JVC intros High Speed 2 1080p LCD TVs with 120Hz refresh

Just about a year ago, JVC introduced its first lineup of quickly refreshing LCD TVs, and now the company is reinstating its support by offering up adequate replacements. The forthcoming High Speed 2 series of sets will sport a second-generation version of its Clear Motion Drive technology, which enables a 120Hz refresh rate that was "designed specifically for Full HD (1,920 x 1,080) displays" and is said to "improve motion detection fivefold compared to the original high speed driver." Essentially, CMD II will offer up reduced blurring, flickering, and motion interpolation, and it will work side by side with the fifth-generation D.I.S.T. (Digital Image Scaling Technology) engine on the "JVC-exclusive" 32-bit Genessa chip. Additionally, the trio will sport three HDMI 1.3 ports apiece, a slimmer bezel around the display, and a whole lot less plastic compared to previous iterations. While there's no word on price just yet, the 37-inch LT-37X898, 42-inch LT-42X898, and 47-inch LT-47X898 should hit US shores sometime this fall.

I am a little confused as to why the refresh rate makes the headline. 1/120 = 8.3 ms refresh rate. Hasn't that been done?

This will explain: NO ITS NEW

How does this relate to an 120Hz HDTV showing frames at 120 frames per second? A bit of simple math tells you that 120 is a multiple of 24, because 24 x 5 = 120. So one of the claims of the purveyors of these sped-up monitors is that they can natively reproduce 24p programming, namely, just about every film has ever been shot.

These new HDTVs avoid this awkward 3:2 pulldown process altogether by changing their frame rate to something that's a multiple of 24 by using either frame doubling or interpolation (also called "tweening"). Then, their playback can be as close to native 24fps playback as you can get. That's why 72Hz (24 x 3 = 72) and 120Hz refresh rates are gaining traction. Native 24p playback: Yeah, sounds good.

No only that (above post), but last December's 1080p JVC LCD sets were of the very few that properly deinterlace 1080i FILM signals (along with 1080i VIDEO signals), something that those nice new Samsung LCDs or Panasonic plasmas DON'T DO(!), as their 2007models all failed the film-based 1080i deinterlacing tests from the Silicon HQV discs [test signals], as seen in online and print reviews.

So 1080i program-based material (DVD, HD-DVD, Blu-ray, Cable/satellite etc) should look much cleaner on the forthcoming JVC models [with it's awesome Genessa signal processing], who along with Pioneer plasmas [and some Sharp Aquos models] are some of the few displays that will pass both 1080i torture tests: film and video HD signals.

Note: most of the Sony LCD sets also FAIL 1080i film-based deinterlacing tests.
