Hello @Grusat,

I also got this working (x1 scaling) on my W10 PC by passing these to command line in IntelliJ:

This required the following:

There is a reference to this in the GitHub resources I shared but I had to do some work on how to inject these into IntelliJ settings to add to command line.

I found the solution to my problem :  
Just add

`System.setProperty("sun.java2d.uiScale", "1");`  
before the `PApplet.runSketch()`

It desactivates the auto scaling with Windows parameters.

Thank you all for your help !

I was experimenting with JavaFX (FX2D Renderer) and had a similar issue.

This works for FX2D renderer:

Cool beans!

I was able to use this with sketches as well:

> Hello folks! Forcing 1:1 Pixel Rendering for Different Renderers in Processing This sketch demonstrates how to force 1:1 pixel rendering by overriding DPI scaling for JAVA2D in Processing. The solution was a challenging process that required iterating through multiple approaches with both ChatGPT and Google Gemini to finally arrive at a working solution and comments. The key piece of the solution is this static block at the beginning of the sketch, which ensures that Java2D and FX2D renderers…
