Dual unit installation wont maintain screen positions - Gary Spender - 09-24-2026
Has anyone had any issues , or can anyone offer a solution to an issue I am having with a dual GTN750 installlation.
The units work as expected , and are displayed on RealsimGear GTN750 bezels, all hardware / buttons / touch screen work as expected.
Unit 1 will not stay where I put it on screen, I can use the monitor settings at bottom of settings in the plugin, I can move it manually, I can maximise it, I can shrink it so it definitely is contained within the boundaries of the GTN 750 hardware screen. On restarting x-plane the display always starts on left hand side of montior 0 about 1/4 of the way up from the bottom.
The saved rectangle co-ordinates appear sensible, although the height is alwaysa saved as 777 pixels and not 800.
I have manually edited the .ini file to try and move it , no joy with that. I have also made the file read only to prevent changes being saved erroneoulsy by x-plane.
X-Plane version 11.55 and latest TDS version.
.ini file attached to this post, with a .txt extension as the website didn't seem to like .ini
Grateful for any suggestions.

Hello,
As a first request, please do not make any TDSGTN.ini files read-only, this will disrupt our system.
Is this issue in regards to X-Plane 11 only? Have you tested/are you running in X-Plane 12 as well?
We have been working on a similar bug for X-Plane 12 and the fix will be included in the next TDS GTNXI XPlane release V1.0.1.6
However we are interested in the details for X-Plane 11 so we can see if this is the same bug or a different one.
Do you use the TDS GTNXi XPlane Plugins/Settings menu to set the GTNXi window to full screen? This is through our menu item and not within X-Plane or manually?
Thank you.

Hi,
Thanks for the reply.
The read only file was a clutch at straws on my part, after an afternoon of trying to make it work, it has not been left readonly.
Yes I have tried the "full screen" option, seems to work on unit 2 , not on unit 1. I can move unit 1 to the second screen using full screen but just not the first screen.
They "touch" in display settings, with both unit 1 and unit 2 screens being stacked at the bottom of the primary scenery display , so beneath it in display settings.

Hello,
Thank you for the information, can you please answer our questions, as posted in our first response?
RE: Dual unit installation wont maintain screen positions - Gary Spender - 09-24-2026
Yes tried full screen in your menus. Unit 1 will not save the position , it can be manually moved. I am not near the PC at the moment for a few days, but I believe any attempt to make at least unit 1 full screen resulted in it being displayed on unit 2 or the full screen "request" being ignored.
I have tried x-plane 12 with a 650 realsim gear unit and 750 home made unit and the full screen options appear to work flawlessly on that installation. The XP12 installation is on a different PC. I can't currently install XP12 on the one that exhibits the issue.

Thank you for the information. In this case we ask that you please test this again after we release version 1.0.1.6 of the TDS GTNXi XPlane and if the problem continues exhibiting, to let us know so we can troubleshoot it a different way.
