Consistent GUI screen sizing on laptop and monitor

Hi, so I have a GUI that I mainly work on at the internship I have, where I use a 1920x1080 resolution monitor. I verified that Matlab was using this same resolution by doing the get(0,'screensize') command. However, I went to work on it at home on my laptop, which is also 1920x1080 resolution, and the layout for the GUI is all messed up. Furthemore, when I did get(0,'screensize'), it says the resolution is 1280x720 even though I'm positive my laptop's screen is 1920x1080 resolution. How do I fix this so that my GUI works on both my laptop and the monitor I work on? Is there some command I can do on my laptop where I can change the Matlab resolution to 1920x1080? Does it have something to do with the fact that my laptops screen is physically smaller than the monitor screen (13'' vs roughly 24'')?

Please confirm that you are not connecting your laptop to an external monitor - in this case monitor 0 might refer to the external monitor and not your laptop (depending on your selected displays layout).
will show you the layout and size of all active monitors that Matlab recognizes.

@Rik Display scaling was exactly the issue, mine was set to 150% and when I changed it back to 100%, it worked. Thanks for the helpful response! One more thing though, so when I disable display scaling unfortunately it causes my screen to look pretty zoomed out- having the display scaling is ideal. With this in mind, is there any easy way to scale my gui to work when the display is scaled?

I don't know how you could solve this, but I suggest you contact Mathworks support to see if they consider this a bug.

You can set all the 'units' properties of all the controls to 'normalized'. You can also set the Position property to [0 0 1 1], if you want full screen.

@Mason Dyess, the best solution is to just specify 'Units', 'Normalize' for each GUI object within your code. However, here's a way to do that programmatically by running these two lines just after your GUI is created. The first line searches for any object in your GUI that has the "units" property. The second line then changes the units for all of those objects.
objHandles = findall(GUI_figure_handle, '-property', 'Units');
set(objHandles, 'Units', 'Normalize')

@Adam, actually, that misses a point. That presuposes that all sizes are correct, which is apparently not the case. So Mason would need to run this code on a computer where the sizes turn out correct, and then use the result to adapt the code to generate the GUI with normalized units.
(although to be fair, it isn't entirely clear to me why the layout would break, instead of everything just being scaled down and all proportions staying correct)

Thanks guys, switching to normalized units was pretty helpful for auto-resizing. However, the major issue that was causing me problems was display scaling, so thanks to @Rik for suggesting that as the potential cause.

I am assuming that you are using GUIDE to build your GUI.

Hi, I actually didn't use GUIDE at all to build my GUI. I instead programmatically built it using commands like uicontrol.
