There is no value for "device-scale-factor", but "force-device-scale-factor" has the value I provided when I use the following code:
String[] args = {"--disable-gpu", "--disable-gpu-compositing", "--force-device-scale-factor=1"};
cefApp = CefApp.getInstance(args, settings);
cefApp.addAppHandler(new ApplicationHandler(args));
Now it also has an effect, but not the desired one...
