I have three monitors, with center monitor selected as the Main Monitor. I can use all three in X-plane if I select Windowed Simulator and drag the image across the three monitors. Unfortunately the instrument panel is off set to the left display and the image is distorted. I also lose a bit of the scene with the tool bars at the top and bottom of the display.
I have tried setting the Main Monitor in the Graphics Settings to Full Screen Simulator, with the resolution at the Default Monitor Settings. In Visuals Settings I have Forward with 3-D cockpit selected. Field of View is set to Lateral field of view at 45.0 degrees, Vertical field of view 33.8 degrees (defaults to this value), and Visual Offsets to 0.00 degrees.
When I try to set Monitor 1 or Monitor 2 to Full Screen Simulator, X-plane crashes and a crash log dialog box appears. I have forwarded that dialog box to X-Plane support.
I have read the manual and have watched several YouTube videos explaining the method to achieve a three monitor view. I have been a user of X-plane 8, 9, 10, and now 11. I have been running X-Plane10 with the screen resolution set to 5760x1080 with pretty good results. However those settings have not worked for me in X-Plane 11. Any help or ideas would be appreciated.
