I have had a BenQ W1070 projector since early 2015 and have noticed an issue during 3D BluRay playback. 2D playback is not affected. I cannot be sure whether this is something that has only relatively recently started happening or whether it's always been there and now I've seen it I can’t unsee it. A friend couldn't initially see what I was referring to, so it is quite subtle.
It's difficult to describe but essentially what I am seeing is like a band, or strip, at the top of the image, which is very slightly darker than the rest of the image. In fact it is so subtle I am not entirely sure it is darker as such, but just different in some way. It is almost as if the top portion of the image is at a slightly different brightness setting, but not otherwise distorted. It is only visible in certain scenes and how noticeable it is depends on the scene. I haven't been able to ascertain precisely when it appears but the darker, or greyer, the scene, the more likely it is that you will see this band. It doesn't come and go as such; if it's present in a scene it will always be present in that scene and if it's not (e.g. in a bright / colourful / daylight scene) then it will never be there.
I am projecting onto a 106 inch screen and the band is probably about four inches thick and runs the entire top length of the image. If the aspect ratio is any wider than 16:9, such that there are black bars above and below the image, so covering the area that would otherwise be affected, the issue does not arise (or is at least not visible).
I've recently started watching a lot of 3D content and would like to get the issue resolved. I just don't have a clue what could be causing it. It's not a player issue (I have tried my PS3, PS4, Panasonic BluRay player and the issue occurs in each case). Might it be an HDMI cable issue? I don't currently have a spare HDMI that is long enough for me to test this, but I had thought that an HDMI cable either worked or it didn't, so a faulty cable wouldn't be the likely cause. It's not an issue with the 3D glasses because you can see it without the glasses as well.
Any thoughts gratefully received!
