    If you sit 10 feet away from a screen what is the maximum 16:9 screen you should be looking at without being uncomfortable.

    Thanks

    It depends on the quality of the picture. If you can't see the scan lines - maybe 15 feet wide?

    10 feet is about 3M.

    I would say a screen about 100~110" (diagonally) should be good.

    I'm using 106" 16:9 screen and I sit about 3.5M away from the screen. Looks BIG and comfortable.

    Very roughly you should sit 1.5 times the screen width away.


    That's a calculation. the other would ruin the furniture:clown:

    It also depends on the projector technology being used. You don't really want to get closer than 2xscreen width with DLP. With LCD you probably would want to be 2.5 widths away. With CRT you can get much closer. There are generally 2 reasons for not getting too close with digital projectors. The first is screen door which is the effect of being able to see the gaps between pixels. The second is temporal dithering which is used by the video processor to cope with bandwidth restrictions when there is a lot of movement on screen. CRT isn't affected by either of these so is a good choice when you want low distance to screen ratio.

    So there you go

    CRT 6 1/2 foot wide
    DLP 5ft wide
    LCD 4ft wide

    The other problem you may have if your viewing possition is timmited to 10ft is the throw of your projector. Ironically some other the lenses work out nearly the same as some of the figures quoted above.
