It means a horizontal resolution for the TV of about 4000 (in the TV world, I believe it is actually 3840x2160...referred to as 2160p). This compares with the horizontal resolutions of 1080p HDTVs that is 1920.
The net result is that you end up with a TV that has about 4 times the resolution of a 1080p HDTV.

It's extremely confusing terminology. We're going from an exact number representing vertical resolution (1080p) to an approximate number representing horizontal resolution (4k).
I'm also extremely skeptical about this having any real value in a home environment--at least if you don't have a front projector and a really huge screen. And even then...
First of all, 2K looks terrific on a giant screen. Most movie theaters have 2K digital projectors these days, and they look excellent. And a great many theaters (perhaps most) that have 4k projectors never remove their 3D lenses, which effectively turn them into 2K projectors.
I doubt that the average person, watching average content, would notice the difference on a 65-inch screen.
And speaking of content, that's the other issue. There isn't any--at least not yet. Sure, the TV manufacturers are going to include some content in the TV itself, but that will be limited and possibly not what you want to see.
In the long run, I may be wrong. But in the here and now, 4k TVs are worthwhile only for people suffering from TMM (Too Much Money).

Unless you have the projector more than ten feet away, yeilding a larger than 75 inch image, you'd be hard pressed to see any difference. I see it as a spec of selling point that few will understand and fewer ever realize the difference. I've found that even an average size set, around 32 inch, the source and connections between them and all equipment, will make or break any setup. Properly adjusting the display to suit the source format will give the best results without having to use any added conversion options such as stretch and zoom. Letterboxes can help to get the contrast adjusted with a supposed "black" border. All that processing naturally gives you a higher price, almost three times a top end 1080p set.
