Hi all, I rarely use Windows, but noticed that Rgui itself and plots under Windows using the windows() plotting device looked very fuzzy even with a 4k resolution. This seems to be related to DPI scaling, since the system was using 200% scaling (so that things aren't super tiny). If I change the high DPI settings for Rgui (Properties, Compatibility, Change high DPI settings, High DPI scaling override, Application), then things are nice and crisp. Is this common knowledge for Windows people? If not, should this be documented somewhere, like the Windows FAQ?

Resolution of RGui With High DPI Scaling

Thanks a lot for the solution. I always use the Windows system, but I wasn't aware of this setting before. Best, Jinsong
