really thanks for the reply guys!
i read documentations and the features of all software you suggested me.
seems like the only valid solution for my purposes are “multiscreener” and “dataton watchout”.
unfortunately multiscreener works very bad with 1080 videos..watchout instead is PERFECT under all aspects, but the usb dongles for the license are really really really too expensive for a videowall with 9 slaves.
also “syncmakerpro” looks a valid software, but it doesn’t permit the impression of a logo…i really need to place a line of pixel on the top of the monitor, over all the other contents: is a line wich control the hardware of the monitor (they’re 3d stereoscopic monitors).
maybe is off topic, but if you know how can i place this line on the bottom of a fullscreen video, syncmakerpro could be the right solution!
thanks again!
