I just installed the Cinegray 3d designer cut 135 inches diagonal yesterday on my diy frame. I'm fairly please with the screen, but there does appear to be some issues with it.
1. The material does have some vertical lines that do impair the picture. While I don't find these vertical lines objectionable in general, they create shading problems on the screen. For example, there is a noticeable vertical line toward the left third of the screen. If I sit on the right side of my couch, the image to the left of the vertical line appears slightly dimmer. If I then sit on the left of my couch, then the image appears dimmer to the right of the vertical line. If I sit in the center, the image is dimmer on the left side of the vertical line.
It's like these vertical lines create a slight shadow. I also notice this in the bottom middle of my screen where I think I may have pulled the material too tight. You can see a slight crease the frame makes in the material. Anything below this mark is considerably dimmer. It all fades out where the crease disappears.
Does anyone have any insight to any of this?
1. Did I make my screen too tight vertically that the center bottom portion of the frame is noticeable. Should I loosen the material a bit in the bottom middle?
2. The vertical creases that span the material. There's no way I could have tightened this material any further without ripping it. Will they go away in time or is this something I have to live with? I thought I read somewhere this seems all too common.
