High dpi problem for deployed gui

Hi all,

My GUI does not show correctly as a deployed application on high DPI displays. The GUI should be 1330 x 740. Strangely, the height (740) is shown perfectly, but the width is only 1162 in deployed mode on a high DPI. If I deploy my application to a pc without high DPI, the GUI shows perfectly.

The GUI still shows all elements, but they are all narrower. Strings are therefor not readable anymore.

Another striking thing: I use Yair's findjobj function to center some table content horizontally. However, also those cells are not centered, but instead these cells are off-center to the right. I think this indicates that the underlying java CAN detect the intended width of the table columns, but the GUI is just wrongly scaled. Here's a picture:

I disabled Windows 10 application scaling. I created the GUI with GUIDE. The figure is set in characters (but the problem persists if I set the figure to "normalized"). The figure is non-resizable. I use both MATLAB 2016a and 2017a (and I have the problem in both versions). The screen resolution is 1920x1080.

Does anybody know a fix or a workaround? Any help is appreciated!

Thanks, Vincent

A workaround would be to go into the application's properties\compatibility and select "Override high DPI scaling behavior" performed by System. Seems to do the trick.
