Problem:
You want to view a VNC on a screen with a different resolution than the screen you’re viewing (e.g. you want to view your Full HD desktop display on your Notebook).
Usually VNC viewers show scroll bars, but in some cases you need to view the entire screen at once.
Solution:
Install ssvnc – Even if its primary purpose is encrypted VNC, it supports scaling the screen by a given percentage. To access this option using the GUI, select “Options”, “Advanced” and click on “Unix ssvncviewer …” – you’ll see the scale option on the top right.
To use ssvncviewer with scaling on the command line, use the -scale option (replace192.168.3.14 by the host you want to connect to):
ssvncviewer -scale 0.75 192.168.3.14
