Very good overall, there is the usual amount of light background noise that you can pick up in still scenes when standing close to the projector, but rarely noticeable during normal viewing. This is typical of DLP projectors.
The projector does a great job on handling potential jaggies, smooth as it gets on the flag test from the HQV disk. (Too bad, though, the 1080 version of the HQV test disk isn't out for another month or two), so the HQV tests are at 480, and are to complement visual observations from 480 an 1080 sources.
Of greater interest, the W10000 is very good on motion artifacts. it also does well most additional tests from the HQV test disk, although it does have some problems with some of the cadence tests (most projectors do, except, I guess the ones using HQV processing - funny about that).
Overall, I have see no issues with the static or motion image noise artifacts. Solid performance in this area.
