Past 1080p: When?

[MouseRider]

As MPoozy has correctly stated, the Christie 2k projector is actually 2k lines horizontal instead of 2k vertical resolution.

For example, the Christie CP2000 Digital Cinema Projector, which uses the 2K 3-chip DMD DLP Cinema chipset is 2048x1080.

They now have the next generation of projectors that are 4K, I saw my first one 2 years ago at NAB from Sony, it uses SXRD technology and has 4K resolution, that means 4096x2160.

If you want full 3-chip 2K performance in your home, you can get it now with something like SIM2's HT5000. Of course it won't be as bright as a Christie and the optics are short throw and you won't have a D-Cinema source file.
