I have MATLAB 2023b and when I open Simulink, the banner is pixelated and substantially zoomed in. In comparison to the regular MATLAB interface which is crisp and scaled correctly. You can see in the image attached the difference. I am running an NVIDIA RTX 4070 Laptop GPU and am not sure where I can fix this issue.

@George Nehma,
Please check this link of a similar pixelation issue in Simulink.
Additionally, you can try the folowing troubleshooting steps -
1. Adjust High DPI Settings:
  • Right-click on the MATLAB shortcut or executable file.
  • Select Properties.
  • Go to the Compatibility tab.
  • Click on Change high DPI settings.
  • Check the box for Override high DPI scaling behavior and set it to Application.
2. Update GPU Drivers:
  • Ensure that your NVIDIA RTX 4070 drivers are up to date.

Hi Piyush,
Unfortunately none of these seemed to fix the issue and it still persists.

Hi George,
Here are a few more things you can try to fix the pixelation and zoom problems in Simulink as you might have already tried DPI scaling:
  • You can try adjusting the “Display Scale” to check if this resolves the issue you are facing.
If adjusting the “Display Scale” did not resolve the issue for you, I suggest you try the following troubleshooting steps:
  • Check Your Screen Resolution: Make sure your display is set to its highest (native) resolution in Display Settings.
  • Turn Off Hardware Acceleration in Simulink:In MATLAB, go to Home > Preferences > Simulink > Simulation, and uncheck "Use hardware acceleration." Restart MATLAB afterwards. Then, right-click the MATLAB shortcut, go to Properties > Compatibility, and try running it in compatibility mode for Windows 10 or 8, if it’s 11 then assuming that it should have worked.
  • You can also try the setting at matlab.mlsettings/fsroot/settingstree/matlab/desktop/settings.json. It was already there with scaling factor
s = settings;
s.matlab.desktop.DisplayScaleFactor % Check current value
s.matlab.desktop.DisplayScaleFactor.PersonalValue = 1.5:
You can try some values which works the best. Hoping any of this work and help you!
