Frequently asked questions
|Can I project onto a white wall?|
A white wall is often used as an alternative for a projection screen. Both appear white at first glance, so what is the difference?
||A projection screen fabric has a special coating that possesses unique reflective characteristics. A white wall does not have these features. |
||The Projecta projection screens all have black borders. The black borders increase the perceived clarity of the reflected image. |
||A projection screen fabric hangs flat and taut. This creates an optimal surface for displaying the image. |
If you purchase a projector for your professional presentation or home cinema, then buying a projection screen may certainly be considered just as wise. You are looking for the optimum image, and you will only get this with a projection screen.
How do you operate the spring-operated screen?
Unrolling the screen: Pull the screen down using the cord/handle and stop it once it reaches the desired position. The locking mechanism will ensure that the screen remains in that position.
Rolling the screen: Pull the screen down slightly at a reasonable speed (the screen will be unlocked) and allow it to then roll back in, without stopping it, at a reasonably rapid pace. If the screen rolls up too slowly, it will stop in the locked position.
Does my electrical screen come equipped with a remote control?
Every electrical projection screen comes equipped with a 3-metre long connection cable and a remote control.
Which mounting materials for installation on the wall or the ceiling are standard included?
Every projection screen comes equipped with mounting brackets for mounting directly on the wall and on the ceiling. The corresponding screws and plugs are also included standard with the screen. The following accessories are possible:
Extra ceiling brackets
Should you wish to place the screen in a high room or under a recessed ceiling in order to bridge the "empty" space, you may order special ceiling brackets as accessories for this purpose. These brackets have a maximum length of 100 cm and may be shortened to any desired length at the user's discretion.
Extra wall brackets
In certain cases, it may be desirable to mount the projection screen at a certain distance from the wall. This may be the case, for example, if a painting is hanging where the projection screen will need to be mounted, or, in the case of overhead projection, if the projection screen fabric must be placed at an angle to prevent a distortion of the image. The OHP extension arms have a maximum length of 75 cm.
May the projection screen fabric be cleaned?
You may remove a small stain from the fabric with BrightSight or water and soft soap. Under no circumstances may caustic substances be used for stain removal.
Important! When you roll the screen, make sure that no insects have remained on the screen fabric. This will result in ineffaceable stains.
I have noticed that for a brief period after receiving my projection screen, the screen fabric emits an odour; what is this odour and will it disappear?
There are softening agents incorporated into the screen fabric in order to ensure that the fabric remains as flexible as possible. These softening agents emit a strong scent. If you allow the projection screen to hang open for several days, the scent will disappear on its own.
Can I also hang the screen fabric in front of the window since the back is black in colour?
Projection screen fabric is not a blackout screen. In spite of the black backing on the fabric, it is not 100% lightproof. You may hang a projection screen in front of a window without worrying that it will be damaged or wear out faster. However, in order to be able to enjoy it to its fullest, we recommend that you hang the screen fabric elsewhere, certainly under bright conditions.
Is it possible to operate both the projection screen and the projector with one remote control?
If your projector is equipped with a special output (known as a “screen trigger”), it is possible to connect it to a control module. The control module may serve as a control device for the projector as well as for the projection screen. For further information, please consult your AV specialist.
