4000 lumen, WUXGA (1920x1200) laser projector with 3D.

This would probably make a great living room projector and/or a nice giant computer monitor.
It's nice that laser models are getting out and maybe Benq will transfer it to the HC area, but the HZ39HDR is probably about the same brightness, and has more features. And cheaper.
The Benq has a slightly shorter throw, but not sure what it brings over the Optoma.

Where are the high power units with a rgbrgbg wheel?
It seems that laser projectors can use RGBY CWs and still get a wide colour gamut with higher brightness. Of course some are optimized for higher brightness over a wider gamut.

Which laser DLP's have a wide gamut? Isn't most(all?) with smaller than rec709 gamuts?

The stock UHZ65 can do about ~110% of Rec709. With the filter it gets close to 100% of DCI-P3.
That sounds right, the uhz65 natively has a bit more green, but red is bt709 max. Here's the typical spectrum of blue laser yellow phosphor, you can see you'd have to cut alot of light to get more saturated red.


there's still the issue of color brightness with the 4x rgby wheel as well. Same thing, you have to cut alot of light output to bring those color lumens up. I wonder if they started with a rgbrgbg wheel a second color filter may not be needed, or maybe a rgbcym wheel with a color filter? It almost can't be helped at this point due to the OEMs are all designed for presentation use and not home video.

Very ready for to start seeing rgb laser come down in price. 1500 lumens(@300-400w) at 100% bt2020 with 100% color brightness, drastically reduced RBE, color wheel flicker eliminated, solarizations eliminated, perfect motion, perfect color depth. If they use dmds with at least 2000:1 native contrast they can have 10,000:1 near artifact free dimming, with all that brightness and intense color performance you'll have a really fantastic image for home video.

The above uses a single laser, but multi laser designs such as this:

can easily exceed DCI-P3.
I wouldn't call 110% of rec709 wide, but its better than I thought.

Waiting for rgb lasers myself, I know that they can do real wide gamut.

Hefty green saturation on the Mijia, but red is not so great, so that won't be able to do 100% p3.

Look at the chiq c8ut, that can pretty much hit bt2020

The Mijia though, I hadn't read that review yet, 2000 calibrated lumens of rgb laser dlp for $1,000, even if it is using a phosphor for green. That's fantastic. That's use a 0.25 gain black screen level of light output. This can do 3d also? I might pick one of those up just to see.

According to the review the ALPD3.0 can hit 114.1% of P3.

If you look at the cie chart youll see it has a higher saturation of green than the p3 target, but lower red. The red p3 target is about halfway from the what the projector can do and bt2020.

Its fantastic performance though and especially for the price.
