MATLAB 2019b Simulink 4K Display scaling Linux

It is very easy to scale MATLAB 2018b with the DisplayScaleFactor variable.This works very fine for nearly all systems and applications.

But since 2019b this variable is no longer working for simulink. Simulink is now redesigned and this variable has nolonger an effect on scaling of simulink.

The text and buttons are too small to read and work with them efficiently.

The allready known workarounds do not work.

My working system :

openSUSE Leap 15.1 64-bit with KDE

All updates for system and MATLAB installed

I have exact the same issue with MATLAB R2019b on Linux (Mint 19.3).

With 2020b this Problem is resolved! Upscaling using openSUSE 15.2 with KDE an 4K Monitors works as fine as with 2018b!

Thank you MATLAB Engineers

Hi,

MATLAB is now up to date, but the Problem persists.

[Sai Bhargav Avula]

Hi,

By "MATLAB is upto date" you mean you upgraded to 2020a and the problem persists?

If your window manager is GNOME can you try

navigating to Settings>Devices>Displays>Scale and choose an appropriate value.

If this doesnot solve and If you are using 2019b can you upgrade to 2020a.

If the problem still exits contact technical support by creating a service request.

Hello,

i have two versions of MATLAB. 2018b works fine and 2019b which does not.

Operating system is openSUSE Leap 15.1 with KDE 18.12.

My university only has the b Versions, so the next upgrade i can make would be 2020b.

Hello,

I have a simulare issue on MATLAB 2020b but for a 1080p display and the interface is for me about 2 times bigger.

I'm on Linux too (Pop'OS 20.04 LTS) and the scale of my screen in the Gnome setting is 100%.

Thank you in advance to any one who may be able to give me some help.
