With the BalancedMultwindow you have to set the following field values accurate. hServers,vServers Number of vertical and horizontal display servers size the summed resolution of all display servers The MultidisplayWindow can guess some values for this fields, but as the Balanced window muts be able to transfers pixel areas to the right destination, this values must match exaclty The number of servers can be larger then hServers x vServers. The remaining servers are used as pure rendering servers. e.g. if you have 2 projectors wiht a 1280 x 1024 resolution you have to set hServers=2, vServers=1, size 2560,1024. If you want to use 4 servers to render to this two projectors you an set servers = [projHost1,projHost2, otherHost1,otherHost2] Hope this helps Marcus > Are you doing stereo projection with BalancedMW?
