A big thanks to everyone who has contributed to this thread. As a new W1070 owner, I have learned a lot from the 65 pages I've read so far and my goal is to read it all.
I've temporarily placed the W1070 on a shelf until my mount arrives. Based on what I've learned, the center of the projector lens should be between the following heights:
minimum: [height of the top of the screen from the floor] + [actual screen height x 5%]
maximum: [height of the top of the screen from the floor] + [actual [screen height x 15%]
I'm using the minimum, with an EZframe Cinewhite 135" screen that is 66" in height, so I have the center of the projector lens placed 3.3" (66 x 5%) above the height of my actual screen.
I'm using the built in test pattern for alignment. The alignment looks pretty decent to me, with one exception. The bottom row of rectangles is noticeably shorter than in every other row, by at least 20%.
It looks like this...
(my screen is actually level horizontally, the pic makes it look a little skewed).
Using a graphics editor, I can see that every row of rectangles is 120px in height in this pic, except the bottom row, which is under 100px. And measuring it in real life the bottom row is noticeably shorter by about an inch.
I was just wondering if this is due to my amateur alignment skills? I just want to make sure it's not an issue with the projector.
If it is my alignment skills, any idea which way I should be moving the projector to fix it? I've been playing around with it, but the bottom row always seems to be shorter than the rest.
The other question I had was regarding the lines in the alignment image. Should it be my goal to make the outer lines just barely touch the black border, or make it so the lines bleed over a tiny bit onto the border?
Thanks for any insight that anyone can provide.
