MATLAB: Matlab with HiDPI… is still an issue on Linux(?)

hidpiinterfaceMATLAB

Hi,

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.

MATLAB: Does MATLAB support High DPI screens on Linux

MATLAB supports High DPI screens on Linux starting from R2017b.

Tuning a high-DPI Linux system requires two steps:

1. Setting the MATLAB scale factor

2. 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.

The two tuning steps are described below:

1. To set the MATLAB scale factor, please execute the following commands in the MATLAB Command Window:

>> s = settings;s.matlab.desktop.DisplayScaleFactor
>> s.matlab.desktop.DisplayScaleFactor.PersonalValue = 1.5

Here the scale factor has been set to 1.5.

2. To calibrate the system's DPI to match the scale factor, 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.

Note:

In earlier releases than R2017b, high DPI screens on Linux is not supported.

The possible workarounds mentioned below may help improve the visual appearance:

(a) You can increase font sizes of text in the different windows. However, the icon or font size of the toolbar cannot be changed.

(b) You can switch the high DPI monitor to a lower screen resolution, for example 1920x1080 or as preferred.

MATLAB: Modified settings (PersonalValue) not persistent across sessions (display scaling)

Thank you @Harsha Priya Daggubati!

Renaming my preference directory to R2019b_old, as suggested in the link that you provided, and letting Matlab create a fresh one solved the problem! Now my preferences are saved across sessions and the display scaling works.
