The Sharp XV-Z30000 3D DLP Video Projector will not be added to the list since it uses 3:2 pulldown for both 2-D and 3-D sources


The Sharp XV-Z30000 DLP 1080P Front Projector has a list price of $4,999. What is disappointing is that for a projector that lists for $4,999 it throws away the advantage of 24 fps for both 2-D and 3-D sources by adding 3:2 frame judder to all 1080p/24 signals including frame packed 3-D. Consumers can purchase a JVC DLA-X30 Front Projector at a list price of $3,500 that properly displays 2-D 1080p/24 signals at 96Hz (The JVC has a low refresh rate for 3-D which is one of its negatives).

The following quote is from pages 60 and 61 of the July 2012 Home Theater magazine review

“The Sharp refreshes at 120 hertz (60 Hz for each eye in 3D). In either 2D or 3D, the projector converts 24 fps (frames per second) sources – essentially all movies on Blu-ray – to 60 Hz by adding 3:2 pulldown. This isn’t the best approach, as it throws away the advantages of 24 fps (which avoids frame judder).”

Runco QuantumColor Q-650i 2-D LED-DLP Projector



(Home Theater magazine review link)



Flicker free Cinema quality 48Hz viewing with 1080p/24 2-D material



Runco Q-650i is the cheapest 2-D 1080P LED projector on the market ($10,000)


The Runco D-73d starting at $49,995 is the cheapest 3-D LED projector available for the consumer. For those consumers that are only interested in 2-D there is the Runco Q-650i single LED projector that has a much cheaper price of $10,000. The Runco Q-650i also properly displays 1080p/24 2-D signals at 48HZ with no flicker.


The following are select quotes from the Home Theater magazine review


“A DLP Frame Rate control provides four settings: Auto, 48 hertz, 50 Hz, and 60 Hz. Auto uses 2:2 pulldown to 48 Hz for Blu-ray movies at 24 frames per second (flashing each frame twice) and switches to 60 Hz on interlaced sources. I was concerned that 48 Hz for 24 fps sources would produce visible flicker, but I didn’t see any. If you do, you have the option of switching to 60 Hz, which performs 3:2 pulldown on 24 fps material for a higher refresh rate.”

But the Q-650i needs no color wheel. It performs the same function by sequential flashing of its multicolored LEDs. LEDs can operate at a much higher rate than any color wheel, which largely eliminates the problem. I can’t speak for those who may be even more sensitive than I am to this artifact, but it has always annoyed me. In the weeks I lived with the Runco, I didn’t see a single rainbow. The Q-650i is a DLP projector without tears.”

Panasonic TC-P55ST50 3D plasma Sound and Vision magazine review



“fairly serious level of image flicker generated by the 48-Hz setting makes it all but unusable.”


Every year Panasonic keeps coming out with plasma screens with an unusable 48Hz setting due to serious level of image flickering (according to Sound and Vision magazine and several other professional reviewers). Consumers to avoid the image flicker of 48Hz end up leaving their Panasonic plasmas in the default 60Hz mode. 60Hz has 3:2 pulldown judder during camera pans, etc. The top of the line VT series Panasonics also offers a 96HZ setting that is normally flicker free for most 2-D viewing. Panasonic should offer a 72Hz or 96Hz setting for their entire line of plasmas and consumers should not have to purchase the top of the line VT series in order to get Cinema quality frame rates without flicker (bright scenes sometimes has flicker at 96Hz according to a CNET review).

The entire line of 2011 and 2012 LG plasma screens offer Real Cinema 3:3 pulldown at 72Hz for 1080p/24 2-D material. LG plasma displays with the 72Hz feature range in price between $549.99-$2,399.99. Consumers that want to bypass the 3:2 pulldown method for 2-D should purchase a LG plasma screen. The Panasonic TV-P55ST50 has a list price of $1,600. For $1,799.99 the LG 60PM6700 3-D plasma will give consumers 5 inch bigger screen with true Real Cinema 3:3 pulldown at 72HZ when watching 1080p/24 2-D signals. When it comes to 3-D frame packed Blu-rays both the Panasonic and LG 3-D modes refresh 3-D signals at 120Hz (3:2 pulldown - 60Hz for each eye). All 3-D plasmas from LG, Samsung, and Panasonic use 100% active shutter glasses at the full 1080P resolution. Hopefully in the future one of those manufactories will make a 144fps plasma to match the Cinema 3-D frame rate instead of 120Hz with 3-2 pulldown for each eye.

Quote
“Another feature found on higher-end Pannys that’s missing from the ST50 line is a 96-Hz display option for watching 24p content on Blu-ray Disc. What you do get is the choice to display 24p with either a 60-Hz or 48-Hz refresh rate, although the fairly serious level of image flicker generated by the 48-Hz setting makes it all but unusable.”

Panasonic TC-P55ST50 Plasma 3D HDTV Home Theater magazine review



Home Theater magazine mentions a dimmer picture and visible flicker in the 48HZ mode



Every year its always the same story with the Pansasonic plasmas, no 72Hz or 96Hz mode on the lower cost Panasonic models, consumers have to purchase Panasonics top of the line VT series if they want to bypass both the flicker and 60Hz 3:2 pulldown issue. Another option for consumers is the LG plasmas. Every 720P and 1080P LG plasma from 2011 and 2012 offers a 72HZ mode for 1080p/24 2-D signals.

The following are select quotes from the Home Theater magazine review

There are 48 Hz and 60 Hz refresh rate options on the 24p Direct in control, but the 48 Hz position produces a dimmer picture and, depending on the program material, visible flicker. The 60 Hz setting eliminates both of these annoyances, but adds 3:2 pulldown to 24 fps material.”

The TC-P55ST50 disappointed me only in the smallest of ways. Specifically, it’s no Pioneer Kuro (RIP), but if you think it should be, you don’t get out much. Its video processing is good (see Video Test Bench) but doesn’t do too well on 2:2 sources—a common failure on many sets.”

Panasonic TC-P55ST50 3-D plasma CNET review link


Hopefully one day the entire line of Panasonic plasmas will offer a 72HZ or 96Hz mode for 1080p/24 2-D signals. Then 3-D should offer 144fps instead of 120fps.

Quote from CNET

As usual, I found the 48Hz mode flickered too much to be watchable.”

Panasonic TC-P55VT50 3-D plasma CNET review link



96Hz mode better handles 1080p/24 with slight flicker on some bright scenes



3-D has flicker when 120Hz (60Hz each eye) mode is switched to 96Hz (48Hz each eye) mode



No Cinema quality 144Hz or 192Hz 3-D mode


The Panasonic VT50 series is Panasonics top of the line consumer plasmas that have less flicker issues compared to Panasonics lower cost models like the ST and GT series. Still CNET mentions that the 60Hz mode is the only mode that is completely flicker free. In very bright areas of the screen for some reason according to CNET the 96Hz mode while watching 2-D material produced a slight flicker. Also in the 3-D mode switching from 60Hz each eye (120Hz total) to 48Hz each eye (96Hz total) greatly improved the crosstalk problem but then since the refresh rate is so low minor flicker could be seen.

The ideal future plasma screen from Panasonic should offer a flicker free mode at 72Hz or 96Hz for 2-D 1080p/24 material. Then also, the 3-D mode should offer a totally flicker free refresh rate of either 144Hz or 192Hz for frame packed Blu-ray discs.

The following are select quotes from the CNET review

“Panasonic also reserves its 96Hz refresh rate, designed to better handle1080p/24 sources, for the VT50 alone.”

“I did detect slight flicker in 96Hz in bright areas, for example the clouds over Brooklyn in "I Am Legend"

“In any case I still prefer the flicker-free 60Hz mode.”

The Samsung PN60E7000FF 1080P plasma screen will not be added to the list since it uses 3:2 pulldown for 3-D sources


The Samsung PN60E7000FF plasma screen according to the August 2012 Home Theater magazine review will properly display 2-D 1080p/24 signals at 96Hz when Cinema Smooth is turned on within the Film Mode control. The problem is the Samsung PN60E7000FF just like all 3-D flat panel screens currently in production offers no 144Hz total refresh rate (72Hz each eye) mode when playing back a film based frame packed Blu-ray 3-D disc. Instead the Samsung PN60E7000FF according to the Home Theater magazine review displays 3-D signals at 120Hz total refresh rate (each eye sees 60Hz 3:2 pulldown).

The following are select quotes from page 49 in the August 2012 Home Theater magazine review

“The PN60E7000FF refreshes at 60 hertz, 96 Hz, or 120 Hz. With a 24-fps, 2D source and Cinema Smooth selected in the Film Mode control, the refresh rate is 96 Hz, and 24 fps displays at four times its original refresh rate, with no 3:2 pulldown conversion. The added frames are merely repeated; Cinema Smooth is not a motion-interpolation feature. There’s a slight bit of motion blur on fast-moving objects, but no display is completely immune to this, and plasmas in general are better at suppressing it than most, If you’ve selected Cinema Smooth and feed the set a non 24-fps source, the refresh rate reverts to 60 Hz and one of the Auto Film Mode settings. However, 3D playback always uses 3:2 pulldown on 24-fps sources, for a total refresh rate of 120 Hz (60 Hz at each eye).”

Panasonic TC-P65VT50 3D Plasma HDTV (Home Theater magazine review link)


96Hz mode minimizes the Panasonic 1080p/24 flicker issue



No Cinema quality 144Hz or 192Hz 3-D mode


The 2008 60 inch Pioneer PRO-141FD according to the Home Theater magazine review still has the best overall 2-D picture quality and the deepest black levels when compared to the 2012 Panasonic TC-P65VT50 3D Plasma.


The following are select quotes from the Home Theater magazine review


“For 24-hertz source material, the set’s 24p Direct in control offers the choice of 96-Hz, 60-Hz, or 48-Hz refresh rates. Choose 96 Hz to minimize flicker. 60 Hz adds 3:2 pulldown, which may or may not produce motion judder (depending on your sensitivity to it). For 3D, the 96-Hz option is not available.”

“Why do we so often insist on comparing a set under review to an HDTV you can no longer buy? Because in the three years since the Pioneer Kuro departed the HDTV scene, there has not yet been another set that can equal or better it in all respects, most particularly in black level. Bringing that up may frustrate the reader, though it reminds manufacturers that they still have a way to go.”

The LG 55LM9600 3D LCD will not be added to the list since it only offers 540P for each eye and adds 60Hz 3:2 pulldown when in 3-D mode


Only 540P for each eye instead of 1080P for each eye when in 3-D mode

3-D 192Hz 8:8 pulldown mode adds 60Hz 3:2 pulldown for each eye prior to displaying the image on the screen


Only the Passive projectors on the list at the beginning of this thread offer true 1080P for each eye. The LG 55LM9600 like all other 3-D passive glasses LCD display only offers 1920 X 540P for each eye when a frame packed Blu-ray is the signal source. Also this LG LCD display adds 3:2 pulldown to both eyes when in 3-D mode prior to display. The LG has a 192Hz 8:8 pulldown mode for 3-D but since 3:2 pulldown 60Hz is added to each eye prior to display it defeats the purpose of the Cinema quality 192fps mode. The scanning backlight with Dark Frame Insertion simulates 480Hz, but the real native refresh rate of the LG 55LM9600 is 240Hz. 2-D 1080p/24 sources are displayed at 240Hz using the Cinema quality repeating frame method when Trumotion is turned off.


The following are select quotes from pages 39 and 42 in the September 2012 Home Theater magazine review


“This artifact may also be a by-product of the reduced vertical resolution in passive 3D. With active glasses and a 1080p Blu-ray 3D source, each eye sees a 1920 x 1080 image. With passive, each eye sees 1920 x 540.”

“The set’s native refresh rate is a maximum of 240 hertz, but it can simulate 480 Hz with a scan-ning backlight and Dark Frame Insertion. The LG raises 24-Hz 2D sources to the set’s refresh rate via either repeating (Trumotion off) or interpolating (TruMotion on) the added frames as necessary. However, in 3D, 24-Hz sources undergo 3:2 pulldown, converting them to 60 Hz prior to display. According to LG, the set employs 8:8 pulldown with 24-Hz 3D sources.”

The Sharp LC-90LE745U will not be added to the list since it uses 3:2 pulldown for 3-D sources


The discontinued 60 inch 2008 Pioneer Elite plasma models offer deeper blacks levels, better off axis performance, and overall better 2-D picture quality when compared to the 2012 Sharp LC-90LE745U. Even the 2011 70 inch Sharp Elite LCD screen with local dimming LED offers an overall better picture quality when compared to the 2012 Sharp LC-90LE745U. The Sharp LC-90LE745U uses full LED backlighting with limited global dimming. According to the Home Theater magazine review the Sharp LC-90LE745U has serious 3D crosstalk issues along with adding 3:2 pulldown judder to each eye when watching 3-D frame packed Blu-ray discs. The ideal flat screen display should unpack the frame packed Blu-ray movies at 48fps and then triple flash the image on the screen at 144fps (72fps each eye) or quad flash 192fps (96fps each eye). Currently only the front projectors on the list offer true Digital Cinema quality frame rates for both 2-D and 3-D.

The big advantage of the Sharp LC-90LE745U LCD screen is its size and price. With a list price of $11,000 and a retail street price of $10,000 it’s currently the cheapest and the only mass produced 90 inch LCD screen on the market. While the overall 2-D picture quality does not look as good as a 2008 60 inch Pioneer PRO-141FD, there was something special about seeing a screen size of 90 inches at the local Best Buy Magnolia store in my area. A 90 inch screen brings one closer to the home theater experience and it makes 60 inch displays appear to be small. One can sit as close as 9 feet from the 90 inch 1080P Sharp display and not see any noticeable artifacts.


The following are select word for word quotes from the Home Theater magazine review


“The native refresh rate is 120 hertz, but if you select the AquaMotion240 Motion Enhancement mode, the backlight cycles on and off to produce an effect similar to a native 240-Hz refresh rate. The set uses 3:2 pulldown to convert 1080p/24 3D sources to 1080p/60.”

“Awesome was the word that came to mind when I first laid eyes on the Sharp. There’s no question that such a big, bright image, viewed from 10 feet away, definitely grabs your eyeballs.”

Some 4K displays will not support the full 4K Cinema quality specs


The 84 inch Sony 4K LCD display with LED's for $24,999.99 will only display so called quad 3,840 x 2,160 4K images. The Sony VPL-VW1000ES 4K SXRD Front Projector for $25,000 is much better since it will also support 4096 X 2160 resolution. 4096 X 2160 is the full 4K Cinema quality specs and it is a disappointment that the 84 inch Sony 4K display is limited to 3,840 X 2,160 resolution. The 4K optical format will most likely not be released until around the year 2016. Until 4K optical discs become a reality consumers will be able to upconvert their 1920 X 1080P Blu-ray discs to 3,840 X 2,160 resolution. Then consumers that own the Sony VPL-VW1000ES will one day be able to view true 4096 X 2160 movies in theory if the new 4K optical format supports 4096 X 2160 resolution.

There are several 4K Digital cinema resolution and Pixel standards

LG 84 inch 4K LCD flat screen for $20,000 (3,840 x 2,160)


The LG 84inch 4K flat screen for $20,000 is the cheapest so called 4K flat screen on the market. Just like the Sony 4K 84 inch display the LG only supports 3,840 X 2,160 resolution and not the full 4096 X 2160 resolution. The LG currently can be used to upscale 1920 X 1080P Blu-ray discs to 3,840 X 2,160. Most likely around the year 2016 there will be a 4K optical disc format that will be released, but until then upscaled 1080P Blu-ray discs are what 4K displays will mainly be used for. YouTube does have a few 4K videos with resolutions up to 4096 x 3072 which is ideal for those that have high speed Verizon FIOS with download speeds up to 300Mbps.

JVC Expands 4K Projector Lineup for 2013

These new so called 4K JVC projectors are using e-Shift2 technology with 3 standard 1080p D-ILA chips instead of using native 4K panels. Also the JVC projectors are unable to display native 4K content.

SIM2 CINEMAQUATTRO 4K 3-Chip DLP Front Projector



** The first consumer 4K Front Projector to be added to the Cinema quality frame rate list **


** Flicker free 3-D performance using Cinema quality active shutter glasses at 144fps **


I have just added the SIM2 CINEMAQUATTRO 4K 3-Chip DLP projector to the list. This state of the art 4K projector contains a total of 3 DLP chips with each one having a resolution of 4096 x 2160. The SIM2 CINEMAQUATTRO will display 2-D 1080P and native 4K 24fps content at 48Hz. Also frame packed 3-D Blu-ray movies when unpacked by the SIM2 projector at 48fps will then be triple flashed on the screen at 144fps using active shutter glass technology for a flicker free Cinema quality 3-D experience. All 1080P 2-D and 3-D content will be upconverted to simulate 4K quality. Of course to take full advantage of this 4K projector one will need to wait until a 4096 x 2160 optical disc format is released (most likely around the year 2016).


Quotes:

Indianapolis, Indiana, USA—September 2012—SIM2 Multimedia is proud to announce at CEDIA EXPO 2012 our new CINEMAQUATTRO 4K DLP 3-Chip Home Cinema Projector. This powerful new model utilizes technology of Christie®, one of today’s leading display technology providers. Some of the key specifications are: three 4K (4096 x 2160) 1.38” DLP Chipsets, up to 20,000 ANSI Lumens, Triple Flash 3D Technology, SIM2 Exclusive High Contrast and Colorimetry Profiles, a user replaceable Xenon Bubble Lamp, remote monitoring and so much more.
When SIM2 decided to embark on the 4K challenge, it was clear that we had to offer a product with performance as close as possible to a true movie theater experience,” stated Maurizio Cini President and CEO of SIM2 Multimedia. “Our collaboration with Christie assures that our Premiere Dealers will have access to the BEST 4K technology available today, and not a product that is “just” good enough because it is 4K resolution.
Christie is very pleased to be working with a company of SIM2’s caliber,” said Jeff Jaramillo, Senior Director, Product Management at Christie. “Our companies complement each other well and the combination of technical and market experience certainly yield a high performance offering that delivers a stunning 4K option for the CEDIA community.

The Runco SC-50d and SC-60d 1080P Front Projectors will not be added to the list since they use 120Hz (60Hz for each eye in 3-D mode)


In my recently communication with Runco they informed me that the 1080P SC-50d and 1080P SC-60d are 3-D upgradable using active glasses. What is disappointing is that both the SC-50d and SC-60d use a total of 120Hz with 60Hz 3:2 pulldown judder for each eye when frame packed Blu-ray discs are viewed. There is no 144fps Cineam quality triple flash mode on the SC-50d or SC-60d.

The Runco D-73d Ultra 3D DLP Projector is state of the art



Never requires a new bulb since it is LED based




This amazing 3-D projector operates like a Digital IMAX 3-D system.




1080P/24 material is flashed on the screen at 24Hz with no flicker (no black time). A 48Hz 3-D signal is displayed at the same time (One projector displays left eye 24fps image and the other projector displays right eye 24fps image at the same time)



The passive glasses on the Runco offer full 1080P quality for each eye


There are now 3 Runco 1080P 3-D Front Projectors on the list.The Runco D-113d starting at $199,995 is Runco’s flagship 3-D 1080P projector that was introduced in 2011.The Runco D-73d has a base price of $49,995 and for $72,395 a Shasta CineWide lens with Autoscope is a option.


Runco now has a middle priced 3-D 1080P projector that is between the D-113d and D-73d. Its called the Runco D-73d Ultra.

Quote

“The D-73d Ultra has the same award-winning CSV 3D, 3Dimension processing and PreciseLight optical system, now in a longer throw distance for installation flexibility and best in class optical performance, designed for higher sharpness and lower color distortion.”

The following is a select quote from the April 2011 UltimateAVmag.com review on the standard Runco D-73d


(This quote also applies to the new Runco D-73d Ultra)



Movies were played at 1080p/24, and the D-73d displayed them at 24fps—according to Bob Williams, chief product architect and recent guest on my Home Theater Geeks podcast, this is exactly how digital-cinema projectors display movies, with no double or triple flashing as with film projectors.”

The Mitsubishi HC7800D 3D DLP Projector will not be added to the list since it does not have a 144fps Cinema quality triple flash 3-D setting


** No Cinema quality triple flash 144fps 3-D setting **


The Mitsubishi HC7800D 3D DLP projector will properly display 2-D material at 96Hz when a 1080p/24 signal is received if the Frame Rate Conversion control is set to off (frames are repeated instead of interpolated). What is disappointing is that the Mitsubishi HC7800D uses 96Hz (48Hz for each eye) instead of 144Hz (72Hz for each eye) when a frame packed 3-D Blu-ray movie is viewed. In the commercial movie theaters, a minimum of 144fps is used for single light source 3-D projectors to offer a flicker free 3-D experience.

Quote
“When the Frame Rate Conversion control is set to True Film or off, 24-fps sources are displayed at a refresh rate of 96 hertz (48 Hz per eye for 3D). In True Video, the 2D refresh rate is 120 Hz. In the off position of Frame Rate Conversion, the added frames are simply repeated. In the True Film or True Video settings, the added frames are interpolated. The F.R.C. Level control, just below Frame Rate Conversion in the Advanced menu, offers five levels of interpolation, from minimum (1) to maximum (5). Longtime readers know I don’t usually like motion interpolation for the video-like sheen it imparts. But the interpolation on the Mitsubishi worked better than most, and with some material, even including films, I found it useful—in its lowest setting”

What LCD TV with an IPS panel gives the best motion for 24fps 2D content?

Plasmas handle motion the best with excellent response times. I like the motion quality on the 70 inch and 60 inch 120Hz Sharp Elite LCD that also use full LED backlit local dimming for deep black levels. When it comes to LCD screens 240Hz and 480Hz models normally offer the best motion. Turing off frame interpolation on 480Hz, 240Hz, and 120Hz LCD displays produces a film like 24P quality motion. The IPS panel technology you mentioned is a technology that was developed by Hitachi in 1996. Samsung Electronics introduced a technology called PLS (Plane to Line Switching) which they claim is a improvement in image quality compared to IPS technology.

Higher Frame Rates


Joe Kane at Widescreen Review magazine wrote a very interesting article about frame rates. In a dual light source projector setup like one finds in a dual Christie DC2K IMAX configuration each eye sees 24fps with no flicker since there is no black time. Also it’s possible to run a single light source 3 chip DLP projector at only 1fps or 1 frame every 10 minutes and there will not be any flicker on the screen. The reason single light source 3 chip DLP projectors double flash at 48fps or triple flash at 72fps for native 2-D 24fps material is because the motion quality is poor at lower frame rates when using a single projector configuration. So higher frame rates offer better motion quality especially when using a single projector setup. We live in a complicated world with engineers creating all kinds of different display technologies. It all depends on the display technology being used. Single chip DLP projectors need to double flash at 48fps for 24fps 2-D material and triple flash at 144fps for 3-D 48fps material in order to offer a flicker free performance (the more light output offered by the projector or display also means the higher the frame rate needs to be to get rid of flicker. At 120Hz for 3-D material most people do not see a flicker but the problem is each eye sees 3:2 pulldown judder). While some high-end 3 chip DLP projectors with a single light source have no flicker at 1 frame every 10 minutes they still need to display 24fps 2-D materiel at 48fps or 72fps in order to offer good quality motion.

The following are select quotes from Joe Kane’s article in the September 2012 Widescreen Review magazine (full article is located on pages 42, 44, 46, and 47)

“I’d like to start with DLP technology, as it is still my favorite way of displaying images. The DLP is a parallel imager and is always on. The image isn’t scanned. The entire image is displayed on the DMD at once. There is no noticeable period of being off between one frame and the next.”

“If you had a three-chip DLP projector you could drive it at 24 fps, or 12 fps, or 1 fps, or 1 frame per minute, or 1 frame in 10 minutes, and you wouldn’t see flicker. Yes, you might notice the motion capability wasn’t good at these lower rates, but they would have a light on all the time instead of the flicker of many other types of displays.”
