Been debating about purchasing a projector for a long time and just pulled the plug on the 1080ST. Couple of questions regarding setup that I'm hoping you can help me with.
1. I am thinking about a 100" diagonal screen. With the 1080ST mounted on the ceiling....does the center of the lens have to extend an inch below the top edge of the screen? So if the top edge of the screen surface (viewable area) is 5" from the ceiling would I mount that 1080ST so that the center of the lens is 6" from the ceiling?
vidkidd: The projector calculator at BenQ is very accurate. Give it a try. Pro Tip: the center of the lens needs to line up with the center of the screen.
2. Is there a decent ceiling mount that would give me the flexibility of adjusting this vertical distance from the ceiling? With my ceiling at 8" height and my center channel speaker at 2'10" from the floor the screen will take up most of the available area so I'm guessing the projector will be fairly close/flush mounted to the ceiling
vidkidd: There are many projector mounts every type of installation. After using the projector calculator, make sure you have some adjustment above and below the desired hight to dial in the perfect image. In my installation, I am using the UPM50 from PDR that I had initially used with a Sanyo PLV-Z3. Due to height adjustment needs, I had to install a mounting board between the studs to adjust the projectors image to the proper height.
3. Is there a trick to make sure the projector lens is plumb, i.e. perfectly parallel to the screen so I don't get focus issues? Is it best to mount the screen first and then the projector? Is there a ceiling mount that helps with yaw,pitch, rotation to get perfect focus on the screen?
vidkidd: Well... For my projector placement, I am set to the Largest image the projector can throw. (search my posts on AVS to see more). To adjust the Horizontal Rotation, I reduce the size of the image to a smaller size and use a tape measure for ensuring the image is equidistant from the sides of the screen.[/B]
4. When setting up the projector...should the zoom be set to minimum (1.0) or maximum (1.2) or centered (1.10) so I have some flexibility to adjust to screen size?
vidkidd: Set the Zoom so that the image is the LARGEST size it can throw. Then adjust the distance from the screen to dial in the size. If the Optics were better, this would not be an issue.[/B]
