The simulink window scaling is weird, how to fix it?

matlab版本为2025b，我有三个显示器，发现simulink窗口的缩放比例是按我三个屏幕里面缩放比例设置的最大值（4k但小尺寸屏幕，缩放比例是225是三个屏幕里面最大的）的那个来的，导致在另外两个屏幕上面的窗口大小很奇怪很大，比例很奇怪，甚至点模型设置这个窗口会超出屏幕，只有在4k屏幕上的窗口比例是正常的

如果把4k小屏幕拔掉就正常了，不知道怎么解决

I'm using MATLAB version 2025b and have three monitors. I've noticed that the Simulink window scales according to the maximum scale setting on all three monitors (the smaller 4K monitor has a scale of 225, which is the maximum scale setting on all three). This causes the window on the other two monitors to be unusually large and proportional. Even clicking on the model settings window causes it to extend beyond the screen. Only on the 4K monitor does the window scale appear normal. Unplugging the smaller 4K monitor returns the window to normal. I'm not sure how to fix this.

Hi,

According to my understanding, Simulink windows appears to be oversized on your other monitors. This behavior normalizes when the 4K monitor is disconnected. This can probably be due to MATLAB adopting the highest scaling factor among all monitors for its windows. This can lead to oversized windows on monitors with lower scaling.

Here is a similar MATLAB Answer which you can refer to in order to solve the display scaling issue of Simulink interface: https://www.mathworks.com/matlabcentral/answers/1968389-how-to-change-the-display-scale-factor-of-simulink-interface

You can also try out the following steps in case the issue persists:

• Temporarily set all monitors to use the same scaling factor in the Windows Display Settings. This can prevent the oversized window issue.
• Try setting your primary display (in Windows Display Settings) to the monitor with the scaling factor you prefer Simulink to use. Restart MATLAB after making this change.
• Ensure MATLAB is opened on the monitor with your preferred scaling before opening Simulink models or windows.
