Hello,
I'm using projectors in my work.
I uses four projectors to present on four screens.
Is there a way to connect my laptop to the four projectors?
Is there a way to display the laptop on all screens at same time?
Please Reply as soon as possible.
Thanks.

Use a video distribution amplifier/splitter (examples: Distribution Amps (http://www.svideo.com/vg.html)). The splitter will need to support the resolution and refresh rate of the laptop's display output and be compatible with the laptop's connection as well as the projectors' connection. Additional cabling adapters may be needed if the projectors do not have standard VGA input connections.
