Question

am planing to make a fixed frame projector screen by my self,and i want to know if i made a fixed frame projector screen by my self,whether it will be look as good as readymade fixed frame projector screens,heard tat there are two types of projector screen,they are : perforated and non-perforated screens .wat's the difference between these two screens ?..and which one will produce a high video clarity?and which is best to use?

Answer 1

Both can give a good picture. The choice comes down to whether you want to mount speakers (particularly the center speaker) behind the screen. If you do, you need an acoustically translucent screen.

Performated material is more prone to moire effects than non-perforated, although this is not likely an issue with properly designed cloth.

I made my own fixed screen and decided against the perforated screen material (see 1st link for one source -- and further info) largely because the size screen (110", 16:9) I wanted to build allowed me to mount speakers to the sides and below. I was able to use Blackout Cloth which is a bit less expensive, available locally, and does not attenuate sound.

In terms of how good it will look ... the screen itslef will (assuming you stretch it tight) look essentially identical to a commercial screen ... but the frame build quality will depend on you.

See a picture of results of my efforts at the 2nd link. You judge how well it stacks up against a commercial one ... works for me.

The 3rd link is to the AVS Forum DIY Screen Section -- lots of good info, and a place to get informed advice.
