Hisense PX3-PRO and the C2 portable long throw

[Robert Zohn]

We had a great time with Hisense's execs and engineers discussing the advancement of all of their new 2024 portable long throw and UST projectors that will all be 3D capable and use active 3D glasses. We took them on a tour of our new suite of 16 Cinema demo rooms.

We will be the 1st US dealer to get the new 2024 PRO-3!

Robert thanks for the information. I normally in my posts start with the negative first and then do the positive. The Hisense PX3-Pro like 99% of all consumer DLP projectors does not have a native 4K DLP light engine but instead uses a 2K light engine with pixel shifting technology to simulate 4K quality. Hopefully one day at least one or two higher end Hisense projectors will use a true 4K DMD imaging chip and of course the first generation might cost $30,000+ but would be cheaper than the current $80,000+ models from various companies.

On some very positive news the Hisense PX-3 Pro spec sheet shows it uses Polarized 3D which uses low lost passive glasses technology instead of the active glasses technology. According to Roberts post for the year 2024 all of the Hisense projectors that are long throw and Ultra Short Throw will be 100% passive glasses. That is a incredible achievement since it is hard to find a 2K DLP projector under $20,000 that uses passive glasses, they all use active glasses under $20,000. The way other brands do it is they can take a 4K DLP projector and offer true 4K resolution to each eye using passive glasses for the $80,000+ models and for around $25,000-$30,000+ on the 2K DLP projector setups with passive glasses. With Hisense offering DLP projectors like the PX3-Pro for $3,500 that supports passive glasses that is the cheapest DLP projector on the market that can do that. The $80,000 Sony LCOS projector along with all JVC projectors are active glasses only. While both active and passive glasses on a DLP projector have the exact same picture quality at 144fps. The advantage of passive glasses is they are cheaper and no battery to charge, but the projector needs to be brighter for passive glasses and sometimes a special screen is need for 3D projection.

Most likely Hisense passive 3D glasses technology does not offer near 4K resolution for each eye like other much more expensive DLP projectors and to save money each eye sees 2K (1080P). But since the year 2010 Blu-ray 3D format is a native 2K (1080P/24) format for each eye that is fine if Hisense cannot do 4K 3D since there is no consumer 4K 3D source material. Hopefully when the Hisense projector sees a frame packed 48fps signal (1080p/24fps) for each eye, that hopefully the projectors use 144fps triple flash technology that is flicker free for 100% of the population. Since 96fps results in around 50% of the population seeing a flicker on DLP projectors. So hopefully 144fps triple flash is used on all the new Hisense projectors (not mentioned in the spec sheet).

But real cool consumers in 2024 are finally getting low cost 1080P 3D from a DLP projector using passive glasses. Very hard to find passive glasses on consumer DLP projectors. I wish Sony and JVC would offer passive glasses on their LCOS projectors. I wish Epson and others would offer passive glasses on their LCD projectors. No longer will consumers need to have to pay $25,000+ for a passive glasses DLP projector setup, but instead Hisense will deliver passive glasses from DLP projectors for $3,500 in the third quarter of 2024.

Another amazing thing about the Hisense PX-3 Pro laser DLP projector is that according to the spec sheet one gets both Dolby Vision HDR and HDR10+ from the same projector. Dolby Vision HDR is currently exclusive to DLP projectors and is not offered on LCOS projectors or LCD projectors (at least not yet).

The Hisense PX-3 Pro is also IMAX Enhanced for HDR. One part of Imax Enhanced is a certification process and guidelines for HDR so that it looks correctly.

Quote

“We'll see IMAX Enhanced versions of films and documentaries that should look far better than the original versions, according to IMAX. This is thanks to IMAX's proprietary post-production process, which uses an algorithm to bring out the sharpest, highest-quality 4K HDR images with reduced levels of noise and graininess.”

“They claim that without this process, HDR content can actually look worse than the filmmakers intended due to raised levels of noise and graininess.”

To be able to do 4k 3D they will have to implement a new codec (MV-HEVC) similar to what apple did to the vision pro. I am patiently waiting to see who will be the first to make a move on this, most likely on an 8k projector to help boost it.

@Robert Zohn what is the reasoning for Hisense to try passive 3D other than saving a few bucks on the cost of glasses but adding extra components to its projector to be able to achieve this and then making it a little more costly to the consumer and since every other UST including awol which is pretty much a clone of a hisense is active 3D. active today on UST's has no crosstalk (ghosting) and i don't see much benefit on passive now to be a sales pitch (also the screen has to be a different kind for passive or they found a magical solution for this as well).

[Robert Zohn]

Some of the reasons Hisense designed the new PX3-PRO with Passive Polarized 3D technology are:

1.) Higher frame rate vs. active shutter 3D glasses. So the images are flicker free.

2.) Moderately brighter 3D image performance vs. active shutter 3D glasses.

3.) No battery to charge so Passive 3D glasses are always ready to use.

4.) Passive 3D glasses weigh less and are more comfortable.

5.) Passive 3D glasses cost much less for consumers to purchase.

6.) Passive 3D glasses reject the images between the left and right eye views to eliminate ghosting issues in the 3D videos.

7.) All passive 3D glasses work on all passive 3D displays. So if you have 3D glasses that came from a commercial movie theater they will work on Hisense's new 2024 UST and portable long throw projectors.

Thanks Robert. i will wait and see once a professional reviewer gets one properly calibrated and do some comparisons, i still think this will be dimmer than the actives i.e awol 3500 due to less lumens and the nexigo aurora pro (with 2400 lumens which is closer to what the PX3-PRO will be), i want to see how contrast will fair with washed dark grey looking blacks on a passive equipment.

So that means they’re using some version of a circular polarizer to allow the use of passive glasses. I’ll be very curious to see what their silver screen offerings are priced at.

Robert a DLP projector in the commercial movie theater can do 144fps (72fps for each eye) using active or passive glasses and they offer the same flicker free 3D quality without ghosting. The reason why 90% to 95% of the commercial movie theaters use passive glasses instead of active glasses is because of the huge cost difference plus the battery recharge issue. In a few small commercial theaters in the world the consumer has to make a $30 to $50 deposit on the active glasses to make sure they are returned, where as passive glasses purchased in bulk only costs $2 each. Even high-end passive glasses costs $20 versus $100+ for high end active glasses.

This Hisense projector is most likely using 144fps triple flash technology since that is the only single DLP projector frame rate that is 100% flicker free for over 8 billion people in the world. Now 96fps using passive and active glasses produces a small flicker that 50% of the world population can see.

The spec sheet needs to be updated to mention 144fps triple flash technology with passive glasses. That is a feature found on $30,000+ 2K DLP projectors.
This Hisense projector will be ideal for people that watch around 90% Blu-ray 3D which is native 2K (1080P). However if one watches 90% 4K Blu-ray and 4K streaming then a JVC or Sony LCOS projector starting at $6,000+ would be better because of the native 4K light engine.

Since Hisense comes with a silver screen for Blu-ray 3D it was a smart decision for the company to go 100% passive polarized glasses. Whereas people with older higher-end DLP projector setups that want to go passive 3D have to replace their screen with a silver screen.

DLP projectors, LCOS projectors, and LCD projector engineers if they do not want to make their future projectors to work with a silver screen, can instead use Dolby 3D that does not require any special silver screen, Dolby 3D uses ones existing standard screen since low cost color filtered glasses are being used in commercial movie theaters with Dolby 3D. Sometimes on some Dolby 3D systems head movement might be limited when compared to REAL3D that uses polarized glasses. REAL3D, IMAX, and Dolby Cinema all use polarized glasses with silver screens. Most commercial theaters are polarized glasses, with a few theaters using Dolby 3D so that they can use the exact same screen.

[dooblehorn]

I am surprised (and shocked) that Hisense is making anything that supports 3D! I bought a Hisense UST laser TV with included 120" screen and am very happy with it. Except it does not do 3D. I also own almost every 3D movie available. That said, I have an active 3D DLP projector and a passive 3D LG TV. I love that TV, and love the passive 3D but bought the projector for when the LG TV finally dies. The passive 3D of this new Hisense will likely make me replace my current Hisense, but will probably not happen until well after it's released and the price drops. But am wondering if you can still watch non-3d on that silver screen? That would be a deal-breaker for me if you cannot.

[HDTV1080P]

Silver screens work with all projectors and all video formats including 2D and 3D. A silver screen just uses highly reflective material which results in offering more light then a white screen. Silver screens produce brighter images and sometimes higher contrast ranges and are ideal for passive 3D glasses and also standard 2D without glasses. When IMAX and Dolby Cinema theaters show a mixture of 2D and 3D material in the same theater, they use the exact same screen (same is true for home theater projectors). But silver screens are not perfect and sometimes are brighter in the center when compared to a white screen. There are positives and negatives for both white screens and silver screens. If one has a 50,000 to 100,000+ lumens output projector a silver screen would not be needed and a white screen should work fine. It’s the low lumens output projectors that need a silver screen. Of course if one is watching their projector outdoors in the yard during a bright day then a silver screen is ideal with a 100,000+ lumens output projector. There are positives and negatives for both white projector screens and silver projector screens.

[dooblehorn]

Thanks, HDTV1080P, this is great info, thanks!

[BLMN]

it needs to be seen in action first, the brightness (peak brightness once measured will most likely be a little lower than 3000 lumens) and low contrast for blacks vs how it will look on a silver screen will be a deciding factor. I am not a fan of this type of passive technology anyways, i hate the cheapness of the glasses and how it looks in cinemas (RealD 3D) and ive been working with commercial grade christie projectors with RealD 3D modules for about 7 years and still don't like them, now if this was the same polarized version that imax dual laser and dolby cinema uses (and the glasses don't look and feel cheap) than it would definitely be a game changer.

[HDTV1080P]

Real 3D and other 3D technologies in the theater that use a single Christie DLP projector use triple flash technology and take the 48fps 3D image (24fps right eye and 24fps left eye) and flash it on the screen at 144fps (72fps for each eye) that results in no flicker and no ghosting. However if money is no object, then dual Christie DLP projectors is the best way to do 3D, also dual DLP projectors are needed for high quality Dolby Vision HDR. In IMAX and Dolby Cinema theater there is no need to use triple flash technology and the 48fps 3D image is displayed at 24fps for each eye (left eye 24fps and right eye 24fps image). High frame rate 3D with dual projectors work the same way no need to triple flash, if the native 3D image is 60fps each eye sees 30fps (30fps left eye and 30fps right eye). 96fps 3D is 48fps for each eye.

Once Hisense successfully releases all new DLP projectors both long throw and short throw that use 144fps triple flash technology with passive glasses for the legacy year 2010 Blu-ray 3D format. The next really cool option I would like from a consumer DLP projector is the ability to place two exact same models of Hisense projectors in a dual projector harness to offer double the brightness for better quality Dolby Vison HDR/HDR10+ and also better quality 3D. If there was a mode in the Hisense projector to connect two projectors at once like a IMAX and Dolby Cinema Christe projectors that would be the best quality. Maybe the Hisense imaging chip could not offer native 24fps for each eye but if it could do 48fps for each eye without using triple flash technology that would be one of the best consumer DLP projectors on the market.

So the ideal Hisense projector should work as a single projector at 144fps triple flash for 3D and then 24fps or 48fps for 2D mode (Only Christie projectors can do flicker free 24fps output). Then if the consumer purchases two exact same Hisense projectors for a IMAX and Dolby Cinema setup a external dual projector processor box from Hisense would link the two projectors together to offer double the lumis output for 2D Dolby Vision HDR and 3D at either 24fps or 48fps for each eye with no need to triple flash for the passive glasses.

The high-end consumer videophiles and professional installers would embrace Hisense or any other DLP company that allows a dual projector setup similar to Christie. I would love to buy two DLP projectors for the home for a IMAX/Dolby Cinema style setup. Consumers wanting something cheaper would just buy one DLP projector with the option to buy a second DLP projector a few years later if they want better performance. Stacking two long throw or two short throw projectors together is possible side by side or with a custom enclosure. Just some ideals.

[HDTV1080P]

In the ideal world in the year 2026+ a 8K optical disc format should be released that supports 2D at 8K and 3D at 8K. However If 3D at 8K is too expensive then the new 8K optical disc format could do 3D at 4K and 2D at 8K along with legacy support for all resolutions between 480i to 8K when it comes to downscaling or upscaling.

But for 3D technology to take off a new 8K optical disc format needs to be released with mandatory 4K 3D or 8K 3D in the specs. Then also 3D 4K or 8K streaming and broadcast would be ideal. For now Hisense and other projector companies can capture market share from all the existing millions of Blu-ray 3D owners that have a 2K 3D collection. But long term the next physical and/or streaming format needs to support either 8K or 4K 3D streaming. Native 3D movies at 4K quality exist in the commercial movie theater, so logically that needs to one day occur at home. The BDA could mandate all new 8K Blu-ray players needing to offer frame packed 4K 3D in the specs for 2026+. Also there are some technologies better then frame packed technologies when it comes to 3D. So using a native 3D technology instead of legacy frame packed might be ideal.

Just some ideals.

[Robert Zohn]

At CES 2024 Hisense and AWOL demonstrated two of their new projectors positioned next to each-other to render stunning 21:9 aspect ratio images.

Hisense used their C1 Portable long throw projectors.



AWOL setup their LST-3500 Pro UST projectors.

[HDTV1080P]

Placing two low cost DLP projectors in the home side by side starts at under $10,000 and runs to over $600,000+ for the higher end dual projectors.

IMAX and Dolby Cinema projectors with native 4K 3D start at half a million dollars since two $250,000-$300,000+ projectors need to be used. IMAX theaters run from $2 million dollars to $25 million dollars. With the average IMAX theater costing $5 million dollars. Some newer Dolby Cinema theaters are better quality when compared to an older 10-year-old IMAX theater. However sometimes a modern IMAX theater is the same or better then some older Dolby Cinema theaters. Dolby Cinema tickets can sometimes be 25% higher in cost then a IMAX theater in order to pay for the latest technology.

Robert since you have contact with the Hisense executives and engineers. If you could please forward this link to them regarding product improvement for flat panel screens, that would be awesome. While DLP projectors are better than flat panel screens, some people that live in a apartment, condo, or certain rooms in a home might not be able to mount a screen on the wall and might need a flat panel screen instead sitting on a TV cabinet.

@HDTV1080P, thank you for all of your excellent and helpful posts! You have excellent technical knowledge!

Specifically I appreciate the content you wrote on the link you listed at the bottom of your above post! Everyone should read it and I'll pass it along to the engineers. However, I am sorry to say I do not expect we'll see the Hz/frame rate increase as this would be a serious hardware and firmware upgrades and the current processors and display modules are not easily upgraded as you so well and properly recommended. Also to achieve your luxury and technically very well designed would be very costly. But you definitely viewed the future of digital video display technology.

My connections at Hisense are with the UST division where we are factory direct and well connected with management and engineering.

I seem to make these relationships with all major video brands.

My successful professional engineering background and our annual TV and UST and Long Throw Projector Shootout® Evaluation events draws much attention thanks to all of the large and very positive media coverage.
