Parameter "ScalingFactor" does nothing

[johann-petrak]

Using the Java client, VncViewer-1.10.90.jar on a HiDPI Laptop running Ubuntu 20.04, and with both Java 8.0.265 and 11.0.8. My screen resolution 2880x1620 and my Ubuntu display settings are set to scale to 200% which works for other windows, but not any of the TigerVNC windows.

I have tried --ScalingFactor=auto and --ScalingFactor=200 and various other factors larger and smaller than 100 and the window shown is always exactly the same.

Can you please try adding “-Dsun.java2d.uiScale=200%” before -jar and see if that works?

Very cool, thanks, that did work!

I’ll see if I can make this work without that, but I’m not sure if I have access To a hidpi display

One issue seems to be that “-Dsun.java2d.uiScale=200%” apparently only really supports multiples of 100 which results in a very coarse selection of scalings.

With a recent Ubunty Unity release I think it is possible to use scalings in between as well.

I have tried RealVNC under Windows and there the scaling works even better and the window can change size with proper rescaling arbitrarily. It even adapts to dual monitor configurations with very different DPIs so that about the same portion of the monitor is used when moving it from one to the other.
