Latte, Mike or any projecton gurus

As some of you know I have three 46" diagonal 4:3 panels that I've been projection onto with three 16:9 projectors. This gives me a 108" wide screen with a diagonal of 135". But since the projectors are 16" this leaves me quite a bit of real estate on top and the bottom of the screen. I have warping software which lines up the seams perfectly vertically so I don't see any seems. But I want to take advantage of the extra real estate provided by the 4:3 screens horizontally.

I have two of the BenQ 1080ST 1080p short throw projectors in my Amazon cart. I was planning on getting two of these projectors and lining them up so that they each cover 1/2 of the 108" across and would fill the entire 4:3 screen horizontally. Then use the blending software for the seam in the middle.

I hope this makes sense. So basically I would save on a third projector by actually running two widescreens to cover the three 4:3 panels.

Any help is appreciated.

thanks

2 16:9 projectors gives you 32:9 ratio

3 4:3 panels gives you 12:3 = 36:9 ratio

Your projectors will now throw taller than your screens or won't reach the sides.

Also I believe the short throw projectors tend to suffer conformity issues so may want to look into that before trying to hit perfect alignment...

The model I have is the BenQ W1070, just got the one.
Sold the Optoma GT 750 models I had...

Like everything the best thing to do is experiment however with Nvidia I believe it only supports 3 screens or more, you need to check that but just an assumption I had. Some of you have much more experience in multi-screen configs. My own tests have only been basic with multi projectors.

The spec/price factors for the Benq W1070 make it a strong contender also offering 4:3 WUXGA, something very few support.

I'd say every screen option from 3x 16:9 - 5x portrait all have drawbacks and limitations. With 5, not supporting 3D is one, cost another, insane gfx card performance to power those pixels and heat a further.

Also "3D Vision Surround" is only possible upto 720p (ACER inf) as I know of no 1080p 3D projector that is supported. Then their is the factors of using triple 4:3 Vs 16:9 or mixes of 16:9 with dual 4:3 or even possible future 21:9 with dual 4:3 at the sides is all interesting.

Personal preference is much of it too for each user.
Thoughts I have, would be to get a screen size for the screen distance your doing that gives a realistic feel. The problem for many is available space within the room used. This is why short throw type models can be very advantageous.

I cannot comment on issues with alignment with short throw models (wasn't a case with GT5 with GT750) however their are people out their on forums with multiple GT720 or GT750 using PC that I have not read having such issues.

Factors:
Screen Size
Screen Distance
Game FOV

It no doubt requires a great deal of testing but I think every option, be it curved, angled or flat projection all have their own good and bad factors too.

"Remco" style giving cockpit realism on 1-3 screens with rear/front projection would be possible with a model like the W1070. Maybe more models this year will offer similar specs or better but it is IMO one of the best models worth considering in its price point.
