Ultra Short Throw

[petcsy]

Hello,

 

Can you project the image of an ultra short throw onto a pull down screen without distortion? The unit projects at an 80 degree angle. Any success in doing so on a pull down screen.

Yes we do this when a mobile set up is required. You can keystone the image to square it up and away you go

I was advised that you need a tensioned screen to avoid "ripple" effects. Fairly widely available, but more expensive than simple drop down screens.

We have done it for ~90" diaganol pull down screens. They do get a bit of curve at the edge of the screen but other than that it works quite well. Fixed or tensioned screen is ideal though - but quite a lot extra $$$$

We have an ultra short throw projecting onto a normal pulldown-type screen. Haven't had any significant problems.

I've used it in the hall in one school, and it worked relatively well, just be a bit careful around the edges if it's not a particularly good drop down screen. If you are using it just one area though, I've used projection paint before now onto some hard board screwed to the wall which worked really well!
