Xibo with Samsung Syncmaster


We have many monitors Samsung SyncMaster 400MX-3. I have installed a Windows 7 Professionnal on their screen that have a little PC integrated. I have installed Xibo player on and they are functionnal. I want to turn on screen automatically at 08:00 AM without Wake On Lan. It’s not possible to defined this in the PC’s bios. There has people who have this configuration and has the same problem ?
