Sorry for delay in response. I swapped my two tablets so the Surface Pro tablet is now used in landscape mode to display the GTN650Xi and the Android tablet is now in portrait orientation displaying the GTN750Xi, and, … lo and behold!!!… touch input works perfectly now on both tablets. So I suspect that my problem with the Surface Pro tablet was that the mapping of the 750 window to the display, when it was in portrait orientation, somehow disagreed with the mapping of the touch input, as touch was active, but the responses to touches were not appropriate for the displayed buttons being touched.
Anyway, I’m now a happy camper, and have a third (larger) Android touchscreen under the Christmas tree, for use with glass cockpit displays, and another monitor (fourth for my graphics card) on which I hope to display center consoles of airliners… underneath my main 3 displays.

I appreciate very much your careful responses to my former difficulties!!!

As I mentioned in another post, I have had the Surface tablet working perfectly as a touchscreen to drive the TDS GTN 750Xi, then when I rebooted (or something else I did), it stopped working correctly. That is, the touchpad is indeed active (with either Win7 or Win10 version), but the touches are received in the wrong spot. I.e., I touch one button, and with some probability, some other button acts as if I pressed that. It all works fine with the mouse, just not touch.
It strikes me that at some point, I was able to choose between absolute and relative coordinates for the touchscreen, and somehow, I can’t get that to come up in the settings anywhere, in either version. It is now set to absolute (as the status display in the driver shows me), and maybe that’s the problem, but I can’t figure out how to change that. Could you tell me where to go? I get to the client’s setup screen just fine, but there’s nothing there allowing me to choose between absolute and relative coordinates.
Any guidance much appreciated… perhaps absolute/relative is the problem… it has the right characteristics, namely, mapping the screen differently. Thanks!

Here is the second post.
What these pictures will show is
6) If I tell the main PC that screen 4 is in landscape mode, then the picture on the tablet rights itself, and, although squished, allows the mouse to function fine.
7) When the TDS GTN 750Xi is dragged into THIS view, it displays perfectly, and the mouse works perfectly (see the picture), AND the touchscreen is active (after “take control”), BUT the buttons are in different locations than displayed. That is:

I believe the touchscreen coordinate system is not being massaged so as to match the displayed screen orientation.

The disturbing thing is that I know it is possible to find a way to make it work properly, because I did have it working for a few days, until a reboot changed something (I don’t know what), and I haven’t gotten it working in the week since. Any help would thus be MUCH appreciated.

I think my problem is similar. I accidentally found a solution, and then on next restart, it was gone again, and I haven’t been able to get it working correctly … the former post was “touchscreen inop…” and Christian responded. Incidentally, all of this works fine on an Android tablet with the Android client.
Running the client from the MS Store, although I also tried the Win7 version at Spacedesk’s suggestion.
I’m trying to use the TDS GTN 750Xi FMS with MSFS 2020, and it won’t allow me to use the touchscreen on my Surface tablet … that is, I can make the touchscreen active (“take control”), but when I poke, the buttons triggered are not the buttons being displayed… i.e., the touchscreen’s view of what’s on the screen doesn’t agree with what’s displayed. Here’s what I’m learning:
1) I am testing WITHOUT STARTING MSFS at all, with the TDS GEN 750Xi in “Standalone” mode, to try to eliminate confounding factors.
2) The first pic below shows that the main (server) PC (in Win 11) has the “portrait flipped” selected as the tablet orientation (screen 4 to the PC).
3) On the tablet, in settings, the selected orientation is “portrait”, as shown in second pic.
4) Next pic shows that the “extended window” as seen on the tablet is SIDEWAYS, so some piece of software has rotated the view so the aspect ratio on the tablet is close to that on the main screens. But of course, that means it is turned 90 degrees.
5) The next pic shows what happens when the TDS GTN 750Xi is dragged onto the tablet… it is rotated just as the background screen was, so it sideways and not really usable. However, when the PC’s mouse is used, the buttons work fine, but after “take control” on the tablet, the buttons shown still do not respond to touches (at least not properly, although the touchscreen is clearly active, because dragging fingers around occasionally triggers responses from the 750Xi.

I have to do another post to show the remaining pictures, and I hope that will work, because this post will not let me upload more than 4 pictures. BUT what these pictures will show is

Here is the link to the Dropbox file where the zipped diagnostics are saved. Sorry for the
long delay!

Well, as so often happens in the real world, after I re-installed the MS Store Win 10 version of the viewer, started up the diagnostics in the server, and took control on the MS Surface tablet, the touchscreen started working… I’d done the same thing (minus the diagnostics step) several times before, to no good result, but right now, it’s finally working, at which I’m delighted! I would send along the zipped diagnostics files in case they would be of any use to you, but they came out to be 2.5MB, and the max size allowed below is 512KB.

Thanks for your helpful responses… I love your product!!!

Update:
Although I got an error message when trying to download the Windows 7 viewer, I have since learned that it actually DID download. I have installed it on the SURFACE tablet, and connected to the server, and it produces a reduced-size window, but works fine with the system mouse (i.e., the mouse from the main PC, to which the tablet looks like display 5). I have started the TDS GTNXi 750 in “Standalone” mode, which pops up on one of my main screens, then dragged it onto the tablet. There, using the system mouse, it works fine. Without using the “Take Control” trick, the finger touches do not work, and I clicked on the Spacedesk viewer window with the system mouse and activated “remote control.” The touchscreen still did not work to push any of the buttons on the 750. I used the tablet’s mouse to see how things were set up in Spacedesk, and saw the following: under Functionality, Display, Mouse remote, and Touchscreen (absolute) were checked. Under Settings, it showed the 5 lines (Resolution, Compression quality, etc.), but I saw nothing strange there, and I couldn’t click on anything and get any response with the tablet mouse. Here’s a picture of the screen under the Win 7 version (on my Win 10 tablet), in case that’s helpful…
Hope this provides some additional insight…

Yes, with the Win 10 (MS Store) viewer running, I can finger touch icons along the bottom and bring up a browser, settings, etc. So the screen is active outside the viewer.
I tried to download the Win 7 version, using both Chrome and Edge, but in both cases, it gives me the following:
HTML5 app prerequisites
Please delete all cached files, images and cookies on web browser settings to load the latest HTML5 viewer page
Requires latest version of web browser and operating system. Please update
Mozilla Firefox currently unsupported due to performance limitations

My tablet was purchased recently (used, but cleaned), and came with newly installed Windows 10 Home, version 22H2, and I installed the latest Chrome browser, so it’s not that my system is out of date. After the failure above, I went into Chrome and deleted all the history, killed Chrome and restarted it, went back to your website, and tried the Win 7 download again, but, unfortunately, with the same result. Any further ideas?
Thanks,
Erik

I just figured out how to switch between the Spacedesk window and the main window for the tablet, and when the Spacedesk window is not on the screen, then the buttons work fine… i.e., I can bring up the tablet’s “Settings” window by touching the settings icon, But the icons displayed on the bottom of the Spacedesk screen (such as the Settings icon for the server PC) do not work by touch, although they are fine by mouse click (clicking it brings the PC’s settings up on another monitor). So the connectivity is definitely there, just not the touch functionality.

[goodman@msu.edu]

If I disconnect Spacedesk viewer on the tablet, the touchscreen works normally. I can read mail, run apps, etc., at the touch of an icon. However, as soon as I connect the viewer, all of that touchscreen functionality disappears, whether or not I go through the “Take Control” procedure. I apologize that I’m not a tablet person nor, for fifteen years until recently, a Windows person. So I don’t know how to minimize the Spacedesk window, even using the mouse… I can click with the “system” mouse (i.e., the one plugged into the Server PC) when it’s on the tablet screen to push the buttons along the top and sides just off the Spacedesk-occupied portion of the screen, but none of them work for touch as long as the Spacedesk viewer is connected to the server. I hope this is responsive to your question, but I’m not at all sure, as I’m operating in pretty much of a vacuum with regard to tablet usage and more generally, any sophisticated usage of Windows (sorry!).

[goodman@msu.edu]

Incidentally, I also tried it in the other order… moving in the GTN 650 display onto the tablet before doing the “take control” move within that window. but thaT also didn’t seem to make any difference.

[goodman@msu.edu]

I’ve tried it both ways. First, I plugged a wired mouse into the SURFACE tablet, started the Spacedesk viewer on the tablet, and clicked inside the screen (before moving the TDS GTN 650 onto this screen). I got the menu popup, clicked on Take Control, then used my PC mouse to move the GTN display onto the tablet. Worked fine with the system mouse, but no touchscreen functionality.
Then I did it the other way… rebooted the tablet, started the viewer, used the one tap and 3-finger gesture to bring up the menu, again chose “Take Control”, but same result… GTN worked fine with system mouse, but touches didn’t work at all.

So I’m still puzzled… I was very excited and happy to get your reply above, but I must still be missing something in this process… any further ideas?
THanks very much!
Erik

A quick followup: I just found that the same process using an ancient Android tablet works just fine… whatever I drag onto the touchscreen responds just fine to finger pokes. So it seems likely to be either a MS Surface configuration problem or a problem with the Spacedesk viewer for Windows-based tablets. Hope that helps someone see what is likely the problem…
