Matlab with HiDPI... is still an issue on Linux(?)

96 views (last 30 days)
I wonder if there is a solution for the small interface issue that Matlab has on HiDPI screen under Linux. It is becoming a real messy working intensively, especially with AppDesigner that suffers also because you cannot change the font size in the editor.
Thanks for the help.

No, unfortunately as of R2016b the issue is not resolved.

I accept your answer... both not the fact that matlab developers are underestimating (and they did for LONG time) this issue. I think that it is almost impossible to work for long time with this problem. However, thanks!

MathWorks suggested the following procedure, which works well for me (R2017b). Quoting from their email:
Tuning a high-DPI Linux system requires two steps
  • Setting the MATLAB scale factor
  • Calibrating the system's DPI
The MATLAB scale factor affects MATLAB desktop and the size/position of windows. The system DPI determines the scale and font size of axes and labels. To set the MATLAB scale factor, please use the following MATLAB commands:
>> s = settings;s.matlab.desktop.DisplayScaleFactor
>> s.matlab.desktop.DisplayScaleFactor.PersonalValue = 1.5
To calibrate the system DPI to match the scale facto, please use the following terminal commands :
% xdpyinfo | grep resolution
resolution: 96x96 dots per inch
% xrandr --dpi 144
The DPI value chosen should be the resolution found with xdpyinfo multiplied by the MATLAB scale factor that was set. In the example, 96 × 1.5 = 144.
MATLAB must be restarted after Step 2.

Thank you! Your method works like a charm.

This worked really well for me on Ubuntu 16.04
>> s = settings;s.matlab.desktop.DisplayScaleFactor
>> s.matlab.desktop.DisplayScaleFactor.PersonalValue = 1.5
Additionally, I changed font properties in Preferences -> Font to higher font values.

Has this issue been resolved in R2017a?

I recommend you raise the matter as a support case. Any of the volunteers who might happen to know something about the situation would not be permitted to comment about it.
