Did some research on the Blackout Cloth.... WOW!!! seems to be the fabric to use for a projector screen and it's cheap.

It's not black, it's a grayish color, like battleship gray or a bit lighter. Google it and you'll be surprised at the information.

So you're using 3 projectors? That's awesome! Do you have pictures of this posted anywhere?

What kind of projectors are you using? whats your resolution? Are you using triple head to go? looks fantastic.

Short-throw lenses for projectors tend to be pretty expensive, so I think a lot of guys use folded optics to shorten the throw distance. They set up a first-surface mirror to bounce the image onto a screen. This can cut your throw distance in about half.

I've experimented with folded optics too. Make sure you buy a first-surface, also called front-surface mirror. Also, make your projector mount, mirror mount and screen adjustable, so you can move them around to fine-tune the image.

You know i tried messing with a flexible plexiglass and could not get the angle-distance-height thing to work quite right and gave up for now. Could you post or point me to a good place to see it. I tried with the projector in front, up high, down low.. I tried with the mirrored surface up high, and down low but never could get it. And the curve i was using was too curved. The size plexi i used was approximately 30"X36" on a screen 50" highby 60" wide in a 45 degree configuration. Just way too mych distortion and keystoning goin on..

Hi Matt,

The projectors are InFocus IN2104's (http://www.infocus.com/Products/Projectors/IN2104.aspx).

Their resolution is 1024 x 768 and they are indeed driven of a TH2GO box
connected to a HP Pavilion a6631nl Desktop PC (2.6 GHz Interl Core 2 Duo E7200 with 3 GB memory) equipped with an ATI Radeon HD 3650 Graphics card.

The projectors were on sale (in NL) which was part of the selection criteria.
Might have been better to go for short throw projectors but these come at more or less double the price of my IN2104's.
Same story for the PC. For the moment it works fine (still making changes to
various .cfg files though in an attempt to find the best pic quality vs performance ratio).

In the future I am planning to modify the config to look like NicD''s setup (5 windows spread over 3 projectors). Current PC does not have enough power to do this (framerate drops dramatically). So, when budget permits I'll go for a new I7 machine and make the Pavilion the flight dynamics machine (which task is now performed by the Laptop shown on one of the pics).

Hope this helps but just let me know if you need more detail.

Cheers,

Martin

........(still making changes to

One of the "nice" things (you could also as easily say "awful") when using 1024 x 768 projectors for the exterior views, is that you CAN easily reduce a lot of "visual quality" settings and not really be able to SEE the change in the view. The view is already rather compormised when compared to using a lcd screen at some incredible level of resolution.

So you can gain fps without sacrificing a lot of the quality you'd actuall see.

The real goal would be a projector that is as high a rez as the best monitors. Now THAT would be something to see.

best,

I know it's a little bit expensive! but this screen can offer you up to 200 degrees of view, and you can get it in this link:

Hi Martin,

How did yu get the Matrox to work with the projector?
I'm trying to get my 2 LCD TV's to work with the TH2GO, but no image at all.
Normal computer monitors work fine and TV directly connected to the videocard also works.

Rgds,
Benno

Benno, are all the three units set to the same resolution?

Matt Olieman

[Flying_Dutchman]

Yes, TV automatically selects whatever's needed
There are now only two screens left (2x37" is big enough)
Strange thing is that, when you attach the normal 19" screens back on the TH2GO a normal image appears.
With the TV's there is not even a signal

Rgds,
Benno
