However, the CNET review specifically mentions that this projector uses "digital keystone correction" which is another way of saying in order to adjust the image so you're not looking at a trapezoidal rectangle, the projector uses a software solution and it introduces artifacts. Basically it introduces ugly noise around straight lines.
So as the reviewer put it, people wanting to put this projector on a coffee table are basically presented two unpleasant choices. Watch a trapezoidal image, or deal with the artifacts correcting it introduces.
I know the review you're speaking of, and he wasn't terribly clear on this point: placed correctly, on a stable surface and aimed at a wall or screen perpendicular to the lens, the W1080ST will produce a perfectly rectangular image. The keystone correction is only there if you can't
meet those requirements, same as any other projector that features it (which is pretty much all of them).
Now, the W1080ST can be more fiddly to place than a standard projector, just because the more extreme angle at which it's projecting is less forgiving of an uneven surface, but it's just plain false to say that using keystone is required. Careful placement eliminates the need for it, same as any other projector.
Farmhill, 1080p on a 120 inch screen looks just fine. Keep in mind that plenty of movies are still shot, finished and displayed theatrically in 2K, which is practically identical to 1080p. If you get close to the screen then sure, you'll see the pixels, but if you're sitting far enough back to actually take in the entire image, you won't. And the W1080ST will certainly be bright enough to light all of it, even in eco mode.
Speaking of which, in eco mode the lamp is rated for 6,000 hours, not 2,000. Hell, even in standard mode it's rated for 3,500.
