Yes, TI claims to have a 4K projector for the Cinema, but it weighs 250 pounds so is in a different category that the DLPs discussed in this article:

Oh, I always thought when they say "4K" resolution it refers to the horizontal pixel count.  i.e. 4096 x 2160 for 4K, not 4 million pixels in total.

Thats why i was surprised when I hear that TI suppplys 4K movie projector engines to the projector companies.  Do they really have DLP resolutions of 4096 x 2160?  or are they using some trickery to claim that resolution?

From Wikipedia:

The Digital Cinema Initiatives consortium established a standard resolution of 4096 pixels × 2160 lines (8.8 megapixels, aspect ratio ~17:9) for 4K film projection.

Yes, you are right, they have 4k Cinema chips (2560 x 1600).

Regarding wasted energy, its true those little mirrors heat up, but for the same reason, its also the only technology that can take as much light as you can give it.

Isn't 4K the highest resolution from TI?  I thought they used those in the newer cinema projectors.  Or are they doing some trickery to claim 4K resolution from a 2K chipset?

 

In any case DLP seems like a waste of energy, even with its improvements stated in the article it still dumps light compared to other technologies that produce light as needed.
