I have a high-DPI laptop screen and a normal DPI external monitor connected to it - and I work on both of them. Last time I tested (granted that was a while back), the fpGUI application detects the DPI of the monitor it is launched on. I can't remember what happens when you drag that application from one monitor to another (where they have varying dpi values). [Nothing related to fpGUI] I do know that Windows 10 is seriously broken in this regard. At least I think it is broken, or the implementation is seriously sh*t. eg: Take an application like Delphi XE3 and launch it on a 140+ dpi monitor. Open a debug window (or any non-docked IDE window). Drag that window to the 96dpi monitor. Boom, you have the over-scaled fuzzy looking window. Even dragging a single window application so that just over 50% of the window appears on the 96dpi monitor, and the same thing happens. Less than 50% overlap, and all is well. WTF Microsoft!!! I've got this issue at work every day. To alleviate the problem slightly, I have to change the "default monitor" to the lower dpi monitor.

Hello, Yes that's the needed value, is the binding which is missing, not detected as I'm not using scaled applications. It will be added in the next LCL-fpGUI update. -- -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org https://lists.lazarus-ide.org/listinfo/lazarus
