now i want a front projector

[squirrel101]

after seeing the pics of you guys standing in front of your projected image i'm convinced that is the way to go.my movie room is 12' wide and 14' long so i may be able to achieve an image of about 101" but i suddenly became confused on screen size (fixed mount DIY) dimensions and cinescope (is that the curved screen?) and it looks like the new Panny is the best and most fogiving but i dunno would like to brand match with the pioneer elite but prob. can't afford it .

According to my math, if you use the 12' wall, at 144" (your widest scope screen) the height of the screen will be 60", which will yield a 122" screen (diagonal) for 16:9 programming. OF course, that's pushing it 'cuz you need to mask it and what not. So allowing 6" on each side of the 12' wall, your widest scope screen at 132" will have a height of 55", which will yield a 112" diagonal 16:9 screen.

If you put the screen up on the long wall, giving a 12" allowance for a balanced mounting and masking, a 156" scope screen (13' x 12) will have a 65" height and yield a 132" diagonal 16:9 screen.

That's all well and done but you have to figure out which side can the projector accomodate with the throw distance as well as the room logistics (entrance, wall outlets). As always the bigger the screen, the bigger the impact. Whether or not you can handle a big screen at the seating distance, well that's another matter.

Without the anamorphic lens, you don't need the curved screen (if you buy the AE3000).

I too, after viewing some pics of front projectors will be taking the plunge with the Panasonic. My only decision is 2.37:1 CIH or 16:9. Isn't it true if I go with a 16:9 screen I will get true 1920 x 1080, and CIH I will only see 1920 x 810? Is this a deciding factor for most people?

math...

the throw distance will be the 14' distance minus the depth of the projector , i used the calculator on that other website and the screen would only be about 101". so i need to build the screen according to the 16:9 in order to achieve the most picture detail?

Not sure of that model projector (didn't look it up) but lense to screen is the throw distance (as you know obviously) but make sure you compensate for wires sticking out of the back (most projectors have inputs on the back) as well as where the thing vents out the heat..... mine vents in the front and sides, but some vent through the back which requires more space also.........


The picture detail should be a little better on a CIH, but you can read more here.... http://www.avsforum.com/avs-vb/showthread.php?t=554901

Now, if you want to do self masking etc..... that's a pretty adventurous DIY screen...... 16:9 and CIH both have their own merits..... since the majority of DVDs were created for 16:9, and I own a lot of DVDs, that's what I went with.....

beta man which projector did you use and how much distance did you need to achieve that screen shot of Star Wars cause that looks really nice.

Hmmm. Using the calculator on Projector Central:

Using the 14' wall as the screen->
366cm (12 Feet) - 40cm (30cm Projector Depth + 10cm allowance) = 326cm of throw distance. You'll get an 82" 16:9 screen with 40" height and 72" width. If it's meant for CIH, the width is still 72" but height is 30", which means for 16:9, it's 61" diagonal.

Using the 12' wall as the screen->
427cm (14 Feet) - 40cm (30cm Projector Depth + 10cm allowance) = 387cm of throw distance. You'll get a 98" 16:9 screen with 48" height and 85" width. If it's meant for CIH, the width is still 85" but height is 35", which means for 16:9, it's 72.3" diagonal.

Smaller than my previous calculations.

Wait, if you are talking a CIH system, then the width changes while the height is static:

For the first, your height would remain 40" with widths of 71.1" for 16:9 and 94" for 2.35:1.

For the second, your height would remain 48" with widths of 85.33" for 16:9 and 112.8" for 2.35:1.

You just have to make sure that there is enough lens zoom to achieve the picture widths (1.78:1 and 2.35:1) for the screen height that you choose at your fixed throw distance, assuming you want to do the zoom method of CIH.
