I tried to put a paper in front of the projection and it was there. I dont know how to explain, it is like dithering/shimmering. It is not present always, only on some backgrounds, where there is a lot of dark content/colors? I added a wallpaper where the shimmer is visible. I need to stand close to the screen (around 0.2-0.3m) to notice it, it is not visible from my 3.2m viewing distance. Would be great if someone with W1070/W1080ST could put this wallpaper as desktop background and inspect from up close. Could this be normal image noise? From reading DLP projectors have image noise/mosquito noise, could this be the phenomenon i am experiencing? I read few reviews and wonder if this sparkling that i notice on some colors (most of the shimmering is on dark colors, it looks like film grain on the spots where it occurs?) is image noise? For example on a review of W1080ST the reviewer writes: There’s always noise, it’s just that the W1080ST seems to have a touch less. - See more at: http://www.projectorreviews.com/benq...e/#image-noise
Could this be the phenomenon i am experiencing? Or is it something else? it is not visible from 1.5-2+ meters, just from up close, with head on the projected image. On bright colors and backgrounds there is much less of this issue, maybe up to 5percent of the total projection, but on dark colors and backgrounds as is the wallpaper i attached it is visible much more. Ofcourse nobody watches anything on PJ from 0.2m, but as i say, it is something i noticed while walking past the projection screen and wonder if it is a defect or is just normal image noise. This is also my third W1070, the first one had rattling fan, second one didnt focus well(couldnt get focus in the middle and at the same time in one corner, could only do a compromise between the two), third one doesnt have rattle, focuses pretty good(one corner is not 100percent sharp, but it is ok, and i cant expect 100percent sharpness on all the corners and middle at this price point, i think? could hear ur opinion about this also), but... there is one transparent circular spot @ the pure black screen, maybe a dust inside the lenses, anyway it is almost invisible even on pure black screen.
I'd really like to settle down with exchanging the PJs and just enjoy what it gives, its just i dont know now if this ,,shimmering'' is normal phenomenon or a defect and if i should return the unit.
Thank you very much for hearing me and supporting me in this matter.
I added a video of this also. Don't mind the ,,blinking'' and rainbows that my phone pick up, they are not visible IRL, only the ,,sparkling/shimmering'' from up close. Here is the link for the video: https://vid.me/fmtq
