Hello,

a bug report for my problem was suggested here: https://answers.launchpad.net/ubuntu/+question/274062
I also created a question at askubuntu: http://askubuntu.com/questions/614301/how-to-set-different-scaling-on-multiple-monitors

I'm trying to use an external monitor on my HiDPI Dell XPS 13 9343. It
has a resolution of 3200x1800. The monitor I'm trying to connect has a
resolution of 2560x1440 (or 1920x1080). When using the notebook alone I
need to use a scaling factor of 1,75 due to the high resolution. The
problem occurs when changing the scaling factor for the external
monitor, which is too high with 1,75.

As the GUI settings describe, it is possible to set different scaling
factors for different monitors. Unfortunately the settings always take
effect on all monitors. For example:

Scaling factor: 1
Monitor 3200x1800: everything too small
Monitor: 2560x1440: everything good

Scaling factor 1,75: vice versa

In the question on askubuntu (see above) you can see how the gsettings
are changed when altering the scaling factor. It seems like it is not
possible to set the value separately for each monitor.

I would be grateful if you can check that. I hope all necessary
information are included in the bug report. If not, please describe how
I can help.

Regards,
lum3n
