Sorry this is a bit long winded and I wasn't sure whether to put it here or under hardware. I am a recent convert from MSFS to X-Plane 10. It's been working fine including Openscenery X and CRJ200 addon aircraft together with Saitek yoke, throttles and rudder pedals. I have 2 computers and 3 monitors and so wanting experiment expanding X-plane 10 to a full 3 screen wrap around I have bought another copy, installed it on the second computer and have it running on a second monitor. I have set up static IP addresses, set the master computer and set the IP of the master machine on the second machine. I have set lateral field of view to 45 degrees on each and set the lateral offset on the second computer to -45 degrees (it is on the left). I have checked all of the rendering options, location, date and time are set up the same on both computers. When starting X-plane 10 in this configuration I sometimes get an error message on the second computer saying it smacks of a corrupted file, I am not sure whether I should open X-plane. 10 on the main computer first and then the second computer or the other way round, maybe it doesn't matter Even when that doesn't happen the trouble is firstly it doesn't look right (this might be due to offsets and bezel alignments so I am not too worried about this), but more importantly when I start the take off roll the main computer and screen works fine but the second computer and screen stays static. The main computer (or joystick controls) don't seem to be talking to the second computer. I am obviously keen to get this resolved before building a third computer for the right hand screen. Also will the CRJ200 (or any other aircraft or scenery) installed on the main computer work across the 3 computers and screens. Thanks in advance for any help.
