Toshiba LCD Flat Panel 52XF550U Sound and Vision July/August 2008 review information
The Toshiba XF550U series offer true 5:5 pulldown according to the following new Sound and Vision review. Perhaps one day Toshiba might release a BLU-RAY player to take full advantage of these new Toshiba displays. On the new Toshiba XV540U and XF550U series of displays when the Film Stabilization option is set to standard mode the Toshiba’s will perform true 5:5 pulldown.
"Notably, the set supports 1080p/24 input signals from Blu-ray Disc players, with a "5:5 pulldown" option that preserves the original film-frame sequence."
"The ClearFrame 120-Hz feature can be switched on in the menu. Motion Vector Frame Interpolation processing is used to derive additional frames from the incoming video signal; with a standard 60-Hz source, this effectively doubles the number of video frames being displayed per second. A Film Stabilization option also provides Standard and Smooth modes for handling film-based programs. When sending a 1080p/24 signal to the TV from a Blu-ray player, the Standard mode engages 5:5 pulldown (each original film frame that's been encoded to video is displayed five times to hit the TV's 120-Hz refresh rate). The Smooth mode, meanwhile, adds processing to eliminate the motion-judder artifacts that are part and parcel of the film-watching experience.”
Clear frame appears to be artifact free when smoothing 60HZ video sources at 120HZ refresh rate.
"As a movie fan, I proceed cautiously with motion-interpolation modes on 120-Hz LCDs, some of which can impart an unnatural "sped-up" look. But Toshiba's ClearFrame feature proved effective and artifact-free at all settings, including the judder-fighting Smooth mode. As my Blu-ray player supplied a 1080p/24 signal with ClearFrame and Standard Film Stabilization enabled, pictures looked razor-sharp even in complex tracking shots along fences or across signs."
