Newly
LCD-focused HDTV maker
Syntax-Brillian has teased a few details about its plans for CES, bringing a high-end feature from
CES 2007,
120Hz, to its mainstream
Olevia brand. No word on specific models or prices, but 1080p and 120Hz motion processing are the highlights of the 42-, 47-, 52-, 55- and 65-inch LCDs. Rounding out the CES 2008 plans are a JPEG/MP3 support, USB firmware upgrades, a new universal learning remote, and a whole slew of Olevia-branded accessories including HDMI cables, wall mounts and a wireless/waterproof LCD. Expect more details in a few days, and look for these HDTVs to hit shelves in the second quarter.

I own an Olevia and I love the picture quality and their price too and I love tech as much as the next guy, but is 120 htz really necessary? Isn't 60fps as fast as the human eye can see?

With 60hz sets, you can evenly devide televison (30 frames per second) and video games (sometimes up to 60 frames per second), but not film. Film is 24 frames per second which does not fit into 60. In order for it to display on a 60hz, it has to go through a process called "3:2 Pulldown", which you can learn more about online. Basiccaly it gives some frames more time than others to get up to 60fps to match 60hz. It usually isn't all that noticable (if done right), but it can produce some problems, and if compared side-by-side to a 120hz, the latter looks smoother.
120hz: divisble by 30, 60, and 24.

This is true in theory, but so far not in practice. AFAIK, there are currently no 120Hz LCD sets that do actual 5:5 pulldown. Instead, what you usually get is regular 3:2 pulldown (not always done properly) @60Hz times two. There are some 120Hz sets that do a sort of frame interpolation, but this is not true 5:5 pulldown either.
AFAIK, your choices for non-interpolated judder-free 24p playback are a Pioneer plasma with 3:3 pulldown @ 72Hz or some front projectors.

common misconception...

i know i can tell if my crt monitor refresh rate is set at 60hz instead of 85 or more. I can also tell the difference between a game running at 60fps and a game running at 100fps
the outer edges of your eyes (and peripheral vision) are even more sensitive to light strobing.
i remember there even being a recent article on engadget about 60hz flourescent bulbs aggravating migranes.

I'm actually aware that 120hz sets do not handle 24fps properly, but I didn't know that they take 60hz and multiply it by two. That sounds basically the same as 60hz because they are just adding frames to the video (if I understand correctly). What's interesting is Pioneer's KURO series may not take 24fps perfectly either. I read on AVS (where they were argueing quite a bit about this) that it is actually more like 23.9333333fps, which would not divide exactly into 72hz.
Even with this unknown, it probably doesn't hardly matter. You probably couldn't hardy preceive it if you wanted to! Pioneer's are still the best plasma sets out there!

I wonder what the contrast ratio will be?
Hoping for 10,000 to 1 or better

I do understand about the film being shot in 24fps, but why not have a chip that when watching blu-ray or HD-dvd's goes into a 24fps mode? That or why not shot movies in either 30 or 60fps? Still at the end of the day i'm always glad to see tech evolve.

"That or why not shot movies in either 30 or 60fps?"
Because then they wouldn't look like movies. ;)
Aesthetics aside, the biggest hurdle against doing this with film has been added cost. Or maybe it was because you lose the PAL markets for video. OK, it's complicated.
Even with digital acquisition, imagine doing a CGI heavy feature. You're effects budget would go up along with the frame rate.
I'm still holding out hope for 48fps features somewhere down the line, though.

Those 120hz sets make movies look horrible. Gives them a "soap opera" look. Takes away from the movie experience by making movies look TOO good.
