I absolutely LOVE BenQ projectors. Theyre my go to choice. The quality is great, the image is fast and I can play PS4 and PC/Movies comfortably on them and the short throw is a MUST. But my W1080ST suffers from the same problem as the W710ST...it has DUST BEHIND THE LENS! This makes the picture very unenjoyable... Theres black fuzzy blotches all over the screen. The closed design is supposed to stop this, but it actually makes it an unfixabke nightmare! I live in a near dust free home, and I use air purifiers all over, and this STILL captures dust/dirt.
And the 3D is nearly impossible to turn on...if used PS3s, PCs, 1.4a HDMI Blurays and this projector refused to recognize that it can even do 3D! Ive got it to work twice!
But other than that, this is a fantaatic projector, and it will amaze you. I just hope BenQ notices this comment and fixes it!
