Anyone have an LCD with 120Hz refresh rate. Want to know if its worth it?

Answer 1

I don't have one, but I have seen lots of tests, and it is not pretty.
The first generation, they just insert a gray or black frame between two repeated frames.
The 2d generation will be using motion estimation/compensation to interpolate between frames.

In "demo" mode (carefully pre-selected material) it looks OK, but in arbitrary material, it can be worse than 60 Hz. I say, wait for next year to fine tune the algorithms.

Answer 2

It's worth it, it sharpens up the Hi Speed action so it's not blurry anymore....
