Do you care about 240hz vs 120hz

Bump. Wouldn't mind hearing about this as well, I am in the market for a tv. Trying to decide on 120 or 240.

I have heard (read) that 240Hz is preferable for 3D, but does anyone really care about 3D?

If I was to buy a new tv, which I am in the market for one, I would probably get 3-D. I probably would never use it, but it would be a nice thing to have every once in a while.

An "advantage" of a 3D set is that the panels are supposedly a little better (because of the 3D requirements) for 2D.

That's exactly the way I use it and I'm glad I have it. It's a fresh change now and then.

Are LCD panels even fast enough to actually, truly support 240Hz refresh rate?
And since we have no sets that actually can accept even 120Hz input IMHO 240Hz is totally meaningless.

Yes, without actual high Hz input it is definetly meaningless except for the 3D. 60hz of noticeable flickering per eye vs. 120hz per eye where flicker is impossible to perceive. I think the high-end Sonys are capable of 240hz but thats something I heard, not sure. Midrange Sonys just fake it with backlight scanning though.

Are there any 480Hz displays currently being produced?--I heard alot about them a year or two ago but haven't seen any of them.

240Hz for 2D content can insert 3 extra frames for each pair of 60Hz frames to better reduce motion blur.
For 3D it enables the unit to insert a Black frame or equivalent between each pair of 1080 3D frames to reduce/elimnate video crosstalk.

There were many people complaining that the D6xxx series was NOT full HD when in 3D mode (meaning not 1080p) and that the signal was being downgraded when 3D mode went into effect

I don't know if this was resolved or not, but here's a link about it:

Definitely a difference in 3d crosstalk between my 120 Vizio and my 240 Vizio. Killzone 3 suffered from major crosstalk on the 120 hz, but there is almost none on the 240. I don't notice much difference, if any, during normal 2d veiwing.
