    Broadcast a desktop to other PCs

    Hi there,

    I would like to know how people would approach this problem..

    We intend to set up a large room with a main display at the front and what ever is displayed on the large projected image is broadcast simultaniously on upto 6 other displays at the same time...

    Do you just split the signal and push it to the other displays?
    Do you attach a pc to each of the other displays and push the image around the network? (it would be handy to use these displays for smaller group work anyway) if so.. How?

    answers on a post card...

    What about a VGA splitter?

    Try this link:Maplin > 8-Way VGA Splitter

    We use Netsupport School for IT bases, which is pretty good and can do what you're after (and a fair bit more). It may be more than you want to pay though.

    This will do what you need. The users on the 6 screens can even display their desktop too if you allow them. Great for interactive type lessons

    I assume you mean the 6 other displays are going to be scattered around the school. If that's so, probably VGA-over-cat5 would suit you best. VGA signals can be sent over standard cat5 cable as used for your network (not: not actually over your network, that would be VGA-over-ethernet or VGA-over-IP, which is getting more complicated, this just uses the same cable). Google/search these forums for "baluns", that's the device you want.

    I did this the cheapo way - put a VNC server on the front machine, installed as an application rather than a service IIRC.

    On workstations at the back of the room I installed a listening VNC client, launching at startup.

    The front machine has a couple of batch files, one to start the VNC server and add each of the clients, one to kill the VNC server.
