It appears that Sony is just like Pioneer and all of their displays every made that have a 1080P/24 input will refresh the image on the screen at multiplies of the original frame. Hopefully my sources are correct. According to one of my sources and a review link from PC magazine there are 5 Sony 1080P 60HZ LCD's that will refresh 1080P/24 material at 48HZ on the screen. Watching 48HZ on a LCD will reduce or eliminate 3:2 pulldown judder but it also will produce some smearing and flickering. It would be better to purchase a 120HZ LCD from Sony since the picture quality is much better compared to the normal Sony LCD screens. Higher refresh rates in general have a better picture quality especially for a LCD screen. 48HZ looks good on a Front projector but not recommended for LCD refresh rates since LCD main weakness is motion blur especially at lower refresh rates. The elements in a LCD screen are slower to respond on the screen compared to other technologies like CRT, Plasma, and SXRD (LCOS) displays.Sony LCD screens that have been added to the listSony KDL-52W3000 (48HZ)Sony KDL-46W3000 (48HZ)Sony KDL-40W3000 (48HZ)Sony KDL-46V3000 (48HZ)Sony KDL-40V3000 (48HZ)QuoteThe KDL-46V3000's HDMI port also accepted 1080p input at 24 Hz (1080p24), and Sony claimed the TV automatically displays this video format using a 48 Hz refresh rate (24 Hz x 2 - an even multiple) that eliminates the shaking/wobbling effect known as judder that is caused when 24p material is converted for display on a typical (60 Hz refresh rate) HDTVthe telecine process. Viewing examinations using 24p video material confirmed the KDL-46V3000 did reduce judder producing admirably smooth panning shots, however, the reduced refresh rate (48 Hz) did introduce additional flicker into some vertically orientated details as the camera panned.NegativesSadly, despite an otherwise strong showing, when displaying scenes depicting lots of motion, the KDL-46V3000 was among the most smear-prone sets I've seen. Viewing angles, however, did affect the perception of color quality. Loss of saturation was obvious in skin tones starting at 20 degrees off-axis from the center of the screen.http://www.pcmag.com/article2/0,2704,2210884,00.asp
I'm the guy who identified the pcmag article on engadgetHD, and I'd like to add the same thing I did on engadget's thread:
I'm wondering where pcmag got the "flicker" from... LCD, being a "sample-and-hold" technology, has no refresh-dependant flicker. Some lcd motion blur is actually attributed to this, since the eye tracks movement smoothly and is expecting an object to be in a certain position, the motion blur (not signal/source based) is a trick of the eye. If you flicker the backlight at 60hz, you can actually eliminate the appearence of motion blur.
But lcds backlights dont flicker. So I wonder where they're getting that from. The only "flickering" with an LCD display is with an interlaced source thats being incorrectly deinterlaced.
With this in mind, it wouldn't matter whether the refresh rate is 48, 72, or 120 flicker-wise, they'd all appear the same. Where 120-hz benefits an LCD seems to be in its response-time blur, and MOTION RESOLUTION (as discussed in hdguru's article http://hdguru.com/?p=187
48hz should be perfectly fine for movies.
