I'm not sure, but maybe you can try the `xrandr --scale` option. It will make applications believe that the resolution is different than it really is. It may somehow blur the borders, but with such a high resolution it shouldn't be a problem. For example, assuming that your 3K display output is named LVDS-0: xrandr --output LVDS-0 --scale 0.5x0.5 will make it show the image twice bigger.

One option I thought of would be to create an udev rule that would detect the monitor's connection and trigger a script that would make all the necessary connfiguration changes. What do you guys think?

If you decide to use `xrandr`, the two display outputs will have different names, so there will be independent --scale options: xrandr --output LVDS-0 --scale 0.5x0.5 xrandr --output VGA-0 --scale 1x1 # for illustration purposes: it is the default No need to hack udev! HTH Rodrigo

Thank you very much for your feeback, I've just made a quick check on my VGA screen and it works! I have just a small issue with the font beeing blurry Udev was basically to catch when a monitor is connected so as to trigger a script with an xrandr command to setup the screen connection and resolution.
