Generally speaking, this is a nightmare to deal with. The solution, starting in Processing 4.0 beta 6 has two parts:
* When running from the PDE, pass the `--ui-scale` parameter to `PApplet` (see the code for `processing.mode.java.Runner`) based on what comes back from `Toolkit.getScreenResolution()`.
* When running independently, check for that parameter, and if it's not set, launch a tiny helper app that just returns the DPI value.
* When running independently, check for that parameter, and if it's not set, launch a tiny helper app that just returns the DPI value.
With those values in hand, the sketch sets the `sun.java2d.uiScale` to either 1 or 2. Using fractional values produces [ugly results](https://github.com/processing/processing4/issues/378). Similarly, we do not set uiScale to 3 when scaling is at 300%. If you want larger sketches, use `scale()` in your code.

Did not use this approach because it would require Windows testing anyway, so it has limited utility.

## Use JNA
This is a fairly clean approach with a couple major downsides. One is adding 3 MB of JARs to each application. That is larger than all of `processing.core`, but you could make an argument that core is already large because of JOGL.

## Use a Registry Key
This would be a simple method to make a single command line call to `reg query` or similar, but was unable to find a suitable property that was reliable enough.
