Comment 0 for bug 1528319

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 greatful 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
