Current in production 1080P/24 LCD flat panel Displays with LED backlighting
**Current in production 1080P/24 LCD flat panel Displays with LED backlighting (List 2 of 6)** Here is a updated list of current in production HDTV displays that accepts a 1080P/24 signal for those that are interested in that feature to completely avoid any 3:2 pulldown problems. Feel free to add to the link as this would be useful information for some people. If you see any errors feel free to comment. The data comes from verification from manufactories manuals,websites,magazines and other sources. Note: only displays that have a 48Hz, 72Hz, 96Hz, 120Hz, and higher refresh rates with 1080P/24 input support are included on this list. Displays that are 720P and accept a 1080P/24 input are not included on this list. Displays that are only 60Hz refresh rate and displays that incorrectly display 1080P/24 are not on the list. Displays that use a 3:2 pulldown process when a 1080P/24 signal is applied are also not included on the list. ** Accuracy Warning** It is recommended one does their own research since specs can change and professional reviewers can make mistakes or receive pre-production models that have different specs from the official release version. From time to time as more information is learned about a display it can end up being removed or added to the list. The following are all true 1920 X 1080P native Displays Important Note: Historically so far LCD's with Local Dimming LED backlighting have a better picture quality when compared to LCD's with Edge-lit LED backlighting. LCD with Local Dimming LED backlighting (flat panel) Sony KDL-55XBR8 (1080P/24 correctly refreshed at 120HZ when Motion Enhancer is turned off) Sony KDL-46XBR8 (1080P/24 correctly refreshed at 120HZ when Motion Enhancer is turned off) Toshiba 46SV670U (1080P/24 correctly refreshed at 120HZ when ClearScan is turned off) Toshiba 55SV670U (1080P/24 correctly refreshed at 120HZ when ClearScan is turned off) LCD with LED backlighting (without Local Dimming) (flat panel) LCD with Edge-lit LED backlighting (flat panel) LG 42SL90 (1080P/24 correctly refreshed at 120HZ when Truemotion is off and Real Cinema is on) LG 47SL90 (1080P/24 correctly refreshed at 120HZ when Truemotion is off and Real Cinema is on) Samsung UN32B6000 (1080P/24 correctly refreshed at 120HZ when Auto Motion Plus (AMP) is turned off) Sony KVL-40ZX1M (1080P/24 correctly refreshed at 120HZ when Motion Enhancer is turned off) Last edited by HDTV1080P; 02-07-2010 at 09:53 PM.

Yes its possible to convert 60 to 24 but doing so can introduce motion artifacts.
The ideal display should be able to accept a 1080P 24/30/60 fps signal from a source that is 1080P. BLU-RAY and HD-DVD movies on the disc are encoded at 1080P/24fps. The advantage of having a display and BLU-RAY player both supporting a 24fps signal from the original source is that one bypass the need of the display having to do a 3:2 pull down. BLU-RAY players and HD-DVD players can introduce motion artifacts with 3:2 pull down when 24 frames is converted to 30 frames. Doing so adds six additional frames. The problem is that jitter during motion can occur. It is possible to do a reverse 3:2 pull down and go from 30 frames to 24 frames which also can lead to motion artifacts. There are several articles in magazines like Widescreen review and Perfect vision that goes into much more detail about converting frames and the 3:2 pull down process. In general when watching BLU-RAY movies it’s better to keeping the source and input for movies at 24FPS to avoid slight motion artifacts. More and more displays are converting 24FPS material to refresh rates of 72, 96, and 120 for maximum display quality. Flashing each frame 3, 4, or 5 times improves screen imagery that matches the quality of the original film. |

I don’t know of any sets currently on the market that convert 60P to 24P, but it would be possible to do if that feature was in demand. You would need to then up the 24HZ again to eliminate the flicker. Its better that the display accept the input of the source material then having to convert it. For example if someone is playing a Playstation 3 videogames that was encoded in 1080P/60fps then one would want the display to accept 60HZ signal and display 60HZ or 120HZ refresh rate. 1080P/60 takes a lot of bandwidth and currently no studio broadcast cameras support 1080P/60. Many of the studio cameras broadcasters use 1080P/24 standard. 35MM and 70MM film is also converted to 1080P/24. Broadcasters do not send the signal out at 24HZ since very few monitors support 24HZ. Also the problem with 24HZ is that people would go nuts seeing their monitor flicker every few seconds. Higher refresh rates are always better. Monitors that accept 24fps input have to convert the 24HZ signal from BLU-RAY or HD-DVD players to 48HZ, 72HZ, 96HZ or 120HZ in order to eliminate the flicker of 24HZ video. The higher the refresh rate the less motion artifacts one will see.

** UPDATE**
Found new specs that show the Panasonic supports 1080P/24. This information was not available before. The Panasonic appears to be a good 1080P projector. I have not read reviews on it just the specs. 11,000:1 contrast ratio is good for the Panasonic. Sony and JVC have a 15:000:1 contrast ratio. The Panasonic does not accept 24HZ input. That feature is only useful if you plan on getting a BLU-RAY or HD-DVD player that supports 24fps. Looks like the Panasonic can be purchased for around $3,000 on line which is $700 cheaper then the Sony. I would recommended the Sony front projector if you own a Pioneer or Sony BLU-RAY player that supports 24fps. http://www.calibex.com/PTAE1000U/zzc...0--search-html The cool thing about BLU-RAY and HD-DVD is that since many movies and TV programs are filmed in HDTV are using 1080p/24 production format that for the first time consumers can watch the material without the material needing to be converted by the player. When these programs are transmitted for broadcast they need to be converted and 6 frames added before broadcasting interlaced at 1080I/30. Last edited by HDTV1080P; 02-15-2007 at 11:24 AM.

Wow thanks guys. That makes sense. I read a review at Projector Central that said the Sony Pearl had a soft image when working from Blu-ray and HD DVD sources.
If that's not the case, I'll probably go for a Sony  PS. I have a Sony BD player so it makes sense to get the most out of it!

I would not be surprised that in a year or two years Sony will have this 70” inch LCD for around $15,000. Over time prices will come down. Some of the 100” to 108” LCD screens sale around $100,000. As demand increases for larger screens prices will fall.
