ACER H78650BD: the DLP 0.66 chip counterattack and that's good.

DLP manufacturers seem to have understood that Texas Instrument's DMD 0.47″ chip was synonymous with a drop in quality for home cinema video projection (bright frame, disastrous contrast, etc...). It is therefore a new generation of front diffusers equipped with the 0.66 XPR X2 simulation chip that will arrive at Acer and Vivitek to begin with (I have no doubt that the other supporters of the fringe of micro mirrors will join this movement). It must make it possible to reinforce the contrast and precision of the image while being spared from the lack of light pollution (clear frame surrounding the image).

It is Acer who opens the ball, from September 2019, by marketing the H7850BD. A home cinema projector at the price of 1699€ which takes the shells of the H7850/M550 and V7850.
I already know that Vivitek will propose a similar model before the end of the year.

But let's go back to the H7850BD which offers a brightness of 3000 lumens (2400 in eco mode.) perfect for the playback of 4K HDR programs. Its HDMI 2.0 jacks are MHL & HDCP 2.2 compatible. Its video processing includes an "accumulation" image interpolation device and its optical compartment is equipped with a vertical Lens-shift (+ / - 15% manual).

Interesting... 3000/2400 Lumen with RGBRGB Color wheel? What about 3D?

As per the article it will support 3D

Sent from my Pixel 3 using Tapatalk

"The projection ratio is 1.39 ~ 2.22: 1 (1.805) and its 1.6x zoom combined with the mechanical shift of the optics must be put in place in your projection room. Finally, it should be noted that despite its 0.66 chip, it is 3D compatible. At its next release, I will not fail to offer you his test."

It sounds like an updated M550 or H7850.

TBPH I was kind of getting worried about Vivitek and consider this to be good news.

3D support sounds great; hope there is a U.S. version of this as well.

I want to see a new projector with this new larger chip using laser. An updated version of the Optoma UHZ65.

I'm not sure we are talking about a new or improved 0.66" DMD. My impression thus far is that the latest 0.66" DMD now supports 3D and that the native contrast of the 0.66" DMD was/is better than the one provided by the 0.47" DMD.


But I wonder whether thanks to dynamic laser dimming (supposedly much better than traditional lamp bulb dimming) - yielding better contrast levels - the native contrast differences between the 0.66" and the 0.47" DMD will remain visible or not.
