Customize the size of RoboDK text and interface

Hi I have a strange problem. I haven't intentionally changed any setting but the text size of my options windows that you can open with F3 on any object or item is suddenly huge to the point where the software is almost unusable as it takes up almost the entire workspace.

I can change the size of text in the tree and the icons toolbar from the Tools-Options menu but these seem to be unrelated parameters.

I'm sure it's a simple fix but need some help.

Thanks

I'm assuming that the moderators / support in the forum don't have a solution?

This issue can happen with high DPI screens. More specifically, if you have 2 screens with different DPI (different pixel density).

I recommend you to start RoboDK by double clicking this file and you'll see the text and icons bigger (this will make RoboDK show 2 times bigger by default):
C:/RoboDK/RoboDK-Start-ScaleHighDPI.bat
This should give you consistent scaling in RoboDK. You can edit this BAT file and change the scale factor to 1 instead of 2.
Example:
set QT_SCALE_FACTOR=1

If you want to reduce or adjust the size of icons you can set the size in the Tools-Options menu (General tab).

I've just emailed you as well but I can confirm that the scale factor isn't helping as it rescales all text as opposed to just the text in the F3 options and toolbar.

The text in the tree and the standard Windows window text (File, Edit etc.) are not affected.

One of my students had this issue once because his "main screen" (for Windows) was his laptop 4k screen and he was running RoboDK on his second screen at 1080p.

We fixed the issue by simply having the 1080p screen as the "main screen" according to Windows.

I don't actually run a 2nd screen on this laptop. Do you think I need to reinstall?

Try this first:

Close RoboDK

Go to C:\Users\XXX\AppData\Roaming\RoboDK
Delete the content of the folder.

Restart RoboDK

Great thanks! That did the trick. It seems strange that my layout settings changed but just glad to be back to normal.

Appreciate the help

I'm wondering if it has anything to do with me running games on the laptop at a different screen resolution while robodk is minimised in the background...

Otherwise I really have no idea to help you guys understand what might have happened

We'll keep that information in mind.
Thanks for the feedback.
