My three monitors have varying resolutions if that matters.

  • You will need to give us a little more information. What motherboard, and graphics cards do you have?

To have multiple monitors working with Flight Simulator X, you need a Video Card that allows you to hook up those monitors. If that is the case, configure them correctly via the control panel of Windows.

After that is all working, proceed with these Steps:

  • Start Flight Simulator X.
  • Click Learning Center.
  • Click the Index tab, and then click the letter D to go to the Display section.
  • Under Display, click Using Multiple Monitors.

Next, open the folder "%AppData%\Microsoft\FSX-SE" by pasting this path into your local explorer. Then open the file fsx_se.cfg with any text editor of your choice. Look for WideViewAspect=false and change it to WideViewAspect=true.

After doing that, you should be able to set a resolution that works with your setup in the options of FSX. However, I am note quite sure if this works with monitors with different resolutions. I assume this will only work correctly if you have 3 feature identical monitors.

  • As mentioned you will need at least 1 graphics card that supports this.

  • Thanks, this was very helpful in getting things set up. I already had my three monitors set up, of course, so no issues on the hardware front. :) The information in the Learning Center helped significantly, though it was a little incomplete for a beginner like myself (it wasn't obvious to me how to pan a view, for example, but I found it through a little experimentation: holding space while moving the mouse). The varying resolutions didn't end up being an issue, but I'm using windowed mode right now, so I can't confirm whether any of this works in full-screen mode. Jun 21, 2015 at 2:09
  • @Josh1billion If it was helpful and solved your issue, you should mark it as answer, so the question is higher rated in searches.
