    Hello,

    I have recently set up (or almost finished, anyways) a HT setup that includes a BenQ PB6100 projector, which I have mounted on the ceiling (upside down), about 6.5 feet from the floor, about 12 feet from the screen.

    My question(s) is/are:
    Is it normal for the projector itself to be at an angle in order to project the image roughly 3.5 feet up the wall? Is this a shortcoming of an admittedly low-buget projector? It seems to me that the projector needs to be at an unusually steep angle (tilted way down at the back in order to get the image where I want it).

    Am I missing something here?

    Thanks for any help!

    Paul

    Is this projector meant to be put on a coffee table when being used? This may result in what looks like an unusual mounting angle for ceiling mounting. See if there are optical or physical adjustments for moving the picture or lens up or down without moving the body of the projector.

    Normally a video projector is mounted even with the top of the screen or the bottom of the screen. There may be exceptions, check your projector manual. Then you should be able to find the best combination of projector itself upside down or rightside up, and menu selection for image upside down or rightside up.

    The more upscale projectors have "keystone correcton" which allows more steep tilts without ending up with a trapezoid (distorted) picture.

    Maybe you could have a pole coming down from the ceiling for the projector mount so the projector is at the proper height for the screen.

    Paul, that is normal for that model. I checked into that model, but bought the X1 instead. Your projector has a large "image offset". This means the image is so many inches below lens when ceiling mounted, or so many inches above lens when table mounted. You have to use keystone correction to correct shape of image after you angle projector.

    Thanks,

    When doing my research I clearly neglected to consider this in my comparisons...not a big deal, though...other than this, I find the Benq to be quite capable for the price range.

    Cheers,

    Paul
