all the pre-HD era stuff (60 years of TV) was shot at 29.97fps, and broadcast at 30 fps, which meant that the system had to drop 2 frames of the first second of every minute not divisible by 10-really. The short answer is, your TV might look better than a 60Hz tv, dependent on the original source, but no, it's not broadcast at 120Hz.
Thanks for the info! The guys selling TV's make it sound like you have to have that 120 or 240 hz TV. And, you can't even use it yet. It's a non-factor. ;D
