Displays that support 1080p/24 signal at multiplies of the original frame rate

[HDTV1080P]

The NuVision NVU52DCM LCD TV and other NuVision LCD flat panel models will not be added to the list

The high-end NuVision LCD screens are listed in the specs as having a vertical refresh rate between 48HZ-72HZ but when a 1080P/24 signal is applied they refresh the signal at 60HZ using a 3:2 pulldown method. There is no benefit to 1080P/24 when 3:2 pulldown is used. Currently only one rear projector from Nuvision is on the list since it is known to display 1080P/24 on the screen at 72HZ similar to a film projector in the theater.

Quote
“Another feature that is largely—but not entirely—wasted is this set's ability to accept a 1080p/24 signal. Why is it wasted? Because the NuVision displays such a signal at 60Hz, which means the video processor applies 3:2 pulldown, repeating one frame three times, the next frame twice, the next frame three times, and so on, thus losing the benefit of 24 frames per second.”

When Pioneer offers the 1080P/24 feature they always bypass the 3:2 pulldown process and refresh the signal correctly at multiplies of the original frame. In the specs the Pioneer PDP-5000EX is listed as accepting 1080P but it does not mention if it supports both 1080P/60 and 1080P/24. I do not have access to the Pioneer PDP-5000EX to see if it accepts 1080P/24.

** Important update to the main list **

The main purpose of this list is to provide an easy to use reference tool for those considering to purchasing a new 1080P display that offers true film quality 1080P/24 refresh rates. In order to make the list more useful and accurate I have created 3 separate lists.

List number 1: Will only list the current in production or coming soon true 1080P/24 displays that have a documented manufactories spec sheet, instruction manual, or professional review that mentions the multiplies of the 24fps feature. Now people searching for a new display can view just the current in production or coming soon models.

List number 2: Below the first list is the second list which contains all the discontinued true 1080P/24 displays. On this list one can search the Internet or retail stores for new or used bargain prices on clearance displays that offer true 24fps refresh rates.

List number 3: This list which is below list number 2 contains 1080P displays that are pending to be added to list number 1 or 2. The manufactories spec sheet or professional review is not available yet that documents the true 1080P/24 feature.

Remember these 3 lists are not 100% accurate and items can be removed or added as more information is learned about a display. The most accurate displays on the list will be the ones that have professional reviews written when the link is clicked on.

This list only contains US models since all the reviews and publications I subscribe to are US magazines and newsletters. Anyone that would like to create a seperate list that includes 1080P/24 models for the entire world is welcome.
The United Kingdom TH-42PZ85B display appears to be in some ways similar to the United States TH-42PZ85U.

Mitsubishi HC6000 LCD front projector

In the June 2008 Sound and Vision magazine on page 62 and 63 there is a detailed review on this front projector. On page 62 it mentions the following quote:
“The HC6000 will also accept a 24p input from a Blu-ray Disc player, automatically frame-doubling the signal to a 48P display”

[HDTV1080P]

JVC DLA-RS1 and DLA-RS2 LCOS Front Projectors have been added to the list

The JVC Front projectors are some of the best Front Projectors on the market with excellent black levels and contrast ratio’s. All of JVC’s LCOS Front projectors refresh 1080P/24 sources at 96HZ and 60HZ signals are refreshed at 120HZ.

The DLA-HD1 and DLA-RS1 is almost exactly the same projector.
Quote
“According to the company, they differ in only two ways. The RS1 is sold through JVC's professional channels, and the HD1 is sold through consumer outlets. In addition, the HD1 is black and silver (see photo) and the RD1 is all black. But with respect to features, performance, and price, the projectors are identical.”

The DLA-HD100 and DLA-RS2 is almost exactly the same projector.
Quote
“Priced at $8000, the next-gen DLA-HD100 has an identical twin in the DLA-RS2, which differs only in that it is distributed through professional rather than consumer channels. The match between these models is even closer than between the DLA-HD1 and RS1 (the pro version of the HD1). I will refer only to the HD100 in the remainder of this review since that's the model I looked at. But all comments should apply equally to the RS2.”

Review on Samsung LN52A650 (5:5 120HZ LCD display)

The Samsung 650 series web link on the main list has been updated to include the CNET review. The Samsung LCD display will refresh 1080P/24 material at 120HZ using true 5:5 pulldown when Auto Motion Plus is turned off. When AMP is off each 24fps frame is repeated 5X times until 120HZ is reached.
Just because this set and other LCD screens on the list do true 5:5 pulldown it does not mean they perform the pulldown perfectly. In the CNET review the reviewer could not tell the difference between 1080P/24 and 1080P/60 with the source material they were using on both Sony and Samsung 120HZ LCD displays. If one watches a lot of BLU-RAY movies on a high-end JVC or Sony LCOS Front Projector or a Pioneer Plasma screen one can see the difference in fast moving scenes and camera panning shots. The judder is greatly reduced on some displays and the image has a more film like quality compared to smooth 60HZ video.
Displays that do true 48HZ, 72HZ, 96HZ, and 120HZ refresh rates are not all created equal. The specs on paper might look good but in reality some displays do to response time limitations or other reasons do not perform good in real world performance. A good 48HZ LCD Front Projector, 48HZ DLP Front projector, and 96HZ LCOS Front projector many times reduces the judder better then a 120HZ LCD flat panel screen.
To some this 1080P/24 and 1080P/60 feature is a minor feature since most of us all have been watching 60HZ 3:2 pulldown for most of our lives. I have seen the film like quality that good 1080P/24 displays have and I prefer it too displays that do not offer that feature. This feature is so important that the BLU-RAY format places 24fps on all film based BLU-RAY discs. Many professional videotape sources are also 1080P/24. When one is in the market to purchase a new 1080P display it makes since to get a display that handles 1080P/24 correctly.

Quote from CNET review

"We also turned AMP off, along with the Sony's de-judder processing, and switched our PS3 to 1080p/24 mode. We really couldn't tell the difference between 1080p/24 and 1080p/60 on either of the sets, so we suspect they don't perform the perfect 5x conversion from 24 frames to 120. Samsung's engineers (along with Sony's) claim the 52LN650 can perform this conversion, but if so, it doesn't make much difference.”

The following Sony LCD screens have been moved from list number 1 to list number 3 for further verification

In a prior news release it was mentioned that the Sony KDL-XBR6 series had Motion Enhancer technology with 120HZ. It appears that the specs have changed before the product was released. According to Sony’s instruction manual’s motion Enhancer and 120HZ is not even an option offered on the new Sony’s. The following displays might still have 120HZ but it is not mentioned in the instruction manual. It does mention Cinemotion feature which perhaps might refresh 1080P/24 at 48HZ or 120HZ. The tread in electronics seems to be moving toward the Walmart society where the goal is to eliminate expensive nice features in order to offer a product that is lower cost to purchase. Hopefully Sony did not drop 120HZ from the following new models in order to offer a cheaper price product. 120HZ is needed to reduce motion blur on LCD. Some companies were planning on coming out with 240HZ LCD’s that even greatly improve on LCD motion blur. If 240HZ LCD’s make it to market it will be interesting to see if they can start to out perform Plasma screens in some areas.

Now located on list number 3 pending a review or official spec sheet

Sony KDL-37XBR6 (1080P/24 might be refreshed correctly with Cinemotion)
Sony KDL-32XBR6 (1080P/24 might be refreshed correctly with Cinemotion)

[Gennew]

I got the KDL-40W4100 this past Sat and it does have 120HZ as an option. Its all over the box, it was on Best Buy's website, and it's on the stickers that came with the TV. When I was researching a new TV I wanted a TV that accepted a 24p signal and had 120HZ processing. The manual is for the 32" and 37" XBR6, the V series, and W series and it states that Motion Enhancer IS ONLY available on the W series. I've used the feature and can confirm it is on the W series 40" and up.

Sony KDL-52XBR4 review in June 2008 Home Theater magazine

For those interested in the Sony XBR4 and XBR5 LCD flat panel screens there is a review on the KDL-52XBR4 on page 74-76 in the June 2008 Home Theater magazine.

Highlights from the review regarding 1080P/24

Quote
“If you turn the Motion Enhancer off, each frame is simply repeated as many times needed to get 120HZ, with no interpolation”
So yes the Sony XBR4’s and Sony XBR5’s properly refresh 1080P/24 similar to a film projector in the movie theater.

Some negative and positives of having motionflow turned on
Quote
“More and more LCD HDTV’s are designing to operate at 120HZ. When done correctly, 120 HZ operation can minimize motion blur, an ongoing issue with LCD (but, in my opinion, not a deal breaker on most recent designs). “
“Motionflow is Sony’s name for its 120 Hz technology, and it works as advertised. It can smooth motion in a starling fashion. But it can also make a 24-frame-per-second, film based source look like video. This can be jarring, particularly to a film purist. If you must use this feature, I recommend you stick to the standard setting and engage it only on video-based programming, such as sports. Avoid it on movies.”

So motion enhancer (motion flow) can improve the picture on some 60HZ video programs, but at the cost of adding artifacts to the picture once and a while. Motion Enhancer should be turned off when watching 1080P/24 BLU-RAY’s if one wants the image to look closer to film quality instead of a smooth 60HZ video quality.

Marantz VP-11S2 DLP Front Projector (Has been added to the list) (48HZ refresh)

In the June 2008 issue (#132) of Widescreen review magazine there is a very detailed in depth 6 page review on the Marantz VP-11S2 DLP Front Projector starting on page 20. Of course ultra high-end 3 chip DLP projectors are better quality but they cost much more then this $15,000 single chip DLP projector. Widescreen Review is claiming this new single chip DLP is the best DLP front projector they have every reviewed.

Highlights from the review
Quote
“The Marantz VP-11S2 is a new 1080P DLP Front Projector that replaces the previous VP-11S1 flagship projector.”
“The Marantz VP-11S2 1080P DLP front projector is the first projector I have reviewed with Texas instruments new DC4 DLP technology. It produced the highest full-field contrast ratio I have measured from a DLP projector, and justifies the price premium over its sibling, the VP-15S1. “
“Plus the VP-11S2 will display “pixel-perfect” 1080P/24 native video from an HD-DVD or BLU-RAY Disc player without adding motion judder.”
“The VP-11S2 has an adjustable (4X, 5X, 6X) speed, seven-segment color wheel.”

1080P/24 feature with 48HZ refresh brief highlights (page 28 quotes)

The review has 2 long paragraphs regarding this frame rate conversion. Here are some brief highlights from the review.

“Video frame rates used for 24P film sources are normally 23.976(24/1.001) Hz, which the projector frame doubles at 47.952 Hz. Occasionally, sources produce rates that are exactly 60Hz or 24 Hz, although that is not common and not recommended. The auto 2 mode displays at 60Hz, 50Hz, and 48 Hz to provide compatibility with those signals (24HZ signals are frame doubled to 48HZ).”

Basically the review mentions that there are two auto modes and one manual mode for frame rate conversion so it offers the greatest compatibility with just about any player or source that is connected to the display.

3-D 4K Cinema and maybe one day home 3-D 1080P BLU-RAY movies

Beginning on page 58 of the June 2008 Widescreen review magazine is part 1 of how 3-D Cinema technology works. What is interesting about this review is that currently the new 3-D technology only works with DLP technology which is used in 97% of Digital cinema’s. .

Qoute
“ However, DLP is not the only projector technology approved for use in digital cinemas. Sony’s SXRD’s LCOS technology, with 4K resolution (4096 X 2160) is also out there, although on comparatively few screens. Sadly, Sony’s current 4K projectors are not capable of single-projector 3D, but the company says it’s working on it.”

I do not know if 3-D will every take off in home cinema. I am sure if it becomes really popular in theaters that over a 10 year period consumers would start purchasing new 1080P 3-D capable displays with 3-D BLU-RAY movies. I would like to see good quality 3-D technology become popular then perhaps one day all movies will be produced in 3-D. It could be 20 before all movies are produced in 3-D. It all depends on how fast the technology takes off.
If 3-D does become popular at home I might create another list called “3-D displays that proper refresh 1080P at multiplies of the original frame since the frame rate works differently when watching a 3-D movie.

This is a interesting quote from Widescreen Review to read about the frame rate for 3-D projectors

“The solution is the same in both cases: flash (refresh) the images multiple times during each frame period. The minimum is twice per frame, giving 48 flashes per second.” A standard film projector does this using a double-bladed shutter. For a digital 3-D projector, 48 flashes per second for each eye are accomplished by using left-right-right sequences during each frame period, resulting in a total of 96 images per second.”
“However a good number of people can still see flicker with 48 flashes per second. That’s just as true, by the way film as it is for digital projection, but screen illumination levels for the former are usually much lower (which is to say, most film screens are seriously under illuminated!). The brighter the image, the higher the refresh rate at which you can still detect flicker. The solution is to triple flash, producing 72 flashes per second. A film projector requires a triple-bladed shutter to do that, which is uncommon. In digital 3-D projector, left-eye and right-eye images alternate three times during every frame period, for a total of 144 images per second.”

To reduce or eliminate the flicker in film the refresh rate needs to keep increasing. As screen brightness keeps increasing on displays we are going to need faster refresh rates one day like 10:10 pulldown 240HZ or higher.
