I have a IMac 27 inch. It has too lightning ports, I have too external monitors plugged into them HDMI. I would like to run centre monitor as the front windshield with the two external monitors showing the sides. Is this possible? I've also tried to get center [Computer} monitor running the plane View with an external monitor running the map. But I can't get the map off the center monitor. I've unchecked run full screen at this resolution, and even with the other monitors unplugged and just using the Mac computer I can't even grab the bottom right corner with the mouse to scale the size of the screen. I should also mention that earlier I clicked on the on the green window icon to make xplane fullscreen. And now when I move my mouse to the top of the screen no longer gives me the option to minimize or take the screen out of the fullscreen.

At this time I am running just the trial version. Wanted to get this working before purchasing it.

I realize that this is a confusing question but, even after Reading all I can find, I am totally lost has to how to make this work.

Any suggestions or input would be greatly appreciated.

Thanks, Aaron.

I'm having the exact same problem with almost the exact same equipment.  Let me know if you find a solution.  In the mean time, I'll stick with FSX I quess....

Aaron I am also having the exact problem. Been at this for 4 hours trying to make this work on my new iMac 27 inch 2015 model just purchased this iMac three days ago. I hope Xplane technical support has figured out a way to make the cock pit view among three monitors on an i Mac 27 inch in the middle with two monitors via 2 thunderbolt ports to HDMI. I got 1 monitor on the left & another on the right with the iMac in the middle. Read the manuel, I have done tried it all Aaron. Have you figured out a solution? or X Plane technical support sent you an answer?

So you have read the section of the X-Plane manual about multi-monitor set ups?  It has multiple suggestions.

To use the map on one monitor, you must have "display IOS & cockpit on two monitors" checked in the rendering options. If you check the full screen box in the rendering settings, the IOS screen (the map) will only display on the main computer monitor -- on the iMac in this case--and the extra view will display on the right.  Only if you keep it windowed and can you stretch the corners and move it where you would like.

If you have used the green +  button to make the window full screen, you should be able to grab any of the window's corners or edges and drag them in to shrink it again.

Thanks jroberts
Yes I did read the manual.
I also spoke xplane people today. I was told with my computer set up I should be able to run the Mac computer Monitor as  the front the plane and then use the two side monitors as the side windows. That would be my endgame.

I have tried clicking on the corners and I can see where it should let me grab. However it will not let me grab the corner to resize the window. Even when the other two monitors are unplugged and I'm just using iMac.
I'm wondering if I should delete this and reinstall the program. Because now every time I open it up I can't access the red X close, yellow minimize, or green plus button. It starts right in full-screen Mode.

I don't know if this would help at all, but I'll list the specs of what I'm working with.
The computer was bought new one year ago.
OSX EL Capitan
iMac (27-inch, Late 2013)
Processor: 3.5 GHz intel core i7
Storage: Fusion Drive 1.12 TB
Memory: 24 GB 1600 MHz DDR3
Graphics: NVIDIA GeForce GTX 780M 4096 MB
This has too separate Thunderbolt Ports each connected to HDMI cable going to the
Two external identical monitors.

Which are: Samsung SyncMaster PX2370 LED

Are there any other sites you suggest I could read to help with this?

Thanks again for your help

I am trying to do the exact same thing to no avail.  I was able to stretch my screen across 3 monitors but I had 2 problems: Graphics were distorted and there was a huge lag in response from my Yoke and pedals. I hope someone know how to help with this! BTW in order to get my screen to stretch I had to go to Pref, then mission control and uncheck "displays have separate" spaces box.

Aaron, I'm sorry I didn't see your comment earlier. If you haven't already tried a new install, you can recreate a new install it by simply moving the preferences folder out to the desktop. (It's found in the Output folder.)

Honestly, based on the information in our manual it sounds like if you only have one computer, multiple monitors will only display one very large screen, or two screens (the IOS and cockpit). I don't see an explanation for setting up extra monitors as side windows unless you have more than one computer running X-Plane.

Hi Aaron,

If you were running Windows you could quite easily link 3 screens together as one to create side windows.

The way I see you having an out is via your graphics card.

I run a Nvidia Geforce GTX 780ti card with my machine.  The nvidia software also has the ability to emulate windows giving you the ability to link 3 screens as one.  The problem will be however, to gain maximum benefit all screens should be of the same make, model, size and same refresh rate.

I haven't tried the linking as yet but seen it done.  Google details of your card on how to do it through Nvidia.

Hope this helps to some degree.
