While creating test case inputs through the Simulink Test Signal Editor, I encounter the following error:
Time: [0 10]
Data: randn(1920. 1200)
I receive the error: "Data dimensions and time dimensions must be compatible"
Is there a way to create a multi-dimension matrix (in this case, just 2D) as an input for Simulink Test?

Yes, you can create multidimensional signals in the Signal Editor. In your data, every column is treated as a separate "sub"-signal.You are getting this error because the number of rows in your data does not match the number of points in you time vector.
[0 10] is a 1x2 vector, so the Signal Editor expects your data to only have 2 rows, but your data has 1920 rows.
I think the following is what you are looking for
Time: linspace(0, 10, 1920)
Data: randn(1920, 1200)
