Anyone know what happens to the image other than it expanding obviously when you slide the projector away from the screen perpendicularly. Does the image stay centered and just get bigger or does it also transit vertically?

I think it does rise vertically. I read somewhere you take the screen height x .24 to get the distance from the P1's stand height to the bottom of the screen. You can round it down to the nearest inch because of the adjustable feet.

No it doesn't stay centered, bottom of the image only moves vertically a few inches while the rest of it expands or gets smaller

Pricing on the LS 500

Pricing on the LS 500 - the 100-inch projector and screen combo will cost $4,999, while the 120-inch combo will be $5,999, and both include a pair of 10-watt front-facing speakers. I'm not sure about the pricing without the screen.

Pricing with screen is ok, but they killed their product by not making it a real UST

Okay, thanks, makes sense... seems like the ANSI contrast rating is generally much harder to find than it is for lumens w/r/t projectors .

Anyway, if this UST projector from Optoma has a native ANSI contrast of 500:1... which happens to be the same as my dated HT1085ST DLP projector, should I expect similar contrast between the two?

If so, that would be majorly disappointing.

How big a factor does dynamic dimming make and is it safe to assume that isn't factored in to the ANSI contrast (alternatively, how much of a difference would the perceived contrast differ between two projectors with the same native contrast but much different dynamic contrast ratings)? I see that native contrast is definitely more important, but still not clear how to compare and contrast (...) the ratings.

I guess the crux of what I'm asking is "has contrast performance generally stalled for projectors in the last 5 years or has it improved significantly despite the same native contrast ratings"? Trying to decide if I can make the plunge now w/ the P1 or wait another year for affordable 0.66" DMD ST/UST offerings to start showing up.

In my experience contrast numbers are meaningless in specs, wait until reviews come out and do a real measurement.

Yep from a reliable 3 party also. Not the dealer lol. Not that the review from the dealer isnt welcomed it's just unusable for evaluation and purchase.

Okay, specific projector contrast ratings aside, can I be a bit more general and just ask how the perceived contrast on mid-range laser projectors of today (IE: UST options that have been released like the WEMAX/VAVA/etc) compare to older budget DLP bulb projectors 5 years ago (IE: BenQ/Optoma) given the same native contrast.

I'm trying to get a sense of if this is something that has been getting significantly better using other methods of implementation or if it's mostly been stagnant and the contrast on those older bulb projectors are more or less in line with newer laser projectors.

I can tell you that I owned this one https://www.projectorcentral.com/Acer-H6510BD.htm before I got Xiaomi and spec numbers aside perceived contrast as well as blacks and color is much better with laser UST. Also both projectors are native 1080p, but 4k looks so much better with Xiaomi. I would expect that Optoma won't let us down with P1 and it will be as good or better.

Btw where did you see native contrast 500:1 for P1?

Appears to be determined by the DMD it's using.

The problem remains that the native contrast of the 0.47" Digital Micromirror Device (DMD) is around 500:1 which is a far cry from the native contrast / black levels you get from an OLED Screen or JVC front projector (several thousands: 1).
The larger 0.66" DMD has provided a native contrast of 1,000:1 and Vivitek will be using that DMD in its UST projector expected later this year (probably showcased at CES in January).
^ although I think I had read one of the Xiaomi projectors was able to get over 1000:1 with the .47 somehow.

I've attached my hand written notes. It's best to use it as a guide. The Only thing I would change is the depth of the Center Speaker base/platform from 15 inches to 12 inches to account for cables sticking out and other variances. I'll be cutting 3 inches into mine where the projector sits. I didn't have the screen up when I made the measurments. Rookie mistake ;-)

Awesome thanks!!! What size is your screen right now
120inch?

Over 2,000:1 actually according to the French review: https://www.passionhomecinema.fr/blo...is-de-gregory/ (English translation further down). But since it should be impossible to get a native contrast significantly ecxeeding 500:1 with the 0.47" DMD, it has been speculated that the Xiaomi already uses dynamic laser dimming in the standard operation mode without having announced that.

I was just told this by my Optoma rep a couple of minutes ago.



My belief if that they want to make sure they all updated with most current firmware and ready to be released as "bulletproof" considering that they have a big campaign out there to compensate people to leave reviews for the projector online.



It is possible that the date could change again, but this is where we are at as of today.


Any updates on ship date? I noticed that projector screen.com says 9/30.

NP! Yes 120 inch. It's the biggest size you can currently get with PET CLR.

and they claimed 3000:1 native contrast which again shows how these numbers in specs don't mean anything along with a lumen rating.

Eastporters in Canada has a package with the cinemax pi and Aurora 8k ust alr screen 120 inch for $5400. Looks like an amazing deal for the screen. Does anyone know if the quality of the screen is similar to xy pet crystal? The frame and material look the same, both are.8 gain.

See a copy of the email I received from Eastporters

Here is a link to the screen: https://www.eastporters.com/product/110-elunevision-reference-8k-short-throw-alr-projection-screen-2/ We currently do not have a package price up on our website! Yes that price is for a 120" fixed frame. The screen gain is .08 gain. If you have any questions please let us know!

For those in Europe interested by the European model (UHZ65UST). I've just chat with optoma France and they told me the UHZ65UST and P1 are different model, the UHZ65UST have 3500 lumens and 2 500 000:1 contrast ratio ( the P1 one have 3000 lumens and 1 500 000:1), they finally set an MSRP price of 3.299 € for France (It certainly should be the same elsewhere in europe)

I'm curious if this is true. Here in Germany they advertise it with 3200 Lumens and 3995Euro (including VAT)

They told me they just changed the price to 3299 Euros MSRP who was before announced at 3999 Euros MSRP. For the lumens I found that strange too, you can see their reply on twitter ( https://twitter.com/OptomaFrance/sta...59606365208576 ), they announced it for October but nothing precise yet.

That would be great news if the decide to lower the price and raise the lumens! I'm really looking forward to the release.
Thanks for the information.


Maybe I should follow the french Optoma page instead of the german.

Good idea . "Heimkinoraum" in Germany is still stuck on 3.999 EUR and I already left a comment on their board about the announcement of their French colleagues. Lets see what happens...

Expected to ship out next week; it depends what time they arrive on Thursday or Friday to then be shipped out to customers.
