JVC DLA-X70R April 2012 Home Theater magazine review

The JVC DLA-X90R and DLA-X70R does not qualify to be added to the 3-D list since the frame rate is below Digital Cinema 3-D projectors

The JVC DLA-X90R and DLA-X70R offer simulated 4K quality

On the positive side, the latest JVC Front Projectors have excellent black levels for a consumer Front Projector. Only a Pioneer Kuro and Sharp Elite flat screen according to the Home Theater magazine review offer more impressive black levels.

The new JVC DLA-X90R for $12,000 and the JVC DLA-X70R for $8,000 will properly display 2-D 1080P/24 signals at 96Hz using a 4:4 pulldown repeating frame method. These projectors offer simulated 4K quality since they will not accept native 4K source material (Possible in 4 years or so a 4K optical format might launch). What is disappointing is that the new JVC Front Projectors Clear Motion Drive is limited to a maximum of 120HZ. The modern JVC Front Projectors just like last year’s models display Blu-ray 1080P 3-D frame packed movies at a total refresh rate of 96Hz (48Hz for each eye). 48Hz for each eye is a low refresh rate for 3-D.

In the commercial movie theaters 100% of all single light source projectors use a minimum of 144fps (72fps for each eye) to offer a flicker free high quality 3-D experience.

I am hoping that maybe one day on future JVC models the Clear Motion Drive might be upgraded in order to offer triple flash 3-D technology (144fps) or quad flash 3-D technology (192fps).

The following are select quotes from the April 2012 Home Theater magazine review (review located on pages 50-54)

“For 2D sources, the projector operates at a refresh rate of either 120 hertz or 96 Hz, depending on the source frame rate, 96 Hz is used for 24-frames-per-second 3D sources (48 Hz foe each eye).”

“JVC simultaneously launched a range of more affordable models that will not accept 4K source but seek to provide the key benefits of 4K projection by using 2K imaging chips in a creative 4K simulation.”

“The projectors’ maximum input resolution is 1920 X 1080, so it will not accept a native 4K source…”

“The quality of the black levels and shadow detail won’t surprise anyone who’s been following past reviews of JVC projectors. The only displays I know of that produce more impressive blacks are the now departed Pioneer Kuro plasmas and the new Sharp Elites.”

“Still, viewers bothered by the low brightness levels of 3D may want to consider either a smaller screen, one with a higher gain, or perhaps both. But that’s good advice for any relatively affordable 3D projector.”

REDRAY 4K PROJECTOR for under $10,000 might be released in 2012

It would be excellent if this 4K REDRAY projector were released this year. It would be $15,000 cheaper compared to the $25,000 Sony VPL-VW1000ES 4K consumer projector. Also consumer 3-D 1080P projectors that use passive glasses technology currently cost $50,000-$200,000+. At $10,000 the 4K REDRAY projector would be a bargain by offering true 1080P (or 2K) quality 3-D with passive glasses (2-D material is displayed at 4K quality).

The only negative with the REDRAY projector is that it would add 3:2 pulldown judder for both eyes when 3-D is shown at 120fps. All single light source projectors in the movie theater use 144fps in order to offer a flicker free presentation without 3:2 pulldown judder issues during camera pans.

Sony VPL-VW1000ES 4K SXRD 3D Projector: Take 2

Lower cost 3-D Front Projectors under $50,000 still do not offer the Digital Cinema frame rates and brightness quality when viewing 3-D source material. This Sony VPL-VW1000ES at a price of $25,000 is the cheapest consumer 4K projector on the market and is ideal for those that want good quality standard 2-D quality projection of movies. Maybe in 4 years or so consumer 4K optical disc source material might be availbe to feed 4K projectors.

The following are select quotes from part two of the Home Theater magazine review.

“This means the 3D brightness level was about 8 percent of the level possible in 2D in High lamp mode (even though the default 3D settings pushed the projector harder than the 2D settings). The results did not differ significantly in any of the three picture modes.”

“The visible results confirmed these measurements; 3D was not very rewarding with this setup. After five or ten minutes, I was ready to return to the VPL-VW1000’s gloriously bright, vivid 2D. But while 2D and 4K are the Sony’s calling card, most buyers are likely to expect a satisfying 3D image at this price.”

“If you’re shopping in this price range for a new projector, the Sony VPL-VW1000 should definitely be on your short list. If 3D is not an important target on your radar, that’s all you need to know. If you’re big on 3D, you need to accept the fact that most home-theater projectors today, including this one, really won’t light up a really big, low-gain screen with a bright 3D image. But if the VPL-VW1000 were my choice, I’d definitely be a two screen kinda guy—a big, modest-gain or 1.0-gain screen for 2D and a smaller, high-gain screen for those less-frequent 3D showings. If I had the spare change, the VPL-VW1000 and two such screens would definitely be at the top of my list.”

JVC DLA-X30 3D LCOS FRONT PROJECTOR (Home Theater magazine review)

The JVC DLA-X30 does not qualify to be added to the 3-D list since the frame rate is below Digital Cinema 3-D projectors

For $3,500 list price the JVC DLA-X30 is an amazing bargain for those only interested in 2-D viewing. The JVC DLA-X30 2-D picture quality outperforms many projectors that cost double the price. When a native 2-D 1080P/24 signal is received the JVC front projectors will repeat each frame 4 times and display the 1080P image at 96HZ which maintains the original 2-D film quality.

What is disappointing is that the new JVC Front Projectors Clear Motion Drive is limited to a maximum of 120HZ. The modern JVC Front Projectors just like last year’s models display Blu-ray 1080P 3-D frame packed movies at a total refresh rate of 96Hz (48Hz for each eye). 48Hz for each eye is a low refresh rate for 3-D.

In the commercial movie theaters 100% of all single light source projectors use a minimum of 144fps (72fps for each eye) to offer a flicker free high quality 3-D experience.

I am hoping that maybe one day on future JVC models the Clear Motion Drive might be upgraded in order to offer triple flash 3-D technology (144fps) or quad flash 3-D technology (192fps).

The following are select quotes from the Home Theater magazine review

“The 2D picture from the JVC DLA-X30 is truly without peer among the immediate competitors we’ve seen. Its contrast and dynamic range continue to set the bar across all performance levels. The X30 was also the sharpest projector I’ve seen at this price, and was even better than most of the projectors I’ve seen at nearly twice the cost. But I was disappointed with the 3D performance. I admit I’m not a fan of the technology as a whole, as I feel it impedes the theatrical experience, but the X30 showed more artifacts in playback that further degraded the already gimmicky experience. If 3D is your primary motivator for a new projector, I would look to some other offerings on the market. But if 2D is what you find yourself watching the majority of the time (as I certainly do), this one would be hard to beat at or near this price point, and gets my highest recommendation.”

Lower cost 90 inches and larger flat screens might replace front projectors in the future

Sharp LC-90LE745U 90 inch LED LCD for under $10,000 at Best Buy

On Monday June 18th 2012 I stopped in my local Best Buy which has a Magnolia section. To my surprise there was a new Sharp 90 inch LCD with LED backlighting on display. The Sharp LC-90LE745U black levels and overall picture quality did not look as good as a 2008 model Pioneer PRO-141FD 60 inch 1080P plasma. Still there was something special about seeing a screen size of 90 inches. 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 a 90 inch 1080P Sharp display and not see any noticeable artifacts. This Sharp 90 inch screen only consumes 138 watts of power and with a list price of only $10,999. In fact Best Buy is selling it for $9,999 which is a breakthrough price for a flat screen of this size. It was not too many years ago that 70 inch flat screens cost $20,000-$30,000 (Now Walmart and Target have 70 inch Sharp flat screens between $2,298-$2,499.99). Consumers can get a 90 inch flat screen for under $10,000. A 92 inch Mitsubishi WD-92840 rear projector can be purchased from an Amazon dealer for only $2,849 (3:2 pulldown judder for 1080p/24). Of course most consumers do not like rear projectors because of their weight and large depth. Still if someone wants a cheap 92 inch 1080P screen Mitsubishi is the only consumer electronics manufactory that is still making rear projectors.

There is something special with watching movies at home on a large screen like 90 inches or over 100 inches. Some high-end ceiling mounted front projectors can project images as big as 150-300+ inches but most consumers do not have a big enough home theater room for a 300 inch screen. Between 90 inches to 130 inches is the limit to what most people can fit in their home theater room unless developers start building bigger houses with huge home theater rooms.


The advantage of a ceiling mounted front projector like the JVC DLA-X30 is that they cost under $3,500 and have outstanding black levels. Also the JVC DLA-X30 ceiling mounted projector is around 3 times cheaper compared to the Sharp LC-90LE745U 90 inch flat screen. The disadvantage of front projectors is that a dark room is needed for viewing and the advantage of flat LCD screens is the lights can be on for causal local news watching during the day.

As 90 inches and 100+ inch flat screens become more available we should start to see several for under $10,000 in the future as long as inflation does not increase too much. Possible 90 inch flat screens within 5 years might be under $5,000. There is a possibility that one day Front Projectors could disappear within a decade or so if large 100+ inch flat screens become very cheap.

The ideal flat screen in the far future would be an 8K or 4K 100 inch OLED that is as thin as a pencil. Possible several decades from now a 16K screen that is around 150+ inches and as thin as a poster could become a reality (it might even roll up like a poster for shipping and storage).

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.”

“Conclusions
You can get slightly better black levels and shadow detail with a few competing (and even cheaper) lamp-based projectors. They will also be bright enough to light up a larger, modest-gain screen in a way this Runco can’t. And they’ll likely offer 3D to boot. But none of them will provide better color or crisper detail than the Q-650i. Nor will they offer the freedom from concerns about gradual lamp deterioration."

"You’ll never have to worry after 1,000 hours or so if your picture has somehow gone south, prompting the need to write a check for a new lamp and another for a fresh calibration. In fact, the 650i doesn’t even have a amp timer. I expect that LED-based consumer projectors will eventually offer higher brightness and cost less. But that will be a gradual process, one that is sure to be slowed significantly by the requirements of 3D home projection, which is none too bright even with a lamp behind the lens. But for now, the Q-650i is the most affordable 2D LED projection game in town, and I enjoyed every minute I spent with it.”

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.

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 48Hz mode did introduce very minor flicker in the brightest sections of the image, but in my opinion that's a small price to pay for greatly reduced crosstalk. That flicker was quite a bit more subtle than what I saw in 2D using the 96Hz and 48Hz modes, and in 3D it didn't detract from my enjoyment of the film much at all.”

“Both the 60Hz and the 96Hz mode handled 1080p/24 sources properly in my test, and this year I didn't notice any extra false-contouring artifacts when setting the TV in 96Hz mode.”

“Blacks on the VT50 had an inky quality visibly superior to what I saw on any other TV in the lineup aside from the two Elites.”

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.”

“Blacks and shadow detail approaching reference quality”

“The luminance controls produced no significant change, but a recent call to the ISF indicates that a firmware fix to correct this is in the works.”

“And the Sharp Elite is still the black-level champ among currently available sets. (Some commentators have also taken the Sharp Elite to task for its cyan tracking—the location of the cyan point at various brightness levels. This is something that we did catch in our review but in any case never found distracting in normal viewing.)”

“While the Sharp Elite was not on hand for a direct comparison, my 60-inch Pioneer Kuro PRO141FD was. The darkest scenes on the Panasonic weren’t quite as enticingly rich, a result confirmed by the two sets’ measured black levels (0.001 foot-lamberts on the Kuro after three years of use; 0.002 ft-L on the Panasonic after an estimated 200 hours of operation). But keeping in mind that this Kuro’s MSRP (the top model in the Kuro lineup) was roughly twice the list price of the TC-P65VT50, Panasonic’s achievement here shouldn’t be underestimated. On Harry Potter and the Deathly Hallows Part 2, a film with more than its fair share of dimly lit, challenging video, the Panasonic held its own. The main difference between the two sets was a slightly smoother transition into the darkest region of the brightness range on the Pioneer. The Panasonic had a trace of black crush on a few shots; the Pioneer did not. But it was a very close call. The Panasonic looked very slightly sharper than the Pioneer, but that too was very material dependent.”

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.”

“With some material I did feel that the picture was a little less achingly crisp than with a comparably priced projector and screen (or even one of the better, considerably less expensive choices, such as JVC’s $3,500 DLA-X30).”

“But two issues kept the Sharp from earning a perfect score. The most obvious, and expected, was its off-axis performance. The colors at the extreme side of the screen fade noticeably if your seat is near the opposite edge.”

“The second issue is black level and shadow detail.”

“Conclusions
Yes, the off-axis concerns remain, but that’s a generic issue with all LCD sets to one degree or another. And if you want state-of-the-art black level and shadow detail (not just measured, but visible), this may not be your display. Furthermore, short of a fix for the crosstalk, fans of 3D might want to look elsewhere. But even with these caveats, there’s no denying that the Sharp LC90LE745U provides something rare indeed in today’s flat-panel market: a true projection-size home theater experience, without the projector.”
