This is a question which has been asked before, but to which I haven't been able to find a satisfactory response. I'm using Matlab R2016b on Linux, with a HiDPI screen (2560x1440) on a laptop - so a lot of pixels squeezed into a small space. And the standard menu fonts are tiny - so tiny that I have to squint carefully to read them.

I understand this to be in some way related to the Java system that Matlab uses for its GUI, but I have no idea how to increase the size of the menubar/toolbar fonts and icons. It's not included in Matlab's preferences; from my reading I believe that these are picked up somehow from the underlying OS. Or more accurately, from the underlying Java engine.

Currently, if I want to use Matlab with readable menus, I have to change my desktop resolution to a lower one, which of course affects every other application. So I'm hoping there's a better way?

Thanks!

The same problem.

Starting 2017b, Matlab supports high DPI display:

Unfortunately the Linux version of MATLAB does not support high DPI screens on Linux yet. Refer this documentation page for more information

http://www.mathworks.com/help/matlab/creating_guis/dpi-aware-behavior-in-matlab.html

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 resolutions of 1920x1080 or as preferred. Follow the steps below to change the screen resolution:

1. Go to the OS Display control setting window

2. Click on the "Display" tab. A slider menu with the title "Scale for menu and title bars:" should be set to either 0.5 or 1. Click Apply.

3. Click on the "Reduce Resolution" tab and set it to 1920 x 1080 (16:9). Click Apply.

@Walter Roberson

The thing with linux is, that anybody who wants and is capable can write their own display manager with graphical environment. Because of that, you'll always be able to identify places where things don't really work in the most optimal way.

That said, as a user of Fedora (with the Gnome display environment), I do not recognise what is put forward in the rant you linked to at all: I have a single central way to control the scaling, and it is accessible from the OS'es configuration menu. I do however recognise that Matlab featurewise is lagging behind on free and open source tools such as VS Code combined, for instance, with the Python ecosystem, and its inability to handle high DPI displays on linux is just an example of that. So even if it is true and some parts of Linux's graphical subsystems may pose a bit of a difficulty for the poor developers over at the Mathworks, it is certainly possible to provide a decent UI experience, as is evidenced by numerous examples.

I understand that Microsoft is a heavyweight software house, but I cannot believe that they can offer an IDE for free that is just a lot better than the IDE that is bundled with Matlab, which costs an arm and a leg to use.

Exactly, and not on IDE's which they make available for free. Yet they manage to do a decent job at it, including the part where high DPI displays are involved, even in the niches of the Linux ecosystem. In shrill contrast, the Mathworks has Matlab as one of their main products which they charge a lot of money for, and they don't even manage to get High DPI display support right for a single dominant Linux distribution.

Bottom line, Mathworks, please, fix the problem. Thank you.

Lame Mathworks. 2024a betas till unable to display a readable help window, way too small Ctrl + + doesn't work on Fedora linux, but Ctrl + - does, which means reducing font size is irreversiblly smaller!
