Lessee, really pushing the limits of my brain damage but I think that started in Java 9, may not have propagated to any other version and may even only be in the preview. Add -Dsun.java2d.uiScale=2.0 to double it on the command line with a whole numbers like, "3.0", to triple it, has to be found before the UI is initialized. If you're writing it or have the source try System.setProperty("sun.java2d.uiScale", "2.0"); before the party starts or ask google AI about either of those lines. I've probably got it all wrong.

Java swing apps such as the MARS assembly simulator show tiny when I run it on my 2k screen. I found the following will scale it.

java -jar -Dsun.java2d.uiScale=2.0 Mars4_5.jarI think there is another way to scale it? Someone know.
