Hi

Recently my DIAdem has started consequently showing pop-up messages almost off my screen in the lower right-hand corner. I run my PC with three different screens; two HD ones and a 4k. This happens if I have the DIAdem window on either one of my HD screens, but not on the 4k one.

My own guess is that the program somehow thinks that there's more space on the HD screens than there are in reality since there's a 4k screen present as well.

Any ideas on fixing this?

Thanks

Martin

Hi Martin,

There are 3 DPI Awareness Modes:

1. DPI Unaware
2. System DPI Awareness
3. Per-Monitor DPI Awareness

DIAdem supports no 2.

Explanation:

System DPI Awareness

Desktop applications that are system DPI aware typically detect the DPI of the primary connected monitor on startup. During initialization, they layout their UI appropriately (sizing controls, choosing font sizes, loading assets, etc.) for that single DPI. System DPI-aware applications are not DPI scaled by Windows (bitmap stretched) on the primary display (unless the display scale factor changes while the application is running). When the application is moved to a display with a different scale factor (or the display scale factor otherwise changes), Windows will bitmap stretch the application bitmap, which can result in it being blurry. Effectively, System-DPI-aware desktop applications only render correctly at a single display scale factor and become blurry whenever the DPI changes.

So if yur primary monitor is the 4K then it explains your behavior.

I hope this info can help.

Greetings

Walter
