Beamer screen position
Hi all,

Before ordering a beamer I faced some limitations in my room, and so I am afraid, that I cannot find the best position for the screen.

But I have never tested it, so I dont know the best position to view 3D-vision games on a beamer screen.

The position doesnt matter for my normal 2D beamer. Is there a difference in 3D, so that I have to look directly into the middle of the screen or something like that?
What is the best position? A, B or C ?

Thanks!

You basically need to find something that is comfortable look at. For instance, I am in a small room and the projector is over my head. The image is projected above a couch, so I have to look up slightly. My eyes are about 1/3 of the way from the bottom of the screen. I find this to be quite comfortable.

Enjoy,

I asked this question because I heard that it is important to get the right viewing angle on LCDs, to get the full 3D performance.

And that is not the same on beamer setups? Thx!

From what I understand about projector screens, depending on the type of surface you are projecting onto, there are better angles than others. I seem to remember the glass bead projectors work best from above projecting down. (C). What screen were you planning on using?

I used this screen for my first selfmade projection wall.

The second one, will be selfmade too, but I think I need to choose a screen with more gain.
BTW: I am very happy with this screen.

You have to read a lot about how a high gain screen works. Generally, your sweetspot is pretty limited, and depending on the type of the screen you HAVE to mount the projector 1:high or 2:low.

(1:Angular reflective: silver , 2:retroreflective: glass beaded)

Then there are also very high quality rear projection screens that can easily look the best (type2). Thought of projecting into the room , thru the door, out of a hallway? I think that's a very good idea, you minimise noise and ambient light pollution in one go!!!...

Needless to say, I think white is worthless for 3d, lacks the contrast, lacks the punch.

Definetly "A"

I have to look up at my screen somewhat and I know I'd prefer the "a" setup

I higher gain (more reflective) screen has a more narrow viewing angle. A more matte screens has a wider viewing angle. FYI, my screen is Behr Silver Screen paint on foam board.
