Assuming your screen a motorised type and is able to move down and up when you press the remote, it means that the motor is working well. 2 possible reason are:-
1), The limiter mechanism to stop the movement for the up and down position is faulty or misalign. Up limiter in this case require check and realignment.
2), The end of the screen ( the bottom ) while closing ( move up ) stopped too late, over shot and it fell down on the other side causing that extra length hanging. Up limiter in this case require check and realignment.
Pls contact your local Dalite support if you are unable to find a repair man.
Hello, Most projectors have a 1/8 inch (mono) or tip and sleeve female connector for screen trigger and output 12volts dc when the projector is powered up. So if the Optima screen has the optional trig in and it's 12 volts the cable is very easy to put together. Optima may have a cable available or you could spend just a few bucks at Radio Shack and your all set.
There is a rubber grommet on the left top of the projection screen, insert the supplied Allen key and turn anticlockwise and adjust turn by turn till the screen rolls out with just 2 to 3" of the black border shows on the top
Have you tested the source machine on another TV or projector. The picture might be rolling before it gets to the projector so you need to verify whether it is the source machine or the content then you might be able to determine if it is the actual projector. Sounds like the vertical sync has got lost somewhere.
Hope that helps.
