If I win one I plan to use it as an analog clock in my kitchen. I'm talking 22 inches of digital analog emulation. Seems like a good use to me.

It's not "the new Ultra HD", it's Digital Cinema 4k, which is 4096 x 2160, or roughly the equivalent of a 2 by 2 matrix of 1080p displays (and exactly the resolution of a 2 by 2 matrix of Digital Cinema 2k displays).

See the following illustration for clarification:

It is interesting that they should call it "highest resolution panel of its size", as I don't know of many 20.8" monitors!

That being said, I do know of the IBM T221/Viewsonic VP2290B. They are based on the same panel, which is a '22.2" inch wide (16:10) LCD monitor with 9.2 million pixels arranged in stunning 3840x2400 (QUXGA-W) resolution, contrast ratio of 400:1, brightness of 235 cd/m2, and viewing angle beyond 85 deg in all directions'

I don't think there are any $2K 1080p projectors on the market. However, for $8K+ your point is 100% valid. I would much rather spend my money on a good Projector, Screen, and Scaler ("Line Doubler").
